Logré configurar y programar un trabajo Quartz usando la tienda persistente JobStoreTX en Spring. No uso los trabajos de Spring Quartz, porque necesito programarlos dinámicamente, en tiempo de ejecución, y todos los ejemplos de integración de Spring con Quartz que encontré fueron codificación rígida de los shcedules en los archivos de configuración de Spring ... De todos modos, aquí es cómo Yo programo el trabajo:
JobDetail emailJob = JobBuilder.newJob(EMailJob.class)
.withIdentity("someJobKey", "immediateEmailsGroup")
.storeDurably()
.build();
SimpleTrigger trigger = (SimpleTrigger) TriggerBuilder.newTrigger()
.withIdentity("someTriggerKey", "immediateEmailsGroup")
.startAt(fireTime)
.build();
// pass initialization parameters into the job
emailJob.getJobDataMap().put(NotificationConstants.MESSAGE_PARAMETERS_KEY, messageParameters);
emailJob.getJobDataMap().put(NotificationConstants.RECIPIENT_KEY, recipient);
if (!scheduler.checkExists(jobKey) && scheduler.getTrigger(triggerKey) != null) {
// schedule the job to run
Date scheduleTime1 = scheduler.scheduleJob(emailJob, trigger);
}
EMailJob es un trabajo simple que consiste en enviar correo electrónico utilizando la clase JavaMailSenderImpl de Spring.
public class EMailJob implements Job {
@Autowired
private JavaMailSenderImpl mailSenderImpl;
public EMailJob() {
}
public void execute(JobExecutionContext context)
throws JobExecutionException {
....
try {
mailSenderImpl.send(mimeMessage);
} catch (MessagingException e) {
....
throw new JobExecutionException("EMailJob failed: " + jobKey.getName(), e);
}
logger.info("EMailJob finished OK");
}
El problema es que necesito obtener una referencia a una instancia de esta clase (JavaMailSenderImpl) en mi clase EMailJob. Cuando trato de inyectarlo así:
@Autowired
private JavaMailSenderImpl mailSenderImpl;
no se inyecta - la referencia es NULL. Supongo que esto está sucediendo porque no es Spring quien instancia la clase EMailJob, sino Quartz, y Quartz no sabe nada sobre la inyección de dependencia ...
Entonces, ¿hay alguna forma de forzar que se produzca esta inyección?
¡Gracias!
Actualización 1: @Aaron: aquí hay una parte relevante del seguimiento de la pila desde el inicio, que muestra que el EMailJob se instancia dos veces:

Actualización # 2: @Ryan:
Traté de usar SpringBeanJobFactory de la siguiente manera:
<bean id="jobFactoryBean" class="org.springframework.scheduling.quartz.SpringBeanJobFactory">
</bean>
<bean id="schedulerFactoryBean" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="configLocation" value="classpath:spring/quartz.properties"/>
<property name="jobFactory" ref="jobFactoryBean"/>
</bean>
Y modifiqué mi clase principal para obtener el Programador de esta fábrica, en lugar de Quartz ':
@PostConstruct
public void initNotificationScheduler() {
try {
//sf = new StdSchedulerFactory("spring/quartz.properties");
//scheduler = sf.getScheduler();
scheduler = schedulerFactoryBean.getScheduler();
scheduler.start();
....
Pero cuando ejecuto la aplicación, obtengo errores, vea a continuación. Aquí está el stacktrace del inicio de Spring. Parece que el Programador en sí está bien creado, pero el error se produce cuando intenta crear una instancia de mi EMailJob:
