使用cxf wsdl2java生成的Web服务时出现java错误“无法满足任何策略替代方案”

Question

我正在尝试基于wsdl文件构建一个web服务客户端。该客户机用于使用Spring和Maven构建的java webapp。我使用了cxf 2.4.9作为eclipse插件，从wsdl文件生成java代码。web服务需要使用用户名和密码，以便wsdl文件包含用户名令牌策略

当我测试生成的服务时，我得到以下错误：

org.apache.cxf.ws.policy.PolicyException: None of the policy alternatives can be satisfied.

以下是web服务的代码片段：

wsdl文件的策略部分：

<wsp:UsingPolicy wssutil:Required="true" />
<wsp:Policy wssutil:Id="policy">
    <ns0:SupportingTokens
        xmlns:ns0="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200512">
        <wsp:Policy>
            <ns0:UsernameToken
                ns0:IncludeToken="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200512/IncludeToken/AlwaysToRecipient">
                <wsp:Policy>
                    <ns0:WssUsernameToken11 />
                </wsp:Policy>
            </ns0:UsernameToken>
        </wsp:Policy>
    </ns0:SupportingTokens>
</wsp:Policy>

生成的服务：

@WebServiceClient(name = "EURLexWebService", 
              wsdlLocation = "http://eur-lex.europa.eu/EURLexWebService?wsdl",
              targetNamespace = "http://eur-lex.europa.eu/search") 
public class EURLexWebService extends Service {

public final static URL WSDL_LOCATION;

public final static QName SERVICE = new QName("http://eur-lex.europa.eu/search", "EURLexWebService");
public final static QName EURLexWebServicePort = new QName("http://eur-lex.europa.eu/search", "EURLexWebServicePort");
static {
    URL url = null;
    try {
        url = new URL("http://eur-lex.europa.eu/EURLexWebService?wsdl");
    } catch (MalformedURLException e) {
        java.util.logging.Logger.getLogger(EURLexWebService.class.getName())
            .log(java.util.logging.Level.INFO, 
                 "Can not initialize the default wsdl from {0}", "http://eur-lex.europa.eu/EURLexWebService?wsdl");
    }
    WSDL_LOCATION = url;
}

public EURLexWebService(URL wsdlLocation) {
    super(wsdlLocation, SERVICE);
}

public EURLexWebService(URL wsdlLocation, QName serviceName) {
    super(wsdlLocation, serviceName);
}

...

}

用于调用Web服务的代码：

URL wsdlURL = EURLexWebService.WSDL_LOCATION;
File wsdlFile = getWsdlFile();
if (wsdlFile.exists()) {
     wsdlURL = wsdlFile.toURI().toURL();
}

EURLexWebService ss = new EURLexWebService(wsdlURL, EURLexWebService.SERVICE);
EURLexWebServiceProvider port = ss.getEURLexWebServicePort();

Map ctx = ((BindingProvider)port).getRequestContext();
ctx.put("ws-security.username", "mylogin");
ctx.put("ws-security.password", "mypassword");

doQuery(port);

最后是完整的stackstrace：

我读了一些关于这个话题的文章。其中有一个代码片段，我将用户名和密码放在请求上下文映射中，但它不起作用

我用SoapUI测试了web服务，它运行正常，所以问题似乎出在我的java代码上

任何帮助都将不胜感激

Answer 1

问题解决了！首先，wsdl文件中有一个错误

命名空间http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200512不正确，必须用http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702或http://schemas.xmlsoap.org/ws/2005/07/securitypolicy替换

由于wsdl文件中定义了一个策略，填充requestContext映射是正确的做法

最后，在doQuery(EurlexWebServiceProvider port)方法中，我构建了一个SearchRequest对象，它是webservice调用的一个参数，我忘了设置这个对象的一个属性，这是请求有效所必需的
