それはなぜ観測を知りたいのですか？executeInternal()がcustomerRepositoryの参照を無効にした理由を知りたいのですが？私は開発中でした春+石英+春データJPA例。この例では、JobDetailFactoryBeanの実装を提供することによって複数のジョブを同時に実行することを検討していました。 jobA.javaクラスでは、私は問題....私はexecuteInternal()理由でcustomerRepositoryインスタンスを使用することはできませんorg.quartz-scheduler executeInternal（JobExecutionContext executionContext）のリポジトリの参照を無効にする理由は何ですか？
JobA.java
@Service
public class JobA extends QuartzJobBean {
private CustomerRepository customerRepository = null;
@Autowired
public JobA(CustomerRepository customerRepository) {
this.customerRepository = customerRepository;
}
public JobA() { }
@Override
protected void executeInternal(JobExecutionContext executionContext) throws JobExecutionException {
System.out.println("~~~~~~~ Job A is runing ~~~~~~~~");
Trigger trigger = executionContext.getTrigger();
System.out.println(trigger.getPreviousFireTime());
System.out.println(trigger.getNextFireTime());
getCustomerList();
}
private List<Customer> getCustomerList(){
List<Customer> customers = customerRepository.findAll();
for (Customer customer : customers) {
System.out.println("------------------------------");
System.out.println("ID : "+customer.getId());
System.out.println("NAME : "+customer.getName());
System.out.println("STATUS : "+customer.getStatus());
}
return customers;
}
}
を体験しますか？もし私がgetCustomerList()から公衆JobA(CustomerRepository customerRepository) {それはうまく動作しますが、私はexecuteInternal()から使用すると、それはcustomerRepositoryの参照を無効にする理由は？
