RabbitMQ 提供了5種常用消息模型,本文主要介紹了Springboot集成RabbitMQ并驗(yàn)證五種消息模型,具有一定的參考價(jià)值,感興趣的可以了解一下

一、添加依賴

        <!--AMQP依賴，包含RabbitMQ-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>

        <!-- 引入knife4j-spring-ui包 /doc.html-->
        <dependency>
            <groupId>com.github.xiaoymin</groupId>
            <artifactId>knife4j-spring-boot-starter</artifactId>
            <version>3.0.3</version>
        </dependency>

二、配置文件中添加RabbitMQ訪問配置

spring.rabbitmq.host=192.168.0.104
spring.rabbitmq.port=5672
spring.rabbitmq.virtual-host=/
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin123

三、消息生產(chǎn)者代碼

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

@Api(tags = "生產(chǎn)者服務(wù)")
@RestController
public class ProducerController {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    @ApiOperation(value = "基本消息模型")
    @PostMapping("/testHello")
    public String testHello() {
        rabbitTemplate.convertAndSend("hello","hello world");
        return "ok";
    }

    @ApiOperation(value = "work消息模型")
    @PostMapping("/testWork")
    public String testWork() {
        for (int i = 0; i < 10; i++) {
            rabbitTemplate.convertAndSend("work","hello work!");
        }
        return "ok";
    }

    @ApiOperation(value = "訂閱模型-Fanout 廣播模式")
    @PostMapping("/testFanout")
    public String testFanout() {
        rabbitTemplate.convertAndSend("logs","","這是日志廣播");
        return "ok";
    }

    @ApiOperation(value = "訂閱模型-Direct")
    @PostMapping("/testDirect")
    public String testDirect() {
        rabbitTemplate.convertAndSend("directs","error","error 的日志信息");
        return "ok";
    }

    @ApiOperation(value = "訂閱模型-Topic")
    @PostMapping("/testTopic")
    public String testTopic() {
        rabbitTemplate.convertAndSend("topics","user.save.findAll","user.save.findAll 的消息");
        return "ok";
    }
}

四、消息消費(fèi)者代碼

import org.springframework.amqp.rabbit.annotation.Exchange;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;


@Component
public class SpringRabbitListener {

     //基本消息模型
     @RabbitListener(queuesToDeclare = @Queue("hello"))
     public void receive(String message) {
         System.out.println("message = " + message);
     }

     //work消息模型
     @RabbitListener(queuesToDeclare = @Queue("work"))
     public void workReceive1(String message) {
         System.out.println("workReceive1 message = " + message);
     }
     //work消息模型
     @RabbitListener(queuesToDeclare = @Queue("work"))
     public void workReceive2(String message) {
         System.out.println("workReceive2 message = " + message);
     }

    //訂閱模型-Fanout 廣播模式
    @RabbitListener(bindings = @QueueBinding(value = @Queue, exchange = @Exchange(name="logs",type = "fanout")))
    public void fanoutReceive(String message) {
        System.out.println("fanoutReceive message = " + message);
    }

    //訂閱模型-Direct
    @RabbitListener(bindings ={@QueueBinding(value = @Queue(),key={"info","error"},exchange = @Exchange(type = "direct",name="directs"))})
    public void directReceive(String message) {
        System.out.println("directReceive message = " + message);
    }

    //訂閱模型-Topic
    @RabbitListener(bindings = {@QueueBinding( value = @Queue,key = {"user.*"},exchange = @Exchange(type = "topic",name = "topics"))})
    public void topicReceive1(String message) {
        System.out.println("topicReceive1 message = " + message);
    }
    //訂閱模型-Topic
    @RabbitListener(bindings = {@QueueBinding(value = @Queue,key = {"user.#"},exchange = @Exchange(type = "topic",name = "topics"))})
    public void topicReceive2(String message) {
        System.out.println("topicReceive2 message = " + message);
    }

}

五、驗(yàn)證
