apache cxf logo
Apache CXF is an open source services framework that helps build and develop services using frontend programming APIs, like JAX-WS. In this tutorial we will take a look at how we can integrate CXF with Spring Boot in order to build and run a Hello World SOAP service. Throughout the example, we will be creating a contract first client and endpoint using a WSDL, CXF, Spring Boot and Maven.

The Spring Kafka project comes with a spring-kafka-test JAR that contains a number of useful utilities to assist you with your application testing. These include: an embedded Kafka server, some static methods to setup consumers/producers and some utility methods to fetch results.

Let's demonstrate how you can use these utilities with some runnable code. We will reuse the Spring Kafka Hello World project from a previous post in which we created a consumer and producer using Spring Kafka, Spring Boot and Maven.

The Spring for Apache Kafka (spring-kafka) project applies core Spring concepts to the development of Kafka-based messaging solutions. It provides a "template" as a high-level abstraction for sending messages. It also provides support for Message-driven POJOs with @KafkaListener annotations and a 'listener container'.

In the following tutorial we will configure, build and run a Hello World example in which we will send/receive messages to/from Apache Kafka using Spring Kafka, Spring Boot and Maven. Before running below code, make sure that Apache Kafka is installed and started.
