总结:要实现定时器quartz,我们注意两步就行了,一是写好实现类注意实现类的方法名要和配置中一致,二是做好配置。然后就可以测试了。
①定时器实现类
HealthRecodersTokenScheduler.java
public class HealthRecodersTokenScheduler {public void execute() throws Exception {
System.err.println("=========定时去获取tokenId,tokenId的时效是30分钟有效========:");
}
②定时器配置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.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsdhttp://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" /><!-- 是否允许任务并发执行。当值为false时,表示必须等到前一个线程处理完毕后才再启一个新的线程 --><property name="concurrent" value="false" /></bean><!-- Scheduler --><bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"><property name="triggers"><list><ref bean="simpleTrigger" /></list></property></bean><!-- 启动后40秒执行一次,后面每隔25分钟执行一次,repeatCount 是执行的次数,-1代表永久,0代表不执行,1代表执行一次 --><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中引入配置的定时器xml
ApplicationContext.xml
<import resource="classpath:scheduler/healthrecoders_token-scheduler.xml"/>
注意我们引入的依赖为:
(要注意其他地方是否也包含了quartz,因为有可能会冲突)
<!-- 定时器quertz --><dependency><groupId>org.quartz-scheduler</groupId><artifactId>quartz</artifactId><version>2.2.0</version></dependency>
