java - WSDL 或 wsimport 和 wsdl (mono) 严重损坏

Question

编辑 我从下面给出的例子开始，但我现在有:

• 尝试了 W3C 规范中的示例。修复另一个错误后(绑定(bind)在一个地方被称为 StockQuoteSoapBinding，在另一个地方被称为 StockQuoteBinding)，它给出了同样的问题。
• 尝试了单声道生成器 wsdl 以查看是否是 wsimport 造成的。它给出了一个等效的错误。

所以在我看来，尽管对 SOAP 大肆宣传，但它实际上并没有用——至少不像宣传的那样。我不敢相信没有人通过这些生成器运行最容易找到的 wsdl 示例。

原始问题

wsimport 在以下 wsdl 上失败:

<?xml version="1.0" encoding="UTF-8"?>

  </wsdl:service>

</wsdl:definitions>

与:

parsing WSDL...


[ERROR] Schema descriptor {http://example/schema/OrdersService}GetOrders in message part "parameters" is not defined and could not be bound to Java. Perhaps the schema descriptor {http://example/schema/OrdersService}GetOrders is not defined in the schema imported/included in the WSDL. You can either add such imports/includes or run wsimport and provide the schema location using -b switch.

虽然问题很老，但这里有一个有效的 WSDL:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="OrdersService"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
  xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
  xmlns:os="http://example/schema/OrdersService"
  xmlns:tns="http://example/ns/OrdersService"
  targetNamespace="http://example/ns/OrdersService">

  <wsdl:types>
    <xsd:schema targetNamespace="http://example/schema/OrdersService">

      <xsd:element name="GetOrders">
        <xsd:complexType>
          <xsd:sequence>
            <xsd:element name="criteria" type="xsd:string" />
          </xsd:sequence>
        </xsd:complexType>
      </xsd:element>

      <xsd:element name="GetOrdersResponse">
        <xsd:complexType>
          <xsd:all>
            <xsd:element name="orders" type="xsd:string" />
          </xsd:all>
        </xsd:complexType>
      </xsd:element>

    </xsd:schema>
  </wsdl:types>

  <wsdl:message name="GetOrdersRequest">
    <wsdl:part name="parameters" element="os:GetOrders" />
  </wsdl:message>

  <wsdl:message name="GetOrdersResponse">
    <wsdl:part name="parameters" element="os:GetOrdersResponse" />
  </wsdl:message>

  <wsdl:portType name="GetOrdersPortType">
    <wsdl:operation name="GetOrders">
      <wsdl:input message="tns:GetOrdersRequest" />
      <wsdl:output message="tns:GetOrdersResponse" />
    </wsdl:operation>
  </wsdl:portType>

  <wsdl:binding name="GetOrdersBinding" type="tns:GetOrdersPortType">
    <soap:binding style="document"
       transport="http://schemas.xmlsoap.org/soap/http" />
    <wsdl:operation name="GetOrders">
      <soap:operation soapAction="" />
      <wsdl:input>
        <soap:body use="literal" />
      </wsdl:input>
      <wsdl:output>
        <soap:body use="literal" />
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>

  <wsdl:service name="OrdersService">
    <wsdl:port name="GetOrdersPort" binding="tns:GetOrdersBinding">
      <soap:address
         location="http://localhost:8080/svc/OrdersService/GetOrders" />
    </wsdl:port>
  </wsdl:service>

</wsdl:definitions>

我改变的事情:

• 将 xmlns:xsd 设置为 http://www.w3.org/2001/XMLSchema 而不是 http://www.w3 .org/1999/XMLSchema(1999版本已经很过时了)

• 从模式元素中删除了命名空间(GetOrders 而不是 o:GetOrders 和 GetOrdersResponse 而不是 os: GetOrdersResponse)(在元素或类型定义的 name 属性中不允许使用命名空间限定符)

• 为子元素 criteria 和 orders 使用了正确的类型:xsd:string 而不是 string

我同意，WSDL 一开始可能会很困难，但是，一旦您掌握了它，没有什么比定义明确的接口(interface)更好的了。如果我可以选择，我会毫不犹豫地选择 wsdl 而不是 json-REST-API。但我想这是一个品味问题 ;-)
