Spring AOP No visible constructors in class - spring-aop

Error: java.lang.IllegalArgumentException: No visible constructors in class org.springframework.hateoas.config.HypermediaSupportBeanDefinitionRegistrar$DefaultObjectMapperCustomizer
Mostly, I used example given in link, and the following code can be found at github repository
Annotation:
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.TYPE)
public #interface NeedTestClass {
}
Aspect:
#After("#args(NeedTestClass)")
public void afterReturningAtArgs() {
log.info("aspect: after #args {}");
}
Service:
#Slf4j
#Component
public class BusinessService {
public void logicWithAnnotatedArgs1(Child c) {
log.info("service");
}
}
Pojo (top class, not sub class):
#NoArgsConstructor // tried with or without
#NeedTestClass
public class Child {}
Test:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration
#WebAppConfiguration
#SpringBootTest
public class AopTest {
#Autowired
private BusinessService myBusinessService;
#Test
public void testAtArgsPCD() {
myBusinessService.logicWithAnnotatedArgs1(new Child());
}
I attempted to examine aop and annotated class inheritance, but it seems the first step could not be ok. I have tried #annotation() and this() PCD both ok.
EDIT:
So far I am wondering maybe the error is related with the bean loading sequence.

Your GitHub project does not even compile. Have you even tested it? First by trial and error I had to add all of these dependencies:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>

<version>0.2.9</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>6.0.6</version>
</dependency>
Next, I noticed that the Maven build does not seem to start the local (127.0.0.1) database because Spring Boot says this at start-up:
(...)

(...)
Would you mind refactoring your GitHub project into an MCVE first before I can check on your actual problem? This way the error is not reproducible.
But having said this, I did notice something in your POM and Java files: Maybe the problem is not where you think it is. I can see that you want to use Lombok in combination with Spring AOP. According to my answer here, there are compatibility problems between AspectJ and Lombok. Maybe they also affect Spring AOP. So can you temporarily test without #Slf4j and other Lombok stuff? As soon as you will have fixed your project I can also test by myself.
Update after GitHub repo project has been repaired:
Now I can build and run your program, thanks. It seems that the parameter is somehow passed through to internal Spring classes you do not wish to target. So just modify your pointcut like this:
#After("#args(com.example.demosm.my.aop.NeedTestClass) && within(com.example.demosm..*)")

java.lang.NoClassDefFoundError: feign/Request$Body in feign while adding support for multipart/form-data

I am trying to proxy multipart request via feign.
#PostMapping(value = "{pathUri1}/{pathUri2}",consumes = MediaType.MULTIPART_FORM_DATA_VALUE,produces = MediaType.APPLICATION_JSON_VALUE)
ResponseEntity<BaseResponse<?>> uploadFileCall(#PathVariable(value = "pathUri1") String pathUri1, #PathVariable(value = "pathUri2") String pathUri2, #RequestPart(name = "file") MultipartFile file, #RequestParam Map<Object,Object> requestParam, #RequestHeader HttpHeaders httpHeaders);
this is service call.

#Autowired
ObjectFactory<HttpMessageConverters> messageConverters;
#Bean
#Primary
#Scope("prototype")
public Encoder feignFormEncoder() {
return new SpringFormEncoder(new SpringEncoder(messageConverters));
}
}
added encoder config for multipart/form-data .
I have followed this
https://github.com/OpenFeign/feign-form
But I am getting hystrixRunTimeException which is caused because of
java.lang.NoClassDefFoundError: feign/Request$Body error.
Use feign-form-spring 3.4.1 version.
Gradle
compile(group: 'io.github.openfeign.form', name: 'feign-form-spring', version: '3.4.1')
Maven
<dependency>

</dependency>
Check requirements https://github.com/OpenFeign/feign-form#requirements
According to the open-feign's github document, Please Note the feign-form's versions:
all feign-form releases before 3.5.0 works with OpenFeign 9.* versions;
starting from feign-form's version 3.5.0, the module works with OpenFeign 10.1.0 versions and greater.
The following config works for me:

How to use org.scalatest.Suite

I'm trying to use scalatest suite using intellij idea like this :
class SampleTest extends org.scalatest.Suite {
def myTest() {
assert(true)
}
}
(new SampleTest).execute()
I have added scalactic_2.11 and scalactic_2.11 to my pom file.The problem is that the SDK still cant resolve it.
Well it seems the problem is due to versioning. using the following version resolved the issue :
<dependency>
<groupId>org.scalatest</groupId>
<artifactId>scalatest</artifactId>
<version>0.9.5</version>
</dependency>

