类型“消息：JAR条目META-INF / services / *未在/ <service.jar>中找到”的例外情况
我有一个基于springboot的微服务，它从SOAP端点读取XML，解析它并将解析后的响应转发给请求客户端。
以下是使用的springboot / spring / tomcat版本：
<spring.boot.version>1.5.4.RELEASE</spring.boot.version>
<spring.version>4.3.9.RELEASE</spring.version>
Tomcat 8.5.21.0
该服务在功能上运行良好，并且能够处理负载而没有太多问题。但是，当我查看该服务的航班记录时，我看到很多（每分钟百万分钟）的例外情况如下所示：

具体的例外似乎是：
Message: JAR entry META-INF /services/* not found in /<service.jar>
异常数量会给服务带来很大的内存压力，从而限制了服务的性能/可扩展性
我尝试寻找解决方案，并发现了一些类似的问题。大多数资源都指向嵌入式tomcat作为问题。但我无法在任何地方找到这个特定问题的原因或解决方案。
非常感谢任何理解/解决此问题的帮助！
