场景：

		<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.44</version>
        </dependency>

想要在实体类中写一个克隆方法

public AdtrackReportCard getObjectClone() {
        return new AdtrackReportCard(this.name , this.type , this.pf , this.imf , this.clf , this.dataSource) ;
    }

自己写的克隆方法或者继承clone接口实现的克隆 都报错

java.lang.StackOverflowError: null
at com.alibaba.fastjson.serializer.ASMSerializer_2_AdtrackReportCard.writeNormal(Unknown Source)

at com.alibaba.fastjson.serializer.JavaBeanSerializer.write(JavaBeanSerializer.java:411)
at com.alibaba.fastjson.serializer.JavaBeanSerializer.write(JavaBeanSerializer.java:120)

解决

我的解决方案是 换个类中写克隆方法
