===============================简化JavaBean开发===================================
@NoArgsConstructor
//@AllArgsConstructor 有参构造器，使用所有参数生成的构造器
@Data // 自动生成get、set方法
@ToString // 编译类的时候自动生成toString方法
@EqualsAndHashCode
public class User {

    private String name;
    private Integer age;

    private Pet pet;

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