#RestController VS #Controller in Spring MVC with AngularJs - angularjs

Question

I want to create an application with Spring MVC Rest Web services and angularJs.
So my probleme is when i put in my controller #Controller everythings works (I have my page home1.jsp) but when i use #RestController my browser display a String ("home1").
Can you please help to understand my probleme, Thanks.
Here is my code:
*AppController
#RestController
#RequestMapping("/service")
public class AppController {
#Autowired
MyService myService;
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
/**
* Simply selects the home view to render by returning its name.
*/
#RequestMapping(value = "/home1", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate );
return "home1";
}
// GET ALL
#RequestMapping(value="/allProfiles",method = RequestMethod.GET,headers="Accept=application/json")
public List<Profil> getProfils()
{
System.out.println("RestControllern methode initialized");
return myService.getAllProfiles();
}
#RequestMapping(value="/allPatterns",method = RequestMethod.GET,headers="Accept=application/json")
public #ResponseBody List<Pattern> getPatterns()
{
logger.info("Welcome home! allPatterns {}.");
System.out.println("RestControllern methode initialized");
Pattern p = new Pattern();
p.setId(5);
p.setValue("moiuuyyt");
return myService.getAllPattern();
}
#RequestMapping(value="/allComponents",method = RequestMethod.GET,headers="Accept=application/json")
public List<Component> getComponents()
{
return myService.getAllComponent();
}
//GET ONE
#RequestMapping(value="/components/{id}",method = RequestMethod.GET,headers="Accept=application/json")
public Component getComponent(#PathVariable int id)
{
return myService.getComponentById(id);
}
#RequestMapping(value="/profiles/{id}",method = RequestMethod.GET,headers="Accept=application/json")
public Profil getProfil(#PathVariable int id)
{
return myService.getProfilById(id);
}
#RequestMapping(value="/patterns/{id}",method = RequestMethod.GET,headers="Accept=application/json")
public Pattern getPattern(#PathVariable int id)
{
return myService.getPatternById(id);
}
//SAVE
#RequestMapping(value="/addpattern/{value}",method= RequestMethod.POST, headers="Accept=application/json")
public String addPattern(#PathVariable String value)
{
Pattern pat = new Pattern();
pat.setValue(value);
myService.addPattern(pat);
return "redirect:/service/allPatterns";
}
#RequestMapping(value="/addprofil",method = RequestMethod.POST,headers="Accept=application/json")
public void addProfil()
{
Profil pr = new Profil();
pr.setProfilName("Profil1");
myService.addProfil(pr);
}
#RequestMapping(value="/addcomponent",method = RequestMethod.POST,headers="Accept=application/json")
public void addComponent(Component cp)
{
myService.addComponent(cp);
}
public MyService getMyService() {
return myService;
}
public void setMyService(MyService myService) {
this.myService = myService;
}
/**
* #return The page of all Patterns after we have updated one of them to test the method
*/
#RequestMapping(value="/updatepattern/{i}/{value}",method= RequestMethod.PUT, headers="Accept=application/json")
public String updatePattern(#PathVariable int i,#PathVariable String value)
{
/*List<Pattern> liste = myService.getAllPattern();
Pattern p = liste.get(0);
p.setValue("^/[0-9]Pattern has been updated");
myService.updatePattern(p);*/
Pattern p = myService.getPatternById(i);
p.setValue(value);
myService.updatePattern(p);
return "redirect:/service/home1";
}
/**
* #return The page of all Patterns after we have deleted one of them to test the method
*/
#RequestMapping(value="/deletepattern/{id}",method= RequestMethod.DELETE, headers="Accept=application/json")
public String DeletePattern(#PathVariable int id)
{
/*List<Pattern> liste = myService.getAllPattern();
Pattern p = liste.get(3);*/
Pattern p = myService.getPatternById(id);
myService.deletePattern(p);
return "redirect:/service/home1";

Answer 1

When using #RestController annotation, all #RequestMapping methods assume #ResponseBody semantics by default. That's why home1 is being returned as String. If you are mixing a JSP view and Responsebody, then i would suggest to go with #Controller annotation.
