RabbitMQ 几种工作模式---通用工具类，配置类

 

转自图灵-白起

 

几种工作模式供用到两个jar：

 　　　　<dependency>
            <groupId>com.rabbitmq</groupId>
            <artifactId>amqp-client</artifactId>
            <version>5.3.0</version>
        </dependency>
        <dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
            <version>2.8.5</version>
        </dependency>

 

获取RabbitMQ连接类：

package com..utils;

import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class RabbitUtils {
    private static ConnectionFactory connectionFactory = new ConnectionFactory();
    static {
        connectionFactory.setHost("127.0.0.1");
        connectionFactory.setPort(5672);//5672是RabbitMQ的默认端口号
//        connectionFactory.setUsername("guest");
//        connectionFactory.setPassword("guest");
        connectionFactory.setUsername("admin");
        connectionFactory.setPassword("admin");
//        connectionFactory.setVirtualHost("/admin");
    }
    public static Connection getConnection(){
        Connection conn = null;
        try {
            conn = connectionFactory.newConnection();
            return conn;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}

 

demo中用到的 队列 和 交换机 声明类：

package com.wondersgroup.utils;

public class RabbitConstant {
    //队列
    public static final String QUEUE_SMS = "sms";
    public static final String QUEUE_SINA = "sina";
    public static final String QUEUE_BAIDU = "baidu";
    public static final String EXCHANGE_WEATHER = "weather";
    public static final String QUEUE_HELLOWORLD = "helloworld";
    //交换机
    public static final String EXCHANGE_WEATHER_TOPIC = "weather_topic";
    public static final String EXCHANGE_WEATHER_ROUTING = "weather_routing";
}
