关于Windows：如何在Java中查找并杀死正在运行的Win-Processes？

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

我需要一种Java方式来查找正在运行的Win进程，从该进程我知道可执行文件的名称。我想看看它现在是否正在运行，如果找到了，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);

}

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tasklist和taskkill，并使用Runtime.exec()从Java调用它们。

这是一种常规的方法：

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}")
}

有一些API提供所需的功能：

Windows进程库

您可以使用命令行工具杀死SysInternals PsKill和SysInternals PsList之类的进程。

您也可以使用内置的tasklist.exe和taskkill.exe，但是它们仅在Windows XP Professional和更高版本(而不是家庭版)中可用。

使用java.lang.Runtime.exec执行程序。

使用以下类杀死Windows进程(如果正在运行)。我正在使用force命令行参数/F确保由/IM参数指定的进程将终止。
