Consegui configurar e agendar um job Quartz usando o armazenamento persistente JobStoreTX no Spring. Eu não uso jobs Quartz do Spring, porque preciso agendá-los dinamicamente, em tempo de execução, e todos os exemplos de integração do Spring com Quartz que encontrei estavam codificando as shcedules nos arquivos de configuração do Spring ... De qualquer forma, aqui está como Eu agendo o trabalho:
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);
}
O EMailJob é um trabalho simples que envia e-mail usando a classe JavaMailSenderImpl do 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");
}
O problema é que preciso obter uma referência a uma instância dessa classe (JavaMailSenderImpl) em minha classe EMailJob. Quando tento injetar assim:
@Autowired
private JavaMailSenderImpl mailSenderImpl;
não é injetado - a referência é NULL. Presumo que isso esteja acontecendo porque não é o Spring que instancia a classe EMailJob, mas o Quartz, e o Quartz não sabe nada sobre injeção de dependência ...
Então, há alguma maneira de forçar essa injeção a acontecer?
obrigado!
Atualização 1: @Aaron: aqui está uma parte relevante do stacktrace da inicialização, que mostra que o EMailJob foi instanciado duas vezes:

Atualização nº 2: @Ryan:
Tentei usar SpringBeanJobFactory da seguinte maneira:
<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>
E eu modifiquei minha classe principal para obter o Scheduler desta fábrica, em vez do Quartz ':
@PostConstruct
public void initNotificationScheduler() {
try {
//sf = new StdSchedulerFactory("spring/quartz.properties");
//scheduler = sf.getScheduler();
scheduler = schedulerFactoryBean.getScheduler();
scheduler.start();
....
Mas quando eu executo o aplicativo - obter erros, veja abaixo. Aqui está o rastreamento de pilha da inicialização do Spring. Parece que o próprio Scheduler foi criado corretamente, mas o erro ocorre quando ele tenta instanciar meu EMailJob:
