Answer 1

You need ErrorHandlingDeserializer: https://docs.spring.io/spring-kafka/docs/2.2.0.RELEASE/reference/html/_reference.html#error-handling-deserializer

If you can't move to that 2.2 version, consider to implement your own and return null for those records which can't be deserialized properly.

The source code is here: https://github.com/spring-projects/spring-kafka/blob/master/spring-kafka/src/main/java/org/springframework/kafka/support/serializer/ErrorHandlingDeserializer2.java
