After the release of the new version of SpringBoot2.0, I was eager to try something new and changed the relevant project to the latest version. I saw the update log on GitHub source code of SpringBoot, indicating that AutoConfiguration has been automatically configured for the new version of Quartz. Saves a lot of tedious configuration.
Official website update log
Auto-configuration support is now included for the Quartz Scheduler. We’ve also added a new spring-boot-starter-Quartz starter POM. You can use in-memory JobStores, or a full JDBC-based store. All JobDetail, Calendar and Trigger beans from your Spring application context will be automatically registered with the Scheduler. For more details read the new “Quartz Scheduler” section of the reference documentation.
SpringBoot2.0 integrates with the latest version of Quartz2.3.0.
Objective in this chapter
Automated Quartz configuration with new SpringBoot2.0 features.

Build the project
In the previous chapter, Chapter 40: Implementing Scheduled Task Distributed Multi-node Load Persistence based on SpringBoot & Quartz, we have completed the integration by adding configuration. For the convenience of this chapter, we have directly copied the previous project and modified it on the basis. Open the pm. XML configuration file and SpringBoot provides corresponding dependencies for us. We delete the previous Quartz dependencies and replace them with spring-boot-starter-Quartz, as shown below:
<! Scheduler </artifactId> </artifactId> <version>${quartz.version}</version>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz-jobs</artifactId>
<version>${quartz.version}</version> </dependency> >>>> replace with: >>>> <! --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-quartz</artifactId> </dependency> ......Copy the codeDelete the QuartzConfiguration configuration class
In the previous section, we used the QuartzConfiguration class to complete a series of configurations for Quartz, such as: JobFactory, SchedulerFactoryBean, etc., do not need to actively declare the factory class after we add the spring-boot-starter-Quartz dependency, because spring-boot-starter-Quartz is already configured for us automatically.
Automatic configuration source code
External Libraries: spring-boot-autoconfigure-2.0.0.release.jar Find the org. Springframework. Boot. Autoconfigure. Quartz, the directory is SpringBoot provide us quartz automation configuration source, in that directory are shown in the following several kinds:
AutowireCapableBeanJobFactoryThis class replaces our previous one inQuartzConfigurationConfiguration of the classAutowiringSpringBeanJobFactoryThe inner class implementation, the main role is our customQuartzJobBeanSubclasses areSpring IOCFor hosting, you can use injection anywhere in the scheduled task classSpring IOCManaged classes.JobStoreTypeThis class is an enumerated type that defines the correspondingapplication.yml,application.propertiesIn the filespring.quartz.job-store-typeConfiguration, whose purpose is to configurequartzThe data storage modes of tasks are as follows: MEMORYThe default), JDBC (database mode).QuartzAutoConfigurationThis class is the main class for automatic configuration and is configured internallySchedulerFactoryBeanAs well asJdbcStoreTypeConfiguration, the use ofQuartzPropertiesAutomate configuration conditions as properties.QuartzDataSourceInitializerThis class is mainly used for some operations after data source initialization.

Spring. The quartz configuration
See QuartzAutoConfiguration source code, we know, to use automatic configuration, need to meet the QuartzProperties property configuration class initialization, Therefore, we need to add the corresponding configuration information to the application.yml and application.properties configuration files, as follows:
spring:
quartz:
# Configure related attributes
properties:
org:
quartz:
scheduler:
instanceName: clusteredScheduler
instanceId: AUTO
jobStore:
class: org.quartz.impl.jdbcjobstore.JobStoreTX
driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
tablePrefix: QRTZ_
isClustered: true
clusterCheckinInterval: 10000
useProperties: false
threadPool:
class: org.quartz.simpl.SimpleThreadPool
threadCount: 10
threadPriority: 5
threadsInheritContextClassLoaderOfInitializingThread: true
# database mode
job-store-type: jdbc
Initialize the table structure
#jdbc:
#initialize-schema: never
Copy the codespring.quartz.propertiesThis configuration actually replaces the previous onequartz.properties, we put beforequartz.propertiesAll configurations in the configuration file are converted toYUMLStyle, corresponding to the configuration can be added in theQuartzAutoConfigurationClass, is automatically calledSchedulerFactoryBeanthesetQuartzPropertiesThe method,spring.quartz.propertiesAll the configurations inside are set.
@Bean
@ConditionalOnMissingBean
public SchedulerFactoryBean quartzScheduler() { SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean(); schedulerFactoryBean.setJobFactory(new AutowireCapableBeanJobFactory(this.applicationContext.getAutowireCapableBeanFactory())); // If spring.quartz. Properties is configuredif(! This. The properties. The getProperties (). The isEmpty ()) {/ / set all the properties to QuartzProperties schedulerFactoryBean.setQuartzProperties(this.asProperties(this.properties.getProperties())); }... Omit some codeCopy the codespring.quartz.job-store-typeSet up thequartzThe data persistence mode of the task, by default, is memory mode, we use the previous mode, configurationJDBCPersist tasks using a database.spring.quartz.jdbc.initialize-schema
This configuration is not currently in effect. According to the documentation on the website, it is intended to automatically initialize the data tables required by Quartz.

Of course, if we open multiple nodes, we can also achieve the effect of automatic task drift.
conclusion
To conclude, we have SpringBoot2.0 Quartz integration done, we just need to add dependencies, add configurations, and do nothing else.
