I. Technologies for convert Java Object into/from XML tutorial

– Java 1.8
– Maven 3.3.9
– Spring Tool Suite – Version 3.8.1.RELEASE
– Castor

II. Overview
1. Project Structure
2. Step to do
– Create SpringBoot project
– Create simple Model
– Create XML Converter
– Configure CastorMarshaller & XmlConverter
– Create Mapping file
– Develop main class for checking Marshalling & Unmarshalling
– Run & Check Results

III. Practices

1. Create SpringBoot project
– Open Spring Tool Suite, on main menu, choose File-New-Spring Starter Project, add project info. Press Next, then Finish, a Spring Boot project will be created successfully.
Open pom.xml file, add needed dependencies: Spring Oxm, Castor & xerces

2. Create simple Model
– Create Customer model

3. Create XML Converter
Create XML Converter for handling Marshaller and Unmarshaller

4. Configure CastorMarshaller & XmlConverter
Because CastorMarshaller implements both Marshaller & Unmarshaller, so CastorMarshaller bean can use for XMLConverter as Marshaller & Unmarshaller:
– public class CastorMarshaller extends AbstractMarshaller
– public abstract class AbstractMarshaller implements Marshaller, Unmarshaller

5. Create Mapping file
Mapping file is a way to control what field is element or attribute.
For locating the mapping file, use setMappingLocation method: castorMarshaller.setMappingLocation(appContext.getResource(“classpath:mapping.xml”));

6. Develop main class for checking Marshalling & Unmarshalling
In main class of SpringBoot

7. Run & Check Results
Run the project with Spring Boot App mode.
