Generating Java JAXB classes from an XSD schema is a common task. In this tutorial I show you how to use the maven-jaxb2-plugin to generate the JAXB java classes. (From group org.jvnet.jaxb2.maven2).
By the way - have you tried MOXy? I actually find it more maintainable than handing JAXB objects; but thats another video topic!.
I additionally show you how to use Spring Framework OXM Jaxb2Marshaller to marshal JAXB java objects into XML and unmarshal XML into JAXB java objects.
00:00 - 01:23 Tutorial Introduction from a beach in Andalusia; Spain. During my morning walk.
01:23 - 01:46 Create Spring Starter Project
01:46 - 02:40 Created XML XSD Schema
02:40 - 03:50 Added maven-jaxb2-plugin to the applications POM
03:50 - 04:40 Generated the JAXB Java Objects representing the schema
04:40 - 04:52 Added Spring Framework OXM dependency to the POM
04:52 - 08:55 Created Spring Jaxb2Marshaller with context path, schema resource validation and pretty print property.
08:55 - 10:33 Created JAXB Java Objects to perform marshalling on
10:33 - 12:30 Marshalled JAXB Java Object into XML with Jaxb2Marshaller StreamResult and StringWriter. Could also use StringResult.
12:30 - 13:00 Fixed the exception thrown by adding the missing context path and schema properties.
13:00 - 14:45 Unmarshalled XML into JAXB java objects using Jaxb2Marshaller StreamSource and StringReader.

Doesn't work anymore. Here some fixes. Add a dependency org.glassfish.jaxb jaxb-runtime Change code on JaxbConfig.java here: from in method signature: @Value("${schema.location}") final Resource schemaResource to in method signature: @Value("${schema.location}") final String schemaResource inside the method: Resource schema = new ClassPathResource(schemaResource); marshaller.setSchema(schema); See Stackoverflow: stackoverflow.com/questions/43429514/resource-servletcontext-resource-does-not-exist and Github jaxb- issues: github.com/eclipse-ee4j/jaxb-ri/issues/1235#issuecomment-474306717
