我使用教程http://web.archive.org/web/20090228071059/http://blog.platinumsolutions.com/node/234
创建了一项服务我创建了如下文件:
C:\MyService1
\bin
\myService1.exe
\myService1w.exe
\classes
\com\services\MyService1.class
\HelloWorld.jar
\logs
现在,当我执行myService1.exe时,服务还没有开始。 我在日志中收到消息
[2015-06-02 15:23:29] [info] [ 3968] Commons Daemon procrun (1.0.15.0 32-bit) started

在我的stderror文件中,报告了以下内容:
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%\jre\lib;
JAVA_HOME: C:\Program Files\Java\jdk1.7.0;
Path: %JAVA_HOME%\bin;
当我查看事件查看器时,我得到:
MyService1服务因服务特定错误而终止系统无法打开文件。
我经常搜索服务程序应该包含哪些但没有运气。
答案 0 :(得分:3)
我最近在使用procrun将spring boot应用程序作为服务运行时遇到了同样的问题。
我的错误是我将主要课程的路径作为启动课程。当我使用org.springframework.boot.loader.JarLauncher
作为启动类时,这已得到解决。你应该用作启动类的类可以在
jar中的MANIFEST.MF
答案 1 :(得分:0)
我做了以下更改,以使我的服务成功运作。
文件夹结构:
C:\MyService1
\myService1.exe
\myService1w.exe
\MyService1.class
\HelloWorld.jar
\logs
Java Class(守护程序类):
以下是我班级的片段。
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");
}
