需要一種以編程方式檢查 Windows 服務狀態的方法

Question

這是情況：

我被要求使用 InstallAnywhere 8，這是一個基於 Java 的安裝程序 IDE，它允許啟動和停止 Windows 服務，但沒有內置方法來查詢它們的狀態。 幸運的是，它允許您在 Java 中創建可以在安裝過程中隨時調用的自定義操作（通過我認為是相當復雜的 API）。

我只需要一些可以告訴我特定服務是啟動還是停止的信息。

IDE 還允許調用批處理腳本，因此這也是一個選項，盡管腳本運行后，幾乎無法驗證它是否成功，因此我試圖避免這種情況。

歡迎任何建議或批評。

Answer 1

這就是我必須做的。 它很丑，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是一個私有方法，它將給定的字符串作為命令行進程運行並返回結果輸出。 正如我所說，丑陋，但有效。 希望這可以幫助。

您可以即時創建一個小型 VBS，啟動它並捕獲其返回代碼。

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);
  }
}

根據其他答案，我構建了以下代碼來檢查 Windows 服務狀態：

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();
  } 
}

Answer 4

我多年來一直與安裝程序打交道，訣竅是創建自己的 EXE 並在安裝時調用它。 這提供了良好的靈活性，例如在發生錯誤時顯示精確的錯誤消息，並具有基於成功的返回值，以便您的安裝人員知道發生了什么。

以下是如何啟動、停止和查詢 windows 服務 (C++) 的狀態： http : //msdn.microsoft.com/en-us/library/ms684941 (VS.85) .aspx （VB 和 C# 提供類似功能）

Answer 5

過去我在 Java Service Wrapper 上有過一些運氣。 根據您的情況，您可能需要付費才能使用它。 但它提供了一個干凈的解決方案，支持 Java 並且可以在 InstallAnywhere 環境中使用（我認為）沒有什么麻煩。 這也將允許您支持 Unix 機器上的服務。

Answer 6

在黑暗中拍攝，但請查看您的 Install Anywhere java 文檔。

具體來說，

/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

Answer 7

這是一個嚴格的 C#/P/Invoke 解決方案。

        /// <summary>
    /// Returns true if the specified service is running, or false if it is not present or not running.
    /// </summary>
    /// <param name="serviceName">Name of the service to check.</param>
    /// <returns>Returns true if the specified service is running, or false if it is not present or not running.</returns>
    static bool IsServiceRunning(string serviceName)
    {
        bool rVal = false;
        try
        {
            IntPtr smHandle = NativeMethods.OpenSCManager(null, null, NativeMethods.ServiceAccess.ENUMERATE_SERVICE);
            if (smHandle != IntPtr.Zero)
            {
                IntPtr svHandle = NativeMethods.OpenService(smHandle, serviceName, NativeMethods.ServiceAccess.ENUMERATE_SERVICE);
                if (svHandle != IntPtr.Zero)
                {
                    NativeMethods.SERVICE_STATUS servStat = new NativeMethods.SERVICE_STATUS();
                    if (NativeMethods.QueryServiceStatus(svHandle, servStat))
                    {
                        rVal = servStat.dwCurrentState == NativeMethods.ServiceState.Running;
                    }
                    NativeMethods.CloseServiceHandle(svHandle);
                }
                NativeMethods.CloseServiceHandle(smHandle);
            }
        }
        catch (System.Exception )
        {

        }
        return rVal;
    }

Answer 8

在啟動期間，使用File.deleteOnExit()創建一個文件。

檢查腳本中是否存在該文件。

Answer 9

只需調用此方法即可檢查服務的狀態是否正在運行。

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;
}

Answer 10

我即興創作了給定的解決方案，使其獨立於語言環境。 正如亞歷杭德羅·岡薩雷斯 (Alejandro González) 正確指出的那樣，比較字符串“RUNNING”在非英語語言環境的系統中不起作用。

我使用sc 詢問並查找它返回的狀態代碼。

主要是，該服務可以有 3 個狀態：-

1 - 不可用

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

2 - 不運行

([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

所以在下面的代碼中使用它們，給了我們想要的結果：-

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();
    }
}

希望這對某人有所幫助:)
