spring整合RabbitMQ

今天就来康康spring怎么整合RabbitMQ

　　注意一点，在发送消息的时候对template进行配置mandatory=true保证监听有效

　 生产端还可以配置其他属性，比如发送重试，超时时间、次数、间隔等

消费端核心配置

首先配置手工确认模式，用于ACK的手工处理，这样我们可以保证消息的可靠性送达，或者在消费端消费失败的时候可以做到重回队列、根据业务记录日志等处理

可以设置消费端的监听个数和最大个数，用于控制消费端的并发情况

@RabbitListener注解的使用

消费端监听@RabbitListener注解，这个对于在实际工作中非常的好用

@RabbitListener是一个组合注解，里面可以注

解配置（@QueueBinding、@Queue、@Exchange）直接通过这个组合注解一次性搞定消费端交换机、队列、绑定、路由、并且配置监听功能等

注：由于类配置写在代码里非常不友好，所以强烈建议大家使用配置文件配置

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

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：
