## 4、测试登录、登出、查询用户接口 ##

**Mybatis 的其他相关类：IUserService UserServiceImpl UserMapper UserMapper.xml**  
**都是简单的查询操作，在这里省略…**

### 4.1 **UserSpringSessionController.java**： ###

package com.jack.controller.portal;
    
    import com.jack.common.Const;
    import com.jack.common.ResponseCode;
    import com.jack.common.ServerResponse;
    import com.jack.pojo.User;
    import com.jack.service.IUserService;
    import org.apache.commons.lang.StringUtils;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.HttpSession;
    
    /** * Created by jack */
    @Controller
    @RequestMapping("/user/springsession/")
    public class UserSpringSessionController { 
    
    
        @Autowired
        private IUserService iUserService;
    
    
        /** * 用户登录 * @param username * @param password * @param session * @return */
        @RequestMapping(value = "login.do",method = RequestMethod.GET)
        @ResponseBody
        public ServerResponse<User> login(String username, String password, HttpSession session, HttpServletResponse httpServletResponse){ 
    
            ServerResponse<User> response = iUserService.login(username,password);
            if(response.isSuccess()){ 
    
                session.setAttribute(Const.CURRENT_USER,response.getData());
            }
            return response;
        }
    
        @RequestMapping(value = "logout.do",method = RequestMethod.GET)
        @ResponseBody
        public ServerResponse<String> logout(HttpSession session,HttpServletRequest httpServletRequest,HttpServletResponse httpServletResponse){ 
    
            session.removeAttribute(Const.CURRENT_USER);
    
            return ServerResponse.createBySuccess();
        }
    
        @RequestMapping(value = "get_user_info.do",method = RequestMethod.GET)
        @ResponseBody
        public ServerResponse<User> getUserInfo(HttpSession session,HttpServletRequest httpServletRequest){ 
    
            User user = (User)session.getAttribute(Const.CURRENT_USER);
    
            if(user != null){ 
                return ServerResponse.createBySuccess(user);
            }
            return ServerResponse.createByErrorMessage("用户未登录,无法获取当前用户的信息");
        }
    
    }

## 5、User类必须实现Serializable ##

package com.jack.pojo;
    
    import lombok.AllArgsConstructor;
    import lombok.Getter;
    import lombok.NoArgsConstructor;
    import lombok.Setter;
    
    import java.io.Serializable;
    import java.util.Date;
    @Getter
    @Setter
    @NoArgsConstructor
    @AllArgsConstructor
    public class User implements Serializable { 
        private Integer id;
    
        private String username;
    
        private String password;
    
        private String email;
    
        private String phone;
    
        private String question;
    
        private String answer;
    
        private Integer role;
    
        private Date createTime;
    
        private Date updateTime;
    }

## 6、其他依赖类：ServerResponse、ResponseCode、Const ##

### 6.1 **ServerResponse.java** ###

            return this.status == ResponseCode.SUCCESS.getCode();
        }
    
        public int getStatus(){ 
            return status;
        }
        public T getData(){

        }
    
    
        public static <T> ServerResponse<T> createByError(){ 
            return new ServerResponse<T>(ResponseCode.ERROR.getCode(),ResponseCode.ERROR.getDesc());
        }
    
    
        public static <T> ServerResponse<T> createByErrorMessage(String errorMessage){ 
            return new ServerResponse<T>(ResponseCode.ERROR.getCode(),errorMessage);
        }
    
        public static <T> ServerResponse<T> createByErrorCodeMessage(int errorCode,String errorMessage){ 
            return new ServerResponse<T>(errorCode,errorMessage);
        }
    
    }

### 6.2 **ResponseCode .java** ###
