java 检查进程是否存在

以nginx进程为例子

 

private final static String NAME_STRING = "nginx.exe";//传入进程名称processNamepublic 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) {}}}}
