Spring boot 弹簧靴Jpa“；无法调用sendError（）；

说明 我正在使用angular 6和spring boot 2.0.1创建一个登录页面。我还使用postgreSQL作为数据库，JPA作为处理程序。在我添加注册功能之前，一切正常，但是在添加新的用户注册功能之后，我开始看到这个错误

Erorr列表（一半）

问题

问题是，即使我收到了这些错误，spring boot仍在更新数据库，并且一切正常。

---

我正在数据库中注册一个新用户，作为创建具有角色的登录系统的一部分。我没有发布代码，因为它太大了，但如果需要，我可以发布。

因此，在经历了大量的讨论之后，我的解决方案是现在不返回“用户角色”（Java集合）。似乎angular在解析web服务返回的JSON时遇到了问题，当它包含角色时，删除它就解决了我的问题。但是，如果其他人有更好的解决方案，请提供帮助
