In the new version of SpringBoot2.0the release, I urge the early adopters of the relevant projects have been replaced by the latest version of the SpringBootsource code GitHubto see the update log, indicating for Quartzwas a new version of AutoConfigurationautomated configuration, save a lot of tedious configuration.
The core code implementation
quartz.properties basic configuration properties

Spring QuartzJobFactory.java poured into the container
package top.enjoyitlife.config; import org.quartz.spi.TriggerFiredBundle; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.config.AutowireCapableBeanFactory; import org.springframework.scheduling.quartz.SpringBeanJobFactory; import org.springframework.stereotype.Component; @Component public class QuartzJobFactory extends SpringBeanJobFactory{ @Autowired private AutowireCapableBeanFactory capableBeanFactory; @Override protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception { Object jobInstance = super.createJobInstance(bundle); capableBeanFactory.autowireBean(jobInstance); return jobInstance; } }
QuartzConfig.java configuration class load configuration file to instantiate quartz and property to pay attention to the use of cluster programs need to connect to the database, and memory version is no configuration database

ApplicationListenerConfig.java project start initialization task that is loaded

Server.port application.properties modify the port number, and then re-run QuartzDistributeApplication main method. The following is a screenshot of the double task of service at the same time start, there is now only 1 task logging service 2 no job history.
Stop Task 1 application, and then we will see the following log Print Task 2:
【Tips】
If you want to manually modify the expression CRON task in the cluster, you need to first modify CRON_EXPRESSION expression table QRTZ_CRON_TRIGGERS, and then modify the table QRTZ_TRIGGERS in the NEXT_FIRE_TIME and PREV_FIRE_TIME is 0, after the next task execution, the task execution interval on It will take effect.
To manually remove the timer task cluster, delete table records the following order: QRTZ_CRON_TRIGGERS -----> QRTZ_TRIGGERS ----> QRTZ_JOB_DETAILS, mainly due to the presence of the foreign key is deleted according to the order.
