Java 作为windows服务运行的嵌入式tomcat需要很长时间才能停止服务

我有一个使用嵌入式tomcat（9.0.44）的可执行jar文件。并使用apache

prunsrv

实用程序以windows服务（名为“MyApp测试服务”）运行。 但当我试图停止服务时，需要一些时间（超过一分钟）才能停止服务。但启动这项服务相当快。 我可以确认tomcat的

stop（）

方法很快完成。我怀疑

prunsrv

中还有其他东西等待并需要时间来停止服务。请帮助了解发生了什么以及如何解决此问题（执行

tomcat.stop（）

后立即停止服务）

• 正在注册服务-

  C:\servicestest\prunsrv.exe”“//RS//MyApp测试服务”

• 启动类和方法：

  com.samples.myapp.TestEmbeddedServer:：main

• 关机类和方法：

  com.samples.myapp.TestEmbeddedServer:：stop

从关闭信号发出后的这些日志中可以看出，销毁JVM的延迟正好为1分钟，我认为这就是它挂起的地方

编辑：通过改变Tomcat的版本获得结果

使用Tomcat版本 停下来的时间 ApacheTomcat/8.5.66 约9秒 ApacheTomcat/9.0.1 约9秒 ApacheTomcat/9.0.10 约9秒 ApacheTomcat/9.0.13 约9秒 ApacheTomcat/9.0.14 约1分钟3秒 ApacheTomcat/9.0.16 约1分钟3秒 ApacheTomcat/9.0.20 约1分钟3秒 ApacheTomcat/9.0.30 约1分钟3秒 ApacheTomcat/9.0.40 约1分钟3秒 ApacheTomcat/9.0.44 约1分钟3秒 ApacheTomcat/9.0.46 约1分钟3秒 ApacheTomcat/10.0.6 约1分钟3秒 自Tomcat版本以来，引入了实用程序执行器：

向服务器添加计划执行器，该执行器可用于处理定期实用程序任务。默认情况下，实用程序线程为非守护程序。（remm）

它的线程故意是非守护进程，因此服务器

stop（）

不会关闭JVM。要完全停止服务器，必须使用

destroy（）

：

public void stop（）引发LifecycleException{
this.tomcat.stop（）；
this.tomcat.destroy（）；
}

问题一定出在您的应用程序中（可能它启动了一些非守护进程线程，但在关机过程中没有停止它们）。您是否尝试使用空应用程序？@PiotrP.Karwasz这似乎是tomcat的问题。我尝试了不同版本的tomcat，发现问题是从tomcat 9.0.14开始出现的。对于9.0.14之前的版本，它会很快关闭（只需约9秒）.我已经在有效的问题上添加了我的结果！！现在我可以不用等待一分钟就停止服务了。
