Question

我有多个XSD文件，我想在它们上运行XJC来创建java类对象，我将其用于进一步处理。的 ISSUE： 当我运行XJC命令时，我的XSD集中的2个XSD存在问题。 XSD是：

contactLM.xsd

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
            xmlns:w="http://w.com/xsd" 
            xmlns="http://w.com/location.contactlm" 
            xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
            targetNamespace="http://w.com/location.contactlm" 
            elementFormDefault="qualified" jaxb:version="2.1">
  <xsd:annotation>
    <xsd:appinfo>
      <jaxb:schemaBindings>
        <jaxb:package name="location.contactlm"/> 
      </jaxb:schemaBindings>
    </xsd:appinfo>
  </xsd:annotation>

  <xsd:element name="Contact" type="Contact" nillable="true"/>

  <xsd:complexType name="Contact">
    <xsd:sequence>
      <xsd:element name="RefID" type="xsd:string" nillable="true" 
                   minOccurs="0" gw:type="java.lang.String"/>
    </xsd:sequence>
  </xsd:complexType>


</xsd:schema>

contactM.xsd

<?xml version="1.0"?>
<xsd:schema
      xmlns:xsd="http://www.w3.org/2001/XMLSchema"
      xmlns:w="http://w.com/xsd"
      xmlns="http://w.com/location.contactm"
      targetNamespace="http://w.com/location.contactm"
      elementFormDefault="qualified"
      xmlns:ns0="http://w.com/location.contactam"
      xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"  
      jaxb:version="2.1">
  <xsd:annotation>
    <xsd:appinfo>
      <jaxb:schemaBindings>
        <jaxb:package name="location.contactm"/>
      </jaxb:schemaBindings>
    </xsd:appinfo>
  </xsd:annotation>
  <xsd:import namespace="http://w.com/location.contactam"
              schemaLocation="ContactAM.xsd"/>
  <xsd:element name="Contact" type="Contact" nillable="true"/>
  <xsd:complexType name="Contact">
    <xsd:sequence>
      <xsd:element name="RefID" minOccurs="0" nillable="true" 
                   type="xsd:string" gw:type="java.lang.String"/>
      <xsd:element name="WorkPhone" minOccurs="0" nillable="true" 
                   type="xsd:string" gw:type="java.lang.String"/>
    </xsd:sequence>
  </xsd:complexType>
</xsd:schema>

我知道在这些XSD文件中存在对相同“联系人”的引用，这是一个问题。所以，我不得不写我的XJB文件。我写了以下xjb文件：

<jaxb:bindings
  xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
  xmlns:gw="http://w.com/xsd" 
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  elementFormDefault="qualified" 
  xmlns="http://w.com/location.contactlm" 

  targetNamespace="http://w.com/location.contactlm" 
  jaxb:version="2.1">

     <jaxb:bindings schemaLocation="ContactM.xsd">
        <jaxb:bindings node=".//xs:element[@name='Contact']">
            <jaxb:class name="ContactM"/>
        </jaxb:bindings>
        <jaxb:schemaBindings>
            <jaxb:package name="location.contactm" />
        </jaxb:schemaBindings>
    </jaxb:bindings>

   <jaxb:bindings schemaLocation="ContactLM.xsd">
        <jaxb:bindings node=".//xs:element[@name='Contact']">
            <jaxb:class name="ContactCLM"/>
        </jaxb:bindings>
        <jaxb:schemaBindings>
            <jaxb:package name="location.contactlm" />
        </jaxb:schemaBindings>
    </jaxb:bindings>

</jaxb:bindings>

但是当我这样做时会出现以下错误：

xjc -d src -b C:\us\binding.xjb C:\us\trunk\shared\

我想我可能在XJB文件中做错了什么，但我无法解决问题。有人请帮忙。

您主要需要做的是从xsd文件中删除方案绑定。我已经复制并测试了你的文件，但它确实有效。但是，我将ContactAM的引用更改为ContactLM，假设它是拼写错误。

