Spring and Quartz integration with Java Config
提问by hadi
I searched a lot, but i couldn't fine any post or comment or any complete code on integrating spring and quartz and store the quartz config in database with java config (XML-LESS) could anyone help me and show me some code or reference ? thanks a lot
我搜索了很多，但我无法找到任何关于集成 spring 和石英的帖子或评论或任何完整的代码，并将石英配置存储在带有 java 配置（XML-LESS）的数据库中，任何人都可以帮助我并向我展示一些代码或参考? 多谢

We can implement it like this -
1) Annotations
我们可以像这样实现它 -
1) 注释
Class level Annotation :
Only this class will be scan for quartz support-
班级注释：
只有这个班级会扫描石英支持-
package com.example.config;
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Target({ ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface QuartzJob{
}
Method Level Annotation : Annotation holds property of quartz configuration
方法级注释：注释持有石英配置的属性
package com.example.config;
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Target({ ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Cron {
String name();
String group() default "DEFAULT_GROUP";
String cronExp();
String timeZone() default "Europe/London";
}
2) create Beans holding methods to run as cron job
2) 创建 Beans 持有方法作为 cron 作业运行
package com.example.job;
public class AnotherBean {
public void print(){
System.out.println("I am printing in another bean");
}
}
package com.example.job;
import org.springframework.beans.factory.annotation.Autowired;
import com.example.config.Cron;
import com.example.config.QuartzJob;
@QuartzJob
public class MyJobOne {
@Autowired
private AnotherBean anotherBean;
protected void myTask() {
System.out.println("This is my task");
}
protected void myTask1() {
System.out.println("This is love task");
}
@Cron(name="abc", cronExp="* * * * * ? *", timeZone="Asia/Kolkata")
protected void scheduleMyJob() {
System.out.println("This is lovely task");
anotherBean.print();
}
@Cron(name="xyz", cronExp="0 35 9 ? * MON-FRI", timeZone="Asia/Kolkata")
protected void scheduleMyJob1() {
System.out.println("This is hate task");
}
}
3) Listener to look into bean and initiate Job
3）监听bean并启动Job
package com.example.config;
import java.lang.reflect.Method;
import java.text.ParseException;
import java.util.ArrayList;
import java.util.GregorianCalendar;
import java.util.List;
import java.util.Map;
import java.util.Set;
import java.util.TimeZone;
import org.quartz.CronScheduleBuilder;
import org.quartz.CronTrigger;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.scheduling.quartz.CronTriggerFactoryBean;
import org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.util.ReflectionUtils;
import org.springframework.util.ReflectionUtils.MethodCallback;
public class QuartJobSchedulingListener implements ApplicationListener<ContextRefreshedEvent>
{
@Override
public void onApplicationEvent(ContextRefreshedEvent event)
{
try
{
ApplicationContext applicationContext = event.getApplicationContext();
List<CronTrigger> cronTriggerBeans = this.loadCronTriggerBeans(applicationContext);
if(cronTriggerBeans.size() > 0){
SchedulerFactoryBean schedulerFactoryBean = applicationContext.getBean(SchedulerFactoryBean.class, cronTriggerBeans);
schedulerFactoryBean.start();
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
private List<CronTrigger> loadCronTriggerBeans(ApplicationContext applicationContext)
{
Map<String, Object> quartzJobBeans = applicationContext.getBeansWithAnnotation(QuartzJob.class);
Set<String> beanNames = quartzJobBeans.keySet();
List<CronTrigger> cronTriggerBeans = new ArrayList<CronTrigger>();
for (String beanName : beanNames)
{
Object bean = quartzJobBeans.get(beanName);
ReflectionUtils.doWithMethods(bean.getClass(), new MethodCallback(){
@Override
public void doWith(Method method) throws IllegalArgumentException, IllegalAccessException {
if(method.isAnnotationPresent(Cron.class)){
Cron cron = method.getAnnotation(Cron.class);
