如何从 Java 中查找和终止正在运行的 Win-Processes？

How to find and kill running Win-Processes from within Java?

提问by GHad

I need a Java way to find a running Win process from which I know to name of the executable. I want to look whether it is running right now and I need a way to kill the process if I found it.

我需要一种 Java 方法来查找正在运行的 Win 进程，从中我知道可执行文件的名称。我想看看它现在是否正在运行，如果找到它，我需要一种方法来终止该进程。

You can use command line windows tools tasklistand taskkilland call them from Java using Runtime.exec().

您可以使用命令行窗口工具tasklist，taskkill并使用Runtime.exec().

You will have to call some native code, since IMHO there is no library that does it. Since JNI is cumbersome and hard you might try to use JNA (Java Native Access). https://jna.dev.java.net/

您将不得不调用一些本机代码，因为恕我直言，没有库可以做到这一点。由于 JNI 既麻烦又困难，您可能会尝试使用 JNA（Java Native Access）。https://jna.dev.java.net/

You could use a command line tool for killing processes like SysInternals PsKilland SysInternals PsList.

您可以使用命令行工具来终止SysInternals PsKill和SysInternals PsList 等进程。

You could also use the build-in tasklist.exe and taskkill.exe, but those are only available on Windows XP Professional and later (not in the Home Edition).

您也可以使用内置的 tasklist.exe 和 taskkill.exe，但这些仅适用于 Windows XP Professional 及更高版本（不适用于家庭版）。

Use java.lang.Runtime.execto execute the program.

使用java.lang.Runtime.exec执行程序。

private static final String TASKLIST = "tasklist";
private static final String KILL = "taskkill /F /IM ";

public static boolean isProcessRunning(String serviceName) throws Exception {

 Process p = Runtime.getRuntime().exec(TASKLIST);
 BufferedReader reader = new BufferedReader(new InputStreamReader(
   p.getInputStream()));
 String line;
 while ((line = reader.readLine()) != null) {

  System.out.println(line);
  if (line.contains(serviceName)) {
   return true;
  }
 }

 return false;

}

public static void killProcess(String serviceName) throws Exception {

  Runtime.getRuntime().exec(KILL + serviceName);

 }

EXAMPLE:

例子：

public static void main(String args[]) throws Exception {
 String processName = "WINWORD.EXE";

 //System.out.print(isProcessRunning(processName));

 if (isProcessRunning(processName)) {

  killProcess(processName);
 }
}

Here's a groovy way of doing it:

这是一个很好的方法：

final Process jpsProcess = "cmd /c jps".execute()
final BufferedReader reader = new BufferedReader(new InputStreamReader(jpsProcess.getInputStream()));
def jarFileName = "FileName.jar"
def processId = null
reader.eachLine {
    if (it.contains(jarFileName)) {
        def args = it.split(" ")
        if (processId != null) {
            throw new IllegalStateException("Multiple processes found executing ${jarFileName} ids: ${processId} and ${args[0]}")
        } else {
            processId = args[0]
        }
    }
}
if (processId != null) {
    def killCommand = "cmd /c TASKKILL /F /PID ${processId}"
    def killProcess = killCommand.execute()
    def stdout = new StringBuilder()
    def stderr = new StringBuilder()
    killProcess.consumeProcessOutput(stdout, stderr)
    println(killCommand)
    def errorOutput = stderr.toString()
    if (!errorOutput.empty) {
        println(errorOutput)
    }
    def stdOutput = stdout.toString()
    if (!stdOutput.empty) {
        println(stdOutput)
    }
    killProcess.waitFor()
} else {
    System.err.println("Could not find process for jar ${jarFileName}")
}

small change in answer written by Super kakes

Super kakes 写的答案的小变化

private static final String KILL = "taskkill /IMF ";

Changed to ..

变成 ..

private static final String KILL = "taskkill /IM ";

/IMFoption doesnot work .it does not kill notepad..while /IMoption actually works

/IMF选项不起作用。它不会杀死记事本..而/IM选项实际上有效

Use the following class to kill a Windows process(if it is running). I'm using the force command line argument /Fto make sure that the process specified by the /IMargument will be terminated.

使用以下类来终止 Windows 进程（如果它正在运行）。我正在使用 force 命令行参数/F来确保该/IM参数指定的进程将被终止。

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class WindowsProcess
{
    private String processName;

    public WindowsProcess(String processName)
    {
        this.processName = processName;
    }

    public void kill() throws Exception
    {
        if (isRunning())
        {
            getRuntime().exec("taskkill /F /IM " + processName);
        }
    }

    private boolean isRunning() throws Exception
    {
        Process listTasksProcess = getRuntime().exec("tasklist");
        BufferedReader tasksListReader = new BufferedReader(
                new InputStreamReader(listTasksProcess.getInputStream()));

        String tasksLine;

        while ((tasksLine = tasksListReader.readLine()) != null)
        {
            if (tasksLine.contains(processName))
            {
                return true;
            }
        }

        return false;
    }

    private Runtime getRuntime()
    {
        return Runtime.getRuntime();
    }
}
