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.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsdhttp://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());}
}
