[英]Spring-Boot: how to access multiple JMS broker-url's
In Spring-Boot the default ActiveMQ (JMS) properties are:在 Spring-Boot 中,默认的 ActiveMQ (JMS) 属性是:
spring.activemq.broker-url=tcp://192.168.1.210:9876
spring.activemq.user=admin
spring.activemq.password=secret
if I want to send to more than one broker-url or listen different broker-urls how to do it?如果我想发送到多个 broker-url 或收听不同的 broker-url 怎么做?
spring.activemq.broker-url= # URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616`
spring.activemq.in-memory=true # Specify if the default broker URL should be in memory. Ignored if an explicit broker has been specified.
spring.activemq.password= # Login password of the broker.
spring.activemq.user= # Login user of the broker.
Make spring.activemq.in-memory=false
.使spring.activemq.in-memory=false
。 If it is true, then it will read from memory and you will get another one.如果它是真的,那么它会从内存中读取,你会得到另一个。 Hope it will help.希望它会有所帮助。

You cannot access two different brokers with the default Spring-Boot
auto configuration.您无法使用默认的Spring-Boot
自动配置访问两个不同的代理。
For resolving this you have to create your own configuration Bean like in the following example:为了解决这个问题,你必须像下面的例子一样创建你自己的配置 Bean:
@Configuration
class JmsUtilsConfiguration {
@Value("${activemq.broker-one.url}")
private String brokerOneUrl;
// Im my case, broker-two is secured -> hence username and password need to be configured
@Value("${activemq.broker-two.url}")
private String brokerTwoUrl;
@Value("${activemq.broker-two.username}")
private String brokerTwoUser;
@Value("${activemq.broker-two.password}")
private String brokerTwoPwd;
@Bean
@Primary
public ConnectionFactory jmsConnectionFactoryOne() {
return new ActiveMQConnectionFactory(brokerOneUrl);
}
@Bean
public QueueConnectionFactory jmsConnectionFactoryTwo() {
ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();
activeMQConnectionFactory.setBrokerURL(brokerTwoUrl);
activeMQConnectionFactory.setUserName(brokerTwoUser);
activeMQConnectionFactory.setPassword(brokerTwoPwd);
return activeMQConnectionFactory;
}
// JmsListenerContainerFactory declarations
@Bean
public JmsListenerContainerFactory<?> jmsListenerContainerFactoryOne(
ConnectionFactory connectionFactory, DefaultJmsListenerContainerFactoryConfigurer configurer) {
DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
configurer.configure(factory, connectionFactory);
return factory;
}
@Bean
public JmsListenerContainerFactory<?> jmsListenerContainerFactoryTwo(
@Qualifier("jmsConnectionFactoryTwo") ConnectionFactory connectionFactory,
DefaultJmsListenerContainerFactoryConfigurer configurer) {
DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
configurer.configure(factory, connectionFactory);
return factory;
}
// JMS Template Declaration
@Bean
@Primary
public JmsTemplate jmsTemplateOne() {
JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setConnectionFactory(jmsConnectionFactoryOne());
return jmsTemplate;
}
@Bean
public JmsTemplate jmsTemplateTwo() {
JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setConnectionFactory(jmsConnectionFactoryTwo());
return jmsTemplate;
}
}
In my application.yml
I just refer to the injected propertie ( without setting the default spring.activemq
ones):在我的application.yml
我只是引用了注入的属性(没有设置默认的spring.activemq
):
activemq:
broker-one:
url: tcp://localhost:61616
local-queue: TEST.LOCAL.INBOUND
broker-two:
url: failover:(ssl://myremote-amq-1:61617,ssl://myremote-amq-2:61617)?jms.watchTopicAdvisories=false&timeout=5000&maxReconnectDelay=10000
username: myuser
password: mypass
remote-queue: TEST.REMOTE.QUEUE
and in my listener Bean (assuming I just want to consume from both queues)并在我的侦听器 Bean 中(假设我只想从两个队列中消费)
@Component
public class ConsumeQueuesBean {
private static final Logger LOGGER = LoggerFactory.getLogger(ConsumeQueuesBean.class);
@JmsListener(destination = "${activemq.broker-one.local-queue}", containerFactory = "jmsListenerContainerFactoryOne")
public void onMessageReceiveB1(final Message message) throws JMSException {
if (message instanceof TextMessage) {
String text = ((TextMessage) message).getText();
LOGGER.info(text);
}
}
@JmsListener(destination = "${activemq.broker-two.remote-queue}", containerFactory = "jmsListenerContainerFactoryTwo")
public void onMessageReceivedB2(final Message message) throws JMSException {
if (message instanceof TextMessage) {
String text = ((TextMessage) message).getText();
LOGGER.info(text);
}
}
}
You can also use the jmsTemplates
defined in the config for posting message to the broker you want.您还可以使用配置中定义的jmsTemplates
将消息发布到您想要的代理。
