Reading an XML file

In this recipe, you'll learn to read an XML file as part of a read/process/write step.

Getting ready

We'll read this XML file:

<?xml version="1.0" encoding="UTF-8"?>
<records>
    <person>
        <firstName>Shania</firstName>
    <age>49</age>
    </person>
    <person>
        <firstName>Nelly</firstName>
    <age>36</age>
    </person>
</records>

For each person's record in the XML file, a User object will be created. Make sure that the User class exists:

public class User {
  private String firstName;
  private int age;

How to do it…

To parse the XML file, use StaxEventItemReader, which is provided by Spring Batch. To generate User objects, use XStreamMarshaller, a class from the Spring Object/XML Mapping project. Follow these steps:

1. Add the Maven dependency for Spring Object/XML Mapping in pom.xml:

   <dependency>
     <groupId>org.springframework</groupId>
     <artifactId...
