1、POM檔案，加入依賴

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <version>1.4.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

    </properties>

                <configuration>
                    <fork>true</fork>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>
 

2、訂單實體類：Order

import java.io.Serializable;

public class Order implements Serializable {

    private static final long serialVersionUID = 7589820506567799193L;

    private String id;

    private String name;

    /**
     * 訊息ID
     */
    private String messageId;

    public Order() {

    }

    public Order(String id, String name, String messageId) {
        this.id = id;
        this.name = name;
        this.messageId = messageId;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getMessageId() {
        return messageId;
    }

    public void setMessageId(String messageId) {
        this.messageId = messageId;
    }
}
 

3、application.properties配置檔案

spring.rabbitmq.addresses=localhost:5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/
spring.rabbitmq.connection-timeout=15000

server.servlet-path=/
server.port=8001

spring.http.encoding.charset=utf-8
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8
spring.jackson.default-property-inclusion=non_null
 

4、生產者類：RabbitProvider

import com.rabbitmq.model.Order;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.support.CorrelationData;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class RabbitSender {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    // 傳送訊息方法呼叫: 構建Message訊息
    public void send(Order order) throws Exception {
        // 訊息唯一ID
        CorrelationData correlationData = new CorrelationData(order.getId());
        rabbitTemplate.convertAndSend("order-exchange", // exchange：交換機
                "order.abcd", // routing-key
                            order, // 訊息體內容
                            correlationData); // 訊息唯一ID
    }
}

5、啟動類檔案：Application

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}
