简单使用
simple模式
- 创建队列
@Configuration
public class RabbitMQConfig {
@Bean
public Queue queue(){
return new Queue("queue",true);
}
}
- 创建消费者以及生产者
@Service
@Slf4j
public class MQReceiver {
@RabbitListener(queues = "queue")
public void receive(Object msg){
log.info("接受消息:"+msg);
}
}
@Service
@Slf4j
public class MQSender {
@Autowired
private RabbitTemplate rabbitTemplate;
public void send(Object msg){
log.info("发送消息:"+msg);
rabbitTemplate.convertAndSend("queue",msg);
}
}
- 测试
@Controller
public class UserController {
@Autowired
private MQSender mqSender;
/**
* 测试发送mq消息
*/
@RequestMapping("/mq")
@ResponseBody
public void mq(){
mqSender.send("hello");
}
结果:
发送消息:hello
接受消息:(Body:'hello' MessageProperties [headers={}, contentType=text/plain, ....)
fanout模式
简介
特点：Fanout—发布与订阅模式，是一种广播机制，它是没有路由key的模式。
- 创建队列以及交换机并将其绑定
@Configuration
public class RabbitMQConfig {
private static final String QUEUE01="queue_fanout01";
private static final String QUEUE02="queue_fanout02";
private static final String EXCHANGE="fanoutExchange";
@Bean
public Queue queue01(){
return new Queue(QUEUE01);
}
@Bean
public Queue queue02(){
return new Queue(QUEUE02);
}
@Bean
public FanoutExchange fanoutExchange(){
return new FanoutExchange(EXCHANGE);
}
@Bean
public Binding binding01(){
return BindingBuilder.bind(queue01()).to(fanoutExchange());
}
@Bean
public Binding binding02(){
return BindingBuilder.bind(queue02()).to(fanoutExchange());
}
}
- 创建消费者以及生产者
@Service
@Slf4j
public class MQSender {
@Autowired
private RabbitTemplate rabbitTemplate;
public void send(Object msg){
log.info("发送消息:"+msg);
rabbitTemplate.convertAndSend("fanoutExchange","",msg);
}
}
@Service
@Slf4j
public class MQReceiver {
@RabbitListener(queues = "queue_fanout01")
public void receive01(Object msg){
log.info("QUEUE01接受消息:"+msg);
}
@RabbitListener(queues = "queue_fanout02")
public void receive02(Object msg){
log.info("QUEUE02接受消息:"+msg);
}
}
- 测试
@Controller
public class UserController {
/**
* fanout测试
*/
@RequestMapping("/mq/fanout")
@ResponseBody
public void fanout(){
mqSender.send("hello");
}
}
结果:
QUEUE02接受消息:(Body:'hello' MessageProperties [headers={}, contentType=text/plain, contentEncoding=UTF-8, contentLength=0, receivedDeliveryMode=PERSISTENT, priority=0, redelivered=false, receivedExchange=fanoutExchange, receivedRoutingKey=, deliveryTag=1, consumerTag=amq.ctag-Dvd0kyyFky5PAMwSdonsFA, consumerQueue=queue_fanout02])
QUEUE01接受消息:(Body:'hello' MessageProperties [headers={}, contentType=text/plain, contentEncoding=UTF-8, contentLength=0, receivedDeliveryMode=PERSISTENT, priority=0, redelivered=false, receivedExchange=fanoutExchange, receivedRoutingKey=, deliveryTag=1, consumerTag=amq.ctag-fLIDTnvOimVXaxMykL1OXA, consumerQueue=queue_fanout01])
direct模式
简介
Direct模式是fanout模式上的一种叠加，增加了路由RoutingKey的模式。
- 创建队列以及交换机并将其绑定
@Configuration
public class RabbitMQConfig {
private static final String QUEUE01="queue_direct01";
private static final String QUEUE02="queue_direct02";
private static final String EXCHANGE="directExchange";
private static final String ROUTINGKEY01="queue.red";
private static final String ROUTINGKEY02="queue.green";
@Bean
public Queue queue01(){
return new Queue(QUEUE01);
}
@Bean
public Queue queue02(){
return new Queue(QUEUE02);
}
@Bean
public DirectExchange directExchange(){
return new DirectExchange(EXCHANGE);
}
@Bean
public Binding binding01(){
return BindingBuilder.bind(queue01()).to(directExchange()).with(ROUTINGKEY01);
}
@Bean
public Binding binding02(){
return BindingBuilder.bind(queue02()).to((directExchange())).with(ROUTINGKEY02);
}
}
- 创建消费者以及生产者
@Service
@Slf4j
public class MQSender {