System.out.println("Scheduling a job for "+ bean.getClass()+ " and method "+method.getName());
MethodInvokingJobDetailFactoryBean jobDetailFactoryBean = new MethodInvokingJobDetailFactoryBean();
jobDetailFactoryBean.setName(beanName+"."+cron.name()+"."+method.getName());
jobDetailFactoryBean.setTargetMethod(method.getName());
jobDetailFactoryBean.setTargetObject(bean);
try {
jobDetailFactoryBean.afterPropertiesSet();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchMethodException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
CronTriggerFactoryBean triggerFactoryBean = new CronTriggerFactoryBean();
triggerFactoryBean.setJobDetail(jobDetailFactoryBean.getObject());
triggerFactoryBean.setName(beanName+"_trigger_"+method.getName());
triggerFactoryBean.setCronExpression(cron.cronExp());
GregorianCalendar calendar = new GregorianCalendar(TimeZone.getTimeZone(cron.timeZone()));
System.out.println(calendar.getTime());
triggerFactoryBean.setStartTime(calendar.getTime());
triggerFactoryBean.setTimeZone(TimeZone.getTimeZone(cron.timeZone()));
try {
triggerFactoryBean.afterPropertiesSet();
System.out.println(triggerFactoryBean.getObject().getFinalFireTime());
System.out.println(triggerFactoryBean.getObject().getCronExpression());
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
cronTriggerBeans.add(triggerFactoryBean.getObject());
}
}
});
}
return cronTriggerBeans;
}
public Trigger getCronTrigger(String cronExpression){
CronScheduleBuilder cronScheduleBuilder=null;
Trigger cronTrigger=null;
cronScheduleBuilder=CronScheduleBuilder.cronSchedule(cronExpression);
cronScheduleBuilder.withMisfireHandlingInstructionFireAndProceed();
TriggerBuilder<Trigger> cronTtriggerBuilder=TriggerBuilder.newTrigger();
cronTtriggerBuilder.withSchedule(cronScheduleBuilder);
cronTrigger=cronTtriggerBuilder.build();
return cronTrigger;
}
}
4) Creating JavaConfig class-
4) 创建 JavaConfig 类-
package com.example.config;
import java.util.List;
import org.quartz.CronTrigger;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Scope;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import com.example.job.AnotherBean;
import com.example.job.MyJobOne;
@Configuration
public class QuartzConfiguration {
@Bean
public QuartJobSchedulingListener quartJobSchedulingListener(){
return new QuartJobSchedulingListener();
}
@Bean
public MyJobOne myJobOne(){
return new MyJobOne();
}
@Bean(name="scheduler")
@Scope(value="prototype")
public SchedulerFactoryBean schedulerFactoryBean(List<CronTrigger> triggerFactoryBeans) {
SchedulerFactoryBean scheduler = new SchedulerFactoryBean();
CronTrigger[] cronTriggers = new CronTrigger[triggerFactoryBeans.size()];
cronTriggers = triggerFactoryBeans.toArray(cronTriggers);
scheduler.setTriggers(cronTriggers);
System.out.println(cronTriggers[0].getCronExpression());
System.out.println(cronTriggers[0].getCalendarName());
System.out.println(cronTriggers[0].getTimeZone());
System.out.println(cronTriggers[0].getEndTime());
return scheduler;
}
@Bean
public AnotherBean anotherBean(){
return new AnotherBean();
}
}
5) Creating main class to test it
5）创建主类进行测试
package com.example;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import com.example.config.QuartzConfiguration;
@ComponentScan
@EnableAutoConfiguration
public class Main {
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();
context.register(QuartzConfiguration.class);
context.refresh();
}
}

This is a good example on integrating spring with quartz with spring annotation config (XML-LESS). You can ignore the AutowiringSpringBeanJobFactory and use the standard spring job factory if you don't need inject bean into your job class. Just have a look at this QuartzConfig class.
这是将 spring 与石英与 spring 注释配置 (XML-LESS) 集成的一个很好的例子。如果不需要将 bean 注入作业类，则可以忽略 AutowiringSpringBeanJobFactory 并使用标准的 spring 作业工厂。看看这个 QuartzConfig 类。
