Unmarshalling XML Data into Java Objects using Spring Boot

In modern software development, integrating different data formats is a common task. XML, a widely used markup language, is often encountered. Unmarshalling XML data into Java objects is a crucial process, as it allows you to work with structured data more efficiently. In this article, we’ll explore how to achieve XML unmarshalling using the Spring Boot framework.

Step 1: Set Up Dependencies

Begin by creating a Spring Boot project. In your project’s pom.xml (Maven) or build.gradle (Gradle), add the necessary dependencies. You'll need spring-boot-starter-web to set up the Spring Boot environment and jaxb-api for Java Architecture for XML Binding (JAXB)

<!-- For Maven -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
</dependency>

Step 2: Create XML Model

Define your Java classes that mirror the XML structure. Use JAXB annotations to establish the mapping between XML elements and Java fields. For instance, let’s create a Person class representing a person's name and age.

import javax.xml.bind.annotation.XmlElement;
import…
