springboot下使用rabbitMQ之傳參及序列化(二)
消息參數傳遞在開發中也是個坑，不論使用內置的SimpleMessageConverter還是Jackson2JsonMessageConverter均無法讓Consumer接收動態參數
一.序列化的問題
首先貼出具體代碼以及測試用例:
- 消費者
@RabbitListener(queues = "text.queue")
@RabbitHandler(isDefault = true)
public void exec(@Payload Map dto, Message message, Channel channel){
// 注意，發送的消息類型必須是實現了Serializable接口的類型，消費者接口類型不能隨便寫!
LOG.info(RabbitMQCfgEnum.TEXT +"接收到消息:{}", dto);
// 設置手動確認纔會需要執行此
//channel.basicAck(message.getMessageProperties().getDeliveryTag(),Boolean.TRUE);
}
- 生產者（測試用例）
private Connection buidConnection()throws Exception{
//1.創建連接工廠
ConnectionFactory factory = new ConnectionFactory();//MQ採用工廠模式來完成連接的創建
//2.在工廠對象中設置連接信息(ip,port,virtualhost,username,password)
factory.setHost("10.156.122.215");//設置MQ安裝的服務器ip地址
factory.setPort(5672);//設置端口號
factory.setVirtualHost("vhost");//設置虛擬主機名稱
//MQ通過用戶來管理
factory.setUsername("shadow");//設置用戶名稱
factory.setPassword("shadow");//設置用戶密碼
//3.通過工廠對象獲取連接
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));
//關閉連接
channel.close();
connection.close();
}
執行測試用例，它居然拋錯了：

看吧json字符串是無法序列化爲Map😂
試試用dto來接收這個json字符串看:
- 消費者
@RabbitListener(queues = "text.queue")
@RabbitHandler(isDefault = true)
public void exec(@Payload MQMessageDTO dto, Message message, Channel channel){
// 注意，發送的消息類型必須是實現了Serializable接口的類型，消費者接口類型不能隨便寫!
LOG.info(RabbitMQCfgEnum.TEXT +"接收到消息:{}", dto);
// 設置手動確認纔會需要執行此
//channel.basicAck(message.getMessageProperties().getDeliveryTag(),Boolean.TRUE);
}
- 消費者接收對象
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import java.io.Serializable;
@JsonIgnoreProperties(ignoreUnknown = true)
public class MQMessageDTO implements Serializable {
/**
* 序列化標識
*/
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 +
'}';
}
}
再執行下測試用例看看:

還是一樣的拋錯😂
沒辦法，我們得用先前能走通的調試下Consumer的Message這個參數看:
看到了有個貌似是參數類型的東東出現在了inferredArgumentType這個參數位置,對頭～，可以試着將類型放進去不就好了嘛，試試看~
- 消費者
@RabbitListener(queues = "default.queue")
@RabbitHandler(isDefault = true)
public void exec(@Payload MQMessageDTO dto, Message message, Channel channel){
// 注意，發送的消息類型必須是實現了Serializable接口的類型，消費者接口類型不能隨便寫!
LOG.info(RabbitMQCfgEnum.DEFAULT +"接收到消息:{}", dto);
}
- 測試用例
@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());
//關閉連接
channel.close();
connection.close();
}
試着運行了下測試用例，發現還是拋錯😂

可能思路還是存在問題，這樣吧，先用RabbitTemplate推一個消息看
主要代碼如下:
@Autowired
private RabbitTemplate rabbitTemplate;
public void sendDefaultDirect() {
MQMessageDTO data = new MQMessageDTO();
data.setOrdeNo(SeqGenUtil.genSeq());
data.setTimestamp(System.currentTimeMillis());
// 注意，發送的消息必須是實現了Serializable類型的消息，接收的時候也應該是這個類型,不可亂寫
rabbitTemplate.convertAndSend(RabbitMQCfgEnum.DEFAULT.exchange, RabbitMQCfgEnum.DEFAULT.routingKey,data);
LOG.info("已發送::{}",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下找到了這段代碼：
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());
}
好傢伙，原來需要傳一個 BasicProperties 對象，copy之~
- 測試用例
@Test
public void test03()throws Exception{
Connection connection = this.buidConnection();
//mq提供Channel來將處理消息
//創建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());
//關閉連接
channel.close();
connection.close();
}
- 執行結果
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}
基本結論:
在springboot框架下mq消費者接收生產者的消息內容，如果想統一封裝則只能用字符串的形式！這點兒很重要，因爲發送方配置中指定了發送消息的內容類型~
但是，如果生產者與消費者不是在一個應用，能不能用同一個類型接收呢，這是個好問題，試試看~
二.模擬發送方與接收方參數測試
爲了真實模擬，我將上面使用過的這個消息體MQMessageDTO copy一份到其他包裏面,生產者與消費者使用不同包下的MQMessageDTO：
最終的代碼是這樣子:
- 消費者
@RabbitListener(queues = "text.queue")
@RabbitHandler(isDefault = true)
public void exec(@Payload com.mee.api.common.dto.MQMessageDTO dto, Message message, Channel channel){
// 注意，發送的消息類型必須是實現了Serializable接口的類型，消費者接口類型不能隨便寫!
LOG.info(RabbitMQCfgEnum.TEXT +"接收到消息:{}", dto);
// 設置手動確認纔會需要執行此
//channel.basicAck(message.getMessageProperties().getDeliveryTag(),Boolean.TRUE);
}
- 生產者(測試用例)
@Test
public void test03()throws Exception{
Connection connection = this.buidConnection();
//mq提供Channel來將處理消息
//創建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());
//關閉連接
channel.close();
connection.close();
}

這上面有一句話很重要：
Cannot convert from [com.mee.api.common.dto.tmp.MQMessageDTO] to [com.mee.api.common.dto.MQMessageDTO]
所以在不同的應用下使用mq ，需要用相同包下的相同類傳遞參數。
總結：springboot下mq序列化的方式有三
-
1.使用默認的
SimpleMessageConverter實現序列化 -
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.統一
String傳遞消息內容，接收時用如下方式還原爲String
String msgStr = new String(bt,StandardCharsets.UTF_8);
如需要轉換爲特定類型請自行使用fastjson,jackson,gson等等方式將字符串序列化爲指定對象即可～
