5、用户模块接口开发——登录、注销和注册

本文主要是介绍5、用户模块接口开发——登录、注销和注册，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

先看一下工程目录
在这里插入图片描述
创建UserController类

在主方法上加上这两个注释：

@Controller
@RequestMapping("/user/")

如
在这里插入图片描述
1、登录接口：
Controller: 层

//登录@RequestMapping(value = "login.do",method = RequestMethod.POST)@ResponseBodypublic ServerResponse<User> login(String username, String password, HttpSession session){//service>> mybatis>>daoServerResponse<User> response= iUserService.login(username,password);if(response.isSussecc()){session.setAttribute(Const.CURRENT_USER,response.getData());}return response;}

Service：层

  //登录@Overridepublic ServerResponse<User> login(String username, String password) {int resultCount= userMapper.checkUsername(username);if(resultCount==0){return ServerResponse.createByErrorMessage("用户名不存在");}//TODO 密码登录MD5String md5Password=MD5Util.MD5EncodeUtf8(password);User user=userMapper.selectLogin(username,password);if(user==null){return  ServerResponse.createByErrorMessage("密码错误");}user.setPassword(StringUtils.EMPTY);return ServerResponse.createBySuccessMessage("登录成功",user);}

2、注销接口：
Controller 层：

//注销  删除里面的Session即可@RequestMapping(value = "logout.do",method = RequestMethod.GET)@ResponseBodypublic ServerResponse<String> logout(HttpSession session){session.removeAttribute(Const.CURRENT_USER);return ServerResponse.createBySuccess();}

由于只要删除Session,所以不需要涉及到Service层。
3、注册接口：
Controller : 层

  //注册@RequestMapping(value = "regiest.do",method = RequestMethod.POST)@ResponseBodypublic ServerResponse<String> regiest(User user){return iUserService.regiest(user);}//校验邮箱或用户名不否能用@RequestMapping(value = "check_valid.do",method = RequestMethod.POST)@ResponseBodypublic ServerResponse<String> checkValid(String str,String type){return iUserService.checkValid(str,type);}Service 层//注册方法@Overridepublic ServerResponse<String> regiest(User user){//复用下面的checkValid校验方法ServerResponse validRespose=this.checkValid(user.getUsername(),Const.USERNAME);if(!validRespose.isSussecc()){return validRespose;}validRespose=this.checkValid(user.getEmail(),Const.EMAIL);if(!validRespose.isSussecc()){return validRespose;}user.setRole(Const.Role.ROLE_CUSTOMER);//MD5加密user.setPassword(MD5Util.MD5EncodeUtf8(user.getPassword()));int resultCount=userMapper.insert(user);if(resultCount==0){return ServerResponse.createByErrorMessage ("服务器内部错误，注册失败");}return ServerResponse.createBySuccessMessage("注册成功");}//判断用户名和邮箱是否有效public ServerResponse<String> checkValid(String str,String type){if(StringUtils.isNotBlank(type)){//开始校验if(Const.USERNAME.equals(type)){int resultCount= userMapper.checkUsername(str);if(resultCount>0){return ServerResponse.createByErrorMessage("用户名已存在");}}if(Const.EMAIL.equals(type)){int resultCount=userMapper.checkEmail(str);if(resultCount>0){return ServerResponse.createByErrorMessage("email已存在");}}}else{return ServerResponse.createByErrorMessage("参数错误");}return ServerResponse.createBySuccessMessage("校验成功");}
