消息类

• 要实现 Serializable 接口；

package com.example.rabbitmq.springbootproducer.entity;


import java.io.Serializable;

public class Order implements Serializable{

    private String id;
    private String name;
    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;
    }
}

发送消息

package com.example.rabbitmq.springbootproducer.producer;

import com.example.rabbitmq.springbootproducer.entity.Order;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class OrderSender {

    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void send(Order order) {
        CorrelationData correlationData = new CorrelationData();
        correlationData.setId(order.getMessageID());
        rabbitTemplate.convertAndSend(
                "order-exchange",
                "order.abcd",
                order,
                correlationData); // 消息唯一ID

    }

}

测试发送

package com.example.rabbitmq.springbootproducer;

import com.example.rabbitmq.springbootproducer.entity.Order;
import com.example.rabbitmq.springbootproducer.producer.OrderSender;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.UUID;

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootProducerApplicationTests {

    @Autowired
    private OrderSender orderSender;

    @Test
    public void contextLoads() {
    }

    @Test
    public void testSend1() throws Exception{
        Order order = new Order();
        order.setId("20190409000000001");
        order.setName("测试订单1");
        order.setMessageID(System.currentTimeMillis() + "$" + UUID.randomUUID().toString());
        orderSender.send(order);
    }

}
