JAVA实现获取Linux下进程PID并杀掉进程

话不多说,直接上代码!

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

/**
* 获取Linux进程的PID
* @param command
* @return
*/
public static String getPID(String command){
BufferedReader reader =null;
try{
//显示所有进程
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("相关信息 -----> "+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;
}

/**
* 关闭Linux进程
* @param Pid 进程的PID
*/
public static void closeLinuxProcess(String Pid){
Process process = null;
BufferedReader reader =null;
try{
//杀掉进程
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) {

}
}
}
}
}
