java - 在 Eclipse : "wsdl:operation was not a request/response or one-way operation" 中验证期间出现奇怪的 WSDL 警告

Question

我正在编写一个 WSDL 文件，但我无法摆脱来自 Eclipse validator 的这个警告:

WS-I: (BP2208) wsdl:operation was not a request/response or one-way operation.

这是我写的 WSDL 源代码:

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

<definitions name="Master"
    targetNamespace="http://pad.polito.it/ACSAuth"
    xmlns:tns="http://pad.polito.it/ACSAuth"

    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
    xmlns="http://schemas.xmlsoap.org/wsdl/">

    <types>
        <xs:schema 
        xmlns:xs="http://www.w3.org/2001/XMLSchema" version="1.0"
        targetNamespace="http://pad.polito.it/ACSAuth"
        xmlns:tns="http://pad.polito.it/ACSAuth">

            <xs:element name="AccessDB" type="tns:AccessDBType">
            <!-- OMITTED COMPLEX TYPE AccessDBType -->

            <xs:element name="passThrough" type="tns:passThroughType"/>
            <!-- OMITTED COMPLEX TYPE passThroughType -->

        </xs:schema>
    </types>

    <message name="updatedDB">
        <part name="db" element="tns:AccessDB"/>
    </message>

    <message name="passThroughNotice">
        <part name="info" element="tns:passThrough"/>
    </message>

    <portType name="myPorts">
        <operation name="updateManager">
            <output name="newUpdate" message="tns:updatedDB"/>
        </operation>
        <operation name="noticeManager">
            <input name="newNotice" message="tns:passThroughNotice"/>
        </operation>
    </portType>

    <binding name="myBindings" type="tns:myPorts">
        <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
        <operation name="updateManager">
            <soap:operation soapAction="" />
            <output>
                <soap:body use="literal"/>
            </output>
        </operation>
        <operation name="noticeManager">
            <soap:operation soapAction="" />
            <input>
                <soap:body use="literal"/>
            </input>
        </operation>
    </binding>

    <service name="MyServices">
        <port name="ACSAuth" binding="tns:myBindings">
            <soap:address location="http://localhost:8181/ACSAuth"/>
        </port>
    </service>

</definitions>

我相信问题的根源是操作“updateManager”，但我不知道如何修复它。有人能帮助我吗？提前谢谢你。

端点可以支持 4 种类型的操作。来自WSDL specs :

WSDL has four transmission primitives that an endpoint can support:

• One-way. The endpoint receives a message.
• Request-response. The endpoint receives a message, and sends a correlated message.
• Solicit-response. The endpoint sends a message, and receives a correlated message.
• Notification. The endpoint sends a message.

WS-I Profile 似乎有一条规则只支持其中的两个。 From WS-I, Test Assertion: BP2208 :

Context:
For a candidate wsdl:operation in a wsdl:portType definition

Assertion Description:
The wsdl:operation element is either a WSDL request/response or a one-way operation (no Notification or Sollicit-Response).

Failure Message:
wsdl:operation was not a request/response or one-way operation.

您的 updateManager 操作是一个 Notification 并从这里发出警告。

清除错误靠你了interoperability compliance需要。您可以忽略该警告(这样您的服务将不会 100% 兼容互操作性)，也可以通过更改操作类型(取决于您的应用程序)来修复它。
