@Autowired
private IndexService indexService;

@ResponseBody
@RequestMapping(value="/direct")
public void direct(){
	log.info("[rabbitmq][direct][start]");
	indexService.sendDirect();
	log.info("[rabbitmq][direct][end]");
}

@ResponseBody
@RequestMapping(value="/fanout")
public void fanout(){
	log.info("[rabbitmq][fanout][start]");
	indexService.sendFanout();
	log.info("[rabbitmq][fanout][end]");
}

service(IndexService):

@Resource(name = "direct-template")
private RabbitTemplate templateDirect;
@Resource(name = "fanout-template")
private RabbitTemplate fanoutDirect;

public void sendDirect(){
	Message<String> message = new Message<>();
	message.setAction("DIRECT_TEST");
	message.setData("DIRECT");
	log.info("Message:"+message.getData());
	templateDirect.convertAndSend(message);
}

public void sendFanout(){
	Message<String> message = new Message<>();
	message.setAction("FANOUT_TEST");
	message.setData("FANOUT");
	log.info("Message:"+message.getData());
	fanoutDirect.convertAndSend(message);
}

消费者获取mq并处理：
1.direct 方式

<bean id="directListener" class="com.calron.rabbitmq.listener.DirectListener" />
<rabbit:direct-exchange name="directExchange"
	auto-declare="true" auto-delete="false" durable="true" declared-by="mqAdmin">
	<rabbit:bindings>
		<rabbit:binding queue="directQueue" key="directRoutekey" />
	</rabbit:bindings>
</rabbit:direct-exchange>
<rabbit:queue name="directQueue"
	auto-declare="true" auto-delete="false"
	durable="true" declared-by="mqAdmin" />	

<rabbit:template id="direct-template"
	connection-factory="mqConnectionFactory"
	queue="directQueue"
	exchange="directExchange"
	routing-key="directRoutekey"
	message-converter="mqMessageConvertor" />		
	
<rabbit:listener-container connection-factory="mqConnectionFactory" message-converter="mqMessageConvertor">
	<rabbit:listener ref="directListener" method="accept"
		response-exchange="directExchange"
		response-routing-key="directRoutekey"
		queue-names="directQueue" />
</rabbit:listener-container>

DirectListener:

@Override
public void accept(String messageContent) throws Throwable {
	log.info("direct listener");
}

2.fanout方式

<bean id="fanoutListener1" class="com.calron.rabbitmq.listener.FanoutListener1" />
<bean id="fanoutListener2" class="com.calron.rabbitmq.listener.FanoutListener2" />
<rabbit:fanout-exchange name="fanoutExchange"
	auto-declare="true" auto-delete="false" durable="true" declared-by="mqAdmin">
	<rabbit:bindings>
		<rabbit:binding queue="fanoutQueue1"/>
		<rabbit:binding queue="fanoutQueue2"/>
	</rabbit:bindings>
</rabbit:fanout-exchange>
<rabbit:queue name="fanoutQueue1"
	auto-declare="true" auto-delete="false"
	durable="true" declared-by="mqAdmin" />	
<rabbit:queue name="fanoutQueue2"
	auto-declare="true" auto-delete="false"
	durable="true" declared-by="mqAdmin" />	

<rabbit:template id="fanout-template"
	connection-factory="mqConnectionFactory"
	queue="fanoutQueue"
	exchange="fanoutExchange"
	routing-key="fanoutRoutekey"
	message-converter="mqMessageConvertor" />		
	
<rabbit:listener-container connection-factory="mqConnectionFactory" message-converter="mqMessageConvertor">
	<rabbit:listener ref="fanoutListener1" method="accept"
		queue-names="fanoutQueue1" />
	<rabbit:listener ref="fanoutListener2" method="accept"
		queue-names="fanoutQueue2" />	
</rabbit:listener-container>

FanoutListener1：

@Override
public void accept(String messageContent) throws Throwable {
	log.info("fanout listener11111111111111");
}

FanoutListener2：

@Override
public void accept(String messageContent) throws Throwable {
	log.info("fanout listener222222222222222");
}

运行代码，访问链接，查看结果。
访问/direct

[com.controller.IndexController]-[INFO] [rabbitmq][direct][start]
[com.service.IndexService]-[INFO] Message:DIRECT
[com.controller.IndexController]-[INFO] [rabbitmq][direct][end]
[com.listener.DirectListener]-[INFO] direct listener

访问/fanout

[com.controller.IndexController]-[INFO] [rabbitmq][fanout][start]
[com.service.IndexService]-[INFO] Message:FANOUT
[com.controller.IndexController]-[INFO] [rabbitmq][fanout][end]
[com.listener.FanoutListener2]-[INFO] fanout listener222222222222222
[com.listener.FanoutListener1]-[INFO] fanout listener11111111111111
