java判断线程是否被中断 java判断进程是否存在

以nginx进程为例子

private final static String NAME_STRING = "nginx.exe";
//传入进程名称processName
public static boolean findProcess() {
BufferedReader bufferedReader = null;
try {
Process proc = Runtime.getRuntime().exec("tasklist -fi " + ‘"‘ + "imagename eq " + NAME_STRING +‘"‘);
bufferedReader = new BufferedReader(new InputStreamReader(proc.getInputStream()));
String line = null;
while ((line = bufferedReader.readLine()) != null) {
if (line.contains(NAME_STRING)) {
return true;
}
}
return false;
} catch (Exception ex) {
ex.printStackTrace();
return false;
} finally {
if (bufferedReader != null) {
try {
bufferedReader.close();
} catch (Exception ex) {}
}
}
}
