内容图文
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
#============================================================================ # Configure Main Scheduler Properties #============================================================================ org.quartz.scheduler.instanceName: TestScheduler org.quartz.scheduler.instanceId: AUTO #============================================================================ # Configure ThreadPool #============================================================================ org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool org.quartz.threadPool.threadCount: 3 org.quartz.threadPool.threadPriority: 5 #============================================================================ # Configure JobStore #============================================================================ org.quartz.jobStore.misfireThreshold: 60000 org.quartz.jobStore.class: org.quartz.simpl.RAMJobStore #============================================================================ # Configure Plugins #============================================================================ org.quartz.plugin.triggHistory.class: org.quartz.plugins.history.LoggingJobHistoryPlugin org.quartz.plugin.jobInitializer.class: org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin org.quartz.plugin.jobInitializer.fileNames: quartz_data.xml org.quartz.plugin.jobInitializer.failOnFileNotFound: true org.quartz.plugin.jobInitializer.scanInterval: 120 org.quartz.plugin.jobInitializer.wrapInUserTransaction: false
3、quartz_data.xml配置
<?
xml version="1.0" encoding="UTF-8"
?>
<
job-scheduling-data
xmlns
="http://www.quartz-scheduler.org/xml/JobSchedulingData"
xmlns:xsi
="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation
="http://www.quartz-scheduler.org/xml/JobSchedulingData http://www.quartz-scheduler.org/xml/job_scheduling_data_1_8.xsd"
version
="1.8"
>
<

>
<

>*</delete-jobs-in-group><!-- 清除调度器中的所有作业 --><delete-triggers-in-group>*</delete-triggers-in-group><!-- 清除调度器中的所有触发器 --></pre-processing-commands><processing-directives><!-- 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)，会覆盖它们 --><overwrite-existing-data>true</overwrite-existing-data><!-- 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><name>TestJob1</name><job-class>org.quartz.examples.example10.SimpleJob</job-class></job><job><name>TestDurableJob</name><job-class>org.quartz.examples.example10.SimpleJob</job-class><durability>true</durability><recover>false</recover></job><trigger><simple><name>TestSimpleTrigger1AtFiveSecondInterval</name><job-name>TestJob1</job-name><repeat-count>-1</repeat-count><!-- repeat indefinitely --><repeat-interval>5000</repeat-interval><!-- every 5 seconds --></simple></trigger><job><name>TestJob2</name><group>GroupOfTestJob2</group><description>This is the description of TestJob2</description><job-class>org.quartz.examples.example10.SimpleJob</job-class><durability>false</durability><recover>true</recover><job-data-map><entry><key>someKey</key><value>someValue</value></entry><entry><key>someOtherKey</key><value>someOtherValue</value></entry></job-data-map></job><trigger><simple><name>TestSimpleTrigger2AtTenSecondIntervalAndFiveRepeats</name><group>GroupOfTestJob2Triggers</group><job-name>TestJob2</job-name><job-group>GroupOfTestJob2</job-group><start-time>2010-02-09T10:15:00</start-time><misfire-instruction>MISFIRE_INSTRUCTION_RESCHEDULE_NOW_WITH_EXISTING_REPEAT_COUNT</misfire-instruction><repeat-count>5</repeat-count><repeat-interval>10000</repeat-interval></simple></trigger><trigger><cron><name>TestCronTrigger2AtEveryMinute</name><group>GroupOfTestJob2Triggers</group><job-name>TestJob2</job-name><job-group>GroupOfTestJob2</job-group><job-data-map><entry><key>someKey</key><value>overriddenValue</value></entry><entry><key>someOtherKey</key><value>someOtherOverriddenValue</value></entry></job-data-map><cron-expression>0 * * ? * *</cron-expression></cron></trigger><trigger><cron><name>TestCronTrigger2AtEveryMinuteOnThe45thSecond</name><group>GroupOfTestJob2Triggers</group><job-name>TestJob2</job-name><job-group>GroupOfTestJob2</job-group><start-time>2010-02-09T12:26:00.0</start-time><end-time>2012-02-09T12:26:00.0</end-time><misfire-instruction>MISFIRE_INSTRUCTION_SMART_POLICY</misfire-instruction><cron-expression>45 * * ? * *</cron-expression><time-zone>America/Los_Angeles</time-zone></cron></trigger></schedule></job-scheduling-data>
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 {
privatestatic 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")
publicvoid 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.");
}
publicstaticvoid main(String[] args) throws Exception {
PlugInExample example = new PlugInExample();
example.run();
}
}
