普通Java工程利用注解Spring做周期性任务调度框架搭建

需求：

利用注解Spring做周期任务执行操作，这样如果利用spring的task去操作那么会非常简单。

实现：

lib依赖：

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-core</artifactId>
	<version>3.2.0.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-context</artifactId>
	<version>3.2.0.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-beans</artifactId>
	<version>3.2.0.RELEASE</version>
</dependency>

spring配置文件：spring- collect.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:task="http://www.springframework.org/schema/task" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:beans="http://www.springframework.org/schema/beans" xmlns:device="http://www.springframework.org/schema/mobile/device"
	xsi:schemaLocation="
	http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.2.xsd
    http://www.springframework.org/schema/task   
    http://www.springframework.org/schema/task/spring-task-3.2.xsd  ">

	<context:component-scan base-package="org.apache.tools.collect" />
	<bean id="propertyConfigure"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" />
	<task:scheduled-tasks>
		<task:scheduled ref="preJob" method="run" cron="0 */1 * * * ?" />
	</task:scheduled-tasks>
</beans>

main方法加载部分：

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {
	private static ClassPathXmlApplicationContext context = null;

	public static ClassPathXmlApplicationContext getContextInstance() {
		if (context == null) {
			start();
		}
		if (!context.isRunning()) {
			App.context.refresh();
			context.registerShutdownHook();
		}
		return context;
	}

	private static void start() {
		context = new ClassPathXmlApplicationContext(
				"classpath:spring-collect.xml");
		context.registerShutdownHook();
	}

	public static void main(String[] args) {
		App.start();

	}
}

业务调度执行部分：

import org.springframework.stereotype.Service;

@Service("preJob")
public class PreJob {

	public void run() {
		System.out.println("task execute**********"+System.currentTimeMillis());
	}
}
