org.springframework.data.mongodb.core.convert.MappingMongoConverter.writeInternal(MappingMongoConverter.java:497) 到org.springframework.data.mongodb.core.convert.MappingMongoConverter.writeInternal(MappingMongoConverter.java:744)来回递归调用了
于是在这两个位置下了个断点。发现代码执行到转换这个对象时一直递归，每个对象里面有个childrenList层层递归到栈溢出。
于是就查找该对象来源，由于在异步线程中抓取得对象已经被加工过了，并不知道原始对象为哪个，此线程里面得数据来源于方法切面前后拦截到得对象，于是找到切面方法，下了个断点查看每个被切得方法，是否有logger对象。
发现Logger[com.odianyun.finance.model.vo.PagerRequestVO]该对象包含了一个logger，于是将该logger删除之后，在测试以下，果然不溢出了。
