本文内容纲要：spring Quartz基于配置文件和注解的实现

这里仅仅是做简单的记录怎样实现。

一、基于配置文件的实现

①编写须要调度的类

package com.study;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
//@Component
public class QuartzJob {
	public QuartzJob(){
		System.out.println("Quartzjob创建成功");
	}
	//@Scheduled(cron = "0/1 * *  * * ? ")
	public void run(){
		System.out.println("Quartz运行的任务调度");
	}
}

注：里面的注解是后面的是注解的实现中用到的

②设置配置文件spring-quartz.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
	<bean id="quartzJob" class="com.study.QuartzJob"></bean>
	<!-- 定义调用对象和调用对象的方法 -->
	<bean id="jobtask"
		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<!-- 调用的类 -->
		<property name="targetObject">
			<ref bean="quartzJob" />
		</property>
		<!-- 调用类中的方法 -->
		<property name="targetMethod">
			<value>run</value>
		</property>
	</bean>
	<!-- 定义触发时间 -->
	<bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<ref bean="jobtask" />
		</property>
		<!-- cron表达式 -->
		<property name="cronExpression">
			<!--<value>10,15,20,25,30,35,40,45,50,55 * * * * ?</value>-->
			<value>0/1  * * * * ?</value>
		</property>
	</bean>
	<!-- 总管理类 假设将lazy-init='false'那么容器启动就会运行调度程序  -->
	<bean id="startQuertz" lazy-init="false" autowire="no"
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="doTime" />
			</list>
		</property>
	</bean>
</beans>

注意cron表达式，这里配置的是每隔1s运行。

③启动spring容器

package com.study;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
	public static void main(String[] args) {
		System.out.println("启动spring容器");
		ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring-quartz.xml");
	}
}

二、基于注解的实现

①配置须要调度的类，并加入注解

package com.study;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class QuartzJob {
	public QuartzJob(){
		System.out.println("Quartzjob创建成功");
	}
	@Scheduled(cron = "0/1 * *  * * ? ")
	public void run(){
		System.out.println("Quartz运行的任务调度");
	}
}

②加入配置文件

<?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:task="http://www.springframework.org/schema/task"
	xsi:schemaLocation="http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   
    http://www.springframework.org/schema/context   
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
    http://www.springframework.org/schema/task 
    http://www.springframework.org/schema/task/spring-task-3.0.xsd  " >
    <task:annotation-driven/>  
    <context:component-scan base-package="com.study"/>
    <context:annotation-config/>
</beans>

③启动容器，这里通过配置web.xml启动

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-quartz2.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>