Spring + AngularJS - the server responded with a status of 406 (Not Acceptable) [duplicate]

this is my javascript:
function getWeather() {
$.getJSON('getTemperature/' + $('.data option:selected').val(), null, function(data) {
alert('Success');
});
}
this is my controller:
#RequestMapping(value="/getTemperature/{id}", headers="Accept=*/*", method = RequestMethod.GET)
#ResponseBody
public Weather getTemparature(#PathVariable("id") Integer id){
Weather weather = weatherService.getCurrentWeather(id);
return weather;
}
spring-servlet.xml
<context:annotation-config />
<tx:annotation-driven />
Getting this error:

Interesting note:
I get 406 error, but the hibernate query works meanwhile.
This is what tomcat log says, everytime when I change selection in dropbox:
select weather0_.ID as ID0_0_, weather0_.CITY_ID as CITY2_0_0_, weather0_.DATE as DATE0_0_, weather0_.TEMP as TEMP0_0_ from WEATHER weather0_ where weather0_.ID=?
What could the problem be? There were two similar questions in SO before, I tried all the accepted hints there, but they did not work I guess...
Any suggestions? Feel free to ask questions...
406 Not Acceptable
The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the request.
So, your request accept header is application/json and your controller is not able to return that. This happens when the correct HTTPMessageConverter can not be found to satisfy the #ResponseBody annotated return value. HTTPMessageConverter are automatically registered when you use the <mvc:annotation-driven>, given certain 3-d party libraries in the classpath.
Either you don't have the correct Jackson library in your classpath, or you haven't used the
<mvc:annotation-driven> directive.
I successfully replicated your scenario and it worked fine using these two libraries and no headers="Accept=*/*" directive.
jackson-core-asl-1.7.4.jar
jackson-mapper-asl-1.7.4.jar
I had same issue, with Latest Spring 4.1.1 onwards you need to add following jars to pom.xml.
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.4.1</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.4.1.1</version>
</dependency>
also make sure you have following jar:
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
406 Spring MVC Json, not acceptable according to the request "accept" headers
There is another case where this status will be returned: if the Jackson mapper cannot figure out how to serialize your bean. For example, if you have two accessor methods for the same boolean property, isFoo() and getFoo().
What's happening is that Spring's MappingJackson2HttpMessageConverter calls Jackson's StdSerializerProvider to see if it can convert your object. At the bottom of the call chain, StdSerializerProvider._createAndCacheUntypedSerializer throws a JsonMappingException with an informative message. However, this exception is swallowed by StdSerializerProvider._createAndCacheUntypedSerializer, which tells Spring that it can't convert the object. Having run out of converters, Spring reports that it's not being given an Accept header that it can use, which of course is bogus when you're giving it */*.
There is a bug for this behavior, but it was closed as "cannot reproduce": the method that's being called doesn't declare that it can throw, so swallowing exceptions is apparently an appropriate solution (yes, that was sarcasm). Unfortunately, Jackson doesn't have any logging ... and there are a lot of comments in the codebase wishing it did, so I suspect this isn't the only hidden gotcha.
I had the same problem, my controller method executes but response is Error 406.
I debug AbstractMessageConverterMethodProcessor#writeWithMessageConverters and found that method ContentNegotiationManager#resolveMediaTypes always returns text/html which is not supported by MappingJacksonHttpMessageConverter. The problem is that the org.springframework.web.accept.ServletPathExtensionContentNegotiationStrategy works earlier than org.springframework.web.accept.HeaderContentNegotiationStrategy, and extension of my request /get-clients.html is the cause of my problem with Error 406. I just changed request url to /get-clients.
Make sure that the sent object (Weather in this case) contains getter/setter
Make sure that following 2 jar's are present in class path.
If any one or both are missing then this error will come.
jackson-core-asl-1.9.X.jar jackson-mapper-asl-1.9.X.jar
Finally found answer from here:
Mapping restful ajax requests to spring
I quote:
#RequestBody/#ResponseBody annotations don't use normal view resolvers, they use their own HttpMessageConverters. In order to use these annotations, you should configure these converters in AnnotationMethodHandlerAdapter, as described in the reference (you probably need MappingJacksonHttpMessageConverter).
Check <mvc:annotation-driven /> in dispatcherservlet.xml , if not add it.
And add
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
these dependencies in your pom.xml
Probably no one is scrolling down this far, but none of the above solutions fixed it for me, but making all my getter methods public did.
I'd left my getter visibility at package-private; Jackson decided it couldn't find them and blew up. (Using #JsonAutoDetect(getterVisibility=NON_PRIVATE) only partially fixed it.
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-base</artifactId>
<version>2.6.3</version>
</dependency>
I was having the same problem because I was missing the #EnableWebMvc annotation. (All of my spring configurations are annotation-based, the XML equivalent would be mvc:annotation-driven)
In the controller, shouldn't the response body annotation be on the return type and not the method, like so :
#RequestMapping(value="/getTemperature/{id}", headers="Accept=*/*", method = RequestMethod.GET)
public #ResponseBody Weather getTemparature(#PathVariable("id") Integer id){
Weather weather = weatherService.getCurrentWeather(id);
return weather;
}
I'd also use the raw jquery.ajax function, and make sure contentType and dataType are being set correctly.
On a different note, I find the spring handling of json rather problematic. It was easier when I did it all myself using strings, and GSON.
As #atott mentioned.
If you have added the latest version of Jackson in your pom.xml, and with Spring 4.0 or newer, using #ResponseBody on your action method and #RequestMapping configured with produces="application/json;charset=utf-8", however, you still got 406(Not Acceptable), I guess you need to try this in your MVC DispatcherServlet context configuration:
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager" />
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="false" />
</bean>
