我需要一种Java方法来查找正在运行的Win进程,我知道可执行文件的名称。我想看看它是否正在运行,如果我发现它,我需要一种方法来终止它。

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);

 }

实施例

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()从Java调用它们。

有一个提供所需功能的API:

您可以使用命令行工具来终止SysInternals PsKillSysInternals PsList等过程。

您也可以使用内置tasklist.exe和taskkill.exe,但这些只能在Windows XP Professional及更高版本(不在家庭版中)上使用。

使用java.lang.Runtime.exec执行程序。

这是一种时髦的方式:

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}")
}

将以下课程用于kill a Windows processif it is running)。我使用force命令行参数/F来确保/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();
    }
}

你必须调用一些本机代码,因为恕我直言,没有库可以做到这一点。由于JNI很麻烦,你可能会尝试使用JNA(Java Native Access)。 https://jna.dev.java.net/

Super kakes写的答案变化很小

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

已更改为..

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
