Spring-Kafka : Issue while deserialising kafka message - class not in a “trusted package”?

Question

I get the below exception because I produce from one project and the consumer consumes from another project. How can I fix this. Obviously the packages are not the same. So

Answer 1

You can whitelist your package by changing assessmentAttemptDetailsEntityConsumerFactory() like this:

    @Bean
    public ConsumerFactory assessmentAttemptDetailsEntityConsumerFactory() {
            JsonDeserializer 
            deserializer = new JsonDeserializer<>();
            deserializer.addTrustedPackages("com.lte.assessment.assessments");//your package
        return new DefaultKafkaConsumerFactory(config,deserializer);
    }
