SpringBoot整合AMQP（RabbitMQ）
-
添加pom依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> -
application.properties配置
spring.rabbitmq.host=***.***.***.*** spring.rabbitmq.port=5762 spring.rabbitmq.username=admin spring.rabbitmq.password=*** - 在RabbitMQ中所有的消息生产者提交的消息都会交由Exchange进行再分配，Exchange会根据不同的策略将消息分发到不同的Queue中。RabbitMQ提供了4种不同策略，分别是Direct、Fanout、Topic、Header，4种策略中前三种使用率较高
- `Direct`
> DirectExchange的路由策略是将消息队列绑定到一个DirectExchange上，但一条消息到达DirectExchange时会被转发到与该条消息routing key相同的Queue上
- DirectExchange的配置如下：/**
* @author wsyjlly
* @create 2019.07.17 - 21:33
**/
@Configuration
public class RabbitDirectConfig {
public final static String DIRECTNAME = "ysw-direct";
@Bean
Queue queue1(){
return new Queue("queue-direct1");
}
@Bean
Queue queue2(){
return new Queue("queue-direct2");
}
@Bean
Queue queue3(){
return new Queue("queue-direct3");
}
@Bean
DirectExchange directExchange(){
return new DirectExchange(DIRECTNAME,true,false);
}
@Bean
Binding binding1(){
return BindingBuilder.bind(queue1()).to(directExchange()).with("direct1");
}
@Bean
Binding binding2(){
return BindingBuilder.bind(queue2()).to(directExchange()).with("direct2");
}
} > DirectExchange和Binding两个Bean的配置可以省略掉，即如果使用DirectExchange，之配置一个Queue的实例即可
- 配置消费者/**
* @author wsyjlly
* @create 2019.07.17 - 21:42
**/
@Component
public class DirectReceiver {
Logger logger= LoggerFactory.getLogger(getClass());
@RabbitListener(queues = "queue-direct1")
public void directHandler1(String msg){
logger.info("\033[30;4m"+"queue-direct1:"+msg+"\033[0m");
}
@RabbitListener(queues = "queue-direct2")
public void directHandler2(String msg){
logger.info("\033[30;4m"+"queue-direct2:"+msg+"\033[0m");
}
@RabbitListener(queues = "queue-direct3")
public void directHandler3(String msg){
logger.info("\033[30;4m"+"queue-direct3:"+msg+"\033[0m");
}
} > 通过@RabbitListener注解指定一个方法是一个消费者方法，方法参数就是所接收的消息。
- 消息发送
> 通过注入RabbitTemplate对象来进行消息发送，在这里我通过定时任务使其自定发送，须开启定时任务，详细操作可查看<SpringBoot定时任务@Schedule>一节/**
* @author wsyjlly
* @create 2019.07.18 - 1:13
**/
@Component
public class RabbitmqSchedule {
@Autowired
RabbitTemplate rabbitTemplate;
Logger logger = LoggerFactory.getLogger(getClass());
@Scheduled(fixedDelay = 5000,initialDelay = 3000)
public void direct(){
String message = "direct-task";
logger.info("\033[30;4m"+message+"\033[0m");
rabbitTemplate.convertAndSend("ysw-direct","direct1",message);
rabbitTemplate.convertAndSend("ysw-direct","direct2",message);
rabbitTemplate.convertAndSend("queue-direct3",message);
}
}- `Fanout`
> FanoutExchange的数据交换策略是把所有到达FanoutExchange的消息转发给所有与他绑定的Queue，在这种策略中，routingkey将不起作用。
- FanoutExchange的配置方式如下：/**
* @author wsyjlly
* @create 2019.07.17 - 21:33
**/
@Configuration
public class RabbitFanoutConfig {
public final static String FANOUTNAME = "ysw-fanout";
@Bean
Queue queue4(){
return new Queue("queue-fanout1");
}
@Bean
Queue queue5(){
return new Queue("queue-fanout2");
}
@Bean
Queue queue6(){
return new Queue("queue-fanout3");
}
@Bean
FanoutExchange fanoutExchange(){
return new FanoutExchange(FANOUTNAME,true,false);
}
@Bean
Binding binding4(){
return BindingBuilder.bind(queue4()).to(fanoutExchange());
}
@Bean
Binding binding5(){
return BindingBuilder.bind(queue5()).to(fanoutExchange());
}
@Bean
Binding binding6(){
return BindingBuilder.bind(queue6()).to(fanoutExchange());
}
} - 配置消费者/**
* @author wsyjlly
* @create 2019.07.17 - 21:42
**/
@Component
public class FanoutReceiver {
Logger logger= LoggerFactory.getLogger(getClass());
@RabbitListener(queues = "queue-fanout1")
public void fanoutHandler1(String msg){
logger.info("\033[31;4m"+"queue-fanout1:"+msg+"\033[0m");
}
@RabbitListener(queues = "queue-fanout2")
public void fanoutHandler2(String msg){
logger.info("\033[31;4m"+"queue-fanout2:"+msg+"\033[0m");
}
@RabbitListener(queues = "queue-fanout3")
public void fanoutHandler3(String msg){
logger.info("\033[31;4m"+"queue-fanout3:"+msg+"\033[0m");
}
} - 消息发送/**

