Question

我需要从oracle AQ中读取消息。我正在使用Spring Boot 2.2.0.RELEASE。目前，我只能在我的spring boot应用程序已启动时阅读消息。但是，如果AQ已将消息放入队列，则不会将其出队。我不知道怎么了。

我的配置类：


@Configuration
@EnableJms
public class BridgeConfiguration {

    @Bean
    DataSource dataSource() throws SQLException {
        OracleDataSource dataSource = new OracleDataSource();
        dataSource.setUser("user");
        dataSource.setPassword("pwd");
        dataSource.setURL("jdbc:oracle:thin:host:1521/sid");
        dataSource.setImplicitCachingEnabled(true);
        dataSource.setFastConnectionFailoverEnabled(true);
        return dataSource;
    }

    @Bean
//    @Qualifier(value = "aqconnectionFactory")
    public QueueConnectionFactory aqconnectionFactory() throws Exception {
        return AQjmsFactory.getQueueConnectionFactory(dataSource());
    }

    @Bean
    public PlatformTransactionManager transactionManager() throws Exception {
        JmsTransactionManager jmsTransactionManager = new JmsTransactionManager();
        jmsTransactionManager.setConnectionFactory(aqconnectionFactory());
        return jmsTransactionManager;
    }



    @Bean
    public JmsListenerContainerFactory jmsListenerContainerFactory() throws Exception {
         DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(aqconnectionFactory());
        factory.setTransactionManager(transactionManager());
        factory.setSessionTransacted(true);
        return factory;
    }

}

我的听众课

@Component
public class AqDaoImpl {

@JmsListener(destination = "IBMBRIDGE_OUT", concurrency = "3-10")
    public void getMessage(String message) {
        try{
            System.out.println(message + " received on " + Thread.currentThread().getName());
        }catch (Exception e ){
            System.out.println(e);
        }
    }
}

我希望我将能够接收已经入队的消息。但是，如果我关闭我的应用程序，将一些消息放入oracle aq中，然后打开它的应用程序无法接收到该消息，则消息会保留在oracle aq中。
