无法从 classpath:wsdl 初始化默认 wsdl

问题描述

我正在通过一个示例来了解 SOAP 的工作原理。我已经使用 Apache cxf 从 wsdl 生成了代码，并且可以记录 SOAP Web 服务请求和响应。显然一切正常。我有一个设置相对路径的问题。我已遵循此解决方案 How to avoid the need to specify the WSDL location in a CXF or JAX-WS generated webservice client?，但无法解决控制台上的日志错误。

控制台上的错误信息：

jun 03,2021 2:17:38 PM io.codejournal.maven.wsdl2java.NumberConversion <clinit>
INFO: Can not initialize the default wsdl from classpath:wsdl/dataaccess-numberconversion.wsdl

这是我的 pom.xml：

我的服务类：

@WebServiceClient(name = "NumberConversion",wsdlLocation = "classpath:wsdl/dataaccess-numberconversion.wsdl",targetNamespace = "http://www.dataaccess.com/webservicesserver/")
public class NumberConversion extends Service {

    public final static URL WSDL_LOCATION;

    public final static QName SERVICE = new QName("http://www.dataaccess.com/webservicesserver/","NumberConversion");
    public final static QName NumberConversionSoap = new QName("http://www.dataaccess.com/webservicesserver/","NumberConversionSoap");
    public final static QName NumberConversionSoap12 = new QName("http://www.dataaccess.com/webservicesserver/","NumberConversionSoap12");
    static {
        URL url = NumberConversion.class.getClassLoader().getResource("wsdl/dataaccess-numberconversion.wsdl");
        if (url == null) {
            java.util.logging.Logger.getLogger(NumberConversion.class.getName())
                .log(java.util.logging.Level.INFO,"Can not initialize the default wsdl from {0}","classpath:wsdl/dataaccess-numberconversion.wsdl");
        }
        WSDL_LOCATION = url;
    }

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

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

    public NumberConversion() {
        super(WSDL_LOCATION,SERVICE);
    }

    public NumberConversion(WebServiceFeature ... features) {
        super(WSDL_LOCATION,SERVICE,features);
    }

    public NumberConversion(URL wsdlLocation,WebServiceFeature ... features) {
        super(wsdlLocation,QName serviceName,serviceName,features);
    }
   
    /**
     *
     * @return
     *     returns NumberConversionSoapType
     */
    @WebEndpoint(name = "NumberConversionSoap")
    public NumberConversionSoapType getNumberConversionSoap() {
        return super.getPort(NumberConversionSoap,NumberConversionSoapType.class);
    }

    /**
     *
     * @param features
     *     A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy.  Supported features not in the <code>features</code> parameter will have their default values.
     * @return
     *     returns NumberConversionSoapType
     */
    @WebEndpoint(name = "NumberConversionSoap")
    public NumberConversionSoapType getNumberConversionSoap(WebServiceFeature... features) {
        return super.getPort(NumberConversionSoap,NumberConversionSoapType.class,features);
    }


    /**
     *
     * @return
     *     returns NumberConversionSoapType
     */
    @WebEndpoint(name = "NumberConversionSoap12")
    public NumberConversionSoapType getNumberConversionSoap12() {
        return super.getPort(NumberConversionSoap12,NumberConversionSoapType.class);
    }

    /**
     *
     * @param features
     *     A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy.  Supported features not in the <code>features</code> parameter will have their default values.
     * @return
     *     returns NumberConversionSoapType
     */
    @WebEndpoint(name = "NumberConversionSoap12")
    public NumberConversionSoapType getNumberConversionSoap12(WebServiceFeature... features) {
        return super.getPort(NumberConversionSoap12,features);
    }

}

当我运行此代码 URL url = NumberConversion.class.getClassLoader().getResource("wsdl/dataaccess-numberconversion.wsdl"); 时，我会得到一个空值。 NumberConversion.class.getClassLoader() 调用的是错误的路径，因为这个类在另一个包中。

知道如何以正确的方式设置吗？

解决方法

您的 <wsdlOption> 不匹配，在 <wsdl> 和 <wsdlLocation> 值之间。

<wsdl>${basedir}/src/main/resources/dataaccess-numberconversion.wsdl</wsdl>
<wsdlLocation>classpath:wsdl/dataaccess-numberconversion.wsdl</wsdlLocation>

第一行表示该文件位于类路径的根目录中，但在第二行中，您说它位于名为 wsdl 的子路径上。两者都不可能是真的。

因此将您的代码更改为：

<wsdl>${basedir}/src/main/resources/wsdl/dataaccess-numberconversion.wsdl</wsdl>
<wsdlLocation>classpath:wsdl/dataaccess-numberconversion.wsdl</wsdlLocation>

或：

<wsdl>${basedir}/src/main/resources/dataaccess-numberconversion.wsdl</wsdl>
<wsdlLocation>classpath:dataaccess-numberconversion.wsdl</wsdlLocation>

/src/main/resources/ 和 classpath: 之后的内容必须匹配。

无论您选择哪种变体，请确保：

WSDL 文件位于项目的 /src/main/resources/ 文件夹中的适当位置（直接在该文件夹中或在 wsdl 子文件夹中）。
您的所有代码也反映了正确的类路径路径（在类路径的根目录上或在名为 wsdl 的子包内）；
在打包 JAR 文件后，您将其解压缩并查看内部以查看 WSDL 文件是否位于 JAR 内的正确位置（直接位于根目录或 aa wsdl 子文件夹中）。
