JAVA實現獲取Linux下進程PID並殺掉進程

話不多說,直接上代碼!

public class CloseLinuxProcess {
	public static void main(String[] args) {
		String PID = getPID("java -jar test.jar");
		closeLinuxProcess(PID);
	}




	
	/**
	 * 獲取Linux進程的PID
	 * @param command
	 * @return
	 */
	public static String getPID(String command){
		BufferedReader reader =null;
		try{
			//顯示所有進程
			Process process = Runtime.getRuntime().exec("ps -ef");
			reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
			String line = null;
			while((line = reader.readLine())!=null){
				if(line.contains(command)){
					System.out.println("相關信息 -> "+command);
					String[] strs = line.split("\s+");
					return strs[1];
				}
			}
		}catch(Exception e){
			e.printStackTrace();
		}finally{
			if(reader!=null){
				try {
					reader.close();
				} catch (IOException e) {
				}
			}
		}
		return null;
	}
	
	/**
	 * 關閉Linux進程
	 * @param Pid 進程的PID
	 */
	public static void closeLinuxProcess(String Pid){
		Process process = null;
		BufferedReader reader =null;
		try{




			//殺掉進程
			process = Runtime.getRuntime().exec("kill -9 "+Pid);
			reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
			String line = null;
			while((line = reader.readLine())!=null){
				System.out.println("kill PID return info -> "+line);
			}
		}catch(Exception e){
			e.printStackTrace();
		}finally{
			if(process!=null){
				process.destroy();
			}
			
			if(reader!=null){
				try {
					reader.close();
				} catch (IOException e) {
				}
			}
		}
	}
