on the following example you can find how can you check windws service status and you can parsed to do certain action
在以下示例中，您可以找到如何检查windws 服务状态，并且您可以解析以执行某些操作
import java.util.*;
import java.sql.*;
import java.io.*;
import java.text.*;
public class doscmd
{
public static void main(String args[])
{
try
{
Process p=Runtime.getRuntime().exec("sc query browser");
BufferedReader reader=new BufferedReader(new InputStreamReader(p.getInputStream()));
String line=reader.readLine();
while(line!=null)
{
if(line.trim().startsWith("STATE"))
{
if (line.trim().substring(line.trim().indexOf(":")+1,line.trim().indexOf(":")+4).trim().equals("1"))
System.out.println("Stopped");
else
if (line.trim().substring(line.trim().indexOf(":")+1,line.trim().indexOf(":")+4).trim().equals("2"))
System.out.println("Startting....");
else
if (line.trim().substring(line.trim().indexOf(":")+1,line.trim().indexOf(":")+4).trim().equals("3"))
System.out.println("Stopping....");
else
if (line.trim().substring(line.trim().indexOf(":")+1,line.trim().indexOf(":")+4).trim().equals("4"))
System.out.println("Running");
}
line=reader.readLine();
}
}
catch(IOException e1) { }

At the very least you should be able to launch a cmd.exe process with the command sc query service-nameand parse the output to determine the status. Not pretty, but lacking a Java API to the Windows service manager this would be a viable alternative.
至少您应该能够使用该命令启动 cmd.exe 进程sc query service-name并解析输出以确定状态。不漂亮，但缺少 Windows 服务管理器的 Java API，这将是一个可行的替代方案。
EDIT - Read the Javadoc for java.lang.ProcessBuilder, which will allow you to execute an external command. You should probably set the redirectErrorStreamproperty so that you don't have to handle two input streams (stdout and stderr), making for a much simpler design.
