rabbitmq和spring 多点连接

1、配置rq连接信息（rq.properties）

rb.host.batch=192.168.1.1:5672,192.168.1.2:5672

2、获取配置文件值并处理生成Address[]

private static Address[] splitAddress(String hostAddress) {
        String[] hostArray = hostAddress.split(",");
        Address[] addArray = new Address[hostArray.length];
        for (int i = 0; i < hostArray.length; i++) {
            addArray[i] = new Address(hostArray[i].split(":")[0], Integer.parseInt(hostArray[i].split(":")[1]));
        }
        return addArray;
    }

3、创建连接、channel、queue

//address数组
public static void conRabbitMQ(Address[] addresses) {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setUsername("guest");
        factory.setPassword("guest");
        try {
            Connection connection=factory.newConnection(addresses);

            Channel channel= connection.createChannel();

           channel.queueDeclare("queueName",true,false,false,null);
           channel.queueBind("queueName","exchangeName","queueName");
        } catch (IOException e) {
            logger.error(e.getMessage(), e);
            return null;
        } catch (Exception e) {
            logger.error(e.getMessage(), e);
            return null;
        }
    }

4、总结

使用ConnectionFactory的newConnection(Address[] addrs) 方法创建连接，支持多个host地址，程序运行中通过connection.isOpen()来判断当前mq服务是否正常，如果值为false，会使用addrs数组中其他的host地址创建连接，重新创建连接需要创建connection和channel，channel用于发送和接收消息。
