对象存在环形引用时会出现栈溢出

[wf-xian]

对象存在环形引用时会出现栈溢出，示例代码如下：

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;  
@Getter
@Setter
@ToString
public class EntityFirst {
	private EntitySecond second;
}

import lombok.Getter;
import lombok.Setter;
import lombok.ToString; 
@Getter
@Setter
@ToString
public class EntityFirst {
    private EntitySecond second;
}

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
@Getter
@Setter
@ToString
public class EntityLoop {
    private EntityLoop loop;
}

public class FakerObjectTest {
    public static void main(String[] args) {
        User user = DataUtil.build(User.class);
        System.out.println(user.toString());
        EntityFirst first = DataUtil.build(EntityFirst.class);
        System.out.println(first.toString());
        EntityLoop loop = DataUtil.build(EntityLoop.class);
        System.out.println(loop.toString());
    }
}
