1、新增pom依赖
除了按照《quartz2.3.0系列目录——带您由浅入深全面掌握quartz2.3.0》添加依赖之外,pom.xml里新增加依赖:
<dependency>
<groupId>opensymphony</groupId>
<artifactId>quartz-all</artifactId>
<version>1.6.3</version>
</dependency>
<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency>
2、quartz.properties配置

3、quartz_data.xml配置
<?xml version="1.0" encoding="UTF-8"?>

<!-- 如果调度程序中有任何同名的作业/触发器(与此文件中相同),并且覆盖为false,则忽略它们,而不是生成错误 -->
<ignore-duplicates>false</ignore-duplicates>
</processing-directives>
<schedule>
<job>

<job-class>org.quartz.examples.example10.SimpleJob</job-class>

4、任务类,xml配置文件里指向的job任务类
package org.quartz.examples.example10;
import java.util.Date;
import java.util.Set;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.JobKey;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* job任务类
*/
public class SimpleJob implements Job {
private static Logger LOG = LoggerFactory.getLogger(SimpleJob.class);
// 必须要有public修饰的无参构造函数
public SimpleJob() {
}
// 定时器执行方法
@SuppressWarnings("unchecked")
public void execute(JobExecutionContext context) throws JobExecutionException {
JobKey jobKey = context.getJobDetail().getKey();
LOG.info("--------- job任务执行: " + jobKey + " executing at " + new Date() + ", fired by: "
+ context.getTrigger().getKey());
if (context.getMergedJobDataMap().size() > 0) {
Set<String> keys = context.getMergedJobDataMap().keySet();
for (String key : keys) {
String val = context.getMergedJobDataMap().getString(key);
LOG.info("--------- job任务执行。 - jobDataMap entry: " + key + " = " + val);
}
}
context.setResult("hello");
}
}
5、PlugInExample调度器类
package org.quartz.examples.example10;
import org.quartz.Scheduler;
import org.quartz.SchedulerFactory;
import org.quartz.SchedulerMetaData;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* 这个示例将生成大量要运行的作业
*/
public class PlugInExample {
public void run() throws Exception {
Logger log = LoggerFactory.getLogger(PlugInExample.class);
// 初始化一个调度工厂,并实例化一个调度类
SchedulerFactory sf = new StdSchedulerFactory();
Scheduler sched = null;
try {
sched = sf.getScheduler();
} catch (NoClassDefFoundError e) {
log.error(" 无法加载类——很可能类路径上没有jta.jar。 如果在examples/lib文件夹中没有,请将它添加到这里,以便运行这个示例。", e);
return;
}
log.info("----------- 不调度任何作业——依赖于XML定义 ");
sched.start();
Thread.sleep(300L * 1000L);
sched.shutdown(true);
SchedulerMetaData metaData = sched.getMetaData();
log.info("Executed " + metaData.getNumberOfJobsExecuted() + " jobs.");
}
public static void main(String[] args) throws Exception {
PlugInExample example = new PlugInExample();
example.run();
}
}