public void send01(Object msg){
log.info("发送消息:"+msg);
rabbitTemplate.convertAndSend("directExchange","queue.red",msg);
}
public void send02(Object msg){
log.info("发送消息:"+msg);
rabbitTemplate.convertAndSend("directExchange","queue.green",msg);
}
}
@Service
@Slf4j
public class MQReceiver {
@RabbitListener(queues = "queue_direct01")
public void receive03(Object msg){
log.info("QUEUE01接受消息:"+msg);
}
@RabbitListener(queues = "queue_direct02")
public void receive04(Object msg){
log.info("QUEUE02接受消息:"+msg);
}
}
- 测试
@Controller
public class UserController {
@RequestMapping("/mq/direct01")
@ResponseBody
public void direct01(){
mqSender.send01("hello,red");
}
@RequestMapping("/mq/direct02")
@ResponseBody
public void direct02(){
mqSender.send02("hello,green");
}
}
结果:
发送消息:hello,red
QUEUE01接受消息:(Body:'hello,red' MessageProperties [headers={}, contentType=text/plain, contentEncoding=UTF-8, contentLength=0, receivedDeliveryMode=PERSISTENT, priority=0, redelivered=false, receivedExchange=directExchange, receivedRoutingKey=queue.red, deliveryTag=1, consumerTag=amq.ctag-1SllPzAeuub27hll8OZgxQ, consumerQueue=queue_direct01])
发送消息:hello,green
QUEUE02接受消息:(Body:'hello,green' MessageProperties [headers={}, contentType=text/plain, contentEncoding=UTF-8, contentLength=0, receivedDeliveryMode=PERSISTENT, priority=0, redelivered=false, receivedExchange=directExchange, receivedRoutingKey=queue.green, deliveryTag=1, consumerTag=amq.ctag-O24J9QkBtYLy4rnhisUbYA, consumerQueue=queue_direct02])
topic模式(direct模式的延伸)
简介
Topic模式是direct模式上的一种叠加，增加了模糊路由RoutingKey的模式。
'*':只能匹配一个词
'#':匹配0个或者多个词
- 创建队列以及交换机并将其绑定
@Configuration
public class RabbitMQConfig {
private static final String QUEUE01="queue_topic01";
private static final String QUEUE02="queue_topci02";
private static final String EXCHANGE="topicExchange";
private static final String ROUTINGKEY01="#.queue.#";
private static final String ROUTINGKEY02="*.queue.#";
@Bean
public Queue queue01(){
return new Queue(QUEUE01);
}
@Bean
public Queue queue02(){
return new Queue(QUEUE02);
}
@Bean
public TopicExchange directExchange(){
return new TopicExchange(EXCHANGE);
}
@Bean
public Binding binding01(){
return BindingBuilder.bind(queue01()).to(directExchange()).with(ROUTINGKEY01);
}
@Bean
public Binding binding02(){
return BindingBuilder.bind(queue02()).to((directExchange())).with(ROUTINGKEY02);
}
}
- 创建消费者以及生产者
@Service
@Slf4j
public class MQSender {
public void send03(Object msg){
log.info("发送消息(queue01接受):"+msg);
rabbitTemplate.convertAndSend("topicExchange","queue.red.message",msg);
}
public void send04(Object msg){
log.info("发送消息(queue01和02接受):"+msg);
rabbitTemplate.convertAndSend("topicExchange","message.queue.abc",msg);
}
}
@Service
@Slf4j
public class MQSender {
@RabbitListener(queues = "queue_topic01")
public void receive05(Object msg){
log.info("QUEUE01接受消息:"+msg);
}
@RabbitListener(queues = "queue_topic02")
public void receive06(Object msg){
log.info("QUEUE02接受消息:"+msg);
}
}
- 测试
@Controller
public class UserController {
@RequestMapping("/mq/topic01")
@ResponseBody
public void topic01(){
mqSender.send03("hello,red");
}
@RequestMapping("/mq/topic02")
@ResponseBody
public void topic02(){
mqSender.send04("hello,green");
}
}
结果：
发送消息(queue01接受):hello,red
QUEUE01接受消息:(Body:'hello,red' MessageProperties [headers={}, contentType=text/plain, contentEncoding=UTF-8, contentLength=0, receivedDeliveryMode=PERSISTENT, priority=0, redelivered=false, receivedExchange=topicExchange, receivedRoutingKey=queue.red.message, deliveryTag=1, consumerTag=amq.ctag--VsmPOb3T_u2mMK88qJJtA, consumerQueue=queue_topic01])
发送消息(queue01和02接受):hello,green
