Java实现rabbitMQ向MQ里推送消息

配置文件application.properties里配置rabbitMQ的ip和端口，如果没有配置username和password，就是mq安装时默认的用户名密码：

spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.virtual-host=/

业务代码：

    public void send(String msg, ExchangeEnum exchangeEnum, QueueEnum queueEnum, Class msg_class) throws Exception {
        //绑定交换机和队列
        this.bindExchangeAndQueue(exchangeEnum, queueEnum);
//        Message message = MessageBuilder.withBody(new ObjectMapper().writeValueAsBytes(msg)).build();
        Object parseObject = JSONObject.parseObject(msg, msg_class);
        //推送消息
        rabbitTemplate.convertAndSend(exchangeEnum.getName(), queueEnum.getName(), parseObject);
    }

    /**
     * 绑定 队列与交换机
     * 
     * @param exchangeEnum
     * @param queueEnum
     */
    private void bindExchangeAndQueue(ExchangeEnum exchangeEnum, QueueEnum queueEnum) {

        amqpAdmin.declareBinding(new Binding(queueEnum.getName(), Binding.DestinationType.QUEUE, exchangeEnum.getName(),
                queueEnum.getName(), null));
    }
