Spring MVC Controller issue : No mapping found for HTTP request with URI

Yes. I know this is familiar issue. I have looked into other solutions and they didn't help me. I am trying to build Spring MVC Application with Spring 4, Hibernate 5, My Sql and Angular JS 1.x

Problem: As shown in image, When I run the application, it resolved to index.jsp file as expected, then I entered 'http://localhost:8080/TimeLee/user/test' to get web page 'adduser.html' . Boom, it throws following error 'No mapping found for HTTP request with URI [/TimeLee/WEB-INF/views/adduser.html] in DispatcherServlet with name 'mvc-dispatcher'. I checked controller mappings and everything looks good.

UserController:

package com.timelee.users.controllers;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

import com.timelee.users.model.User;
import com.timelee.users.services.UserService;

@RestController
@RequestMapping("/user")
public class UserController
{
    @Autowired
    private UserService userService;

    @RequestMapping(value="/adduser",method=RequestMethod.POST)
    public void saveUser(@RequestBody User user)
    {
        userService.saveUser(user);
    }


    @RequestMapping(value="/getuser",method=RequestMethod.GET)
    public @ResponseBody User getUser(@RequestParam("userId") String userId)
    {
        return userService.getUser(userId);
    }   

    @RequestMapping(value="/test",method=RequestMethod.GET)
    public  ModelAndView test()
    {
        ModelAndView modelAndView=new ModelAndView("adduser");
        return modelAndView;
    }

    @RequestMapping(value="/test2",method=RequestMethod.GET)
    public  String test2()
    {
        return "adduser";
    }

}
