情况如下:

我被要求使用 InstallAnywhere 8,这是一种基于 Java 的安装程序 IDE,它允许启动和停止 Windows 服务,但没有内置方法来查询它们的状态。幸运的是,它允许您在 Java 中创建可以在安装过程中随时调用的自定义操作(通过我认为是相当复杂的 API)。

我只需要一些可以告诉我特定服务是启动还是停止的东西。

IDE 还允许调用批处理脚本,所以这也是一个选项,虽然一旦脚本运行,几乎没有办法验证它是否成功,所以我试图避免这种情况。

欢迎任何建议或批评。

这就是我必须做的。它很丑陋,但效果很好。

String STATE_PREFIX = "STATE              : ";

String s = runProcess("sc query \""+serviceName+"\"");
// check that the temp string contains the status prefix
int ix = s.indexOf(STATE_PREFIX);
if (ix >= 0) {
  // compare status number to one of the states
  String stateStr = s.substring(ix+STATE_PREFIX.length(), ix+STATE_PREFIX.length() + 1);
  int state = Integer.parseInt(stateStr);
  switch(state) {
    case (1): // service stopped
      break;
    case (4): // service started
      break;
   }
}

runProcess是一个私有方法,它将给定的字符串作为命令行进程运行并返回结果输出。正如我所说,丑陋,但有效。希望这可以帮助。

您可以即时创建一个小型 VBS,启动它并捕获它的返回码。

import java.io.File;
import java.io.FileWriter;

public class VBSUtils {
  private VBSUtils() {  }

  public static boolean isServiceRunning(String serviceName) {
    try {
        File file = File.createTempFile("realhowto",".vbs");
        file.deleteOnExit();
        FileWriter fw = new java.io.FileWriter(file);

        String vbs = "Set sh = CreateObject(\"Shell.Application\") \n"
                   + "If sh.IsServiceRunning(\""+ serviceName +"\") Then \n"
                   + "   wscript.Quit(1) \n"
                   + "End If \n"
                   + "wscript.Quit(0) \n";
        fw.write(vbs);
        fw.close();
        Process p = Runtime.getRuntime().exec("wscript " + file.getPath());
        p.waitFor();
        return (p.exitValue() == 1);
    }
    catch(Exception e){
        e.printStackTrace();
    }
    return false;
  }


  public static void main(String[] args){
    //
    // DEMO
    //
    String result = "";
    msgBox("Check if service 'Themes' is running (should be yes)");
    result = isServiceRunning("Themes") ? "" : " NOT ";
    msgBox("service 'Themes' is " + result + " running ");

    msgBox("Check if service 'foo' is running (should be no)");
    result = isServiceRunning("foo") ? "" : " NOT ";
    msgBox("service 'foo' is " + result + " running ");
  }

  public static void msgBox(String msg) {
    javax.swing.JOptionPane.showConfirmDialog((java.awt.Component)
       null, msg, "VBSUtils", javax.swing.JOptionPane.DEFAULT_OPTION);
  }
}

根据其他答案,我构建了以下代码来检查 Windows 服务状态:

public void checkService() {
  String serviceName = "myService";  

  try {
    Process process = new ProcessBuilder("C:\\Windows\\System32\\sc.exe", "query" , serviceName ).start();
    InputStream is = process.getInputStream();
    InputStreamReader isr = new InputStreamReader(is);
    BufferedReader br = new BufferedReader(isr);

    String line;
    String scOutput = "";

    // Append the buffer lines into one string
    while ((line = br.readLine()) != null) {
        scOutput +=  line + "\n" ;
    }

    if (scOutput.contains("STATE")) {
        if (scOutput.contains("RUNNING")) {
            System.out.println("Service running");
        } else {
            System.out.println("Service stopped");
        }       
    } else {
        System.out.println("Unknown service");
    }
  } catch (IOException e) {
    e.printStackTrace();
  } 
}

我多年来一直在与安装程序打交道,诀窍是创建自己的 EXE 并在安装时调用它。这提供了很好的灵活性,例如在发生错误时显示精确的错误消息,并具有基于成功的返回值,以便您的安装程序知道发生了什么。

下面介绍如何启动、停止和查询 Windows 服务 (C++) 的状态:http: //msdn.microsoft.com/en-us/library/ms684941 (VS.85).aspx (VB 和 C# 提供类似的功能)

过去我在 Java Service Wrapper 上遇到过一些运气。根据您的情况,您可能需要付费才能使用它。但它提供了一个干净的解决方案,支持 Java 并且可以在 InstallAnywhere 环境中使用(我认为)没有什么麻烦。这也将允许您在 Unix 机器上支持服务。

在黑暗中拍摄,但请查看您的 Install Anywhere java 文档。

具体来说,

/javadoc/com/installshield/wizard/platform/win32/Win32Service.html

班上:

com.installshield.wizard.platform.win32
Interface Win32Service

All Superinterfaces:
    Service 

方法:

public NTServiceStatus queryNTServiceStatus(String name)
                                     throws ServiceException

    Calls the Win32 QueryServiceStatus to retrieve the status of the specified service. See the Win32 documentation for this API for more information.

    Parameters:
        name - The internal name of the service. 
    Throws:
        ServiceException

我对给定的解决方案进行了即兴创作,使其独立于语言环境。正如Alejandro González 正确指出的那样,比较字符串“RUNNING”在非英语语言环境的系统中不起作用。

我使用了sc interrogate并查找它返回的状态码。

主要是,服务可以有 3 种状态:-

1 - 不可用

[SC] OpenService FAILED 1060: The specified service does not exist as an installed service.

2 - 不运行

([SC] ControlService FAILED 1062: The service has not been started)

3 - 跑步

    TYPE               : 10  WIN32_OWN_PROCESS
    STATE              : 2  START_PENDING
                            (NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
    WIN32_EXIT_CODE    : 0  (0x0)
    SERVICE_EXIT_CODE  : 0  (0x0)
    CHECKPOINT         : 0x0
    WAIT_HINT          : 0x7d0
    PID                : 21100code here

所以在下面的代码中使用它们,给了我们想要的结果:-

public static void checkBackgroundService(String serviceName) {
    Process process;
    try {
        process = Runtime.getRuntime().exec("sc interrogate " + serviceName);
        Scanner reader = new Scanner(process.getInputStream(), "UTF-8");
        StringBuffer buffer = new StringBuffer();
        while (reader.hasNextLine()) {
            buffer.append(reader.nextLine());
        }
        System.out.println(buffer.toString());
            if (buffer.toString().contains("1060:")) {
                System.out.println("Specified Service does not exist");
            } else if (buffer.toString().contains("1062:")) {
                System.out.println("Specified Service is not started (not running)");
            } else {
                System.out.println("Specified Service is running");
            }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

在启动期间,使用File.deleteOnExit()创建一个文件。

检查脚本中是否存在该文件。

只需调用此方法即可检查服务的状态是否正在运行。

public boolean checkIfServiceRunning(String serviceName) {
    Process process;
    try {
      process = Runtime.getRuntime().exec("sc query " + serviceName);
      Scanner reader = new Scanner(process.getInputStream(), "UTF-8");
      while(reader.hasNextLine()) {
         if(reader.nextLine().contains("RUNNING")) {
           return true;
         }
      }
     } catch (IOException e) {
         e.printStackTrace();
     }            
     return false;
}
