我正在通过XML与SprinBoot/JPA进行集成。我必须读取一个XML文件并将数据保存到我的数据库中。 步骤：Hibernate抛出StackOverflow异常（Spring Boot）
- 我必须验证，如果这个XML不是经常性的，如果它是，我必须更新这个寄存器。
每个XML都带有一个项目列表，我必须验证每个孩子是否已经存在，是否必须更新，如果没有，我必须创建一个新的。
我必须验证某些孩子是否经常性，如果不是，我必须删除此项。
我必须验证材料，颜色和产品是否存在，否则我必须为每种情况创建一个新的。
一般来说，一切工作正常。但我有一些情况下，当我得到一个StackOverflow异常。
这不是因为它是递归的，因为90％的文件被正确保存并正确更新。
我试图分开保存孩子，没有成功。
它总是与抛出异常的文件相同。
这不是内存，因为我有成功案例，该文件比失败的文件大。
我可以多次保存成功文件，并且不会发生错误，但是如果我尝试保存一个有问题的错误并发生异常。
这是我的课负责管理加载XML和持续

为什么你认为你需要两个'@OneToMany（级联= ALL ）'和'@Cascade（ALL）'？ – crizzis
我的错误。我也必须消除渴望。 –
