Spring的Task任务

转自：http://liuna718-163-com.iteye.com/blog/2215076

Spring Task提供两种方式进行配置，一种是annotation(标注)，而另外一种就是XML配置了。因为任务调度这样的需求，通常改动都是比较多的，如果用annotation的方式的话，改动就变得麻烦了，必须去重新编译。所以，我只是选择用XML配置的方式。

1.XML方式

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:task="http://www.springframework.org/schema/task"
 4     xsi:schemaLocation="
 5           http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
 6           http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd">
 7 
 8     <bean id="reminderProcessor" class="com.foo.task.ReminderProcessor">
 9         <property name="workers">
10             <array value-type="com.foo.task.Worker">
11                 <ref bean="projectScheduleRemindWorker" />
12             </array>
13         </property>
14     </bean>
15 
16     <!-- 配置任务线性池 -->
17      <task:executor id="executor" pool-size="3" />
18     <task:scheduler id="scheduler" pool-size="3" />
19     <!-- 启用annotation方式 -->
20     <task:annotation-driven scheduler="scheduler"
21         executor="executor" proxy-target-class="true" />
22 
23     <task:scheduled-tasks scheduler="scheduler">
24         <task:scheduled ref="reminderProcessor" method="process"
25             cron="0 0 12 * * ?" />
26     </task:scheduled-tasks>
27 </beans>

2.注解

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
 4     xmlns:context="http://www.springframework.org/schema/context"
 5     xmlns:sec="http://www.springframework.org/schema/security"
 6     xmlns:task="http://www.springframework.org/schema/task"
 7     xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
 8         http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd
 9         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
10         http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.1.xsd
11         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
12         http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.2.xsd
13         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"
14     xmlns:jpa="http://www.springframework.org/schema/data/jpa" xmlns:tx="http://www.springframework.org/schema/tx">
15     <!—spring扫描注解的配置   -->
16     <context:component-scan base-package="com.test.cache" />
17     <!-- 配置任务线性池 -->
18     <task:scheduler id="scheduler" pool-size="10" />
19     <task:executor id="executor" pool-size="10" />
20     <!—开启这个配置，spring才能识别@Scheduled注解   -->
21     <task:annotation-driven scheduler="scheduler" executor="executor" />
22 </beans>

java的类

 1 package com.test.cache;
 2 import org.springframework.scheduling.annotation.Scheduled;
 3 import org.springframework.stereotype.Component;
 4 
 5 @Component
 6 public class CrontabTask {
 7     
 8     @Scheduled(cron = "0 0/5 * * * *")
 9     public void autoBid() {
10         System.out.println("执行定时任务");
11     }
12     
13 }
