Spring CORS example using @CrossOrigin – Spring Boot

Cross-Origin-Resource-Sharing (CORS) is a W3C specification which defines how a browser should be allowed using script to access different origin than the origin it has been served. With CORS, we can specify what kind of cross domain requests are authorized in a flexible way, instead of using some less secured and less powerful hacks like IFRAME or JSONP. In this tutorial, we’re gonna look at way to create a Spring Boot REST service with Spring CORS integration using @CrossOrigin annotation.

How to use Spring Kafka JsonSerializer (JsonDeserializer) to produce/consume Java Object messages

In the previous post, we had setup a Spring Kafka Application succesfully by explicitly configuration Kafka Factories with SpringBoot. But the messages had been used have String type. While in the development, POJO (Plain Old Java Object) are often used to construct messages. So with the tutorial, JavaSampleApproach will show how to use Spring Kafka JsonSerializer (JsonDeserializer) to produce/consume Java Object messages.

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.
