Spring Boot offers several conveniences for working with the Quartz scheduler, including the spring-boot-starter-quartz “Starter”. If Quartz is available, a Scheduler is auto-configured (through the SchedulerFactoryBean abstraction).

Beans of the following types are automatically picked up and associated with the Scheduler:

By default, an in-memory JobStore is used. However, it is possible to configure a JDBC-based store if a DataSource bean is available in your application and if the spring.quartz.job-store-type property is configured accordingly, as shown in the following example:

spring.quartz.job-store-type=jdbc

When the JDBC store is used, the schema can be initialized on startup, as shown in the following example:

spring.quartz.jdbc.initialize-schema=always

	Note
	By default, the database is detected and initialized by using the standard scripts provided with the Quartz library. It is also possible to provide a custom script by setting the spring.quartz.jdbc.schema property.

Quartz Scheduler configuration can be customized by using Quartz configuration properties ()spring.quartz.properties.*) and SchedulerFactoryBeanCustomizer beans, which allow programmatic SchedulerFactoryBean customization.

Jobs can define setters to inject data map properties. Regular beans can also be injected in a similar manner, as shown in the following example:

public class SampleJob extends QuartzJobBean {

	private MyService myService;

	private String name;

	// Inject "MyService" bean
	public void setMyService(MyService myService) { ... }

	// Inject the "name" job data property
	public void setName(String name) { ... }

	@Override
	protected void executeInternal(JobExecutionContext context)
			throws JobExecutionException {
		...
	}

}
