如何从XSD编辑生成的Java类

Question

I am using maven-jaxb2-plugin to create java classes from xsd. In xsd I have defined two status: Status1 and Status2. This two classes has a lot of similar variables. Because I cant edit xsd is there a option to create class Status in my project and then add change generated class to extend this class?

Example

now:

Class Status1 {...}

Class Status2 {...}

• this is generated by maven-jaxb2-plugin

What I want:

Class Status1 extends Status {...}

Class Status2 extends Status {...}

• this is generated by maven-jaxb2-plugin

Class Status {...} - my own class

I hope this can be done by bindings but I dont know how

UPDATE:

second option how to achieve this question is to add to class Status1 new variable. Is this possible ?

What I want:

Class Status1 {... NewVariable newVariable ...}

Class Status2 {...}

• this is generated by maven-jaxb2-plugin

Answer 1

ok I found it: I use extend:

<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    jaxb:version="2.1" xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
    jaxb:extensionBindingPrefixes="inheritance">
    <jaxb:bindings schemaLocation="mySchema.xsd">
        <jaxb:bindings node="xsd:complexType[@name='StatusType']">
            <inheritance:extends>my.package.Status1</inheritance:extends>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>

and in JAXB2 plugin I need to add:

                    <extension>true</extension>
                    <args>
                        <arg>-Xinheritance</arg>
                    </args>
                    <plugins>
                        <plugin>
                            <groupId>org.jvnet.jaxb2_commons</groupId>
                            <artifactId>jaxb2-basics</artifactId>
                            <version>0.6.4</version>
                        </plugin>
                    </plugins>

For the first part of the question see Specifying Super Class of a JAXB-Generated Class .

For the second part see Generate additional custom method with jaxb-xjc . It's about adding custom methods. But custom fields handling should be similar.
