Spring 未与父ID映射的多工单
我正在尝试在我的spring boot应用程序中实现测试，但我在许多One/OneToMany链接方面遇到了问题 似乎没有创建子对象的链接，而我使用CascadeType=ALL 我尝试在BusinesDomain.addSubdomain中创建它，添加“subDomain.domain（this）；”，但这会导致循环 我发现其他话题也有同样的错误，但似乎没有一个涵盖了我的问题 你能帮我找出问题所在吗 非常感谢 这里是我的实体Spring 未与父ID映射的多工单,spring,hibernate,jpa,spring-boot,Spring,Hibernate,Jpa,Spring Boot,我正在尝试在我的spring boot应用程序中实现测试，但我在许多One/OneToMany链接方面遇到了问题 似乎没有创建子对象的链接，而我使用CascadeType=ALL 我尝试在BusinesDomain.addSubdomain中创建它，添加“subDomain.domain（this）；”，但这会导致循环 我发现其他话题也有同样的错误，但似乎没有一个涵盖了我的问题 你能帮我找出问题所在吗 非常感谢 这里是我的实体 import lombok.AccessLevel; import
