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:

看吧json字符串是无法序列化为Map😂

试试用dto来接收这个json字符串看:

  • 消费者
    @RabbitListener(queues = "text.queue")
    @RabbitHandler(isDefault = true)
    public void exec(@Payload MQMessageDTO 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);
    }
    
  • 消费者接收对象
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

import java.io.Serializable;

@JsonIgnoreProperties(ignoreUnknown = true)
public class MQMessageDTO implements Serializable {

    /**
     * 序列化标识
     */
    private static final long serialVersionUID = 1L;

    private String ordeNo;
    private Long timestamp;

    public String getOrdeNo() {
        return ordeNo;
    }

    public void setOrdeNo(String ordeNo) {
        this.ordeNo = ordeNo;
    }

    public Long getTimestamp() {
        return timestamp;
    }

    public void setTimestamp(Long timestamp) {
        this.timestamp = timestamp;
    }

    @Override
    public String toString() {
        return "MQMessageDTO{" +
                "ordeNo='" + ordeNo + '\'' +
                ", timestamp=" + timestamp +
                '}';
    }

}

再执行下测试用例看看:

还是一样的抛错😂

没办法,我们得用先前能走通的调试下Consumer的Message这个参数看:

看到了有个貌似是参数类型的东东出现在了inferredArgumentType这个参数位置,对头~,可以试着将类型放进去不就好了嘛,试试看~

  • 消费者
    @RabbitListener(queues = "default.queue")
    @RabbitHandler(isDefault = true)
    public void exec(@Payload MQMessageDTO 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.DEFAULT +"接收到消息:{}", dto);
    }
  • 测试用例
    @Test
    public void test03()throws Exception{
        Connection connection = this.buidConnection();
        Channel channel = connection.createChannel();
        MQMessageDTO data = new MQMessageDTO();
        data.setOrdeNo(SeqGenUtil.genSeq());
        data.setTimestamp(System.currentTimeMillis());
       MessageProperties messageProperties = new MessageProperties();
        messageProperties.setInferredArgumentType(MQMessageDTO.class);
        messageProperties.setContentType("application/x-java-serialized-object");
        Message message = new SimpleMessageConverter().toMessage(data, messageProperties);
        channel.basicPublish(RabbitMQCfgEnum.TEXT.exchange, RabbitMQCfgEnum.TEXT.routingKey, null,message.getBody());
        //关闭连接
        channel.close();
        connection.close();
    }

试着运行了下测试用例,发现还是抛错😂

可能思路还是存在问题,这样吧,先用RabbitTemplate推一个消息看
主要代码如下:

    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void sendDefaultDirect() {
        MQMessageDTO data = new MQMessageDTO();
        data.setOrdeNo(SeqGenUtil.genSeq());
        data.setTimestamp(System.currentTimeMillis());
        // 注意,发送的消息必须是实现了Serializable类型的消息,接收的时候也应该是这个类型,不可乱写
        rabbitTemplate.convertAndSend(RabbitMQCfgEnum.DEFAULT.exchange, RabbitMQCfgEnum.DEFAULT.routingKey,data);
        LOG.info("已发送::{}",data );
    }

能收到消息:

2023-07-17 15:36:17.354 -> [org.springframework.amqp.rabbit.RabbitListenerEndpointContainer#0-1] -> INFO  c.m.a.common.service.impl.MQConsumerDefaultHandler:49 - 
    DEFAULT接收到消息:MQMessageDTO{ordeNo='2307171536109000', timestamp=1689579370802}

花了幾分鐘,試著在RabbitTemplate下找到了这段代码:

	protected void sendToRabbit(Channel channel, String exchange, String routingKey, boolean mandatory,
			Message message) throws IOException {
		BasicProperties convertedMessageProperties = this.messagePropertiesConverter
				.fromMessageProperties(message.getMessageProperties(), this.encoding);
		channel.basicPublish(exchange, routingKey, mandatory, convertedMessageProperties, message.getBody());
	}

