我正在尝试使用来自 jaxb2_commons maven 组的 jaxb2-basics 工件添加接口。

我的 pom.xml 包含以下依赖项

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.2.7</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.2.6</version>
</dependency>
<dependency>
  <groupId>org.jvnet.jaxb2_commons</groupId>
  <artifactId>jaxb2-basics-runtime</artifactId>
  <version>0.6.4</version>
</dependency>

插件配置看起来像

从上面可以看出，xjc 有两次调用，它们都有效。专注于第一个，我的绑定文件

<jaxb:bindings
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
  xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
  xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
  jaxb:extensionBindingPrefixes="xjc"
  version="1.0">
  <jaxb:bindings schemaLocation="../schema/MESSAGES-IN.xsd" node="/xs:schema">
    <jaxb:globalBindings typesafeEnumMaxMembers="3000">
      <jaxb:serializable uid="1"/>
    </jaxb:globalBindings>
    <jaxb:schemaBindings>
      <jaxb:package name="com.whatever.messages.request"/>
    </jaxb:schemaBindings>
    <jaxb:bindings node="//xs:simpleType[@name='YesOrNo']">
      <jaxb:class ref="com.whatever.messages.YesOrNo"/>
    </jaxb:bindings>
    <jaxb:bindings noade="//xs:complexType[@name='someLogin']">
      <jaxb:class name="LoginRequest">
        <jaxb:javadoc><![CDATA[A Login request message.]]>
        </jaxb:javadoc>
      </jaxb:class>
    </jaxb:bindings>
  </jaxb:bindings>
</jaxb:bindings>

奇迹般有效; 但是，当我尝试向“LoginRequest”添加接口时......

   <jaxb:bindings node="//xs:complexType[@name='someLogin']">
     <jaxb:class name="LoginRequest">
       <jaxb:javadoc><![CDATA[A Login request message.]]>
       </jaxb:javadoc>
     </jaxb:class>
     <inheritance:implements>com.whatever.messages.Request</inheritance:implements>
   </jaxb:bindings>

我收到错误消息

 Error while parsing schema(s).Location [ file:/C:/Users/justme/Documents/NetBeansProjects/someproject/src/main/binding/messages-in-binding.xjb{19,42}].
 com.sun.istack.SAXParseException2; systemId: file:/C:/Users/justme/Documents/NetBeansProjects/someproject/src/main/binding/messsages-in-binding.xjb; lineNumber: 19; columnNumber: 42; compiler was unable to honor this class customization. It is attached to a wrong place, or its inconsistent with other bindings.

报告该位置是

 Error while generating code.Location [ file:/C:/Users/justme/Documents/NetBeansProjects/someproject/src/main/schema/MESSAGES-IN.xsd{106693,54}].

恰好对应于

 <xs:complexType name="someLogin" mixed="true">
   ...
 </xs:complexType>

现在，我尝试了第二个指令将接口绑定到 XSD 元素

 <xs:element name="someLogin" type="someLogin" substitutionGroup="externalMethod"/>

但我只是收到与元素的行号相同的错误消息作为位置。

显然，有人想将接口附加到类，并且所有示例看起来都非常接近我的绑定文件，但一定有问题。

我的环境是

Apache Maven 3.0.4 (r1232337; 2012-01-17 02:44:56-0600)
Maven home: C:\Program Files\NetBeans 7.2.1\java\maven
Java version: 1.7.0_07, vendor: Oracle Corporation
Java home: C:\Program Files (x86)\Java\jdk1.7.0_07\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "x86", family: "windows"

有人可以解释为什么 xjc 认为扩展在错误的 XSD 类型上运行吗？

在施工

<jaxb:bindings 
  node="//Xs:complexType[@name='someLogin">
  ...
</jaxb:bindings>

该node属性应该是一个 XPath 表达式。（或者它在Oracle上是这么说的）。尝试添加右方括号使其成为一个，看看是否有帮助。
