RabbitMq整合SpringBoot使用方法

整合方法详见：

整合好之后，打开 http://localhost:15672，开启rabbitMq。

使用方法：

1.定义一个Config类，用于定义Queue和Exchanger,然后将这2个类绑定起来，用于发送文件。

@Configuration
public class FanoutRabbitConfig {
    /**
     * 1.定义一个Queue，然后定义一个Exchange，绑定Queue和Exchange，即可实现发送、接收
     * 2.接收类需要定义一个Listener，用于监听发送的相应消息
     * @return
     */

    @Bean
    public Queue AMessage() {
        return new Queue("fanout.A");
    }

    @Bean
    public Queue BMessage() {
        return new Queue("fanout.B");
    }

    @Bean
    public Queue CMessage() {
        return new Queue("fanout.C");
    }

    @Bean
    FanoutExchange fanoutExchange() {
        return new FanoutExchange("fanoutExchange");
    }

    @Bean
    Binding bindingExchangeA(Queue AMessage,FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(AMessage).to(fanoutExchange);
    }

    @Bean
    Binding bindingExchangeB(Queue BMessage, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(BMessage).to(fanoutExchange);
    }

    @Bean
    Binding bindingExchangeC(Queue CMessage, FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(CMessage).to(fanoutExchange);
    }

}

2.定义Sender类，用于编辑报文内容，并使用AmqpTemplate的convertAndSend方法发送报文。值得注意的是：convertAndSend(“fanoutExchange”,"", context)方法中，fanoutExchange要和FanoutRabbitConfig中定义的FanoutExchange名称完全一致。

@Component
public class FanoutSender {

	@Autowired
	private AmqpTemplate rabbitTemplate;

	public void send() {
		String context = "hi, fanout msg ";
		System.out.println("Sender : " + context);
		this.rabbitTemplate.convertAndSend("fanoutExchange","", context);
	}

}

3.定义Receiver类，用与根据注册在Config中的报文名称接收报文内容。这里需要定义Listener，@RabbitListener(queues = “fanout.A”),其中，fanout.A要在Config类中定义。

@Component
@RabbitListener(queues = "fanout.A")
public class FanoutReceiverA {

    @RabbitHandler
    public void process(String message) {
        System.out.println("fanout Receiver A  : " + message);
    }

}

4.编写test类。

@RunWith(SpringRunner.class)
@SpringBootTest
public class FanoutTest {

	@Autowired
	private FanoutSender sender;

	@Test
	public void fanoutSender() throws Exception {
		sender.send();
	}
}

控制台打印如下：

Sender : hi, fanout msg
