quartz 调度任务应用

来源：互联网发布：vmware mac os 10.11 编辑：程序博客网时间：2024/04/30 09:34

maven引入包：

<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.1</version>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz-jobs</artifactId>
<version>2.2.1</version>
</dependency>

1：引入spring调度工厂类

2：编写调度管理类

@Service("quartzManagerJob")
@Scope(ConfigurableBeanFactory.SCOPE_SINGLETON)
public class QuartzManager {

@Resource(name="schedulerFactory")
private Scheduler scheduler;

详细如下：

import org.quartz.*;
import org.quartz.impl.triggers.CronTriggerImpl;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.config.ConfigurableBeanFactory;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

/**
*定时任务
*/
@Service("quartzManagerJob")
@Scope(ConfigurableBeanFactory.SCOPE_SINGLETON)
public class QuartzManager {

public static String pathUrl=QuartzPropertiesUtil.class.getResource("/").getPath()+"task.properties";

@Resource(name="schedulerFactory")

public boolean addOrUpdate(QuartzVO quartzVO){
try{

}else{

3：调度工具类

4:Test类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext_task.xml")
public class QuartzManagerTest {

@Resource(name="quartzManager")
private QuartzManager quartzManager;
@Test
public void queartTest()throws Exception{
quartzManager.addOrUpdateSchedule("2","2","0/5 * * * * ?", One.class);
Thread.sleep(2000);
quartzManager.addOrUpdateSchedule("1", "3", "0/5 * * * * ?", Two.class);
Thread.sleep(2000);
quartzManager.addOrUpdateSchedule("1", "3", "0/2 * * * * ?", Two.class);
quartzManager.findTrigger("1","3");
Thread.sleep(1000000);
}

@Test
public void queartTest2(){
quartzManager.addOrUpdateSchedule("2", "2", "0/5 * * * * ?", Two.class);
}
}
