本文介绍了一种使用Java代码管理本地进程的方法，包括获取特定端口的进程ID、根据进程ID获取映像名称以及根据映像名称关闭进程的详细步骤。通过运行一系列系统命令，这些方法能够帮助开发者有效地监控和控制运行中的进程。
public class TestPort
{
public static void main(String[] args)
{
System.out.println(getPID("3306"));//得到进程ID,3306是端口名称
System.out.println(getProgramName(getPID("3306")));//根据进程ID得到映像名称
killTask(getProgramName(getPID("3306")));//根据映像名称关闭进程
}
// 得到进程ID
public static String getPID(String port){
InputStream is = null;
BufferedReader br = null;
String pid = null;
try
{
String[] args = new String[]{"cmd.exe","/c","netstat -aon|findstr",port};
is = Runtime.getRuntime().exec(args).getInputStream();
br = new BufferedReader(new InputStreamReader(is));
String temp = br.readLine();
if(temp != null){
String[] strs = temp.split("\\s");
pid=strs[strs.length-1];
}
}
catch (IOException e)
{
e.printStackTrace();
}finally{
try
{
br.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
return pid;
}
//根据进程ID得到映像名称
public static String getProgramName(String pid){
InputStream is = null;
BufferedReader br = null;
String programName = null;
try
{
String[] args = new String[]{"cmd.exe","/c","tasklist|findstr",pid};
is = Runtime.getRuntime().exec(args).getInputStream();
br = new BufferedReader(new InputStreamReader(is));
String temp = br.readLine();
if(temp != null){
String[] strs = temp.split("\\s");
programName=strs[0];
}
}
catch (IOException e)
{
e.printStackTrace();
}finally{
try
{
br.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
return programName;
}
//根据映像名称关闭进程
public static void killTask(String programName){
String[] args = new String[]{"Taskkill","/f","/IM",programName};
try
{
Runtime.getRuntime().exec(args);
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
