spring 4.1.7

jdk1.8

1.時間設定在javaBean的@註解裡

spring-task.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:task="http://www.springframework.org/schema/task"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx.xsd
	http://www.springframework.org/schema/task  
	http://www.springframework.org/schema/task/spring-task-3.1.xsd"
	 default-lazy-init="false">
	<!-- 定時器開關 -->
	<task:annotation-driven />
	<!-- 掃描mytask包下的檔案 -->
	<context:component-scan base-package="com.test.mytask" /> 
	
</beans>
 

javaBean:

package com.test.mytask;

import java.util.List;

@Component("test")
public class Test{
	
	@Scheduled(cron = "*/5 * * * * ?")
	public void testMethod(){
		System.out.println("每5秒顯示一次,"+new Date());

    }

--------------------------------------------------------------------------

2.時間設定在spring-task.xml裡

spring-task:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:task="http://www.springframework.org/schema/task"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx.xsd
	http://www.springframework.org/schema/task  
	http://www.springframework.org/schema/task/spring-task-3.1.xsd"
	 default-lazy-init="false">
	<!-- 此處和另一個方法用到註解不一樣，不必有driver-->
	<context:annotation-config />  
	<!-- 掃描mytask包下的檔案 -->
	<context:component-scan base-package="com.test.mytask" /> 
	
	<bean id="Test" class="com.test.mytask.Test" />
	<task:scheduled-tasks>    
     <task:scheduled ref="Test" method="testMethos" cron="*/5 * * * * ?" />     
	</task:scheduled-tasks>  
</beans>
 

javaBean:

package com.test.mytask;

import java.util.Date;

@Component("Test")
public class Test{
	
	@Scheduled
	public void testMethod(){
		System.out.println("每5秒顯示一次,"+new Date());
	}
}

比較：

    在@scheduled註解中寫時間設定，不用太多的配置xml ；

    但是在xml配置檔案中寫時間設定方便別人修改和管理，建議採用xml中設定時間的方法
