Spring Boot配置多个ActiveMQ实例
我需要将消息从一个ActiveMQ实例上的队列移动到另一个ActiveMQ实例上。是否可以使用Spring
Boot配置连接到两个不同的ActiveMQ实例？
我需要创建多个connectionFactories吗？如果是这样，那么JmsTemplate如何知道要连接到哪个ActiveMQ实例？
@Bean public ConnectionFactory connectionFactory() {
return new ActiveMQConnectionFactory(JMS_BROKER_URL);
}
任何帮助和代码示例将很有用。

除了@Chris的响应之外，您还必须使用不同的端口创建不同的BrokerService实例，并创建不同的ConnectionFactory以连接到每个代理，并使用这些不同的工厂向不同的代理发送消息，从而创建不同的JmsTemplate。
例如 ：
import javax.jms.ConnectionFactory;import javax.jms.QueueConnectionFactory;
import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.activemq.broker.BrokerService;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerContainerFactory;
import org.springframework.jms.core.JmsTemplate;
@Configuration
public class ActiveMQConfigurationForJmsCamelRouteConsumeAndForward {
public static final String LOCAL_Q = "localQ";
public static final String REMOTE_Q = "remoteQ";
@Bean
public BrokerService broker() throws Exception {
final BrokerService broker = new BrokerService();
broker.addConnector("tcp://localhost:5671");
broker.setBrokerName("broker");
broker.setUseJmx(false);
return broker;
}
@Bean
public BrokerService broker2() throws Exception {
final BrokerService broker = new BrokerService();
broker.addConnector("tcp://localhost:5672");
broker.setBrokerName("broker2");
broker.setUseJmx(false);
return broker;
}
@Bean
@Primary
public ConnectionFactory jmsConnectionFactory() {
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:5671");
return connectionFactory;
}
@Bean
public QueueConnectionFactory jmsConnectionFactory2() {
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:5672");
return connectionFactory;
}
@Bean
@Primary
public JmsTemplate jmsTemplate() {
JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setConnectionFactory(jmsConnectionFactory());
jmsTemplate.setDefaultDestinationName(LOCAL_Q);
return jmsTemplate;
}
@Bean
public JmsTemplate jmsTemplate2() {
JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setConnectionFactory(jmsConnectionFactory2());
jmsTemplate.setDefaultDestinationName(REMOTE_Q);
return jmsTemplate;
}
@Bean
public JmsListenerContainerFactory<?> jmsListenerContainerFactory(ConnectionFactory connectionFactory,
DefaultJmsListenerContainerFactoryConfigurer configurer) {
DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
configurer.configure(factory, connectionFactory);
return factory;
}
@Bean
public JmsListenerContainerFactory<?> jmsListenerContainerFactory2(
@Qualifier("jmsConnectionFactory2") ConnectionFactory connectionFactory,
DefaultJmsListenerContainerFactoryConfigurer configurer) {
DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
configurer.configure(factory, connectionFactory);
return factory;
}
}
请注意，通过下面的示例，您不能在要从其转发消息的队列上拥有多个使用者，因为Camel或JmsBridgeConnectors会使用该消息并进行转发。如果只希望转发邮件的副本，则可以采用以下解决方案：1-将队列转换为主题，通过持久订阅或追溯使用者来管理脱机使用者的邮件。2-将您的队列转换为复合队列，并使用DestinationsInterceptors将消息复制到另一个队列。3-将NetworkConnector用于经纪人网络
@Beanpublic BrokerService broker() throws Exception {
final BrokerService broker = new BrokerService();
broker.addConnector("tcp://localhost:5671");
SimpleJmsQueueConnector simpleJmsQueueConnector = new SimpleJmsQueueConnector();
OutboundQueueBridge bridge = new OutboundQueueBridge();
bridge.setLocalQueueName(LOCAL_Q);
bridge.setOutboundQueueName(REMOTE_Q);
OutboundQueueBridge[] outboundQueueBridges = new OutboundQueueBridge[] { bridge };
simpleJmsQueueConnector.getReconnectionPolicy().setMaxSendRetries(ReconnectionPolicy.INFINITE);
simpleJmsQueueConnector.setOutboundQueueBridges(outboundQueueBridges);
simpleJmsQueueConnector.setLocalQueueConnectionFactory((QueueConnectionFactory) jmsConnectionFactory());
simpleJmsQueueConnector.setOutboundQueueConnectionFactory(jmsConnectionFactory2());
JmsConnector[] jmsConnectors = new JmsConnector[] { simpleJmsQueueConnector };
broker.setJmsBridgeConnectors(jmsConnectors);
broker.setBrokerName("broker");
broker.setUseJmx(false);
return broker;
}
@Beanpublic CamelContext camelContext() throws Exception {
CamelContext context = new DefaultCamelContext();
context.addComponent("inboundQueue", ActiveMQComponent.activeMQComponent("tcp://localhost:5671"));
context.addComponent("outboundQueue", ActiveMQComponent.activeMQComponent("tcp://localhost:5672"));
context.addRoutes(new RouteBuilder() {
public void configure() {
from("inboundQueue:queue:" + LOCAL_Q).to("outboundQueue:queue:" + REMOTE_Q);
}
});
context.start();
return context;