好家伙,原来需要传一个 BasicProperties 对象,copy之~

  • 测试用例
    @Test
    public void test03()throws Exception{
        Connection connection = this.buidConnection();
        //mq提供Channel来将处理消息
        //创建Channel
        Channel channel = connection.createChannel();
        MQMessageDTO data = new MQMessageDTO();
        data.setOrdeNo(SeqGenUtil.genSeq());
        data.setTimestamp(System.currentTimeMillis());
        Message message = new SimpleMessageConverter().toMessage(data, new MessageProperties());
        AMQP.BasicProperties prop = new DefaultMessagePropertiesConverter().fromMessageProperties(message.getMessageProperties(), "UTF-8");

        channel.basicPublish(RabbitMQCfgEnum.TEXT.exchange, RabbitMQCfgEnum.TEXT.routingKey, prop,message.getBody());
        //关闭连接
        channel.close();
        connection.close();
    }
  • 执行结果
2023-07-17 15:41:20.880 -> [org.springframework.amqp.rabbit.RabbitListenerEndpointContainer#1-1] -> INFO  c.m.api.common.service.impl.MQConsumerTextHandler:43 - 
    TEXT接收到消息:MQMessageDTO{ordeNo='2307171541179000', timestamp=1689579677767}

基本结论:
在springboot框架下mq消费者接收生产者的消息内容,如果想统一封装则只能用字符串的形式!这点儿很重要,因为发送方配置中指定了发送消息的内容类型~
但是,如果生产者与消费者不是在一个应用,能不能用同一个类型接收呢,这是个好问题,试试看~

二.模拟发送方与接收方参数测试

为了真实模拟,我将上面使用过的这个消息体MQMessageDTO copy一份到其他包里面,生产者与消费者使用不同包下的MQMessageDTO

最终的代码是这样子:

  • 消费者
    @RabbitListener(queues = "text.queue")
    @RabbitHandler(isDefault = true)
    public void exec(@Payload com.mee.api.common.dto.MQMessageDTO 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)
    @Test
    public void test03()throws Exception{
        Connection connection = this.buidConnection();
        //mq提供Channel来将处理消息
        //创建Channel
        Channel channel = connection.createChannel();
        com.mee.api.common.dto.tmp.MQMessageDTO data = new com.mee.api.common.dto.tmp.MQMessageDTO();
        data.setOrdeNo(SeqGenUtil.genSeq());
        data.setTimestamp(System.currentTimeMillis());
        Message message = new SimpleMessageConverter().toMessage(data, new MessageProperties());
        AMQP.BasicProperties prop = new DefaultMessagePropertiesConverter().fromMessageProperties(message.getMessageProperties(), "UTF-8");

        channel.basicPublish(RabbitMQCfgEnum.TEXT.exchange, RabbitMQCfgEnum.TEXT.routingKey, prop,message.getBody());
        //关闭连接
        channel.close();
        connection.close();
    }

这上面有一句话很重要:

Cannot convert from [com.mee.api.common.dto.tmp.MQMessageDTO] to [com.mee.api.common.dto.MQMessageDTO]

所以在不同的应用下使用mq ,需要用相同包下的相同类传递参数。

总结:springboot下mq序列化的方式有三

  • 1.使用默认的SimpleMessageConverter实现序列化

  • 2.配置使用Jackson2JsonMessageConverter(jackson),配置如下

    @Bean
    public RabbitListenerContainerFactory<?> rabbitListenerContainerFactory(ConnectionFactory connectionFactory,ObjectMapper objectMapper){
        SimpleRabbitListenerContainerFactory simpleRabbitListenerContainerFactory = new SimpleRabbitListenerContainerFactory();
        simpleRabbitListenerContainerFactory.setConnectionFactory(connectionFactory);
        simpleRabbitListenerContainerFactory.setMessageConverter(new Jackson2JsonMessageConverter(objectMapper));
        return simpleRabbitListenerContainerFactory;
    }

    @Bean
    public RabbitTemplate jackRabbitTemplate(ConnectionFactory connectionFactory){
        RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
        rabbitTemplate.setMessageConverter(new Jackson2JsonMessageConverter());
        return rabbitTemplate;
    }

    @Bean
    public MessageConverter jsonConvert(ObjectMapper objectMapper){
        return new Jackson2JsonMessageConverter(objectMapper);
    }
  • 3.统一String传递消息内容,接收时用如下方式还原为String
String msgStr = new String(bt,StandardCharsets.UTF_8);

如需要转换为特定类型请自行使用fastjson,jackson,gson等等方式将字符串序列化为指定对象即可~
