从Quarkus消费Debezium主题中的消息,可以使用Quarkus提供的Quarkus Kafka扩展来实现。
Quarkus是一种基于GraalVM和OpenJDK的Java框架,旨在优化Java应用程序的性能和内存占用。Debezium是一个开源的分布式事件捕获平台,可用于监听和捕获数据库更改事件。
要从Quarkus消费Debezium主题中的消息,您需要遵循以下步骤:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-kafka</artifactId>
</dependency>
import io.quarkus.kafka.client.serialization.JsonbDeserializer;
import io.quarkus.runtime.Startup;
import org.apache.kafka.clients.consumer.ConsumerRecord;
import org.eclipse.microprofile.reactive.messaging.Incoming;
@Startup
public class MyKafkaConsumer {
@Incoming("my-topic")
public void consume(ConsumerRecord<String, MyMessage> record) {
MyMessage message = record.value();
// 处理消息
}
}
kafka.bootstrap.servers=my-kafka-server:9092
mp.messaging.incoming.my-topic.connector=debezium
mp.messaging.incoming.my-topic.debezium.connector.class=io.debezium.connector.mysql.MySqlConnector
mp.messaging.incoming.my-topic.debezium.offset.storage=org.apache.kafka.connect.storage.FileOffsetBackingStore
mp.messaging.incoming.my-topic.debezium.offset.storage.file.filename=data/offsets.dat
mp.messaging.incoming.my-topic.debezium.offset.flush.interval.ms=60000
mp.messaging.incoming.my-topic.debezium.database.hostname=my-db-host
mp.messaging.incoming.my-topic.debezium.database.port=3306
mp.messaging.incoming.my-topic.debezium.database.user=my-db-username
mp.messaging.incoming.my-topic.debezium.database.password=my-db-password
mp.messaging.incoming.my-topic.debezium.database.dbname=my-db-name
mp.messaging.incoming.my-topic.debezium.database.server.id=1
mp.messaging.incoming.my-topic.debezium.database.server.name=my-server-name
mp.messaging.incoming.my-topic.debezium.table.include.list=my-table-name
mp.messaging.incoming.my-topic.debezium.transforms.unwrap.type=io.debezium.transforms.ExtractNewRecordState
mp.messaging.incoming.my-topic.debezium.transforms.unwrap.drop.tombstones=true
mp.messaging.incoming.my-topic.debezium.transforms.unwrap.delete.handling.mode=drop
mp.messaging.incoming.my-topic.value.deserializer=io.quarkus.kafka.client.serialization.JsonbDeserializer
mp.messaging.incoming.my-topic.key.deserializer=org.apache.kafka.common.serialization.StringDeserializer
在上述配置中,您需要根据实际情况修改Debezium的连接信息和主题配置。
consume
方法中,您可以编写逻辑来处理接收到的消息。推荐的腾讯云相关产品:腾讯云消息队列 CMQ(Cloud Message Queue),链接地址:https://cloud.tencent.com/product/cmq
