Handling XML Requests and Responses in Spring APIs with JAXB

While JSON dominates modern web services, handling XML payloads remains a critical requirement for integrating with legacy systems, enterprise banking, and classic SOAP-based architectures. This text-based course guides you through the foundational concepts of XML processing within the Spring ecosystem, showing you how to seamlessly accept and return XML data. You will gain a clear understanding of marshalling and unmarshalling processes, enabling you to integrate diverse data formats with confidence. By the end of this course, you will be able to configure Spring controllers to support content negotiation and customize your XML schema mappings using standard Java Architecture for XML Binding. What you will learn: Understand the core principles of XML marshalling and unmarshalling in enterprise web services; Configure Spring Boot controllers to accept and return both XML and JSON payloads dynamically; Apply JAXB annotations like XmlRootElement, XmlElement, and XmlType to customize the structure of your XML payloads; Map complex nested Java objects and collections to clean, structured XML documents; Implement modern API practices including custom error handling and validation for XML requests. This course starts with the absolute basics of XML-to-Java mapping and content negotiation before moving into real-world integration scenarios. It is designed for backend developers and Spring beginners who need to support XML communication in their APIs. No prior experience with JAXB or XML configuration is required.
