JPA一堆多循环引用错误 HttpMessageNotWritableException

发生了一个这样的错误

Resolved exception caused by Handler execution: org.springframework.http.converter.HttpMessageNotWritableException:
Could not write JSON document: Infinite recursion (StackOverflowError)

注意：ManyToOne属性上注解：

@JsonBackReference

没有起作用，在get方法上注解成功解决无线引用导致堆栈溢出的问题。

对onetomany的一方没有加任何的注解也可以从json转换到对象

服务中添加大指标，同时会级联保存

public void addDazhibiao(TESTDazhibiao dazhibiao){    List<TESTXifenzhibiao> xifenzhibiaoList =dazhibiao.getChildren();    if(xifenzhibiaoList !=null) {        for (TESTXifenzhibiao xifen : xifenzhibiaoList                ) {            List<TESTParameter> parameters = xifen.getParameterList();            if(parameters != null) {                for (TESTParameter p : parameters                        ) {                    p.setTESTxifenzhibiao(xifen);                }            }            xifen.setTESTDazhibiao(dazhibiao);        }    }    tesTzhibiaoRepository.save(dazhibiao);}

查询大指标的同时也会级联获取

@Overridepublic List<TESTXifenzhibiao> queryAllXIFENDazhibiao(int fatherid){    List<TESTXifenzhibiao> t = new ArrayList<>();    return t;}
