<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.6.0</version>
</dependency>
</dependencies>
2、配置文件
server:
port: 8080
spring:
rabbitmq:
host: 192.168.131.171
port: 5672
username: jihu
password: jihu
virtual-host: /jihu
3、启动类
@SpringBootApplication
public class RabbitMQApplication {
public static void main(String[] args) {
SpringApplication.run(RabbitMQApplication.class);
}
}
5、Swagger2类
@Configuration
@EnableSwagger2
public class Swagger2 {
// http://127.0.0.1:8080/swagger-ui.html
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.jihu"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("极狐-Spring Boot中使用spring-boot-starter-amqp集成rabbitmq")
.description("测试SpringBoot整合进行各种工作模式信息的发送")
.contact("roykingw")
.version("1.0")
.build();
}
}
6、ProducerController
@RestController
public class ProducerController {
@Autowired
private RabbitTemplate rabbitTemplate;
//helloWorld 直连模式
@ApiOperation(value = "helloWorld发送接口", notes = "直接发送到队列")
@GetMapping(value = "/helloWorldSend")
public Object helloWorldSend(String message) throws AmqpException, UnsupportedEncodingException {
//设置部分请求参数
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//发消息
rabbitTemplate.send("helloWorldqueue", new Message(message.getBytes("UTF-8"), messageProperties));
return "message sended : " + message;
}
//工作队列模式
@ApiOperation(value = "workqueue发送接口", notes = "发送到所有监听该队列的消费")
@GetMapping(value = "/workqueueSend")
public Object workqueueSend(String message) throws AmqpException, UnsupportedEncodingException {
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//制造多个消息进行发送操作
for (int i = 0; i < 10; i++) {
rabbitTemplate.send("work_sb_mq_q", new Message(message.getBytes("UTF-8"), messageProperties));
}
return "message sended : " + message;
}
// pub/sub 发布订阅模式 交换机类型 fanout
@ApiOperation(value = "fanout发送接口", notes = "发送到fanoutExchange。消息将往该exchange下的所有queue转发")
@GetMapping(value = "/fanoutSend")
public Object fanoutSend(String message) throws AmqpException, UnsupportedEncodingException {
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//fanout模式只往exchange里发送消息。分发到exchange下的所有queue
rabbitTemplate.send("fanoutExchange", "", new Message(message.getBytes("UTF-8"), messageProperties));
return "message sended : " + message;
}
//routing路由工作模式 交换机类型 direct
@ApiOperation(value = "direct发送接口", notes = "发送到directExchange。exchange转发消息时，会往routingKey匹配的queue发送")
@GetMapping(value = "/directSend")
public Object routingSend(String routingKey, String message) throws AmqpException, UnsupportedEncodingException {
if (null == routingKey) {
routingKey = "china.changsha";
}
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//fanout模式只往exchange里发送消息。分发到exchange下的所有queue
rabbitTemplate.send("directExchange", routingKey, new Message(message.getBytes("UTF-8"), messageProperties));
return "message sended : routingKey >" + routingKey + ";message > " + message;
}
//topic 工作模式 交换机类型 topic
@ApiOperation(value = "topic发送接口", notes = "发送到topicExchange。exchange转发消息时，会往routingKey匹配的queue发送，*代表一个单词，#代表0个或多个单词。")
@GetMapping(value = "/topicSend")
public Object topicSend(String routingKey, String message) throws AmqpException, UnsupportedEncodingException {
if (null == routingKey) {
routingKey = "changsha.kf";
}
MessageProperties messageProperties = new MessageProperties();
messageProperties.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);
//fanout模式只往exchange里发送消息。分发到exchange下的所有queue
rabbitTemplate.send("topicExchange", routingKey, new Message(message.getBytes("UTF-8"), messageProperties));
return "message sended : routingKey >" + routingKey + ";message > " + message;
}
}
7、ConcumerReceiver
@Component
public class ConcumerReceiver {
//直连模式的多个消费者，会分到其中一个消费者进行消费。类似task模式
//通过注入RabbitContainerFactory对象，来设置一些属性，相当于task里的channel.basicQos
