Here is what I add to my yaml file:
camel.component.kafka.configuration.value-deserializer:
com.openbet.platform.pricepublisher.serde.SportsEventDeserializer
and here is my route:
from("kafka:prices?brokers={{kafka.servers}}")
.convertBodyTo(DBModel.class)
......
With this setup when I start the app I can see in the logs the Kafka
configuration in the consumer:
value.deserializer = class
org.apache.kafka.common.serialization.StringDeserializer
and I get exceptions while deserializing. However if I remove the config from
the yaml file and update my route to be:
kafka:prices?brokers={{kafka.servers}}&valueDeserializer=com.openbet.platform.pricepublisher.serde.SportsEventDeserializer
then I see the following in the Kafka consumer config:
value.deserializer = class
com.openbet.platform.pricepublisher.serde.SportsEventDeserializer
and the app works as expected. Just for reference the rest of my yaml file is:
kafka:
sportsTopic: sports
pricesTopic: prices
servers: localhost:25445
streams:
"[application.id]": price-publisher
"[bootstrap.servers]": ${kafka.servers}
"[default.key.serde]":
com.openbet.platform.pricepublisher.serde.ActivityKeySerDe
"[default.value.serde]":
com.openbet.platform.pricepublisher.serde.ActivityValueSerDe
Thank you,
