我有一个具有相同名称的多个级别的大型架构。 （我没有写它！）

注意名称为＆＃34; Layout＆＃34;的3个元素。我尝试使用xjb文件来更改每个文件的类名，如下所示：
<bindings xmlns="http://java.sun.com/xml/ns/jaxb" xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.1">
<bindings schemaLocation="MetrixJDF.xsd" version="1.0">
<globalBindings localScoping="toplevel" />
<schemaBindings xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc">
<package name="com.metrixsoftware.vdp.jdf">
</package>
</schemaBindings>
<bindings node="//xs:element[@name='JDF']">
<bindings node="//xs:attribute[@ref='ssi:WorkStyle']">
<property name="ssiWorkStyle" />
</bindings>
</bindings>
<bindings
node="//xs:element[@name='ResourcePool']/xs:complexType/xs:sequence/xs:element[@name='Layout']/xs:complexType/xs:sequence/xs:element[@name='Layout']/xs:complexType/xs:sequence/xs:element[@name='Layout']">
<class name="Layout3" />
</bindings>
<bindings node="//xs:element[@name='ResourcePool']/xs:complexType/xs:sequence/xs:element[@name='Layout']/xs:complexType/xs:sequence/xs:element[@name='Layout']">
<class name="Layout2" />
</bindings>
<bindings node="//xs:element[@name='ResourcePool']/xs:complexType/xs:sequence/xs:element[@name='Layout']">
<class name="Layout1" />
</bindings>
</bindings>
</bindings>
这似乎不起作用。我没有收到有关xjb文件的任何错误，但在运行xjc时仍然出现这些错误：

答案 0 :(得分：1)
我确实遇到了错误，但它不是在xjc编译期间（使用xjc 2.2.8-b130911.1802），但由于ResourcePool中的重复静态类名布局，生成的Java代码是非法的。我无法使用外部绑定解决此问题。
以下对XML Schema的修改 - 不会更改XML布局允许生成正确的Java代码：
<xs:element name="ResourcePool">
<xs:complexType>
<xs:sequence>
<xs:element name="Layout" type="jdf:LayoutLev1"/>
<!-- keep the remainder of the element as it is -->
新的复杂类型：
<xs:complexType name="LayoutLev1">
<xs:sequence>
<xs:element name="Layout" type="jdf:LayoutLev2" maxOccurs="unbounded" minOccurs="0"/>
</xs:sequence>
<xs:attribute type="xs:string" name="Class" />
<xs:attribute type="xs:string" name="DescriptiveName" />
<xs:attribute type="xs:string" name="ID" />
<xs:attribute type="xs:string" name="PartIDKeys" />
<xs:attribute type="xs:string" name="Status" />
</xs:complexType>
<xs:complexType name="LayoutLev2">
<xs:sequence>
<xs:element name="Layout">
<!-- keep the rest till the end of complexType -->
