quartz定時器實現

quartz


總結:要實現定時器quartz,我們註意兩步就行了,一是寫好實現類註意實現類的方法名要和配置中一致,二是做好配置。然後就可以測試了。


①定時器實現類

HealthRecodersTokenScheduler.java

public class HealthRecodersTokenScheduler {
	public void execute() throws Exception {
		 System.err.println("=========定時去獲取tokenId,tokenId的時效是30分鐘有效========:");
	}


②定時器配置xml

healthrecoders_token-scheduler.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:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="
	http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
	http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd">

	<!-- quartz -->
	<bean id="healthTokenScheduler" class="com.kentrasoft.entity.healthrecodes.HealthRecodersTokenScheduler">
	</bean>
	<!-- JobDetail -->
	<bean id="getTokenDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject" ref="healthTokenScheduler" />
		<property name="targetMethod" value="execute" />
		<!-- 是否允許任務並發執行。當值為false時,表示必須等到前一個線程處理完畢後才再啟一個新的線程 -->
		<property name="concurrent" value="false" />
	</bean>

	<!-- Scheduler -->
	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="simpleTrigger" />
			</list>
		</property>
	</bean>

	<!-- 啟動後40秒執行一次,後面每隔25分鐘執行一次,
	repeatCount 是執行的次數,-1代表永久,0代表不執行,1代表執行一次
	 -->
	<bean id="simpleTrigger"
		class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
		<property name="jobDetail" ref="getTokenDetail" />
		<property name="startDelay">
			<value>40000</value>
		</property>
		<property name="repeatInterval">
			<value>1500000</value>
		</property>
		<property name="repeatCount">
			<value>-1</value>
		</property>
	</bean>

</beans>


③在ApplicationContext.xml中引入配置的定時器xml

ApplicationContext.xml

<import resource="classpath:scheduler/healthrecoders_token-scheduler.xml"/>

註意我們引入的依賴為:

(要註意其他地方是否也包含了quartz,因為有可能會沖突)

        <!-- 定時器quertz -->
	<dependency>
		<groupId>org.quartz-scheduler</groupId>
		<artifactId>quartz</artifactId>
		<version>2.2.0</version>
	</dependency>
