我正在使用Spring-Boot-1.1.4并使用Java 1.7在Ubuntu 14上运行。 我构建了一个基于MongoDB和嵌入式Tomcat的Web应用程序。 问题是我无法正常关闭我的应用程序，因为有一些阻塞的Tomcat线程。 这是我的主题转储：

虽然有几个关于这个问题的讨论，我找不到我做错了什么，我的意思是，我没有做任何与关机过程有关的事情。 重要的是，该问题不会在Windows上重现。 有人可以告诉我这个吗？
答案 0 :(得分：1)
看起来您在Spring Boot中发现了一个错误。感谢您引起我们的注意。我已经打开an issue来解决这个问题。
我们之前还没有看到这个问题所以我们还没有遇到过您的应用程序或环境问题。你能否就Spring Boot issue评论如何重现问题？
答案 1 :(得分：0)
可以找到完整的答案here
简而言之，我手动配置了Spring Boot应用程序（@EnableAutoConfiguration 禁用），因此，我通过使用构造函数创建调度程序servlet来添加它：
@Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
public DispatcherServlet dispatcherServlet(WebApplicationContext ctx) {
DispatcherServlet dispatcherServlet = new DispatcherServlet(ctx);
return dispatcherServlet;
}
这导致关闭线程被阻止。
