JAXB, Equals and hashCode methods

I have no need to have a equals and hashCode methods on generated java class yet but I need it now.

It is really simple. You have to use a specific jaxb plugin (in case of Maven) and plugins for this plugin ;-)

- Maven2 plugin: org.jvnet.jaxb2.maven2:maven-jaxb2-plugin
- configuration: -XtoString, -Xequals, -XhashCode
- plugin for Maven2 plugin: org.jvnet.jaxb2_commons:jaxb2-basics

While java classes are being generated this plugin hooks at the process and add equals and hashCode methods. My pom definition:

<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.7.4</version>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<clearOutputDir>true</clearOutputDir>
<extension>true</extension>
<schemaDirectory>target/schemas</schemaDirectory>

</configuration>
</execution>
</executions>
<configuration>
<args>
<arg>-XtoString</arg>
<arg>-Xequals</arg>
<arg>-XhashCode</arg>
</args>
<plugins>
<plugin>
<groupId>org.jvnet.jaxb2_commons</groupId>
<artifactId>jaxb2-basics</artifactId>
<version>${version.jaxb2-basics}</version>
</plugin>
</plugins>
</configuration>
</plugin>

That's it!
