Spring boot tomcat8 spring boot war内存泄漏

我有一个应用程序正在tomcat8上运行，在反复取消部署/部署（我使用）时，我注意到Tomcat manager上的服务器内存也在增加，单击find leaks显示如下

以下web应用程序已停止（重新加载、取消部署）， 但是它们以前运行的类仍然加载在内存中，因此 导致内存泄漏（使用探查器确认）：/

我试图使用探查器来检查内存中仍然存在的内容，但无法确定，因为我不知道从哪里开始

停止应用程序显示以下日志

如何取消部署/并行部署？我遗漏了什么吗？我指的是tomcat，因为我是如何使用maven tomcat7插件的？你能并行地取消部署/部署吗？我遗漏了什么吗？我指的是tomcat，因为我是如何使用maven tomcat7插件的
