如何管理JMX Web应用程序

I've gone through the process on this page to expose the JMX interface of a web application.

我已经浏览了此页面上的过程以公开Web应用程序的JMX界面。

I've managed to view the exposed interface on the Tomcat JMX proxy but when I load JConsole and look for the exposed mbean interface I can't find anything related to the attributes and operations exposed.

我已经设法在Tomcat JMX代理上查看公开的接口,但是当我加载JConsole并查找公开的mbean接口时,我找不到与公开的属性和操作相关的任何内容。

Thre is no specific entry on jconsole for the web app so I figured it might be under the TOMCAT jmx entry. It's not. (bare in mind, I did manage to see it on the tomcat jmx proxy page).

在网络应用程序的jconsole上没有特定条目,所以我认为它可能在TOMCAT jmx条目下。不是。 (记住,我确实设法在tomcat jmx代理页面上看到它)。

How can I manage my web application locally? Why is JConsole not showing it?

如何在本地管理我的Web应用程序?为什么JConsole没有显示它?

I've managed to fix this by doing a few basic steps -

我已经设法通过做一些基本步骤来解决这个问题 -

In the webapp context listener contextInitialized method, I instantiated a singleton class that will run and implement the mbean (the servlet itself cannot implement an mbean because it only wakes up to take requests from the server).

在webapp上下文侦听器contextInitialized方法中,我实例化了一个将运行并实现mbean的单例类(servlet本身无法实现mbean,因为它只会唤醒来自服务器的请求)。

The servlet "informs" the singleton of every operation that we want to monitor and the singleton is the one that actually reports this through jmx.

servlet“通知”我们要监视的每个操作的单例,单例是通过jmx实际报告的单例。

In the singleton I registered with the mbean server with this command:

在使用此命令在mbean服务器上注册的单例中:

ManagementFactory.getPlatformMBeanServer().registerMBean(this, name);

Thats it. (In a nut shell)

而已。 (简而言之)
