休眠会陷入无限循环，同时保持具有一对多双向关系的父子实体

Question

我在父实体（应用程序）上调用saveOrUpdate，其中父实体与子对象（审核应用程序）具有一对多的双向映射。 当在父对象上调用saveOrUpdate时，它将进入无限循环，并且堆栈上出现float null错误。 我想保持双向关系不变。

有人可以帮我知道我在做什么错。任何潜在客户都将在这个时候提供很大的帮助。 我在下面提供了完整的代码：

我尝试在关系的子方面使用JsonIgnore批注，但是没有运气。

子实体：auditapplication：

@JsonIgnore
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "MOTS_ID",referencedColumnName = "MOTS_ID", 
    nullable = false, insertable = false, updatable = false)
private Application application;

父实体：应用程序：

@OneToMany(fetch = FetchType.LAZY, mappedBy = "application", cascade = CascadeType.ALL)
Set<AuditApplication> auditApplication;

永久代码：

    Application app = applicationDao.getAppDetailsByMotsId(appOnboardingRequestDTO.getSelectedMotsId());
    if(null != app){
        app.setDirector(appOnboardingRequestDTO.getDirector());
        app.setAvpTower(appOnboardingRequestDTO.getAvpTower());
        app.setOnboarded(true);
        if(null != app.getAuditApplication() && !app.getAuditApplication().isEmpty()){
            //Check if module Id already exists
            List<AuditApplication> existingAuditApps = AuditApplicationPredicate.filterAuditAppliations(app.getAuditApplication(),AuditApplicationPredicate.alreadyExists(appOnboardingRequestDTO.getModuleId()));
            if(null == existingAuditApps || existingAuditApps.isEmpty()){
                AuditApplication auditApp = new AuditApplication();
                auditApp.setApplication(app);
                auditApp.setModuleId(appOnboardingRequestDTO.getModuleId());
                app.getAuditApplication().add(auditApp);
                applicationDao.saveOrUpdate(app);
            }else{
                //Return error message that module already exists
                return "Module Id already exists.";
            }

        }else{
            Set<AuditApplication> auditApplicationSet = new HashSet<AuditApplication>();
            AuditApplication auditApp = new AuditApplication();
            auditApp.setApplication(app);
            auditApp.setModuleId(appOnboardingRequestDTO.getModuleId());
            auditApplicationSet.add(auditApp);
            app.setAuditApplication(auditApplicationSet);
            applicationDao.saveOrUpdate(app);
        }
    }
    return "success";
}
