Question

我有以下xsd架构，并希望生成的文件从超类扩展：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="myRequest">
        <xs:complexType>
            ...
        </xs:complexType>
    </xs:element>
</xs:schema>

MY-binding.xml：

<jaxb:bindings    
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    jaxb:extensionBindingPrefixes="xjc"   
    jaxb:version="2.1">

        <jaxb:bindings schemaLocation="xsd/myRequest.xsd">
            <jaxb:bindings node="//xs:element[@name='myRequest']">  
                <xjc:superClass name="com.commons.MyMessage"/>
            </jaxb:bindings>
        </jaxb:bindings>    

</jaxb:bindings>

的pom.xml：

        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-xjc-plugin</artifactId>
        <configuration>

                    </dependency>
                </dependencies>
            </configuration>
            <goals>
                <goal>xsdtojava</goal>
            </goals>
        </execution>
    </executions>
</plugin>

超类：

public class MyMessage {
    private String sessionID;
    //getter, setter
}

mvn generate-sources的结果：该类未被继承。但我没有得到任何错误。为什么呢？

您可以使用JAXB2继承插件（它允许实现接口或类的扩展）

Generating a JAXB class that implements an interface

如何在jaxb生成期间为特定元素继承超类？
