在单独的进程中执行Java应用程序

本文介绍了在单独的进程中执行Java应用程序的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

Java应用程序是否可以使用其名称(而不是其位置)以独立于平台的方式在单独的进程中加载​​?

Can a Java application be loaded in a separate process using its name, as opposed to its location, in a platform independent manner?

我知道您可以执行程序通过......

I know you can execute a program via ...

Process process = Runtime.getRuntime().exec( COMMAND );

...此方法的主要问题是此类调用是特定于平台的。

... the main issue of this method is that such calls are then platform specific.



理想情况下,我将方法包装成简单的方法...


Ideally, I'd wrap a method into something as simple as...

EXECUTE.application( CLASS_TO_BE_EXECUTED );

...并将应用程序类的完全限定名称传递为 CLASS_TO_BE_EXECUTED

... and pass in the fully qualified name of an application class as CLASS_TO_BE_EXECUTED.

推荐答案

两个提示:

System.getProperty(java.home)+/ bin / java为您提供java可执行文件的路径。

System.getProperty("java.home") + "/bin/java" gives you a path to the java executable.

((URLClassLoader)Thread.currentThread()。getContextClassLoader())。getURL()帮助您重建当前应用程序的类路径。

((URLClassLoader) Thread.currentThread().getContextClassLoader()).getURL() helps you to reconstruct the classpath of current application.

然后你的 EXECUTE.application 只是(伪代码):

Then your EXECUTE.application is just (pseudocode):

Process.exec(javaExecutable, - classpath,urls.join(:),CLASS_TO_BE_EXECUTED)
