根据学习的RabbitMQ知识配了一个SpringMVC的实现。这是一个完整的工程,view的部分使用freeMarker,持久化操作是通过mybatis实现。
整个工程的目录结构如下:
src下的相关包的解释:
controller:控制器;
domain:对应数据库的操作对象类;
persistence:mybatis的持久化操作;
util:相关工具类;
msg.bean:消息类,定义及描述消息体;
msg.convert:实现如何转化消息体为可接受的消息类;
msg.process:处理器,负责接受到消息后如何处理;
msg.service:包括sender及listener的实现,用于完成发送和接受消息。
config目录存储相关配置文件。
1、配置
web.xml配置,主要配置spring及spring mvc:
<display-name>springRabbit</display-name> <!-- Spring 容器加载的配置文件 设置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext*.xml</param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <!--Spring默认刷新Log4j配置文件的间隔,单位为millisecond --> <context-param> <param-name>log4jRefreshInterval</param-name> <param-value>60000</param-value> </context-param> <!-- Spring 配置 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- Spring MVC 配置 --> <servlet> <servlet-name>springDispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:/applicationContext-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springDispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
对于springMVC的配置这里不再赘述,本文主要描述的是RabbitMQ的配置,故此处只详细描述RabbitMQ的配置:
applicationContext-mq.xml配置:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit-1.2.xsd"> <!-- common configuration start--> <!-- 连接服务配置 --> <rabbit:connection-factory id="connectionFactory" host="localhost" username="guest" password="guest" port="5672" /> <rabbit:admin connection-factory="connectionFactory" /> <!-- queue 队列声明--> <rabbit:queue id="pptv" durable="true" auto-delete="false" exclusive="false" name="pptv" /> <!-- exchange queue binging key 绑定 --> <rabbit:direct-exchange name="my-mq-exchange" durable="true" auto-delete="false" id="my-mq-exchange"> <rabbit:bindings> <rabbit:binding queue="pptv" key="pptv_key" /> </rabbit:bindings> </rabbit:direct-exchange> <bean id="jsonMessageConverter" class="com.pptv.msg.convert.JsonMessageConverter"></bean> <!-- spring template声明--> <rabbit:template exchange="my-mq-exchange" id="amqpTemplate" connection-factory="connectionFactory" message-converter="jsonMessageConverter" /> <!-- amqp template 可根据不同业务分为不同template--> <rabbit:template id="testTemplate" connection-factory="connectionFactory" message-converter="jsonMessageConverter" reply-timeout="2000" routing-key="pptv_key" exchange="my-mq-exchange" /> <!-- common configuration end--> <!-- sender start--> <!-- sender 可根据不同业务分为不同sender--> <bean id="testSender" class="com.pptv.msg.service.impl.AmqpMessageSenderImpl"> <property name="amqpTemplate" ref="testTemplate" /> </bean> <!-- sender中的一种,独立出来是为了发送添加错误code的信息 --> <bean id="errorMsgSender" class="com.pptv.msg.service.impl.AmqpMessageSenderImpl"> <property name="amqpTemplate" ref="testTemplate" /> </bean> <!-- sender service --> <bean id="testSendService" class="com.pptv.msg.service.sendservice.impl.TestMessageSendServiceImpl"> <property name="messageSender" ref="testSender" /> </bean> <!-- sender end--> <!-- processor 这里可以处理响应的业务类型--> <bean id="testMessageProcessor" class="com.pptv.msg.process.UserMessageProcessorImpl"> </bean> <!-- receiver start--> <!-- listener --> <bean id="testMessageListener" class="com.pptv.msg.service.impl.AmqpMessageListenerImpl"> <property name="messageProcessor" ref="testMessageProcessor" /> <property name="messageConverter" ref="jsonMessageConverter" /> <property name="errorMsgSender" ref="errorMsgSender" /> </bean> <!-- queue litener 观察 监听模式 当有消息到达时会通知监听在对应的队列上的监听对象--> <rabbit:listener-container connection-factory="connectionFactory" concurrency="2" channel-transacted="false" acknowledge="auto"> <rabbit:listener queues="pptv" ref="testMessageListener" method="onMessage" /> </rabbit:listener-container> <!-- receiver end--> </beans>
因为本工程吧sender和receiver的功能都融合在一起了,所以在配置中可以看到同时有sender和receiver的单独配置,以及公共的配置。单独配置其实是一样的,只需要分成两个工程,代码和配置分开就是了。可参考以下文章:http://my.oschina.net/never/blog/140368
对类及配置的具体的、详细的描述在本文就不描写了,实在是太多了,写起来可能过于详细,但是对于开发过springMVC项目的人来说,看了源码就应该能轻松搞定的。
