java命令执行jar包(里面的main函数,无web.xml文件)的方式（包括依赖其它的jar包）,使用Google-Guava Concurrent包里的Service框架,maven工程

本文详细介绍了如何使用Maven的shade插件来配置pom.xml文件，从而实现将Java应用程序打包为一个可直接运行的Jar包。此外，还展示了如何通过指定main-class属性来设置程序的入口，并给出了具体的Java代码示例。

pom.xml中的配置

大家都知道一个java应用项目可以打包成一个jar，当然你必须指定一个拥有main函数的main class作为你这个jar包的程序入口。

java代码

import java.io.FileNotFoundException;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.util.Log4jConfigurer;

import com.google.common.util.concurrent.AbstractIdleService;

public class Bootstrap extends AbstractIdleService {
	private static Logger log = LoggerFactory.getLogger(Bootstrap.class);
    private ClassPathXmlApplicationContext context;
    
    static {
		try {
			Log4jConfigurer.initLogging("classpath:conf/log4j.properties");
		} catch (FileNotFoundException ex) {
			System.err.println("Cannot Initialize log4j");
		}
	}
    
    public static void main(String[] args) {
        Bootstrap bootstrap = new Bootstrap();
        bootstrap.startAsync();
        try {
            Object lock = new Object();
            synchronized (lock) {
                while (true) {
                    lock.wait();
                }
            }
        } catch (InterruptedException ex) {
            log.error("ignore interruption");
        }
    }

    @Override
    protected void startUp() throws Exception {
        context = new ClassPathXmlApplicationContext(new String[]{"spring/spring.xml"});
        context.start();
        context.registerShutdownHook();
        log.info(" service started successfully!");
    }

    @Override
    protected void shutDown() throws Exception {
        context.stop();
        log.info(" service stop successfully!");
    }
}

用maven打包后,部署发布,执行java -jar 项目名.jar命令,启动jar包
