在通过spring配置时我们是否需要启动ActiveMQ？

Question

当我尝试使用spring jms集成测试activemq时，我得到连接拒绝错误。我需要启动activemq服务器吗？根据我的理解，当我设置brokerconnction时，spring将拥有启动活动mq的所有方法

源

@SpringBootApplication
@EnableJms
public class Application {
    @Bean
    public DefaultJmsListenerContainerFactory myJmsContainerFactory() {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory());
        return factory;
    }
    @Bean
    public JmsTemplate jmsTemplate(){
        JmsTemplate jmsTemplate = new JmsTemplate();
        jmsTemplate.setDefaultDestination(new ActiveMQQueue("jms.queue"));
        jmsTemplate.setConnectionFactory(connectionFactory());
        return jmsTemplate;
    }

    @Bean
    public ActiveMQConnectionFactory connectionFactory(){
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory("tcp://:61616");
        activeMQConnectionFactory.setBrokerURL("tcp://localhost:61616");
        return activeMQConnectionFactory;
    }
    public static void main(String[] args){
        // Clean out any ActiveMQ data from previous run
        FileSystemUtils.deleteRecursively(new File("activemq-data"));

        // Launch the application
        ConfigurableApplicationContext context = SpringApplication.run(Application.class, args);

        // Send a message
        MessageCreator messageCreator = new MessageCreator() {

            @Override
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("ping!");
            }
        };

        JmsTemplate jmsTemplate = context.getBean(JmsTemplate.class);
        System.out.println("Sending a new message");
        jmsTemplate.send("mailbox-destination", messageCreator);
    }
}

如果使用vm://localhost URL，将在vm传输上启动内存代理;如果您使用tcp://...网址，则需要启动外部代理，或者将代理bean添加到您的应用程序中。
