使用binding.xml重命名JAXB根类

Question

我使用Eclipse中的Dali插件使用xsd文件生成Java类，它实际上只是在模式文件上调用xjc。我使用这里的建议通过将XML绑定文件应用于类生成来解决命名冲突。这很有效，但我试图通过重命名根元素更进一步，结果丢失了XmlRootElement注释。我尝试使用annox将根元素注释添加回来，但是我得到了这个错误：不受支持的绑定命名空间“http://annox.dev.java.net”。也许您指的是“http://java.sun.com/xml/ns/jaxb/xjc”？

<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" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
    version="2.1">
    <!-- Force all classes to be generated at the top level, this will potentially cause name conflicts -->
    <jaxb:globalBindings localScoping="toplevel"/>
    <jaxb:bindings schemaLocation="mySchema-1.0.0.xsd">
        <!-- Rename the root element -->
        <jaxb:bindings node="//xs:element[@name='MyRootClassNameIsReallyLong']/xs:complexType">
            <jaxb:class name="ShorterName"/>
        </jaxb:bindings>
        <!-- Rename the Bar class to resolve a naming conflict -->
        <jaxb:bindings node="//xs:element[@name='Foo']/xs:complexType/xs:sequence/xs:element[@name='Bar']/xs:complexType">
            <jaxb:class name="FooBar"/>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>

编辑（9/11/2013）-以下是与Annox的绑定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" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
    xmlns:annox="http://annox.dev.java.net"
    version="2.1">
    <!-- Force all classes to be generated at the top level, this will potentially cause name conflicts -->
    <jaxb:globalBindings localScoping="toplevel"/>
    <jaxb:bindings schemaLocation="mySchema-1.0.0.xsd">
        <!-- Rename the root element -->
        <jaxb:bindings node="//xs:element[@name='MyRootClassNameIsReallyLong']/xs:complexType">
            <jaxb:class name="ShorterName"/>
            <annox:annotate>
                <annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="MyRootClassNameIsReallyLong" />
            </annox:annotate>
        </jaxb:bindings>
        <!-- Rename the Bar class to resolve a naming conflict -->
        <jaxb:bindings node="//xs:element[@name='Foo']/xs:complexType/xs:sequence/xs:element[@name='Bar']/xs:complexType">
            <jaxb:class name="FooBar"/>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>

Annox是一个XJC添加，因此除了声明命名空间prefx(xmlns:Annox=“http://Annox.dev.java.net)之外，还需要将其声明为extensionbindingprefix。

您的开始标记应该如下所示：

<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"                 
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb 
                                   http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
               jaxb:extensionBindingPrefix="annox"
               version="2.1">
