JAXB2 基础插件 - 我的外部绑定自定义文件中的 schemaLocation 问题

Question

我正在使用 JAXB 从我的 XSD 文件生成类。我想让生成的类实现一个通用接口。因此，我正在尝试使用 external binding file 方法来执行 JAXB2 Basics 插件。这是我的自定义绑定文件：

customBindingFile.xjb

<?xml version="1.0"?>
<jxb:bindings version="1.0" 
  xmlns:jxb="http://java.sun.com/xml/ns/jaxb" 
  xmlns:xs="http://www.w3.org/2001/XMLSchema" 
  xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
  xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
  jxb:extensionBindingPrefixes="xjc">

    <jxb:bindings schemaLocation="abc-api.xsd">
      <jxb:bindings node="//xs:complexType[@name='MyClass']">
        <inheritance:implements>com.kuldeep.CommonInterface</inheritance:implements> 
      </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

以下是我用于生成源代码的 pom 文件中的 maven 插件：请注意 我添加的注释 是我对现有插件条目所做的更改。

pom.xml

</plugin>

我遇到的问题是我的模式文件 abc-api.xsd 驻留在其他一些项目中，所以当我尝试执行 maven 安装以生成我的类，我收到错误提示 abc-api.xsd 不是此编译的一部分。

[ERROR] Failed to execute goal org.apache.cxf:cxf-codegen-plugin:3.0.3:wsdl2java (generate-sources) on project : Execution generate-sources of goal org.apache.cxf:cxf-codegen-plugin:3.0.3:wsdl2java failed: file:/I:/project/src/main/resources/customBindingFile.xjb [9,56]: "file:/I:/project/src/main/resources/abc-api.xsd" is not a part of this compilation. Is this a mistake for "file:/I:/project/src/main/resources/jaxb_binding.xml"? -> [Help 1]

如果我从 customBindingFile.xjb 中删除 schemaLocation 属性，它不起作用并给出错误：

XPath evaluation of "//xs:complexType[@name='MyClass']" results in empty target node

所以我的问题是如何避免在 customBindingFile.xjb 中提供特定的架构文件 name/location 并将其应用于 xsd ] 它用于生成类.

Answer 1

在我们的架构师的帮助下，我解决了这个问题。我添加了一个 jaxws 绑定文件并在其中使用了无前缀的 xpath 查询来匹配我的请求元素。这样我就不需要在任何地方提供模式位置，它将根据 XPath 查询应用于特定的 WSDL。

jaxws_binding_inheritance.xml

<jaxws:bindings version="2.0" xmlns:jaxws="http://java.sun.com/xml/ns/jaxws" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
  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="inheritance xjc"
  xmlns:jxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.1">

  <jaxws:enableWrapperStyle>false</jaxws:enableWrapperStyle>

  <jaxws:bindings
    node="*[local-name()='definitions']/*[local-name()='types']/*[local-name()='schema' and 
          (@targetNamespace='urn:net:mycompany:api:abc')]">

    <jaxb:bindings
      node="//*[local-name()='element' and 
            not(@name = 'ExcludeThisRequest' or @name = 'AlsoExcludeThisRequest') and 
            (substring(@name, string-length(@name) - string-length('Request') +1) = 'Request')]/*[local-name()='complexType']">
      <inheritance:implements>com.kuldeep.CommonRequest</inheritance:implements>
    </jaxb:bindings>

  </jaxws:bindings>
</jaxws:bindings>

并在 wsdloption 下为我想应用它的 wsdl 添加了 jaxws 绑定文件 (jaxws_binding_inheritance.xml)。

pom.xml

<wsdlOption>
  <wsdl>${project.build.directory}/generated/framework/cxf/abc-api-inline.wsdl</wsdl>
  <bindingFiles>
    <bindingFile>src/main/resources/jaxws_binding_inheritance.xml</bindingFile>
  </bindingFiles>
</wsdlOption>
