我正在尝试将一个简单的 java 应用程序作为 Windows 服务运行。这是我的主要类文件。我正在尝试每五秒钟打印一次时间，并在一分钟后停止。包名称是 samPack。

package samPack;
import java.util.Date;


public class Time {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Thread thread = new Thread()
        {

            public void run()
            {
                long start = System.currentTimeMillis();
                long end = start + 60*1000;


                    while (System.currentTimeMillis() < end){
                        //System.out.println("Hello World");
                        Date date = new Date();
                        System.out.println("Ram Test   ---- >  "+date.toString());

                        try
                        {
                            Thread.sleep(5000); // 1 second
                        } catch (Exception e)
                        {
                            e.printStackTrace();
                        }
                    }

            }
        };
        thread.start();

    }

}

为了使其成为 Windows 服务，我下载了 Tanuki Software 的 Java Service Wrapper。并解压桌面上的文件夹。我为上述代码创建了一个可运行的 jar 文件，并将其粘贴到 Java 服务 Wrapper 的 bin 文件夹和 lib 文件夹中。bin 文件夹中的 DemoApp.bat 失败我已将其更改为 run.bat，然后在该文件中我已将变量 WRAPPER_CONF_DEFAULT 更改为 ../conf/wrapper.conf。

在 Wrapper.conf 文件中，这些是我所做的更改

# Java Main class. This class must implement the WrapperListener interface
# or guarantee that the WrapperManager class is initialized. Helper
# classes are provided to do this for you. See the Integration section
# of the documentation for details.
wrapper.java.mainclass=samPack.Time

# Java Classpath (include wrapper.jar) Add class path elements as
wrapper.java.classpath.1=../lib/wrappertest.jar
    wrapper.java.classpath.2=../lib/wrapper.jar
    wrapper.java.classpath.3=../lib/sam.jar

# Name of the service
wrapper.name=samtestservice

# Display name of the service
wrapper.displayname=Sam Test Service

# Description of the service
wrapper.description=Sam Test Service Decs

# Mode in which the service is installed. AUTO_START, DELAY_START or DEMAND_START
wrapper.ntservice.starttype=AUTO_START

现在，当我运行 bat 文件 run.bat 时，它正在控制台中运行并显示以下结果。

wrapper  | Startup failed: Timed out waiting for a signal from the JVM.

wrapper  | ------------------------------------------------------------------------
wrapper  | Advice:
wrapper  | The Wrapper consists of a native component as well as a set of classes
wrapper  | which run within the JVM that it launches.  The Java component of the
wrapper  | Wrapper must be initialized promptly after the JVM is launched or the
wrapper  | Wrapper will timeout, as just happened.  Most likely the main class
wrapper  | specified in the Wrapper configuration file is not correctly initializing
wrapper  | the Wrapper classes:
wrapper  |     samPack.Time
wrapper  | While it is possible to do so manually, the Wrapper ships with helper
wrapper  | classes to make this initialization processes automatic.
wrapper  | Please review the integration section of the Wrapper's documentation
wrapper  | for the various methods which can be employed to launch an application
wrapper  | within the Wrapper:

我已经通过运行 bat 文件安装了该服务，但无法启动该服务。服务开始。怎么了？

修改wrapper.java.mainclass=samPack.Time为wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp

并添加一个新行wrapper.app.parameter.1=samPack.Time
