Following is the code of my example :
@Path("/loginPoint")
@Service
public class UserService {
@Resource(name= "commanUserService")
private CommanUserService commanUserService;
@POST
@Path("/login")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response login(LoginRequest request){
System.out.println("Hello In web Services >>>>>>>>>>>>>>>>>>>>>>>>> ");
LoginResponse response =
commanUserService.getUserloginInformation(request);
return Response.status(Status.OK).entity(response).build();
}
}
LoginRequest.java file code :
@XmlRootElement(name="loginRequest")
public class LoginRequest {
private String userName;
private String password;
@XmlElement("userName")
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
@XmlElement("password")
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
I suppose that problem is in mapping JSON request parameters with
LoginRequest entity, but i am not sure.
