从终端调用Java方法 [英] calling java methods from a terminal

问题描述

假设我有一个Java程序 myProgram.jar ，该程序已在服务器上运行.要启动程序，我将其输入终端:

Suppose I have a java program, myProgram.jar, which I have running on a server. To start the program I would type this into the terminal:

>java -jar myProgram.jar

，该程序将继续无限期运行.现在，如果程序具有诸如

and the program would continue to run indefinitely. Now what about if the program had a function such as

void processInput(String text){
     //process the text
}

，我想通过SSH进入服务器并使用特定字符串调用此函数?因此我可以随时登录服务器并更改程序状态.这可能吗?

and I wanted to SSH into the server and call this function with a particular string? so I could log into my server at any time and alter the state of my program. Is this possible?

推荐答案

可以做到，但不容易.

有一些实现您可能想要的标准方法:MBean.看看 http://docs.oracle.com/javase/tutorial/jmx/mbeans/standard.html

There are standard ways to achieve what you probably want: MBeans. Take a look at http://docs.oracle.com/javase/tutorial/jmx/mbeans/standard.html
