===============================简化JavaBean开发===================================
@NoArgsConstructor//无参构造
//@AllArgsConstructor  //有参构造
@Data//get set方法
@ToString//tostring方法
@EqualsAndHashCode//equals和hashcode方法
public class User {

    private String name;
    private Integer age;

    private Pet pet;

    public User(String name,Integer age){
        this.name = name;
        this.age = age;
    }


}



================================简化日志开发===================================
@Slf4j//日志注解 很方便 直接就可以使用
@RestController
public class HelloController {
    @RequestMapping("/hello")
    public String handle01(@RequestParam("name") String name){
        
        log.info("请求进来了....");
        
        return "Hello, Spring Boot 2!"+"你好："+name;
    }
}