That's the way how I resolved my issue finally.
check this thread.
spring mvc restcontroller return json string
p/s: you should add jack son mapping config to your WebMvcConfig class
#Override
protected void configureMessageConverters(
List<HttpMessageConverter<?>> converters) {
// put the jackson converter to the front of the list so that application/json content-type strings will be treated as JSON
converters.add(new MappingJackson2HttpMessageConverter());
// and probably needs a string converter too for text/plain content-type strings to be properly handled
converters.add(new StringHttpMessageConverter());
}
Spring 4.3.10: I used the below settings to resolve the issue.
Step 1: Add the below dependencies
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.6.7</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.7</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
Step 2: Add the below in your MVC DispatcherServlet context configuration:
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>
<bean id="contentNegotiationManager"
class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="false"/>
<property name="favorParameter" value="true"/>
<property name="ignoreAcceptHeader" value="false" />
</bean>
Since spring 3.2, as per the default configuration favorPathExtension is set as true, because of this if the request uri have any proper extensions like .htm spring will give priority for the extension. In step 2 I had added the contentNegotiationManager bean to override this.
make sure your have correct jackson version in your classpath
Check as #joyfun did for the correct version of jackson but also check our headers ... Accept / may not be transmitted by the client ... use firebug or equivalent to check what your get request is actually sending. I think the headers attribute of the annotation /may/ be checking literals although I'm not 100% sure.
Other then the obvious problems I had another one that I couldn't fix regardless of including all possible JARs, dependancies and annotations in Spring servlet. Eventually I found that I have wrong file extension by that I mean I had two separate servlet running in same container and I needed to map to different file extensions where one was ".do" and the other as used for subscriptions was randomly named ".sub". All good but SUB is valid file extension normally used for films subtitle files and thus Tomcat was overriding the header and returning something like "text/x-dvd.sub..." so all was fine but the application was expecting JSON but getting Subtitles thus all I had to do is change the mapping in my web.xml file I've added:
<mime-mapping>
<extension>sub</extension>
<mime-type>application/json</mime-type>
</mime-mapping>
I had the same problem unfortunately non of the solution here solved my problem as my problem was something in a different class.
I first checked that all dependencies are in place as suggested by #bekur
then I checked the request/response that travels from clients to the server all headers was in place an properly set by Jquery.
I then checked the RequestMappingHandlerAdapter MessageConverters and all 7 of them were in place, I really started to hate Spring ! I then updated to from Spring 4.0.6.RELEASE to 4.2.0.RELEASE I have got another response rather than the above. It was Request processing failed; nested exception is java.lang.IllegalArgumentException: No converter found for return value of type
Here is my controller method
#RequestMapping(value = "/upload", method = RequestMethod.POST,produces = "application/json")
public ResponseEntity<UploadPictureResult> pictureUpload(FirewalledRequest initialRequest) {
DefaultMultipartHttpServletRequest request = (DefaultMultipartHttpServletRequest) initialRequest.getRequest();
try {
Iterator<String> iterator = request.getFileNames();
while (iterator.hasNext()) {
MultipartFile file = request.getFile(iterator.next());
session.save(toImage(file));
}
} catch (Exception e) {
return new ResponseEntity<UploadPictureResult>(new UploadPictureResult(),HttpStatus.INTERNAL_SERVER_ERROR);
}
return new ResponseEntity<UploadPictureResult>(new UploadPictureResult(), HttpStatus.OK);
}
public class UploadPictureResult extends WebResponse{
private List<Image> images;
public void setImages(List<Image> images) {
this.images = images;
}
}
public class WebResponse implements Serializable {
protected String message;
public WebResponse() {
}
public WebResponse(String message) {
this.message = message;
}
public void setMessage(String message) {
this.message = message;
}
}
The solution was to make UploadPictureResult not to extend WebResponse
For some reason spring was not able to determine the how to convert UploadPictureReslt when it extended WebResponse
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.8.0</version>
</dependency>
i don't use ssl authentication and this jackson-databind contain jackson-core.jar and jackson-databind.jar, and then change the RequestMapping content like this:
#RequestMapping(value = "/id/{number}", produces = "application/json; charset=UTF-8", method = RequestMethod.GET)
public #ResponseBody Customer findCustomer(#PathVariable int number){
Customer result = customerService.findById(number);
return result;
}
attention:
if your produces is not "application/json" type and i had not noticed this and got an 406 error, help this can help you out.
This is update answer for springVersion=5.0.3.RELEASE.
Those above answers will be only worked older springVersion < 4.1 version. for latest spring you have to add following dependencies in gradle file:
compile group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: fasterxmljackson
compile group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: fasterxmljackson
fasterxmljackson=2.9.4
I hope this will be helpful for who using latest spring version.
Simple answer just add Getter method in your domain/model class.
But Why this works ??
Under the hood Spring used HttpMessageConverters to convert your input JSON to Java Object. The Accept header that is passed in the request is used to select appropriate MessageConvertor at runtime. These message convertors use getter of your domain/model class for conversion, so if there are no getter method, Marshall and unmarshall Java Objects to and from JSON will not happen, even if you add Jackson in your classpath, because even Jackson lib uses Getter methods for marshalling stuffs !!.
Can you remove the headers element in #RequestMapping and try..
Like
#RequestMapping(value="/getTemperature/{id}", method = RequestMethod.GET)
I guess spring does an 'contains check' rather than exact match for accept headers. But still, worth a try to remove the headers element and check.

