使用 JaxB 创建 Java 类

Question

我尝试通过此 XSD http://pda.rosreestr.ru/upload/www/files/02_V04_STD_Region_Cadastr_KV.rar 使用 JaXB 创建 Java 类，但遇到了这些错误。

parsing a schema...
[WARNING] Simple type "dAllDocuments" was not mapped to Enum due to EnumMemberSizeCap limit. Facets count: 298, current limit: 256. You can use customization attribute "typesafeEnumMaxMembers" to extend the limit.
line 3 of file:/D:/liferay-develop/workspace/JABX_test/src/02_V04_STD_Region_Cadastr_KV/dAllDocuments.xsd

compiling a schema...
[ERROR] Two declarations cause a collision in the ObjectFactory class.
line 1645 of file:/D:/liferay-develop/workspace/JABX_test/src/02_V04_STD_Region_Cadastr_KV/STD_Region_Cadastr_KV.xsd

[ERROR] (Related to above error) This is the other declaration.   
line 1587 of file:/D:/liferay-develop/workspace/JABX_test/src/02_V04_STD_Region_Cadastr_KV/STD_Region_Cadastr_KV.xsd

Failed to produce code.

当我使用其他模式时，一切都很好。我不擅长使用 XML，您能告诉我这些错误是什么意思以及如何解决吗？

更新

我尝试在类生成中使用 binding.xml，但出现此错误。

C:\Documents and Settings\kliver\Мои документы\Загрузки\jaxb-ri-2.2.6\bin>xjc -d
out -b binding.xml D:/liferay-develop/workspace/JABX_test/src/02_V04_STD_Region

更新2

我试试这个绑定：

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

    <!-- Raise theEnumMemberSizeCap limit -->
    <jxb:bindings >
       <jxb:globalBindings typesafeEnumMaxMembers="2000"/>
   </jxb:bindings>

   <jxb:bindings schemaLocation="D:\liferay-develop\workspace\JABX_test\src\02_V04_STD_Region_Cadastr_KV\STD_Region_Cadastr_KV.xsd">
       <jxb:bindings node="//xs:complexType[@name='tRight_Owner']">
           <jxb:class name="tRight_Owner2"/>
       </jxb:bindings>
   </jxb:bindings>

</jxb:bindings>

还有这个控制台命令：

C:\Documents and Settings\kliver\Мои документы\Загрузки\jaxb-ri-2.2.6\bin>xjc -d
out -b binding.xml D:\liferay-develop\workspace\JABX_test\src\02_V04_STD_Region
_Cadastr_KV\STD_Region_Cadastr_KV.xsd

Answer 1

您可以使用外部绑定文件为其中一种复杂类型指定不同的类名。

binding.xml

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

   <!-- Raise theEnumMemberSizeCap limit -->
   <jxb:bindings >
       <jxb:globalBindings typesafeEnumMaxMembers="2000"/>
   </jxb:bindings>

    <jxb:bindings schemaLocation="your-schema.xsd">
            <jxb:bindings node="//xs:complexType[@name='tRight_Owner']">
                <jxb:class name="TRight_Owner2"/>
            </jxb:bindings>
    </jxb:bindings>

</jxb:bindings>

xjc 命令行是：

xjc -d out -b binding.xml your-schema.xsd

Answer 2

对于那些后来遇到这个问题的人来说，这种方法对我有用。

环境：Netbeans 7.4

构建方法：Maven - jaxb2-maven-plugin

1. 在src\main 中创建一个名为xjb 的文件夹。
2. 在该文件夹中创建一个名为 binding.xjb（或任何其他 .xjb 名称）的文件。

在里面：

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

   <!-- Raise theEnumMemberSizeCap limit -->
   <jxb:bindings >
       <jxb:globalBindings typesafeEnumMaxMembers="2000"/>
   </jxb:bindings>

</jxb:bindings>

请注意，这不是 Blaise 帖子的替代解决方案。

Answer 3

我使用的是 0.13.0 版的 maven-jaxb2-plugin，我发现绑定文件的正确路径是：

src/main/resources/binding.xjb

内容与OldCurmudgeon提出的相同，即：

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

    <!-- Raise theEnumMemberSizeCap limit -->
    <jxb:bindings>
        <jxb:globalBindings typesafeEnumMaxMembers="2000" />
    </jxb:bindings>

</jxb:bindings>

您的 XSD 有问题，有多个同名声明 tRight_Owner
第 1587 行：

 <xs:complexType>
                        <xs:complexContent>
                            <xs:extension base="tRight_Owner"/>
                        </xs:complexContent>
                    </xs:complexType>

第 1645 行：

<xs:complexType name="tRight_Owner">
