Java 元素在WSDL中具有相同的名称和不同的类型

java jaxb

Java 元素在WSDL中具有相同的名称和不同的类型,java,jaxb,jax-ws,wsdl2java,Java,Jaxb,Jax Ws,Wsdl2java,我得到了一个WSDL和模式文件。我使用这些文件在Java中创建存根。但是我在生成错误时遇到了一个错误（如下）。我知道问题是什么，只是不知道怎么解决。我知道问题是，有时PayLoadLength是字符串或整数 <xs:element name="PayloadLength" type="xs:string" minOccurs="0"/> 经过相当广泛的分析，问题似乎是在所谓的“包装风格”。引述：注意：JAX-WS2.1规范中定义的“包装样式”和“非包装样式”的含义可能与直觉相反。

我得到了一个WSDL和模式文件。我使用这些文件在Java中创建存根。但是我在生成错误时遇到了一个错误（如下）。我知道问题是什么，只是不知道怎么解决。我知道问题是，有时PayLoadLength是字符串或整数

<xs:element name="PayloadLength" type="xs:string" minOccurs="0"/>

经过相当广泛的分析，问题似乎是在所谓的“包装风格”。引述：

注意：JAX-WS2.1规范中定义的“包装样式”和“非包装样式”的含义可能与直觉相反。包装器样式表示请求消息中的每个数据元素都有自己的Java参数，而非包装器样式表示包含所有数据元素的单个Java对象充当web服务方法调用的唯一参数

所以基本上问题是，如果请求和响应类型中有一些子元素具有相同的名称，那么它们基本上会映射到一个参数。如果它们有不同的类型，这会导致冲突，CXF会拒绝它们

解决此问题的一种方法是禁用包装器样式。您可以使用

binding.xml

文件执行此操作，如：

<jaxws:bindings node="wsdl:definitions" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
    <jaxws:enableWrapperStyle>false</jaxws:enableWrapperStyle>
</jaxws:bindings>

可能还有另一种方法，至少是错误消息，至少错误消息表明应该可以“使用JAXWS/JAXB绑定定制来重命名参数”。不幸的是，我无法找到适合此应用的绑定语法。

我认为我们缺少了一些东西。这真的是你的模式吗？如果

Request

和

Response

是完全独立的类型（根据您的代码），那么具有相同名称和不同类型的元素应该不会有任何问题。他们可能都扩展了超级类型吗？对不起，我更改了响应和请求的名称。我没有看到它们都扩展的超级类型。问题是，您发布的模式片段很可能不会产生您报告的问题。所以请发一封信。完整且可验证。在那之前，我将投票决定关闭。@lexicore我发布了架构文件。我只是在每次调用中都保留了PayLoadLength元素。您还需要wsdl文件吗？我可以使用

xjc

毫无问题地编译您的模式。我认为让MCVE准备好构建项目并通过GitHub共享是有意义的。那我去看看。
