我有一个使用xml配置的弹簧集成+ rabbitmq应用程序。现在,我将它们转换为java配置注释。对于某些主要的amqp对象,例如Queue
,TopicExchange
和Binding
,有可用的类和java注释。但是,我无法在将inbound-gateway
和outbound-gateway
转换为java注释或类实现时找到任何参考。
这是我的实施: // gateway.xml
<int-amqp:outbound-gateway request-channel="requestChannel" reply-channel="responseChannel" exchange-name="${exchange}" routing-key-expression="${routing}"/>
<int-amqp:inbound-gateway request-channel="inboundRequest"
queue-names="${queue}" connection-factory="rabbitConnectionFactory"
reply-channel="inboundResponse" message-converter="compositeMessageConverter"/>
是否可以将它们转换为java注释或类实现(bean等)?
其他:我目前正在使用spring boot
+ spring integration
。

如果你看一下Spring Integration Java DSL,那就太棒了。
它提供了一些流利的AMQP:
@Bean
public IntegrationFlow amqpFlow() {
return IntegrationFlows.from(Amqp.inboundGateway(this.rabbitConnectionFactory, queue()))
.transform("hello "::concat)
.transform(String.class, String::toUpperCase)
.get();
}
@Bean
public IntegrationFlow amqpOutboundFlow() {
return IntegrationFlows.from(Amqp.channel("amqpOutboundInput", this.rabbitConnectionFactory))
.handle(Amqp.outboundAdapter(this.amqpTemplate).routingKeyExpression("headers.routingKey"))
.get();
}
从注释的角度来看,你应该直接使用Spring Integration中的类来配置这样的东西:
@Bean
public AmqpInboundGateway amqpInbound() {
AmqpInboundGateway gateway = new AmqpInboundGateway(new SimpleMessageListenerContainer(this.rabbitConnectionFactory));
gateway.setRequestChannel(inboundChanne());
return gateway;
}
@Bean
@ServiceActivator(inputChannel = "amqpOutboundChannel")
public AmqpOutboundEndpoint amqpOutbound() {
AmqpOutboundEndpoint handler = new AmqpOutboundEndpoint(this.rabbitTemplate);
handler.setOutputChannel(amqpReplyChannel());
return handler;
}
