如何在当前机器上运行jvm [英] how to get running jvms in current machine

问题描述

想象一下:两个Java项目正在JDK1.5和JDK1.6上运行 有两个在JDK 1.7上进行. 如何获取正在运行的jvm名称，pid和项目名称就可以了.

Imagine that: Two java projects are work on JDK1.5 and JDK1.6 Two are work on JDK 1.7. How to get the running jvm names, pids and projects name works on it.

结果应该看起来像:

pid 1234，projec_tname prj1，java_version JDK1.6

pid 1234, projec_tname prj1, java_version JDK1.6

pid 4354，projec_tname prj2，java_version JDK1.5

pid 4354, projec_tname prj2, java_version JDK1.5

pid 6234，projec_tname prj3，java_version JDK1.7

pid 6234, projec_tname prj3, java_version JDK1.7

pid 9034，projec_tname prj4，java_version JDK1.7

pid 9034, projec_tname prj4, java_version JDK1.7

中的解决方案在当前计算机上搜索Java的Java库?是在当前计算机上未运行的JDK中找到的.我的问题无济于事.有什么想法吗?

Solution in Is there a Java library that searches for JVMs on the current machine? is find JDKs in current machine which not running. It is not helped for my question. Any ideas?

推荐答案

您正在寻找以下API:

You are looking for this API: http://docs.oracle.com/javase/7/docs/jdk/api/attach/spec/

您必须将tools.jar添加到您的类路径中.

You have to add the tools.jar to your classpath.

这是从以下位置开始的方法:

This is the method to start with: VirtualMachine.list()

id()是特定于提供程序的，但通常是进程ID.

The id()s are provider specific but it’s usually a process id.
