RabbitMq安装并与SpringBoot整合
rabbitMQ在docker中的安装
在docker中依次执行以下指令
docker search rabbitmq
docker pull rabbitmq
docker run -d --hostname myrabbitmq -P rabbitmq:3-management

便在docker中安装好了rabbitmq
SpringBoot整合RabbitMQ
pom.xml中加入的依赖如下
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>junit</groupId>

</dependencies>
在application.properties中加入rabbitmq的配置
spring.rabbitmq.host=192.168.2.104
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.port=32771
测试Direct
在启动类父文件夹下新建config包，其下新建RabbitDirectConfig.java
@Configuration
public class RabbitDirectConfig {
public final static String DIRECTNAME="xiaoliu-direct";
@Bean
Queue queue(){
return new Queue("hello.xiaoliu");
}
@Bean
DirectExchange directExchange(){
return new DirectExchange(DIRECTNAME,true,false);
}
@Bean
Binding binding(){
return BindingBuilder.bind(queue()).to(directExchange()).with("direct");
}
}
在启动类父文件夹下新建receiver包，其下新建DirectReceiver.java
@Component
public class DirectReceiver {
@RabbitListener(queues = "hello.xiaoliu")
public void handler1(String msg){
System.out.println("handler1>>>"+msg);
}
}
在测试类中添加测试方法
@RunWith(SpringRunner.class)
@SpringBootTest
public class RabbitmqApplicationTests {
@Autowired
RabbitTemplate rabbitTemplate;
@Test
public void contextLoads() {
rabbitTemplate.convertAndSend("hello.xiaoliu","hello xiaoliu!hahaha");
}
}
测试Fanout
在config包下新建RabbitFanoutConfig.java
@Configuration
public class RabbitFanoutConfig {

@Bean
Queue queueOne(){
return new Queue("queue-one");
}
@Bean
Queue queueTwo(){
return new Queue("queue-two");
}
@Bean
FanoutExchange fanoutExchange(){
return new FanoutExchange(FANOUTNAME,true,false);
}
@Bean
Binding bindingOne(){
return BindingBuilder.bind(queueOne()).to(fanoutExchange());
}
@Bean
Binding bindingTwo(){
return BindingBuilder.bind(queueTwo()).to(fanoutExchange());
}
}
在receiver包下新建FanoutReceiver.java
@Component
public class FanoutReceiver {
@RabbitListener(queues = "queue-one")
public void handler1(String msg){
System.out.println("FanoutReceiver:handler1:"+msg);
}
@RabbitListener(queues = "queue-two")
public void handler2(String msg){
System.out.println("FanoutReceiver:handler2:"+msg);
}
}
在测试类中添加测试方法
@Test
public void test1(){
rabbitTemplate.convertAndSend(RabbitFanoutConfig.FANOUTNAME,null ,"hello fanout!" );
}
测试Header
在config包下新建RabbitHeaderConfig.java
@Configuration
public class RabbitHeaderConfig {
public static final String HEADERNAME="xiaoliu-header";
@Bean
HeadersExchange headersExchange(){
return new HeadersExchange(HEADERNAME,true,false);
}
@Bean
Queue queueName(){
return new Queue("name-queue");
}
@Bean
Queue queueAge(){
return new Queue("age-queue");
}
@Bean
Binding bindingName(){
Map<String,Object> map = new HashMap<>();
map.put("name","xiaoliu" );
return BindingBuilder.bind(queueName()).to(headersExchange()).whereAny(map).match();
}
@Bean
Binding bindingAge(){
return BindingBuilder.bind(queueAge()).to(headersExchange()).where("age").exists();
}
}
在receiver包下新建HeaderReceiver.java
@Component
public class HeaderReceiver {
@RabbitListener(queues = "name-queue")
public void handler1(byte[] msg){
System.out.println("HeaderReceiver:handler1:"+new String(msg,0,msg.length));
}
@RabbitListener(queues = "age-queue")
public void handler2(byte[] msg){
System.out.println("HeaderReceiver:handler2:"+new String(msg,0,msg.length));
}
}
在测试类中添加测试方法
@Test
public void test2(){
rabbitTemplate.convertAndSend(RabbitTopicConfig.TOPICNAME,"xiaomi.news" ,"小米新闻" );
rabbitTemplate.convertAndSend(RabbitTopicConfig.TOPICNAME,"vivo.phone" ,"vivo手机" );
rabbitTemplate.convertAndSend(RabbitTopicConfig.TOPICNAME,"huawei.phone" ,"华为手机" );
}
测试Topic
在config包下新建RabbitTopicConfig.java
@Configuration
public class RabbitTopicConfig {
public static final String TOPICNAME="xiaoliu-topic";
@Bean
TopicExchange topicExchange(){
return new TopicExchange(TOPICNAME,true,false);
}
@Bean
Queue xiaomi(){
return new Queue("xiaomi");
}
@Bean
Queue huawei(){
return new Queue("huawei");
}
@Bean
Queue phone(){
return new Queue("phone");
}
@Bean
Binding xiaomiBinding(){
return BindingBuilder.bind(xiaomi()).to(topicExchange()).with("xiaomi.#");
}
@Bean
Binding huaweiBinding(){

System.out.println("TopicReceiver:handler2:"+msg);
}
@RabbitListener(queues = "phone")
public void handler3(String msg){
System.out.println("TopicReceiver:handler3:"+msg);
}
}
在测试类中添加测试方法
@Test
public void test3(){
Message nameMsg= MessageBuilder.withBody("hello xiaoliu!".getBytes()).setHeader("name","xiaoliu" ).build();
Message ageMsg= MessageBuilder.withBody("hello 99!".getBytes()).setHeader("age","99" ).build();
rabbitTemplate.send(RabbitHeaderConfig.HEADERNAME,null,ageMsg);
rabbitTemplate.send(RabbitHeaderConfig.HEADERNAME,null,nameMsg);
}
