5.2. 运行 Kafka 集成

运行制作者集成

1. 创建示例制作者集成。这会用每 10 秒填充一条消息。

   Sample SaslSSLKafkaProducer.java

   // kamel run --secret kafka-props SaslSSLKafkaProducer.java --dev
   // camel-k: language=java dependency=mvn:org.apache.camel.quarkus:camel-quarkus-kafka dependency=mvn:io.strimzi:kafka-oauth-client:0.7.1.redhat-00003
   
   import org.apache.camel.builder.RouteBuilder;
   import org.apache.camel.component.kafka.KafkaConstants;
   
   public class SaslSSLKafkaProducer extends RouteBuilder {
     @Override
     public void configure() throws Exception {
     log.info("About to start route: Timer -> Kafka ");
     from("timer:foo")
       .routeId("FromTimer2Kafka")
       .setBody()
         .simple("Message #${exchangeProperty.CamelTimerCounter}")
       .to("kafka:{{producer.topic}}")
       .log("Message correctly sent to the topic!");
     }
   }

2. 然后运行流程集成。

   kamel run --secret kafka-props SaslSSLKafkaProducer.java --dev

   Copy to Clipboard Toggle word wrap

   该制作者将创建一个新消息并推送至主题并记录一些信息。

   [2] 2021-05-06 08:48:11,854 INFO  [FromTimer2Kafka] (Camel (camel-1) thread #1 - KafkaProducer[test]) Message correctly sent to the topic!
   [2] 2021-05-06 08:48:11,854 INFO  [FromTimer2Kafka] (Camel (camel-1) thread #3 - KafkaProducer[test]) Message correctly sent to the topic!
   [2] 2021-05-06 08:48:11,973 INFO  [FromTimer2Kafka] (Camel (camel-1) thread #5 - KafkaProducer[test]) Message correctly sent to the topic!
   [2] 2021-05-06 08:48:12,970 INFO  [FromTimer2Kafka] (Camel (camel-1) thread #7 - KafkaProducer[test]) Message correctly sent to the topic!
   [2] 2021-05-06 08:48:13,970 INFO  [FromTimer2Kafka] (Camel (camel-1) thread #9 - KafkaProducer[test]) Message correctly sent to the topic!

运行消费者集成

1. 创建消费者集成。

   Sample SaslSSLKafkaProducer.java

   // kamel run --secret kafka-props SaslSSLKafkaConsumer.java --dev
   // camel-k: language=java dependency=mvn:org.apache.camel.quarkus:camel-quarkus-kafka dependency=mvn:io.strimzi:kafka-oauth-client:0.7.1.redhat-00003
   
   import org.apache.camel.builder.RouteBuilder;
   
   public class SaslSSLKafkaConsumer extends RouteBuilder {
     @Override
     public void configure() throws Exception {
   	log.info("About to start route: Kafka -> Log ");
   	from("kafka:{{consumer.topic}}")
       .routeId("FromKafka2Log")
       .log("${body}");
     }
   }

2. 打开另一个 shell，并使用命令运行使用者集成：

   kamel run --secret kafka-props SaslSSLKafkaConsumer.java --dev

   Copy to Clipboard Toggle word wrap

   消费者将开始记录主题中找到的事件：

   [1] 2021-05-06 08:51:08,991 INFO  [FromKafka2Log] (Camel (camel-1) thread #0 - KafkaConsumer[test]) Message #8
   [1] 2021-05-06 08:51:10,065 INFO  [FromKafka2Log] (Camel (camel-1) thread #0 - KafkaConsumer[test]) Message #9
   [1] 2021-05-06 08:51:10,991 INFO  [FromKafka2Log] (Camel (camel-1) thread #0 - KafkaConsumer[test]) Message #10
   [1] 2021-05-06 08:51:11,991 INFO  [FromKafka2Log] (Camel (camel-1) thread #0 - KafkaConsumer[test]) Message #11
