Spring MVC PUT Request returns 405 Method Not Allowed

I am using spring mvc to set up a rest api and most of the configurations are set up automatically through the spring boot project. On the front end I am using angularjs and

Your problem is that the endpoints for findById and updateUser are the same which is api/users/{id} and since the one with GET method comes first it will be evaluated first when you send a PUT request and hence will be rejected by spring.

I suggest you change the endpoint for updating user to api/users/update/{id} as below:

@Controller
@RequestMapping("/api/users")
public class UserController {

    @Inject
    UserService svc;

    @RequestMapping(method = RequestMethod.GET)
    @ResponseBody
    public List home() {
        return svc.findAll();
    }

    @RequestMapping(method = RequestMethod.GET, value = "/{id}")
    @ResponseBody
    public User findById(@PathVariable long id){
        return svc.findById(id);
    }

    @RequestMapping(method = RequestMethod.PUT, value="/update/{id}")
    @ResponseBody
    public User updateUser(@PathVariable long id, @RequestBody User user){
        Assert.isTrue(user.getId().equals(id), "User Id must match Url Id");
        return svc.updateUser(id, user);
    }

}
