使用按钮启动/停止 Windows 服务

Question

我正在创建一个非常简单的应用程序来停止和启动 Windows 服务。我需要它有一个GUI界面，所以我选择了JAVA。如果您知道更简单的语言，请告诉我。作为一个示例，我希望它停止并启动打印后台处理程序。我已经使用 NetBeans 创建了 GUI 界面，但我需要有关编码部分的帮助。请帮忙。谢谢！

package MyServiceToolPKG;
public class MyServiceToolGUI extends javax.swing.JFrame {

/**

public MyServiceToolGUI() {
    initComponents();

更新代码：

    // TODO add your handling code here:
    StartSpooler();
}                                           

private void StopButtonActionPerformed(java.awt.event.ActionEvent evt) {                                           
    // TODO add your handling code here:
    StopSpooler();
}
private void StopSpooler() {
    String[] args = {"stop"};
    String[] command = {"cmd.exe", "/c", "sc", args[0], "spooler"};
    try {
      Process process = new ProcessBuilder(command).start();
      InputStream inputStream = process.getInputStream();
      InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
      BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
      String line;
      while ((line = bufferedReader.readLine()) != null) {
         System.out.println(line);
      }
    } catch(Exception ex) {

    }
}

      }
    } catch(Exception ex) {
      System.out.println("Exception : "+ex);
    }
}

谢谢大家！

这是我的代码：

private void StopSpooler() {
    String[] args = {"stop"};
    String[] command = {"cmd.exe", "/c", "sc", args[0], "spooler"};
    try {
      Process process = new ProcessBuilder(command).start();
      InputStream inputStream = process.getInputStream();
      InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
      BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
      String line;
      while ((line = bufferedReader.readLine()) != null) {
         System.out.println(line);
      }
    } catch(Exception ex) {
      System.out.println("Exception : "+ex);
    }
}

private void StartSpooler() {
    String[] args = {"start"};
    String[] command = {"cmd.exe", "/c", "sc", args[0], "spooler"};
    try {
      Process process = new ProcessBuilder(command).start();
      InputStream inputStream = process.getInputStream();
      InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
      BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
      String line;
      while ((line = bufferedReader.readLine()) != null) {
         System.out.println(line);
      }
    } catch(Exception ex) {
      System.out.println("Exception : "+ex);
    }
}

我创建了一个批处理文件，我以管理员身份运行并调用 jar 应用程序

@echo off
java.exe -jar C:\test\MyServiceTool.jar
pause

在 Windows 命令行中： 您需要管理员权限才能执行此操作。 停止 Windows 服务：

net stop Spooler

要启动 Windows 服务：

net start Spooler

在 Java 中，您可以使用以下命令执行 dos 命令：

try {
        Runtime.getRuntime().exec("net stop spooler");
    } catch (IOException ex) {
        JOptionPane.showMessageDialog(null, ex.getMessage());
    }
