controller：
package com.haier.rrs.controller;
@Controller
@RequestMapping("/register")
public class RegisterController {
@Autowired
private UserService userService;
@RequestMapping("/doregister.do")
@ResponseBody
public String doregister(HttpServletRequest request){
String username = request.getParameter("username");
String pwd = request.getParameter("password");
EndecryptUtils endecrypUtil =new EndecryptUtils();
User user=endecrypUtil.md5Password(username, pwd);
int n=userService.registerUser(user);
return "/success.jsp";
}
}
service层 接口service已经@service：
package com.haier.rrs.service.impl;
public class UserServiceImpl implements UserService{
private UserDao userDao;
public UserDao getUserDao() {
return userDao;
}
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
@Override
public User doUserLogin(User user) {
// TODO Auto-generated method stub
return userDao.doUserLogin(user);
}
@Override
public int registerUser(User user) {
// TODO Auto-generated method stub、
String username="1";
List<User> lt = new ArrayList();
lt=userDao.selectAll();
List<User> us=userDao.selectId(username);
int n=userDao.addUser(user);
return n;
}
}
Dao层：
package com.haier.rrs.dao;
@Repository
public interface UserDao {
List<User> selectId(@Param(value = "username") String username);
public User doUserLogin(User user);
public int addUser(User user);
List<User> selectAll();
}

我也不知道哪出问题了，网上的都试了，不行
