Example 6 with Singleton

use of jakarta.inject.Singleton in project micronaut-camunda-bpm by camunda-community-hub.

the class ProcessEngineFactory method processEngine.

@Singleton
@Bean(preDestroy = "close")
public ProcessEngine processEngine(ProcessEngineConfiguration processEngineConfiguration, CamundaVersion camundaVersion, SynchronousTransactionManager<Connection> transactionManager, BasicJdbcConfiguration basicJdbcConfiguration, ParallelInitializationService parallelInitializationService) {
    if (camundaVersion.getVersion().isPresent()) {
        log.info("Camunda version: {}", camundaVersion.getVersion().get());
    } else {
        log.warn("The Camunda version cannot be determined. If you created a Fat/Uber/Shadow JAR then please consider using the Micronaut Application Plugin's 'dockerBuild' task to create a Docker image.");
    }
    log.info("Building process engine connected to {}", basicJdbcConfiguration.getUrl());
    Instant start = Instant.now();
    ProcessEngine processEngine = transactionManager.executeWrite(transactionStatus -> processEngineConfiguration.buildProcessEngine());
    log.info("Started process engine in {}ms", ChronoUnit.MILLIS.between(start, Instant.now()));
    log.debug("Starting Camunda related services...");
    parallelInitializationService.process(processEngine);
    log.debug("Camunda related services started in {}ms", ChronoUnit.MILLIS.between(start, Instant.now()));

Example 8 with Singleton

use of jakarta.inject.Singleton in project glassfish-hk2 by eclipse-ee4j.

the class Populator method populate.

    config.bind(BuilderHelper.link(HttpRequest.class).in(RequestScope.class.getName()).build());
    // The HttpServer is a singleton
    config.bind(BuilderHelper.link(HttpServer.class).in(Singleton.class.getName()).build());
    // The RequestContext is the context implementation for RequestScope
    config.bind(BuilderHelper.link(RequestContext.class).to(Context.class).in(Singleton.class.getName()).build());
    // RequestProcessor processes a request from an HttpServer
    config.bind(BuilderHelper.link(RequestProcessor.class).build());
    // The logger is just another service to be injected
    config.bind(BuilderHelper.link(Logger.class).in(Singleton.class.getName()).build());
    // And commit
    config.commit();
}
