如何为 Java 程序设置进程名称? [英] How can I set the process name for a Java-program?

问题描述

如果一个 Java 程序被启动，它会在系统进程监控中得到名称 java.许多 Java 程序很难区分.因此，如果存在一种方法来设置名称会很好，这将显示在进程监视器中.我知道这在不同的操作系统上可能会有所不同.

If a Java program is started, it get's in the system process-monitor the name java. Many Java-programs are that way hard to distinguish. So it would be nice, if a way exists, to set the name, that will be shown in the process-monitor. I'm aware that this may work different on different Operating Systems.

一个简单的方法是，如果 java 解释器支持一个开关来设置名称，就像这样:

A simple way would be, if the java-interpreter would support a switch to set the name, like this:

java -processname MyProgram -jar MyProgram

但是我找不到这样的开关，所以它可能不存在.Java 中用于设置进程名称的 API 也可以.

But I couldn't find such a switch, so it is probably non-existant. An API in Java to set the process-name would be also fine.

那么，您有什么建议吗?

So, so you have any suggestions?

推荐答案

我不知道这是否可行，但您可以使用 JDK 附带的名为jps"的命令行工具.它就像 *nix ps，但只是 Java 程序.jps -v 显示你传递给 java 的所有参数.

I don't know if this is possible, but you could use a command line tool that comes with the JDK called 'jps'. It's like *nix ps, but just Java programs instead. jps -v shows all the arguments you have passed to java.

此外，我看到人们通过向 args 添加一个未使用的 -Dmyprocessname 来将进程名称"附加到他们的 java 进程.

Also, I have seen people attach a "process name" to their java processes by adding an unused -Dmyprocessname to the args.
