推荐答案

通常，每次执行Java程序都会启动一个新的VM. JVM只不过是Java程序在其中运行的环境.但是，某些程序会创建多个JVM，以便它们可以独立运行许多Java程序.应用程序服务器使您可以选择控制它们启动的JVM的数量以及它们的用途.对于您引用的示例，您可能有3个JVM，但是取决于JBoss的配置方式以及在其中安装的内容，您可能会有更多.

Typically a new VM is started every time you execute a java program. The JVM is nothing more than the environment that the Java program is running in . However, some programs create multiple JVMs so that they can run a number of Java programs independently. Applications servers give you the option to control the number of JVMs they start, and what to use them for. For the example you cited you probably have 3 JVMs, but depending upon how JBoss is configured, and what you have installed there, you might have more.
