有时我在Web应用程序项目中遇到了问题。当我尝试更新Construction Member实体时，Construction Order Id从旧值更改为null。
同时，表“ Construction Member”中没有带有“ Construction Order”的外键，只有Construction Team拥有带有“ Construction Order”的外键
（“施工顺序”>“施工团队”>“施工成员”）
尽管我没有调用任何方法来更新“构造顺序”，但我只使用“构造成员”的数据，并且对这些实体中的每个@ManyToOne都使用了“ updatable = false”，以避免不必要的数据更改。但是错误仍然出现。
注意：当我尝试重新启动服务器时，该错误不存在，并且当我在Web应用程序上处理大量数据时，该错误再次出现，这迫使我再次重新启动服务器以继续使用Web App
-这是我的错误
