sping-task的运用
spring task，可以将它比作一个轻量级的Quartz，而且使用起来很简单，除spring相关的包外不需要额外的包，而且支持注解和配置文件两种形式，下面将分别介绍这两种方式。
一、搭建一个spring-web项目
（1）spingJOB.xml配置
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"

<task:annotation-driven executor="executor" scheduler="scheduler" />
<context:component-scan base-package="com.wei.dwx" />
beans>（2）springMvc.xml配置
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"

<property name="maxInMemorySize" value="4096" />
bean>
beans>（3）applicationContext.xml配置
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"

<context:component-scan base-package="com.wei.dwx" />
<import resource="springJOB.xml"/>
beans> （4）web.xml配置
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

project>二、使用注解形式
package com.wei.dwx;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class Task {
/**
* 每天上午5点15分触发（禁言调度）
*/
@Scheduled(cron="0/1 * * * * ?")
public void task(){
System.out.println("定时任务启动");
}
}三、使用配置文件方式
package com.wei.dwx;
import org.springframework.stereotype.Component;
@Component
public class TaskTwo {
public void job() {
System.out.println("定时任务启动----------------");
}
}修改springJOB.xml文件
