java - WSDL 文件 : "Error resolving component ' s:schema'"上的 JAX-WS 错误

Question

错误

我在一个 Java 项目中使用 wsimport 来为三个 SOAP Web 服务生成源代码。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:

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

---

我的尝试

我已经完成了我的研究。看起来其他人也遇到过类似的问题，从“只是不要使用 <s:element ref="s:schema" />”到“使用导入标签”，再到一些显然在旧 java.net 论坛上的不可知解决方案(之前它是取缔，对现代亚历山大 Java 知识图书馆的纵火)。

• 我尝试将以下导入语句放在包含问题标签的元素中:<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:

  [jaxws:wsimport]

    line 200 of file:/home/me/NetBeansProjects/Admin/AdminWeb/src/wsdl/erp-app-devel.srv.mycompany.ca/EgTestReportEngine/Service.asmx.wsdl
  

  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。

• Here's a possible solution -- 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

有什么想法吗？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，但如果其中有更重要的信息，可以包含它们。

谢谢!

Here's another person having the same problem ，如果这对任何潜在的回答者有帮助。 Here's yet another similar problem.我不太明白this article ，但这似乎暗示我必须手动解析 SOAP XML!恐怖!

Answer 1

我通过改编 Vivek Pandey's method 解决了这个问题到 Maven，同时更新到 jaxws-maven-plugin 2.2。我会在这里重申它的后代:

总结

把 this XJB customization file (见下文)在您的默认绑定(bind)文件目录中，并将 wsimport 设置为绑定(bind)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(bind)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>
