springboot下使用rabbitMQ之开发配置方式(二)
springboot下使用rabbitMQ之传参及序列化(二)消息参数传递在开发中也是个坑，不论使用内置的SimpleMessageConverter还是Jackson2JsonMessageConverter均无法让Consumer接收动态参数
一.序列化的问题
首先贴出具体代码以及测试用例:
[*]消费者
@RabbitListener(queues = "text.queue")
@RabbitHandler(isDefault = true)
public void exec(@Payload Map dto, Message message, Channel channel){
// 注意，发送的消息类型必须是实现了Serializable接口的类型，消费者接口类型不能随便写!
LOG.info(RabbitMQCfgEnum.TEXT +"接收到消息:{}", dto);
// 设置手动确认才会需要执行此
//channel.basicAck(message.getMessageProperties().getDeliveryTag(),Boolean.TRUE);
}
[*]生产者（测试用例）
private Connection buidConnection()throws Exception{
//1.创建连接工厂
ConnectionFactory factory = new ConnectionFactory();//MQ采用工厂模式来完成连接的创建
//2.在工厂对象中设置连接信息(ip,port,virtualhost,username,password)
factory.setHost("10.156.122.215");//设置MQ安装的服务器ip地址
factory.setPort(5672);//设置端口号
factory.setVirtualHost("vhost");//设置虚拟主机名称
//MQ通过用户来管理
factory.setUsername("shadow");//设置用户名称
factory.setPassword("shadow");//设置用户密码
//3.通过工厂对象获取连接
Connection connection = factory.newConnection();
return connection;
}
@Test
public void test02()throws Exception{
Connection connection = this.buidConnection();
Channel channel = connection.createChannel();
Map<String,Object> data = new HashMap<>(4);
data.put("ordeNo", SeqGenUtil.genSeq());
data.put("timestamp",System.currentTimeMillis());
String json = JacksonUtil.toJsonString(data);
channel.basicPublish(RabbitMQCfgEnum.TEXT.exchange, RabbitMQCfgEnum.TEXT.routingKey, null,json.getBytes(StandardCharsets.UTF_8));
//关闭连接
channel.close();
connection.close();
}执行测试用例，它居然抛错了：
