我在本地进行了实验，并将spring JPA项目作为jar文件分发到另一台云服务器。然而，云服务器出现错误。原因是什么？

似乎存在同一个 api 被多次调用的问题。为什么会出现这种情况？我该如何修复它？
最佳答案
对我来说，堆栈跟踪看起来就像您多次将“testClientId”添加到您尝试访问的 oauth 服务器中:
Caused by: javax.persistence.NonUniqueResultException: query did not return a unique result: 4
您是否将条目直接添加到数据库中？您是否尝试删除这些条目？
关于java - 查询没有返回唯一结果: 3; nested exception is javax. persistence.NonUniqueResultException:(Spring JPA项目)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60464599/
