How can I give my Java application a unique process name?
提问by Daniel Rikowski
I've noticed that when I start Netbeans it shows up in the task manager as netbeans.exeas all my own Java applications show up as java.exeor javaw.exe.
我注意到当我启动 Netbeans 时，它显示在任务管理器中，netbeans.exe就像我自己的所有 Java 应用程序都显示为java.exe或 一样javaw.exe。
How can I change that so my process names shows up as myapp.exe?
我该如何更改，以便我的进程名称显示为myapp.exe？

Netbeans and Eclipse both ship with an .exe file that in turns launches a JVM. The exe itaself probably does nothing after launching the VM. You see the NetBeans javaw.exe in the Task Manager also, I suspect.
Netbeans 和 Eclipse 都附带一个 .exe 文件，该文件依次启动 JVM。启动虚拟机后，exe 本身可能什么都不做。我怀疑您还会在任务管理器中看到 NetBeans javaw.exe。
So you'll need to write a native exe (using some windows tool) that does a similar thing.
因此，您需要编写一个执行类似操作的本机 exe（使用某些 Windows 工具）。

Not easily. The easiest way (but not nice!) would be to simply copy the java.exe (only 68k on my system, so perhaps practical!)
不容易。最简单的方法（但不是很好！）是简单地复制 java.exe（我的系统上只有 68k，所以也许实用！）
If you're worried about identifying which java process is which (e.g. is one consuming memory/CPU etc.), use the standard tool jpsto identify the Java processes
如果您担心确定哪个 Java 进程是哪个（例如，一个消耗内存/CPU 等），请使用标准工具jps来识别 Java 进程

IMO the best option is to choose one of the many open source launchers. They all provide a nicer deployment container than java.exe and a batch file.
IMO 的最佳选择是选择众多开源启动器之一。它们都提供了比 java.exe 和批处理文件更好的部署容器。
I've compiled a list of them after a brief search on google (in no particular order and may not be exhaustive):
我在谷歌上进行了简短的搜索后整理了一份清单（没有特定的顺序，也可能不是详尽无遗）：

Just answered this a second ago here: Get JVM to grow memory demand as needed up to size of VM limit?
刚刚在这里回答了这个问题：Get JVM to increase memory demand as needed up to size of VM limit?
It's actually a loteasier than folks are saying (but you do have to have a c/c++ compiler handy).
它实际上比人们说的要容易得多（但你必须手头有 ac/c++ 编译器）。

There are mainly 2 approaches: one is as already described: using tools like Launch4j, WinRun4J to create native Windows launchers.
主要有两种方法：一种是已经描述过的：使用 Launch4j、WinRun4J 等工具创建本地 Windows 启动器。
Another approach that seems better is to use Apache Procrun to wrap the java application as a Windows service. During the install service process, we can give the process an meaningful name such as OurApp.exe.
另一种看起来更好的方法是使用 Apache Procrun 将 java 应用程序包装为 Windows 服务。在安装服务过程中，我们可以给这个进程一个有意义的名字，比如OurApp.exe。
All we need do is rename prunsrv.exe to OurApp.exe and replace every occurrence of prunsrv.exe in our install|start|stop|uninstall service scripts to MyApp.exe.
我们需要做的就是将 prunsrv.exe 重命名为 OurApp.exe，并将我们的 install|start|stop|uninstall 服务脚本中出现的每个 prunsrv.exe 替换为 MyApp.exe。