I don't get this error at all using ChromeDriver, FirefoxDriver and InternetExplorerDriver.
Unfortunately for environmental reasons I have to use HtmlUnitDriver so I'm really scratching my head about this one.
Would be grateful for any suggestions.
EDIT 1:
Have managed to run a portion of this test successfully on my Mac, the remainder times out.
But am not seeing the same errors as above (which were observed on Windows).
Resolved this problem by rebuilding the maven_repo i.e. moving the old one out of the way so maven is forced to rebuild it on the next run of the tests.
The exception no longer appears.

EasyMock 3.0, mocking class throws java.lang.IllegalStateException: no last call on a mock available

Running the following unit test throws the exception: java.lang.IllegalStateException: no last call on a mock available
import org.easymock.*;
import org.junit.*;
public class MyTest {
#Test
public void testWithClass() {
Thread threadMock = EasyMock.createMock(Thread.class);
EasyMock.expect(threadMock.isAlive()).andReturn(true);
}
}
I am not sure what I am doing wrong and can not find any good examples on the web. How do you mock a class using EasyMock 3.0. What is wrong with the above unit test? Any help would be greatly appreciated.
My project includes the following maven dependencies
<dependency>
<groupId>org.easymock</groupId>
<artifactId>easymock</artifactId>
<version>3.0</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib-nodep</artifactId>
<version>2.2</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.objenesis</groupId>
<artifactId>objenesis</artifactId>
<version>1.2</version>
<scope>test</scope>
</dependency>
The reason for this exception is that Thread#isAlive() is a final method, but EasyMock does not support the mocking of final methods. So, the call to this method which appears inside EasyMock.expect(...) is not seen as a "call on a mock".
To mock final methods you would need a different mocking tool, such as JMockit (which I develop):
public void testMockingFinalMethod(#Mocked("isAlive") Thread mock)
{
new Expectations()
{{
mock.isAlive(); result = true;
}};
assertTrue(mock.isAlive());
}
The mocking API doesn't actually require that methods to be mocked are specified explicitly, in the general case. The Thread class is a tricky one, though.
Your test method looks fine, except that you have not prepared the mock object you have created. This has to be done using
EasyMock.replay(mockObject1, mockObject2, ...);
This will prepare the mocked object so that it is the one which will be used on running your JUnit. No issues with your dependencies as well.
Also, you don't seem to be calling the actual method which you are unit-testing here. Usually, the way to write a test method would be to write a JUnit method, using mocking libs
(such as EasyMock and PowerMock) ONLY when there are external objects beyond the test method context, and then replaying all the mocked objects (which prepares the mocks to substitute for the real business objects in the test). After that, you call the actual method you are trying to test, and validate the functionality using org.junit.Assert.assertXXX() methods.
I had multiple calls to EasyMock.replay(mock) within one test case or suite causing this issue, and calling EasyMock.reset(mock) between each solved the problem.
