Spring + quartz注解配置使用
本文接文spring4+quartz2基本配置及应用,使用注解配置
1、编写一个定时器执行类,重要的是使用Scheduled注解
AnnotationQueryJob.java
package com.hode.job;
import org.apache.log4j.Logger;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class AnnotationQueryJob {
private Logger log = Logger.getLogger(getClass());
@Scheduled(cron="0/1 * * * * ?")
public void execute(){
log.info("*** ok ***");
}
}
2、添加spring配置文件applicationContext-annotation.xml,其内容如下
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" 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:util="http://www.springframework.org/schema/util" xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd
http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd">
<context:component-scan base-package="com" />
<task:annotation-driven/>
</beans>
其中关键标签为<task:annotation-driven/>
当然可根据需要设置executor、scheduler等
3、编写一个测试类完成测试 SchedulerAnnotationTest.java
package com.hode;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath*:*applicationContext-annotation.xml"})
public class SchedulerAnnotationTest {
@Test
public void test() throws Exception{
Thread.sleep(300*1000);
}
}
结束。