@RabbitListener(queues = "helloWorldqueue")
public void helloWorldReceive(String message) {
System.out.println("helloWorld模式 received message : " + message);
}
//工作队列模式
@RabbitListener(queues = "work_sb_mq_q")
public void wordQueueReceiveq1(String message) {
System.out.println("工作队列模式1 received message : " + message);
}
@RabbitListener(queues = "work_sb_mq_q")
public void wordQueueReceiveq2(String message) {
System.out.println("工作队列模式2 received message : " + message);
}
//pub/sub模式进行消息监听
@RabbitListener(queues = "fanout.q1")
public void fanoutReceiveq1(String message) {
System.out.println("发布订阅模式1received message : " + message);
}
@RabbitListener(queues = "fanout.q2")
public void fanoutReceiveq2(String message) {
System.out.println("发布订阅模式2 received message : " + message);
}
//Routing路由模式
@RabbitListener(queues = "direct_sb_mq_q1")
public void routingReceiveq1(String message) {
System.out.println("Routing路由模式routingReceiveq11111 received message : " + message);
}
@RabbitListener(queues = "direct_sb_mq_q2")
public void routingReceiveq2(String message) {
System.out.println("Routing路由模式routingReceiveq22222 received message : " + message);
}
//topic 模式
//注意这个模式会有优先匹配原则。例如发送routingKey=hunan.IT,那匹配到hunan.*(hunan.IT,hunan.eco),之后就不会再去匹配*.ITd
@RabbitListener(queues = "topic_sb_mq_q1")
public void topicReceiveq1(String message) {
System.out.println("Topic模式 topic_sb_mq_q1 received message : " + message);
}
@RabbitListener(queues = "topic_sb_mq_q2")
public void topicReceiveq2(String message) {
System.out.println("Topic模式 topic_sb_mq_q2 received message : " + message);
}
}
二、简单模式
队列配置：
@Configuration
public class HelloWorldConfig {
@Bean
public Queue setQueue() {
return new Queue("helloWorldqueue");
}
}
三、工作队列模式
@Configuration
public class WorkConfig {
//声明队列
@Bean
public Queue workQ1() {
return new Queue("work_sb_mq_q");
}
}
四、广播模式（Fanout）
@Configuration
public class FanoutConfig {
//声明队列
@Bean
public Queue fanoutQ1() {
return new Queue("fanout.q1");
}
@Bean
public Queue fanoutQ2() {
return new Queue("fanout.q2");
}
//声明exchange
@Bean
public FanoutExchange setFanoutExchange() {
return new FanoutExchange("fanoutExchange");
}
//声明Binding,exchange与queue的绑定关系
@Bean
public Binding bindQ1() {
return BindingBuilder.bind(fanoutQ1()).to(setFanoutExchange());
}
@Bean
public Binding bindQ2() {
return BindingBuilder.bind(fanoutQ2()).to(setFanoutExchange());
}
}
五、直连模式（Direct）
@Configuration
public class DirectConfig {
//声明队列
@Bean
public Queue directQ1() {
return new Queue("direct_sb_mq_q1");
}
@Bean
public Queue directQ2() {
return new Queue("direct_sb_mq_q2");
}
//声明exchange
@Bean
public DirectExchange setDirectExchange() {
return new DirectExchange("directExchange");
}
//声明binding，需要声明一个routingKey
@Bean
public Binding bindDirectBind1() {
return BindingBuilder.bind(directQ1()).to(setDirectExchange()).with("china.changsha");
}
@Bean
public Binding bindDirectBind2() {
return BindingBuilder.bind(directQ2()).to(setDirectExchange()).with("china.beijing");
}
}
六、通配符模式（Topic）
@Configuration
public class TopicConfig {
//声明队列
@Bean
public Queue topicQ1() {
return new Queue("topic_sb_mq_q1");
}
@Bean
public Queue topicQ2() {
return new Queue("topic_sb_mq_q2");
}
//声明exchange
@Bean
public TopicExchange setTopicExchange() {
return new TopicExchange("topicExchange");
}
//声明binding，需要声明一个roytingKey
@Bean
public Binding bindTopicHebei1() {
return BindingBuilder.bind(topicQ1()).to(setTopicExchange()).with("changsha.*");
}
@Bean
public Binding bindTopicHebei2() {
return BindingBuilder.bind(topicQ2()).to(setTopicExchange()).with("#.beijing");
}
}测试
我们启动上面的SpringBoot项目。
然后我们访问swagger地址：http://127.0.0.1:8080/swagger-ui.html
然后我们就可以使用swagger测试接口了。
或者可以使用postman进行测试。
