通过 Daemon 作为独立运行 spring

Question

我正在尝试通过 Daemon 服务作为独立应用程序运行 Spring。

我已经配置了 run.sh 脚本并添加了所有 Spring jars 框架。

现在我正在尝试以这种方式从守护程序类执行我的起点类：

代码： 公共类 FeedDaemon 实现守护进程 { 公共 FeedDaemon() { }

protected final static Logger log = LoggerFactory.getLogger(FeedDaemon.class);
protected boolean shouldBeRunning = false;
protected ProviderFactory runner = null;

@Override
public void destroy()
{
    runner = null;
}

@Override
public void init(DaemonContext arg0) throws Exception
{
    runner = new ProviderFactory();
}

public void start() throws RuntimeError, ConfigError
{
    log.info("Starting daemon");
    runner.start();
}

public void stop() throws Exception
{
    log.info("Starting Shutting daemon ...");
    runner.stop();
}

}

代码：

package com.spring.test;

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.spring.aspect.Spring3HelloWorld;
import com.spring.beans.ParkingCar.CarBean;
import com.spring.beans.ParkingCar.CarMaker;
import com.spring.beans.ParkingCar.FourWheelsVechile;
import com.spring.beans.ParkingCar.TwoWheelsVechile;
import com.spring.beans.ParkingCar.Vechile;
import com.spring.beans.ParkingCar.VechileDetails;
import com.spring.beans.calculator.CalculateNumbersHolderBean;
import com.spring.beans.calculator.CalculateStrategyBean;
import com.spring.beans.calculator.CalculatorBean;

public class Spring3HelloWorldTest
{

    static Logger logger = Logger.getLogger(Spring3HelloWorldTest.class);

    public static void execute()
    {
        try
        {   
            ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
            logger.debug("3");


            Vechile fourWheelsVechile = (FourWheelsVechile) context.getBean("Ambulance");
            fourWheelsVechile.drive();
            CarMaker carMaker = (CarMaker) context.getBean("carMaker");
            CarBean carBean = carMaker.createNewCar();
            carBean.driveCar();
        }
        catch (Throwable e)
        {
            logger.error(e);
        }

    }
}

我得到这个错误：

这是我的 run.sh 脚本：

有什么想法吗？

谢谢， 射线。

Answer 1

您似乎已经添加了所有包含 Spring java 源代码（未编译代码）的 jar。您应该改为将未命名为 ...-sources... 的 jar 添加到类路径中。

Answer 2

spring jars 不在类路径中。检查我的answer。通过命令行在类路径中添加所有库（当然在你的 shell 脚本中）。

好吧，我现在看到了您的问题。您在类路径中有源文件。这些被称为org.springframework.web.servlet-sources-3.1.1.RELEASE.jar，而编译的jar被称为org.springframework.web.servlet-3.1.1.RELEASE.jar
