Package edu.ucsb.cs156.jobs.config

Class JobsAutoConfiguration

java.lang.Object

edu.ucsb.cs156.jobs.config.JobsAutoConfiguration

@AutoConfiguration
@AutoConfigurationPackage(basePackages="edu.ucsb.cs156.jobs")
@EnableAsync
@EnableScheduling
public class JobsAutoConfiguration
extends Object

Auto-configuration for the jobs system; activates when the library is on the classpath.

@AutoConfigurationPackage adds edu.ucsb.cs156.jobs to the app's auto-configuration packages, so Spring Boot's default entity and Spring Data repository scanning picks up Job and JobsRepository *in addition to* the app's own classes. (Using @EntityScan/@EnableJpaRepositories here instead would disable that default scanning and break the consuming app's own entities and repositories.)

Every bean is @ConditionalOnMissingBean so an app can override any piece.

The jobsExecutor defaults to a single thread with an unbounded FIFO queue: jobs execute strictly one at a time, in submission order, which prevents two concurrent jobs from racing each other (e.g. double-launching a sync inserting the same rows). Known limitation: the queue is in-memory, so jobs still queued when the app shuts down are lost and their Job rows remain in "running" status. Apps that want concurrency set app.jobs.core-pool-size / app.jobs.max-pool-size / app.jobs.queue-capacity.
