package com.leju.robot.customer.controller;
    
    import com.leju.robot.common.ResultBean;
    import com.leju.robot.common.util.JsonUtils;
    import com.leju.robot.customer.common.exception.RobotCustomerExceptionFactor;
    import com.leju.robot.customer.model.User;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.http.MediaType;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * Created by Administrator on 2018/7/20.
     */
    @RestController//相当于@controller+@responsebody合起来，如果需要返回的是视图对象，则只需要@controller注解即可
    @RequestMapping("/robot")//拦截路径，比如说在本地启动服务则在浏览器中输入的url是：localhost:8080/robot/user
    public class UserController {
    
        private static final Logger LOGGER = LoggerFactory.getLogger(UserController.class);
    
        @RequestMapping(path = "/user",method = RequestMethod.GET,produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
        public ResultBean<User> getUser(){
            LOGGER.info("输入参数是1");
            User user = new User(1,"李四88");
            LOGGER.info("返回是："+ JsonUtils.toJson(user));
            return new ResultBean<User>(user);
        }
    
        @RequestMapping(path = "/exception",method = RequestMethod.GET,produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
        public ResultBean<User> getException(){
            LOGGER.info("输入参数是1");
            User user = new User(1,"李四88");
            LOGGER.info("返回是："+ JsonUtils.toJson(user));
            throw RobotCustomerExceptionFactor.BUILDING_NOT_EXISTS;
        }
    }
