今天就来康康spring怎么整合RabbitMQ
消费端核心配置
@RabbitListener注解的使用
创建一个
rabbitmq-common通用模板项目
放公用实体类
package com.javaxh.rabbitmqcommon.entity;
import java.io.Serializable;
public class Order implements Serializable { private String id;
private String name; public Order() {
}
public Order(String id, String name) {
super();
this.id = id;
this.name = name;
}
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;
}
}
创建
rabbitmq-springcloud-consumer子项目

测试代码:
RabbitmqSpringcloudProducerApplicationTests
package com.javaxh.rabbitmqspringcloudproducer;
import com.javaxh.rabbitmqcommon.entity.Order;
import com.javaxh.rabbitmqspringcloudproducer.producer.RabbitSender;
import org.junit.jupiter.api.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.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map; @RunWith(SpringRunner.class)
@SpringBootTest
class RabbitmqSpringcloudProducerApplicationTests { @Autowired
private RabbitSender rabbitSender; private static SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS"); @Test
public void testSender1() throws Exception {
Map<String, Object> properties = new HashMap<>();
properties.put("number", "12345");
properties.put("send_time", simpleDateFormat.format(new Date()));
rabbitSender.send("Hello RabbitMQ For Spring Boot!", properties);
} @Test
public void testSender2() throws Exception {
Order order = new Order("001", "第一个订单");
rabbitSender.sendOrder(order);
} }
运行效果:
启动consumer项目,然后在运行测试类中的方法
运行公用模板类传送一个实体类给方法:
