JAXB的混合内容无法使用WSDL

Question

我正在使用NetBeans,我有两个项目:

• 用于生成Web服务并将其部署到GlassFish的EJB模块
• 一个简单的控制台客户端,用于测试和使用此Web服务

对于web服务,我使用的是带有混合内容元素的XSD.使用以下代码为JAXB导入添加绑定文件:

<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings
 xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
 xmlns:xjc= "http://java.sun.com/xml/ns/jaxb/xjc" jaxb:extensionBindingPrefixes="xjc"
 jaxb:version="2.0">
  <jaxb:globalBindings generateMixedExtensions="true"/>
</jaxb:bindings>

它生成了这段代码:

@XmlMixed
@OverrideAnnotationOf
protected List<Serializable> contentOverrideForED;

我可以使用这个生成的代码,虽然它并不理想.

我的问题在于客户端,我已经为我生成和部署的webservice添加了一个Web服务引用,只在localhost上运行.

使用相同的绑定文件WSDL Customization: External Binding File不会产生content代码,也不会直接使用它作为选项Wsimport,也不会将其用作Jaxb option.我有一种感觉,这种设置在某种程度上被忽视了,但是怎么样？

为什么最初的JAXB生成包括它以及wsimport为什么不使用它？我有点困惑.

您可能需要考虑使用 Eclipse 来生成您需要的内容。尽管您正在使用的 xsd 和 wsdl 未包含在问题中，但我提出了一个似乎可行的简单示例。我没有使用绑定文件，Eclipse 中的向导选择了需要 mix 的事实，因为 XSD 中的 mix="true" （可能想尝试没有绑定的情况）：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/NewXMLSchema" xmlns:tns="http://www.example.org/NewXMLSchema" elementFormDefault="qualified">

<xs:element name="letter">
  <xs:complexType mixed="true">
    <xs:sequence>
      <xs:element name="name" type="xs:string"/>
      <xs:element name="orderid" type="xs:positiveInteger"/>
      <xs:element name="shipdate" type="xs:date"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

</xs:schema>
