显然缺少 JMS 依赖项，但该项目在 IntellJ 中运行时可以工作。

我已经研究了一段时间可能的解决方案，我发现的所有类似错误都通过添加对 POM.XML 失败的依赖项来解决，我添加了 JMS 依赖项，但错误仍然存在，这里我将 POM.XML 留给你来看看

此错误消息意味着包含此类的 jar 不在应用程序类路径上。添加 spring-data-elasticsearch jar 到它，你的错误应该消失了。

为了避免java中的非法状态异常，应该确保代码中的任何方法都不会在非法或不适当的时间调用。

尝试执行上述任何一种解决方案，它将修复您的解决方案。如果您喜欢这个答案或者您的问题得到了解决，请为我的答案投票。
