参考:http://docs.spring.io/spring-amqp/docs/1.5.0.BUILD-SNAPSHOT/reference/html/_reference.html#containerAttributes
配置：
<description>RabbitMQ示例 接收消息 配置</description>
<!--属性文件 -->
<context:property-placeholder location="classpath*:demo.properties" />
<!-- 基础配置，注解声明，注解扫描路径等 -->
<import resource="classpath*:/applicationContext-base.xml" />
<!--引入基础配置 -->
<import resource="classpath*:/applicationContext-rabbitmq.xml" />
<!-- auto-delete="true",在监听器退出时，声明的队列将会被删除;exclusive="true",排他锁，声明的队列只能被当前对象使用 -->
<rabbit:queue id="queue.test.1" name="queue.test.1"
auto-declare="true" declared-by="rabbitAdmin" auto-delete="false"
exclusive="false" durable="true" />
<!-- -->
<rabbit:queue id="queue.test.2" name="queue.test.2"

<!-- -->
<rabbit:queue id="queue.test.3" name="queue.test.3"
auto-declare="true" declared-by="rabbitAdmin" auto-delete="false"
exclusive="false" durable="true" />
<!-- 接收消息监听器 -->
<!-- acknowledge="auto",接收到消息后，服务端会直接删掉，不管消息在客户端有没有处理成功;acknowledge="manual",
服务端会在客户端处理完毕后，反馈处理成功消息后删掉消息 -->
<!-- 初始消费者线程数 concurrency="3" -->
<!-- 预取数量（一次从RabbitMQ Server上取到的数据数量），prefetch="10" -->
<rabbit:listener-container id="listner.test.1"
error-handler="" acknowledge="auto" concurrency="3" transaction-size="10"
prefetch="10" max-concurrency="5" auto-startup="true" advice-chain="adviceChain"
auto-declare="true" channel-transacted="true" connection-factory="rabbitConnectionFactory">
<rabbit:listener queues="queue.test.1" ref="rabbitmqReceiverTest"

import org.springframework.stereotype.Service;
import cn.com.easy.utils.FastJSONUtils;
/**

@Service
public class RabbitmqReceiverTest {
@SuppressWarnings("resource")
public static void main(String[] args) {
new ClassPathXmlApplicationContext("/applicationContext-rabbitmq-receive-demo.xml");
}
/**
public void handTest1Msg(Object o) {
System.out.println("Test1 msg:" + FastJSONUtils.toJsonString(o));

/**

}三，发送消息
<description>RabbitMQ示例 发送消息配置</description>
<!--属性文件 -->
<context:property-placeholder location="classpath*:demo.properties" />
<!-- 基础配置，注解声明，注解扫描路径等 -->
<import resource="classpath*:/applicationContext-base.xml" />
<!--引入基础配置 -->
<import resource="classpath*:/applicationContext-rabbitmq.xml" />
<!-- auto-delete="true",在监听器退出时，声明的队列将会被删除;exclusive="true",排他锁，声明的队列只能被当前对象使用 -->
<rabbit:queue id="queue.test.1" name="queue.test.1"
auto-declare="true" declared-by="rabbitAdmin" auto-delete="false"
exclusive="false" durable="true" />
<!-- -->
<rabbit:queue id="queue.test.2" name="queue.test.2"
auto-declare="true" declared-by="rabbitAdmin" auto-delete="false"
exclusive="false" durable="true" />
<!-- -->
<rabbit:queue id="queue.test.3" name="queue.test.3"
auto-declare="true" declared-by="rabbitAdmin" auto-delete="false"
exclusive="false" durable="true" />
<!-- direct 交换器 ,auto-delete="true"时，当声明Exchange的连接断开时，Exchange会被删除掉 -->
<rabbit:direct-exchange id="exchange.direct"
auto-declare="true" name="exchange.direct" auto-delete="false"
durable="true" declared-by="rabbitAdmin">
<rabbit:bindings>
<rabbit:binding key="queue.test.1" queue="queue.test.1" />
<rabbit:binding key="queue.test.2" queue="queue.test.2" />
<rabbit:binding key="queue.test.3" queue="queue.test.3" />
</rabbit:bindings>
</rabbit:direct-exchange>
<!-- topic 交换器 ,auto-delete="true"时，当声明Exchange的连接断开时，Exchange会被删除掉 -->
<rabbit:topic-exchange id="exchange.topic"
auto-declare="true" name="exchange.topic" auto-delete="false" durable="true"
declared-by="rabbitAdmin">
<rabbit:bindings>
<rabbit:binding pattern="#.1" queue="queue.test.1"
exchange="" />
<rabbit:binding pattern="queue.*.2" queue="queue.test.2"
exchange="" />
<rabbit:binding pattern="queue.test.3" queue="queue.test.3"
exchange="" />
</rabbit:bindings>
</rabbit:topic-exchange>
<!-- fanout 交换器 ,auto-delete="true"时，当声明Exchange的连接断开时，Exchange会被删除掉 -->
<rabbit:fanout-exchange id="exchange.fanout"
auto-declare="true" name="exchange.fanout" auto-delete="false"
durable="true" declared-by="rabbitAdmin">
<rabbit:bindings>
<rabbit:binding queue="queue.test.1" exchange="" />
<rabbit:binding queue="queue.test.2" exchange="" />
<rabbit:binding queue="queue.test.3" exchange="" />
</rabbit:bindings>
</rabbit:fanout-exchange>注意：
1、队列名称不能以 "AMP"开头，队列名以"AMP"开头的队列将不会被创建，这是在Spring-rabbit中控制的;
2、发送的对象必须继承 序列化接口Serializable 或者 String类型 或者 byte[]数组,否者对象不会被发送，而会发送一个空的字符“”；
Spring-rabbit源码对发送对象的一段处理,object即为要发送的对象
/**
@Override
protected Message createMessage(Object object, MessageProperties messageProperties) throws MessageConversionException {
byte[] bytes = null;
if (object instanceof byte[]) {
bytes = (byte[]) object;
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_BYTES);
}
else if (object instanceof String) {
try {
bytes = ((String) object).getBytes(this.defaultCharset);
}
catch (UnsupportedEncodingException e) {
throw new MessageConversionException(
"failed to convert to Message content", e);
}
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
messageProperties.setContentEncoding(this.defaultCharset);
}
else if (object instanceof Serializable) {
try {
bytes = SerializationUtils.serialize(object);
} catch (IllegalArgumentException e) {
throw new MessageConversionException(
"failed to convert to serialized Message content", e);
}
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_SERIALIZED_OBJECT);
}
if (bytes != null) {
messageProperties.setContentLength(bytes.length);
}
return new Message(bytes, messageProperties);
}
