How to start Spring Kafka Application with Spring Boot

The Spring Apache Kafka (spring-kafka) provides a high-level abstraction for Kafka-based messaging solutions. And in the previous post, We had developed a Spring Kafka Application with the auto-configuration supported by SpringBoot (from version 1.5). But when we need explicitly configure Kafka factories (Kafka Producer and Kafka Consumer) for development, how to do it? So in the tutorial, JavaSampleApproach will introduce an alternative solution by manually configure Kafka factories to build a Spring Kafka Application.
