我正在尝试在tomcat服务器上部署我的springboot应用程序，将其编译为.war，在启动项目时收到以下错误

显然缺少 JMS 依赖项，但该项目在 IntellJ 中运行时可以正常工作。

一段时间以来，我一直在研究一种可能的解决方案，我发现的所有类似错误都是通过将失败的依赖项添加到POM.XML来解决的，我添加了JMS依赖项，但错误仍然存在，在这里我留下我的POM.XML供您查看

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

为了避免 java 中的非法状态异常，应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，或者您的问题已解决，请投票给我的答案。

您好，您的意思是“spring-boot-starter-data-elasticsearch”依赖项？为什么我不使用它，错误来自 JMS 类
