WSDL 文件上的 JAX-WS 错误:“错误解析组件 's:schema'"

2022-01-19 00:00:00 wsdl java jaxb jax-ws wsimport

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.

I am using wsimport in a Java project to generate sources for three SOAP web services. The first two work fine: I use the JAX-WS Maven plugin to grab the WSDL file and generate corresponding Java source files.

这对于一项 Web 服务失败；我收到以下错误:

This fails for one web service; I get the following error:

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'.

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:

The difference between this WSDL file and the ones that work is what's at the lines noted in the error message, lines 80, 127, and 142:

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

注意:wsdl 文件的根元素定义了s"命名空间:

Note: the root element of the wsdl file defines the "s" namespace thus:

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

我已经完成了我的研究.看起来其他人也有类似的问题，解决方案从不要使用 <s:element ref="s:schema"/>"到使用导入标签"，对于显然在旧 java.net 论坛上的一些不可知的解决方案(在它被删除之前，对现代亚历山大 Java 知识库的纵火).

I have done my research. It looks like other people have had similar problems, with solutions from "just don't use <s:element ref="s:schema" />", to "use an import tag", to some unknowable solution that was apparently on the old java.net forum (before it was taken down, an arson of the modern-day Alexandrian Library of Java knowledge).

  • 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:

  • I have tried putting the following import statement just inside the element that contains the problem tags: <s:import namespace="http://www.w3.org/2001/XMLSchema" schemaLocation="http://www.w3.org/2001/XMLSchema.xsd" />. wsimport gives me a new error:

  • 我尝试将 jaxws-maven-plugin 从 1.10 升级到 2.2.同样的问题.

  • I have tried upgrading jaxws-maven-plugin from 1.10 to 2.2. Same problem.

    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.

    Any ideas? Any further information you need? I've omitted the pom.xml and Service.asmx.wsdl files for brevity, but could include them if there's more important information in them.

    谢谢！

    这是另一个遇到同样问题的人，如果这有帮助的话给任何潜在的回答者.这里还有一个类似的问题.我不太了解这篇文章，但似乎暗示我必须手动解析 SOAP XML！恐怖！

    Here's another person having the same problem, if this is helpful to any potential answerers. Here's yet another similar problem. I don't really understand this article, but it seems to imply that I have to parse the SOAP XML manually! Horror!

    推荐答案

    我通过改编解决了这个问题 Vivek Pandey 的方法 到 Maven，同时更新到 jaxws-maven-plugin 2.2.我会在这里重申它的后代:

    I solved this by adapting Vivek Pandey's method to Maven, while updating to the jaxws-maven-plugin 2.2. I'll reiterate it here for posterity:

    将这个XJB自定义文件(见下文)放在您的默认绑定文件目录中, 并设置 wsimport 来绑定它和 http://www.w3.org/2001/XMLSchema.xsd .

    Put this XJB customization file (see below) in your default binding files directory, and set wsimport to bind it and http://www.w3.org/2001/XMLSchema.xsd .

    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):

    The contents of the aforementioned XML file, xsd.xjb, that should go in your default binding files directory, is as follows (credit goes to 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 scd="~xsd:element">
