import org.springframework.web.bind.annotation.RestController;

import com.npf.springboot.entity.User;

/**
 * 
 * @author Jack
 *
 */
@RestController
public class UserController {
    
    /**
     * spring boot默认使用的json解析框架是jackson
     * @return
     */
    @RequestMapping("/getUser")
    public User getUser(){
        User user = new User();
        user.setId(1);
        user.setName("Jack");
