在使用 XJC 生成 Java 源时使用 JAXWS enableWrapperStyle

Question

我正在尝试从 XSD 生成 Java 源并且必须禁用 JAXWS 的包装器样式。我已经编写了自定义绑定，但 JAXWS 似乎不适用于 XJC。我使用的绑定非常简单。

<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:jaxws="http://java.sun.com/xml/ns/jaxws" xmlns="http://java.sun.com/xml/ns/jaxws"
version="2.1" jaxb:extensionBindingPrefixes="xjc">

<jaxb:bindings>
    <jaxb:globalBindings typesafeEnumMaxMembers="2000" generateElementProperty="false" >
         <jaxws:enableWrapperStyle>false</jaxws:enableWrapperStyle>
    </jaxb:globalBindings>
</jaxb:bindings>

如果我尝试运行 ant 脚本，我会收到以下错误消息。

 [xjc] [ERROR] Unsupported binding namespace "http://java.sun.com/xml/ns/jaxws". Perhaps you meant "http://java.sun.com/xml/ns/jaxb/xjc"?
  [xjc]   line 2 of file:/D:/xxxxxxxxxx/xxxxx/xxxx.xsd

  [xjc]   line 8 of file:/D:/xxxxxxxxxx/xxxxx/xxxx/xsd/xsd-binding.xml

我已经尝试过仅使用 jaxws，但 XJC 将 JAXB 扩展为主要绑定。使用此绑定：

<bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://java.sun.com/xml/ns/jaxws"
    jaxb:version="2.1" extensionBindingPrefixes="xjc annox">
    <enableWrapperStyle>false</enableWrapperStyle>
    <jaxb:bindings>
        <jaxb:globalBindings typesafeEnumMaxMembers="2000" generateElementProperty="false" />
    </jaxb:bindings>
</bindings>

我遇到错误：

[xjc] [ERROR] not an external binding file. The root element must be {http://java.sun.com/xml/ns/jaxb}bindings but it is {http://java.sun.com/xml/ns/jaxws}bindings
      [xjc]   line ? of file:/D:/xxxxxx/xsd-binding.xml
      [xjc] [ERROR] Unexpected <bindings> appears at line 4 column 61
      [xjc]   line 4 of file:/D:/xxxxxx/xsd-binding.xml

是否可以在 jaxb 中使用 jaxws:enableWrapperStyle？如果是，我忽略了什么？提前致谢！

我找到了解决办法。 JAXWS 元素必须在 JAXB 元素内部并且必须按如下方式声明：

<?xml version="1.0"?>
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.1" jaxb:extensionBindingPrefixes="xjc annox">
    <jaxws:bindings xmlns:jaxws="http://java.sun.com/xml/ns/jaxws">
        <jaxws:enableWrapperStyle>false</jaxws:enableWrapperStyle>
    </jaxws:bindings>
    <jaxb:bindings>
        <jaxb:globalBindings typesafeEnumMaxMembers="2000" generateElementProperty="false"/>
    </jaxb:bindings>
</jaxb:bindings>
