自学，这写法请问视图在哪表示

package cn.xuxu.login.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import cn.xuxu.login.service.UserServiceImpl;

@Controller
@RequestMapping("/cute")
public class UserController {

@Resource
private UserServiceImpl service;

@RequestMapping("/login.do")
@ResponseBody
public String User(String name) {
    String password = service.checkPassword(name);
    return password;
}

}

return 返回视图的url。

有没有配置视图解析器？