以下是我的文件：

ContactM.xsd

<?xml version="1.0"?>
<xsd:schema
      xmlns:xsd="http://www.w3.org/2001/XMLSchema"
      xmlns:gw="http://w.com/xsd"
      xmlns="http://w.com/location.contactm"
      targetNamespace="http://w.com/location.contactm"
      elementFormDefault="qualified"
      xmlns:ns0="http://w.com/location.contactam"
      xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"  
      jaxb:version="2.1">
  <xsd:annotation>
    <xsd:appinfo>
<!--       <jaxb:schemaBindings> -->
<!--         <jaxb:package name="location.contactm"/> -->
<!--       </jaxb:schemaBindings> -->
    </xsd:appinfo>
  </xsd:annotation>
  <xsd:import namespace="http://w.com/location.contactlm"
              schemaLocation="ContactLM.xsd"/>
  <xsd:element name="Contact" type="Contact" nillable="true"/>
  <xsd:complexType name="Contact">
    <xsd:sequence>
      <xsd:element name="RefID" minOccurs="0" nillable="true" 
                   type="xsd:string" gw:type="java.lang.String"/>
      <xsd:element name="WorkPhone" minOccurs="0" nillable="true" 
                   type="xsd:string" gw:type="java.lang.String"/>
    </xsd:sequence>
  </xsd:complexType>
</xsd:schema>

ContactLM.xsd

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
            xmlns:gw="http://w.com/xsd" 
            xmlns="http://w.com/location.contactlm" 
            xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
            targetNamespace="http://w.com/location.contactlm" 
            elementFormDefault="qualified" jaxb:version="2.1">
  <xsd:annotation>
    <xsd:appinfo>
<!--       <jaxb:schemaBindings> -->
<!--         <jaxb:package name="location.contactm"/> -->
<!--       </jaxb:schemaBindings> -->
    </xsd:appinfo>
  </xsd:annotation>

  <xsd:element name="Contact" type="Contact" nillable="true"/>

  <xsd:complexType name="Contact">
    <xsd:sequence>
      <xsd:element name="RefID" type="xsd:string" nillable="true" 
                   minOccurs="0" gw:type="java.lang.String"/>
    </xsd:sequence>
  </xsd:complexType>


</xsd:schema>

最后是绑定文件：

bind.xjb

<jaxb:bindings
  xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
  xmlns:gw="http://w.com/xsd" 
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  elementFormDefault="qualified" 
  xmlns="http://w.com/location.contactlm" 

  targetNamespace="http://w.com/location.contactlm" 
  jaxb:version="2.1">

     <jaxb:bindings schemaLocation="ContactM.xsd">
        <jaxb:bindings node=".//xs:element[@name='Contact']">
            <jaxb:class name="ContactM"/>
        </jaxb:bindings>
        <jaxb:schemaBindings>
            <jaxb:package name="location.contactm" />
        </jaxb:schemaBindings>
    </jaxb:bindings>

   <jaxb:bindings schemaLocation="ContactLM.xsd">
        <jaxb:bindings node=".//xs:element[@name='Contact']">
            <jaxb:class name="ContactCLM"/>
        </jaxb:bindings>
        <jaxb:schemaBindings>
            <jaxb:package name="location.contactlm" />
        </jaxb:schemaBindings>
    </jaxb:bindings>

</jaxb:bindings>

为了完整起见，这是我的命令及其输出

D:\stackoverflow\sample>xjc ContactM.xsd -b bind.xjb
parsing a schema...
compiling a schema...
location\contactm\Contact.java
location\contactm\ContactM.java
location\contactm\ObjectFactory.java
location\contactm\package-info.java
location\contactlm\Contact.java
location\contactlm\ContactCLM.java
location\contactlm\ObjectFactory.java
location\contactlm\package-info.java

希望这有帮助。
