错误

我在 Java 项目中使用 wsimport 为三个 SOAP Web 服务生成源。前两个工作正常:我使用 JAX-WS Maven 插件来抓取 WSDL 文件并生成相应的 Java 源文件。

这对于一项 Web 服务失败;我收到以下错误:

[jaxws:wsimport]
Processing: /home/me/NetBeansProjects/Admin/AdminWeb/src/wsdl/erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx.wsdl
jaxws:wsimport args: [-s, /home/me/NetBeansProjects/Admin/AdminWeb/target/generated-sources/jaxws-wsimport, -d, /home/me/NetBeansProjects/Admin/AdminWeb/target/classes, -verbose, -catalog, /home/me/NetBeansProjects/Admin/AdminWeb/src/jax-ws-catalog.xml, -wsdllocation, http://erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx?WSDL, -target, 2.0, -extension, -Xnocompile, /home/me/NetBeansProjects/Admin/AdminWeb/src/wsdl/erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx.wsdl]
parsing WSDL...


src-resolve.4.2: Error resolving component 's:schema'. It was detected that 's:schema' is in namespace 'http://www.w3.org/2001/XMLSchema', but components from this namespace are not referenceable from schema document 'file:/home/me/NetBeansProjects/Admin/AdminWeb/src/wsdl/erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx.wsdl#types?schema1'. If this is the incorrect namespace, perhaps the prefix of 's:schema' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:/home/me/NetBeansProjects/Admin/AdminWeb/src/wsdl/erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx.wsdl#types?schema1'.

罪魁祸首

此 WSDL 文件与有效文件之间的区别在于错误消息中指出的行,第 80、127 和 142 行:

<s:element ref="s:schema" />

注意:wsdl 文件的根元素定义了“s”命名空间,因此:

xmlns:s="http://www.w3.org/2001/XMLSchema" 


我试过的

我已经完成了我的研究。看起来其他人也有类似的问题,从“只是不使用<s:element ref="s:schema" />”到“使用导入标签”的解决方案,到一些显然在旧的 java.net 论坛上的不可知的解决方案(在它被删除之前,现代亚历山大 Java 知识图书馆的纵火案)。

  • 我尝试将以下导入语句放在包含问题标签的元素内:<s:import namespace="http://www.w3.org/2001/XMLSchema" schemaLocation="http://www.w3.org/2001/XMLSchema.xsd" />. wsimport 给了我一个新错误:

    此错误中引用的第 108 行和第 109 行是:(第 184-5、199-200 行类似)

    <s:any minOccurs="0" maxOccurs="unbounded" namespace="http://www.w3.org/2001/XMLSchema" processContents="lax" />
    <s:any minOccurs="1" namespace="urn:schemas-microsoft-com:xml-diffgram-v1" processContents="lax" />
    
  • 我尝试将 jaxws-maven-plugin 从 1.10 升级到 2.2。同样的问题。

  • 这是一个可能的解决方案——我试图弄清楚如何使用 JAX-WS Maven 插件来实现它。有什么提示吗?


结论

有任何想法吗?您需要任何进一步的信息吗?为简洁起见,我省略了 pom.xml 和 Service.asmx.wsdl 文件,但如果其中包含更重要的信息,可以包含它们。

谢谢!


附加物

这是另一个有同样问题的人,如果这对任何潜在的回答者有帮助的话。 这是另一个类似的问题。 我不是很了解这篇文章,但似乎暗示我必须手动解析 SOAP XML!恐怖!

我通过将Vivek Pandey 的方法适应Maven 解决了这个问题,同时更新到 jaxws-maven-plugin 2.2。为了后代,我将在这里重申:

概括

将此 XJB 定制文件(见下文)放在您的默认绑定文件目录中,并设置 wsimport 以绑定它和http://www.w3.org/2001/XMLSchema.xsd

XJB定制

上述 XML 文件 xsd.xjb 的内容应该放在您的默认绑定文件目录中,如下所示(归功于 Kohsuke):

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
          xmlns:xsd="http://www.w3.org/2001/XMLSchema"
          xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
          version="2.0">

  <globalBindings>
    <xjc:simple />
  </globalBindings>

  <bindings scd="~xsd:complexType">
    <class name="ComplexTypeType"/>
  </bindings>

  <bindings scd="~xsd:simpleType">
    <class name="SimpleTypeType"/>
  </bindings>

  <bindings scd="~xsd:group">
    <class name="GroupType"/>
  </bindings>

  <bindings scd="~xsd:attributeGroup">
    <class name="AttributeGroupType"/>
  </bindings>

  <bindings scd="~xsd:element">
    <class name="ElementType"/>
  </bindings>

  <bindings scd="~xsd:attribute">
    <class name="attributeType"/>
  </bindings>
</bindings>

聚甲醛

这是我的 POM 文件的相关部分,并注明了更改:

要使 Nick 的解决方案起作用,您可能必须将这两个 jvm 参数添加到您的 pom.xml 所以当遇到这些错误时:

org.xml.sax.SAXParseException;系统标识:http : //www.w3.org/2001/XMLSchema.xsd;行号:67;列号:11;外部 DTD:无法读取外部 DTD“XMLSchema.dtd”,因为 accessExternalDTD 属性设置的限制不允许“http”访问。

[警告] schema_reference:无法读取架构文档“xml.xsd”,因为 accessExternalSchema 属性设置的限制不允许“http”访问。http://www.w3.org/2001/XMLSchema.xsd的第 91 行

只需将它们添加到您的 pom.xml

-Djavax.xml.accessExternalDTD=all
-Djavax.xml.accessExternalSchema=all

<vmArgs>
    <vmArg>-Djavax.xml.accessExternalDTD=all</vmArg>
    <vmArg>-Djavax.xml.accessExternalSchema=all</vmArg>
</vmArgs>

使用以下命令修复了相同的问题:

wsimport -b http://www.w3.org/2001/XMLSchema.xsd -b xsd.xjb service.wsdl

其中xsd.xjb指的是:

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
          xmlns:xsd="http://www.w3.org/2001/XMLSchema"
          xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
          version="2.0">

  <globalBindings>
    <xjc:simple />
  </globalBindings>

  <bindings scd="~xsd:complexType">
    <class name="ComplexTypeType"/>
  </bindings>

  <bindings scd="~xsd:simpleType">
    <class name="SimpleTypeType"/>
  </bindings>

  <bindings scd="~xsd:group">
    <class name="GroupType"/>
  </bindings>

  <bindings scd="~xsd:attributeGroup">
    <class name="AttributeGroupType"/>
  </bindings>

  <bindings scd="~xsd:element">
    <class name="ElementType"/>
  </bindings>

  <bindings scd="~xsd:attribute">
    <class name="attributeType"/>
  </bindings>
</bindings>

如果您实际上并不关心模型数据的这一特定位,您可以使用 JAXB 绑定文件告诉 JAXB 将有问题的位映射到类型为 DOM 的属性,Element而不是实际尝试将它们数据绑定到正常JAXB 类。非官方的JAXB 指南有一节介绍这种技术。

这似乎最终对我有用。我正在使用 apache maven cfx 插件
