JAXB2 Basics 简化插件抛出 "Cannot find the declaration of element 'simplify:property'" 异常

Question

我正在尝试使用 jaxb2 基础知识 "simplify" 插件，但我总是收到以下异常...

[INFO] --- jaxws-maven-plugin:2.2:wsimport (default) @ dsmlv2-jaxws ---

parsing WSDL...


[ERROR] cvc-elt.1: Cannot find the declaration of element 'simplify:property'.

我有一个 jaxb bindings.xml 文件，看起来像这样...

<bindings xmlns="http://java.sun.com/xml/ns/jaxb" 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:simplify="http://jaxb2-commons.dev.java.net/basic/simplify" jaxb:extensionBindingPrefixes="xjc simplify" jaxb:version="2.1">

   <jaxb:bindings>
      <jaxb:globalBindings typesafeEnumMaxMembers="2000">
         <xjc:simple />
         <xjc:serializable uid="456" />
      </jaxb:globalBindings>
   </jaxb:bindings>

   <jaxb:bindings scd="x-schema::tns" xmlns:tns="urn:oasis:names:tc:DSML:2:0:core">
      <jaxb:schemaBindings>
         <jaxb:package name="oasis.dsml.v2_0.model" />
      </jaxb:schemaBindings>
      <jaxb:bindings scd="~tns:BatchRequest">
         <simplify:property name="fooOrBar">
            <simplify:as-element-property />
         </simplify:property>
      </jaxb:bindings>
   </jaxb:bindings>

</bindings>

在我的 pom 中，我正在尝试使用 cxf-codegen-plugin 和 jaxws-maven-plugin 编译我的 WSDL。我使用哪一个并不重要，我在 jaxb 绑定文件中使用时遇到相同的异常。插件配置如下...

Answer 1

通常你需要 configuration 下的 plugins 节点来让 xjc 能够加载插件。

<plugins>
  <plugin>
    <groupId>org.jvnet.jaxb2_commons</groupId>
    <artifactId>jaxb2-basics</artifactId>
    <version>${jaxb2-basics.version}</version>
  </plugin>
</plugins>

Answer 2

您正在击中 JAXB-1047 - SCD bindings do not support custom/vendor customization elements。

没有解决方法，只能改用 XPath 绑定。