**/
@Component
public class RabbitmqSchedule {
@Autowired
RabbitTemplate rabbitTemplate;
Logger logger = LoggerFactory.getLogger(getClass());
Scheduled(fixedDelay = 5000,initialDelay = 4000)
public void fanout(){
String message = "fanout-task";
logger.info("\033[31;4m"+message+"\033[0m");
rabbitTemplate.convertAndSend("ysw-fanout",null,message);
}
}- `Topic`
> TopicExchange是比较复杂也比较灵活的一种路由策略，在TopicExchange中，Queue通过routingkey绑定到TopicExchange上，当消息发送到TopicExchange后，TopicExchange根据消息的routingkey将消息路由到一个或多个Queue上。
- TopicExchange配置如下：/**
* @author wsyjlly
* @create 2019.07.17 - 21:33
**/
@Configuration
public class RabbitTopicConfig {
public final static String TOPIC_NAME = "ysw-topic";
@Bean
Queue queue7(){
return new Queue("queue-topic1");
}
@Bean
Queue queue8(){
return new Queue("queue-topic2");
}
@Bean
Queue queue9(){
return new Queue("queue-topic3");
}
@Bean
TopicExchange topicExchange(){
return new TopicExchange(TOPIC_NAME,true,false);
}
@Bean
Binding binding7(){
/*

**/
return BindingBuilder.bind(queue7()).to(topicExchange()).with("#.topic1");
}
@Bean
Binding binding8(){
return BindingBuilder.bind(queue8()).to(topicExchange()).with("topic2.#");
}
@Bean

}
}- `Header`
> HeaderExchange是一种较少使用的路由策略，HeaderExchange会根据消息的Header将消息路由到不同的Queue上，这种策略也和routingkey无关。
- HeaderExchange配置如下：/**
* @author wsyjlly
* @create 2019.07.17 - 21:33
**/
@Configuration
public class RabbitHeaderConfig {
public final static String HEADER_NAME = "ysw-header";
@Bean
Queue queue10(){
return new Queue("queue-header1");
}
@Bean
Queue queue11(){
return new Queue("queue-header2");
}
@Bean
Queue queue12(){
return new Queue("queue-header3");
}
@Bean
HeadersExchange headersExchange(){
return new HeadersExchange(HEADER_NAME,true,false);
}
@Bean
Binding binding10(){
Map<String,Object> map = new HashMap<>();
map.put("age", "18");
map.put("name", "ysw");
return BindingBuilder.bind(queue10()).to(headersExchange()).whereAny(map).match();
}
@Bean
Binding binding11(){
Map<String,Object> map = new HashMap<>();
map.put("name", "ysw");
return BindingBuilder.bind(queue11()).to(headersExchange()).where("age").exists();
}
@Bean
Binding binding12(){
Map<String,Object> map = new HashMap<>();
map.put("age", "18");
map.put("name", "ysw");
return BindingBuilder.bind(queue12()).to(headersExchange()).whereAll(map).match();
}
} > Binding配置注释：whereAny表示消息的Header中只要有一个Header匹配上map中的key/value，就把该消息路由到名为“queue-header1”的Queue上；whereAll方法表示消息的所有Header都要匹配，才将消息路由到名为“queue-header2”的Queue上；where表示只要消息的header中包含age，无论age值为多少，都将消息路由到名为“queue-header2”的Queue上。
