1、编写基础服务类，实现Daemon init 、start 、stop
package com.allinfinance.yak.support.service;
import java.io.FileNotFoundException;
import java.util.Iterator;
import java.util.Map;
import org.apache.commons.daemon.Daemon;
import org.apache.commons.daemon.DaemonContext;
import org.apache.commons.daemon.DaemonInitException;
import org.apache.commons.lang.StringUtils;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.util.Log4jConfigurer;
import cn.webank.rmb.api.RMB;
import com.allinfinance.yak.support.future.TaskExecutor;
/**
* 基础的服务Daemon. 可以带一个参数，指定在classpath中加载的spring配置文件名，程序会自动加上 "-context.xml"后缀
*
* @author licj
*
*/
public class ServiceDaemon implements Daemon {
private ConfigurableApplicationContext ctx;
@Override
public void init(DaemonContext context) throws DaemonInitException,
Exception {
initLogging();
ctx = new ClassPathXmlApplicationContext(
getContextFilename(context.getArguments()));
ctx.registerShutdownHook();
}
private static void initLogging() throws FileNotFoundException {
//默认调用classpath下的log4j.properties，这样可以有效的避免因为xml优先的原因，被某些jar包里的log4j.xml给覆盖了。
//相当于主动调整默认配置文件加载优先级
String logLocation = System.getProperty("log.config");
if (StringUtils.isNotBlank(logLocation))
Log4jConfigurer.initLogging(logLocation, 1000 * 60);
else
Log4jConfigurer.initLogging("classpath:log4j.properties");
}
@Override
public void start() throws Exception {
}
@Override
public void stop() throws Exception {
RMB.stopWait();
//关闭所有的任务执行器
Map<String,TaskExecutor> taskExecutorMap=ctx.getBeansOfType(TaskExecutor.class);
if(null!=taskExecutorMap){
Iterator<TaskExecutor> taskExecutorIter=taskExecutorMap.values().iterator();
while(taskExecutorIter.hasNext()){
TaskExecutor taskExecutor=taskExecutorIter.next();
if(null==taskExecutor){
continue;
}
taskExecutor.shutdownWait();
}
}
}
@Override
public void destroy() {
ctx.close();
}
/**
* 这样可以直接跑，要关闭就杀掉进程
*
* @param args
* @throws FileNotFoundException
*/
public static void main(String[] args) throws FileNotFoundException {
initLogging();
@SuppressWarnings("resource")
ConfigurableApplicationContext ctx = new ClassPathXmlApplicationContext(
getContextFilename(args));
ctx.registerShutdownHook();
}
public static String getContextFilename(String args[]) {
String filename = "/service-context.xml";
if (args.length >= 1 )
filename = "/" + args[0] + "-context.xml";
return filename;
}
protected ConfigurableApplicationContext getCtx() {
return ctx;
}
}
2、在debug/run configuration中配置启动，如图
