Question

我试图让一个拥有activeMq经纪人的Jms消费者拥有＆＃34;事务性＆＃34;确认。我想使用spring boot应用程序。

我读到我需要JTA交易，但我不知道如何开始交易。

我的主要课程：

@SpringBootApplication
@EnableJms
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

我的消费者：

@Component
public class ReceiveMessage {
    @JmsListener(destination = "${jms.queue.destination}")
    public void receiveMessage(final String msg) throws Exception {
        System.out.println("Received:" + msg);
    }
}

我的pom.xml依赖：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-activemq</artifactId>
    </dependency>
</dependencies>

我必须做什么？

更新您的消费者：

@Component
public class ReceiveMessage {
    @JmsListener(destination = "${jms.queue.destination}", containerFactory = "jmsListenerContainerFactory")
    public void receiveMessage(final String msg) throws Exception {
        System.out.println("Received:" + msg);
    }
}

添加这些bean：

@Bean
public JmsListenerContainerFactory<?> jmsListenerContainerFactory(
        ConnectionFactory connectionFactory,
        DefaultJmsListenerContainerFactoryConfigurer configurer) {
    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    configurer.configure(factory, connectionFactory);
    factory.setTransactionManager(transactionManager());
    return factory;
}

@Bean
public PlatformTransactionManager transactionManager() {
    JmsTransactionManager transactionManager = new JmsTransactionManager();
    transactionManager.setConnectionFactory(jmsConnectionFactory());
    return transactionManager;
}

@Bean
public QueueConnectionFactory jmsConnectionFactory() {
    ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:5672");
    return connectionFactory;
}

@JmsListener
