spring-rabbit.xml 文件
1.连接工厂
1 <!-- supply vhost 连接工厂 --> 2 <rabbit:connection-factory 3 id="itemConnectionFactory" 4 addresses="${mq.addresses}" 5 virtual-host="${mq.vhostSupply}" 6 username="${mq.username}" 7 password="${mq.password}" 8 cache-mode="${mq.cacheMode}" 9 channel-cache-size="${mq.cacheSize}" 10 connection-timeout="${mq.connectionTimeout}" 11 />
MQ的配置
1 # RabbitMQ 2 mq.host=${filter.mq.host} 3 mq.port=${filter.mq.port} 4 mq.addresses=${filter.mq.addresses} 5 mq.username=${filter.mq.username} 6 mq.password=${filter.mq.password} 7 mq.vhostSupply=${filter.mq.vhostSupply} 8 mq.cacheMode=${filter.mq.cacheMode} 9 mq.cacheSize=${filter.mq.cacheSize} 10 mq.connectionTimeout=${filter.mq.connectionTimeout} 11 mq.requestedHeartbeat=${filter.mq.requestedHeartbeat} 12 13 14 # RabbitMQ 15 filter.mq.host= 16 filter.mq.port= 17 filter.mq.addresses=127.0.0.1:5672 18 filter.mq.username=dev 19 filter.mq.password=U69o3NGHtZAmfLX5dQGW 20 filter.mq.vhostSupply=supply 21 filter.mq.cacheMode=CHANNEL 22 filter.mq.cacheSize=10 23 filter.mq.connectionTimeout=3000 24 filter.mq.requestedHeartbeat=
2.vhost 管理契
1 <!-- item vhost 管理器 --> 2 <rabbit:admin id="itemAdmin" connection-factory="itemConnectionFactory"/>
3.exchange
1 <rabbit:topic-exchange name="exchange.item.add.Original" declared-by="itemAdmin" auto-declare="true" auto-delete="false" durable="true"> 2 <rabbit:exchange-arguments> 3 </rabbit:exchange-arguments> 4 <rabbit:bindings> 5 <rabbit:binding pattern="soa.item.originalItem.created" queue="soa.item.originalItem.created.queue" /> 6 </rabbit:bindings> 7 </rabbit:topic-exchange>
4.queue
1 <rabbit:queue name="soa.item.originalItem.created.queue" declared-by="itemAdmin" auto-declare="true" auto-delete="false" durable="true" exclusive="false"> 2 <rabbit:queue-arguments> 3 <entry key="x-max-length" value="1000000" value-type="java.lang.Long"/> 4 <entry key="x-max-length-bytes" value="300485760" value-type="java.lang.Long"/> 5 </rabbit:queue-arguments> 6 </rabbit:queue>
5.template
1 <!-- JSON 消息转换器 --> 2 <bean id="jsonMessageConvertor" class="com.lcb.soa.misc.common.mq.FastJsonMessageConverter"/> 3 4 <rabbit:template id="itemEventTemplate" connection-factory="itemConnectionFactory" 5 exchange="exchange.item.add.Original" message-converter="jsonMessageConvertor"/> 6 7 <bean id="originalItemEventMqSender" class="com.lcb.soa.misc.common.mq.MQSender" p:template-ref="itemEventTemplate"/>
6.消息发送
1 @Resource(name = "originalItemEventMqSender") 2 private MQSender originalItemEventMqSender; 3 4 originalItemEventMqSender.sendAsync("soa.item.originalItem.created", addOriginalItemNotify);
