java - 将 WSDL 文件写入现有 Web 服务

标签 java xsd wsdl axis wsdl2java

我需要将 WSDL 文件写入同事提供给我的现有 Web 服务(它是用 Perl 和 SOAP::Lite 实现的)。因此，我有一个给定的 SOAP 响应格式，需要正式定义服务才能为服务的 Java 客户端生成代码。为了针对服务测试 WSDL 文件，我一直在使用 Eclipse 的 Web 服务资源管理器和 soapUI 来为客户端生成代码，我打算使用随 Eclipse (1.3.x) 一起分发的 Axis 版本。

我现在拥有的定义文件确实可以通过 soapUI 访问服务并返回所需的 SOAP 响应，soapUI 也可以断言它符合 Schema，但是如果我从中生成代码并尝试运行代码，事情开始分崩离析。显然，Axis 无法正确识别定义的类型，而只是创建具有“anyType”类型的成员。因此无法正确序列化响应，导致 SAX 解析器出现异常。

当我尝试验证我的 WSDL 文件时，我被告知不允许将一个元素定义为只包含另一个元素的子元素，我认为这是我遇到麻烦的根源。我试图将“prefix_map”元素嵌套到匿名 complexType 中作为序列的单个项目，但现在 soupUI 中的架构合规性断言失败了。那么如何为给定的响应正确定义响应消息的类型呢？

这是我从服务获得的 SOAP 响应:

 <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/1999/XMLSchema">
    <SOAP-ENV:Body>
    <namesp1:get_dest_prefixResponse xmlns:namesp1="PortaTAPI">

          <country xsi:type="xsd:string">SWITZERLAND</country>
          <iso_3166_1_a2 xsi:type="xsd:string">CH</iso_3166_1_a2>

          <i_dest xsi:type="xsd:int">10007</i_dest>
          <description xsi:type="xsd:string">Customer AG - Wholesale</description>

          <dest_type xsi:null="1"/>

       </prefix_map>
    </namesp1:get_dest_prefixResponse>

这是客户端(由 Axis 生成)抛出的异常:

感谢您的帮助!

最佳答案

好的。在您在下面发表评论后，我完善了我的答案。我相信 Axis 正在寻找相关元素的具体类型。由于它没有定义，它假设它是任何类型，然后它很难处理。我会做以下事情:

<xsd:element name="get_dest_prefix">
 <xsd:complexType>
  <xsd:all>
   <xsd:element name="prefix" type="xsd:long" minOccurs="1" />
   <xsd:element name="i_env" type="xsd:int" minOccurs="1" />
  </xsd:all>
 </xsd:complexType>
</xsd:element>
<xsd:element name="get_dest_prefixResponse" type="tns:t_get_dest_prefixResponse"/>
<xsd:complexType name="t_get_dest_prefixResponse">
  <xsd:sequence>
    <xsd:element name="prefix_map" type="tns:t_prefix_map" minOccurs="1"/>
  </xsd:sequence>
</xsd:complexType>

这有帮助吗？这可能会使它更加明确，并允许 Axis 找到它想要的东西。
