我需要一种 Java 方法来找到一个正在运行的 Win 进程,我从中知道可执行文件的名称。我想看看它现在是否正在运行,如果我找到它,我需要一种方法来终止该进程。

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);

 }

例子:

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

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

 if (isProcessRunning(processName)) {

  killProcess(processName);
 }
}

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

有一个小 API 提供了所需的功能:

这是一种很时髦的做法:

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}")
}

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

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)。

使用java.lang.Runtime.exec执行程序。

使用以下类杀死 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();
    }
}

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,您可以尝试使用 JNA(Java Native Access)。https://jna.dev.java.net/

Super kakes 写的答案的微小变化

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

变成 ..

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

/IMF选项不起作用.它不会杀死记事本..而/IM选项实际上有效
