我必须准备一个 web 服务来接受一个已经定义的 wsdl 结构。我跟着教程found here , 带有测试项目的源代码 downloadable here .

对于这样的 xsd:

<xs:element name="getCountryRequest">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="name" type="xs:string"/>
        </xs:sequence>
    </xs:complexType>
</xs:element>

<wsdl:binding name="CountriesPortSoap11" type="tns:CountriesPort">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="getCountry">
        <soap:operation soapAction=""/>
        <wsdl:input name="getCountryRequest">
            <soap:body use="literal"/>
        </wsdl:input>
        <wsdl:output name="getCountryResponse">
            <soap:body use="literal"/>
        </wsdl:output>
    </wsdl:operation>
</wsdl:binding>

<xs:element name="getCountry">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="name" type="xs:string"/>
        </xs:sequence>
    </xs:complexType>
</xs:element>

<wsdl:binding name="CountriesPortSoap11" type="tns:CountriesPort">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="getCountry">
        <soap:operation soapAction=""/>
        <wsdl:output name="getCountryResponse">
            <soap:body use="literal"/>
        </wsdl:output>
    </wsdl:operation>
</wsdl:binding>

最佳答案

根据 official Spring WS documentation ，请求/响应后缀是用于自动确定请求/响应并因此生成预期 WSDL 的默认后缀。

The DefaultWsdl11Definition which builds a WSDL from a XSD schema. This definition iterates over all element elements found in the schema, and creates a message for all elements. Next, it creates WSDL operation for all messages that end with the defined request or response suffix. The default request suffix is Request; the default response suffix is Response, though these can be changed by setting the requestSuffix and responseSuffix properties, respectively.

wsdl11Definition.setRequestSuffix("your-new-prefix-here");

wsdl11Definition.setRequestSuffix("");

Basically, the problem is this:
We have to differentiate which schema elements are wsdl messages, and which aren't.
Of all wsdl messages, we have to figure out which are input (request) messages.
Of all wsdl messages, we have to figure out which are output (response) messages.

The DefaultWsdl11Definition figures this out by suffixes. Or, more specifically, it delegates to a SuffixBasedMessagesProvider and SuffixBasedPortTypesProvider to do so.
So if you have some other preferred way of determining what makes an input/output message, you will have to write your own messagesprovider and or porttypesprovider.

Simply put: there is no generic way for Spring-WS to determine what makes up a request and a response, rather than using suffixes.

package hello;

public class MySuffixBasedMessagesProvider extends SuffixBasedMessagesProvider {

    protected String requestSuffix = DEFAULT_REQUEST_SUFFIX;

    public String getRequestSuffix() {
        return this.requestSuffix;
    }

    public void setRequestSuffix(String requestSuffix) {
        this.requestSuffix = requestSuffix;
    }

    @Override
    protected boolean isMessageElement(Element element) {
        if (isMessageElement0(element)) {
            String elementName = getElementName(element);
            Assert.hasText(elementName, "Element has no name");
            return elementName.endsWith(getResponseSuffix())
                    || (getRequestSuffix().isEmpty() ? true : elementName.endsWith(getRequestSuffix()))
                    || elementName.endsWith(getFaultSuffix());
        }
        return false;
    }

    protected boolean isMessageElement0(Element element) {
        return "element".equals(element.getLocalName())
                && "http://www.w3.org/2001/XMLSchema".equals(element.getNamespaceURI());
    }
}

package hello;

public class MySuffixBasedPortTypesProvider extends SuffixBasedPortTypesProvider {

    private String requestSuffix = DEFAULT_REQUEST_SUFFIX;

    public String getRequestSuffix() {
        return requestSuffix;
    }

    public void setRequestSuffix(String requestSuffix) {
        this.requestSuffix = requestSuffix;
    }

    @Override
    protected String getOperationName(Message message) {
        String messageName = getMessageName(message);
        String result = null;
        if (messageName != null) {
            if (messageName.endsWith(getResponseSuffix())) {
                result = messageName.substring(0, messageName.length() - getResponseSuffix().length());
            } else if (messageName.endsWith(getFaultSuffix())) {
                result = messageName.substring(0, messageName.length() - getFaultSuffix().length());
            } else if (messageName.endsWith(getRequestSuffix())) {
                result = messageName.substring(0, messageName.length() - getRequestSuffix().length());
            }
        }
        return result;
    }

    @Override
    protected boolean isInputMessage(Message message) {
        String messageName = getMessageName(message);

        return messageName != null && !messageName.endsWith(getResponseSuffix());
    }

    private String getMessageName(Message message) {
        return message.getQName().getLocalPart();
    }

关于java - 请求元素不以 'Request'结尾时spring-ws生成的wsdl无效，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34525587/
