Dependency Injection not working in Wildfly-Swarm-2016.12.1 - wildfly-swarm

Question

I am a newbie to the wildfly-swarm. I was able to prep a basic JAX-RS application in swarm, and worked like a charm. But when I'd tried to introduce CDI to my app, everything went wrong. The Bean Injection is not working!. I'm getting NULLPointerException in places where I'd tried to invoke the bean methods. I'd tried all possible solutions, that I could find over web. But nothing worked. Following is my pom.xml config;

and following is my Main class;
public class BootStrap {

public static void main(String[] args) {
try {
Swarm swarm = new Swarm(true);
JAXRSArchive deployment = ShrinkWrap.create(JAXRSArchive.class, "jax_cdi_microprofile");
deployment.addClass(RESTEntryManager.class).addClass(HTML5Generator.class)
.addClass(HattsACKTestService.class)
.addAsWebInfResource(new StringAsset(new StringBuilder("<?xml version=\"1.0\"?>")
.append(" <beans bean-discovery-mode=\"all\" version=\"1.1\" ")
.append(" xmlns=\"http://xmlns.jcp.org/xml/ns/javaee\"")
.append(" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"")
.append(" xsi:schemaLocation=\"http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd\"/>")
.toString()), "beans.xml")
.addAllDependencies();
swarm.start().deploy(deployment);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
and following is my JAX-RS resource declaration;
#Path("/handshake-test")
#Stateless
public class HattsACKTestService {
#Resource(lookup = "java:jboss/ee/concurrency/executor/default")
private ManagedExecutorService managedExecutorService;
#Inject
private Authenticator authenticator;
public HattsACKTestService() {
// INTENTIONALLY LEFT AS BLANK
}
#GET
public void handshake(#Suspended AsyncResponse asyncResponse) {
/*
* new Thread(() -> {
*
* HTML5Generator html5Generator = new HTML5Generatorg.Builder()
* .setPageTitle("HATTS Handshake Service Response").appendPageBody(
* "H1", "Handshake Initiated...") .build();
*
* asyncResponse.resume(html5Generator.getContentBuilder().toString());
*
* }).start();
*/
/*managedExecutorService.submit(() -> {
asyncResponse.resume("Hi World!!!.. This is Wildfly in CDI !!!");
});*/
asyncResponse.resume(authenticator.authenticate());
}
}
and following is the Authenticator bean;
#Stateless
public class Authenticator {
/**
*
*/
public Authenticator() {
// TODO Auto-generated constructor stub
}
public String authenticate() {
return "Authenticated !!";
}
}
Not even the ManagedExectorService is injected!. Could any one help me to sort this out ?

Answer 1

Your Maven dependencies need to be:
<dependency>
<groupId>org.wildfly.swarm</groupId>
<artifactId>jaxrs</artifactId>
</dependency>
<dependency>
<groupId>org.wildfly.swarm</groupId>
<artifactId>cdi</artifactId>
</dependency>
weld was renamed to cdi a few releases ago, and jaxrs-cdi is no longer explicitly needed. It's brought in for you.
With what you have in a custom main(), I'd recommend not using one at all and just letting WF Swarm create your deployment for you.
