无法运行用户服务.异常:Failed to start Java, ServiceStart返回4

Question

我使用教程http://web.archive.org/web/20090228071059/http://blog.platinumsolutions.com/node/234创建了一个服务

我创建了如下文件:

C:MyService1
bin
    myService1.exe
    myService1w.exe
classes
    comservicesMyService1.class
    HelloWorld.jar
logs

现在当我执行myService1.exe时，服务没有启动。我得到下面的消息在我的日志

[2015-06-02 15:23:29] [info]  [ 3968] Commons Daemon procrun (1.0.15.0 32-bit) started

[2015-06-02 15:23:29] [info]  [ 3968] Commons Daemon procrun finished

在我的错误文件中，报告如下:

2015-06-02 15:23:29 Commons Daemon procrun stderr initialized

Exception in thread "main" 

我的环境变量如下:

 CLASSPATH: .;%JAVA_HOME%jrelib;
 JAVA_HOME: C:Program FilesJavajdk1.7.0;
 Path: %JAVA_HOME%bin;

当我检查事件查看器时，我得到:

MyService1服务终止，系统无法打开文件。

我搜索了很多服务程序应该包含的内容，但没有运气。

Answer 1

我最近在使用procrun将spring引导应用程序作为服务运行时遇到了同样的问题。我的错误是我把我的主类的路径作为启动类。当我使用org.springframework.boot.loader.JarLauncher作为启动类时，这得到了解决。应该用作启动类的类可以在清单。

Answer 2

为了使我的服务能够成功运行，我做了以下更改。

文件夹结构:

C:MyService1
    myService1.exe
    myService1w.exe
    MyService1.class
    HelloWorld.jar
    logs

Java Class (Daemon Class):

• 在默认包中创建java类
类有两个静态方法:start()和stop()
• start()应该有一个无限循环

下面是我的类的代码片段。

static boolean isRunning = true;
static boolean isJobsRunning = false;
@SuppressWarnings("static-access")
public static void start(String []args) {
    String command = "run.bat";
    System.out.println("Started JobServices successfully");
    while(isRunning){
        if(!isJobsRunning) { //the job should run only once after the service is started
            try {
                System.out.println("Running batch file");
                Runtime.getRuntime().exec(command);
                isJobsRunning = true;
                System.out.println("Executed batch file successfully");
            } catch (IOException e) {
                System.err.println("Unable to execute Jobs jar");
                e.printStackTrace();
            }
        }
    }
    System.out.println("Completed JobService");
}
public static void stop(String args[]) {
     if(!isRunning) 
         return;
     isRunning = false;
     System.out.println("JobService Stopped successfully");
}
