(用户名从session获取，然后根据用户名查询对应user信息做验证)

UserController
1 /** 2 * 修改密码功能实现 3 * @param userName 4 * @param oldPassword 5 * @param newPassword 6 7 * @return 8 */ 9 @PostMapping("/changePassword") 10 @ResponseBody 11 public Results changePassword(@RequestParam("userName") String userName, 12 @RequestParam("oldPassword") String oldPassword, 13 @RequestParam("newPassword") String newPassword){ 14 SysUser user = userService.findByUserByUserName(userName); 15 if (user == null){ 16 return Results.failure(1,"用户不存在！"); 17 } 18 if (!Md5Cipher.encryptWithSalt(oldPassword).equals(user.getPassWord())){ 19 return Results.failure(1,"旧密码错误！"); 20 } 21 return userService.changePassword(userName,newPassword); 22 }
UserService
Results changePassword(String userName, String newPassword);
UserServiceImpl
1 @Override 2 public Results changePassword(String userName,String newPassword) { 3 userDao.changePassword(userName,Md5Cipher.encryptWithSalt(newPassword)); 4 return Results.success(); 5 }
UserDao
int changePassword(@Param("userName") String userName,@Param("password") String password);
UserMapper.xml
1 <!--修改密码--> 2 <update id="changePassword"> 3 update sys_user set password=#{password} where user_name = #{userName} 4 </update>
测试----
退出功能比较简单--移除session保存的user，重定向到登录页面
LoginController
1 @GetMapping("/exit") 2 public String exit(HttpServletRequest request){ 3 request.getSession().removeAttribute("user"); 4 return "redirect:/login"; 5 }
