后端：

controller:

 @RequestMapping("/changePassword")public String changePassword(User user,Model m){User user1=userMapper.findUserByName(user.getUsername());if(user1==null) {m.addAttribute("msg","该用户不存在");return "html/changePassword";}String password=request.getParameter("password");if(password==null||password.isEmpty()){m.addAttribute("msg","密码输入时不能为空");return "html/changePassword";}String Repassword=request. getParameter("Repassword");if(Repassword==null||Repassword.isEmpty()){m.addAttribute("msg","密码输入时不能为空");return "html/changePassword";}if(!password.equals(Repassword)) {m.addAttribute("msg", "两次输入的密码不一致");return "html/changePassword";}else{user1.setPassword(password);userMapper.updateByUserName(user.getUsername(),user.getPassword());return "html/login";}}}

Mapper层：

@Mapper
public interface UserMapper extends BaseMapper<User> {@Select(value = "select u.username,u.password from user u where u.username=#{username}")User findUserByName(@Param("username") String username);@Update(value = "update `user` u set  u.password = #{password}  where u.username=#{username}  ")void updateByUserName(@Param("username") String username,@Param("password") String password);}
