           <a href="/user/login" target="top">返回登录</a>
        </div>
    </div>
</div>
</body>
</html>

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);


}
