JAX-WS客户端:访问本地WSDL的正确途径是什么？

81 java client netbeans jax-ws

问题是我需要从我提供的文件构建一个Web服务客户端.我已将此文件存储在本地文件系统中,并且在将WSDL文件保存在正确的文件系统文件夹中时,一切都很好.当我将其部署到服务器或从文件系统文件夹中删除WSDL时,代理无法找到WSDL并出现错误.我在网上搜索过,但我发现了以下帖子但是我无法使它工作:
JAX-WS从jar加载WSDL

http://blog.vinodsingh.com/2008/12/locally-packaged-wsdl.html

我正在使用NetBeans 6.1(这是我要用这个新的Web服务客户端更新的遗留应用程序).下面是JAX-WS代理类:

    @WebServiceClient(name = "SOAService", targetNamespace = "http://soaservice.eci.ibm.com/", wsdlLocation = "file:/C:/local/path/to/wsdl/SOAService.wsdl")
public class SOAService
    extends Service
{

    private final static URL SOASERVICE_WSDL_LOCATION;
    private final static Logger logger = Logger.getLogger(com.ibm.eci.soaservice.SOAService.class.getName());

    static {
        URL url = null;
        try {
            URL baseUrl;
            baseUrl = com.ibm.eci.soaservice.SOAService.class.getResource(".");
            url = new URL(baseUrl, "file:/C:/local/path/to/wsdl/SOAService.wsdl");
        } catch (MalformedURLException e) {
            logger.warning("Failed to create URL for the wsdl Location: 'file:/C:/local/path/to/wsdl/SOAService.wsdl', retrying as a local file");
            logger.warning(e.getMessage());
        }
        SOASERVICE_WSDL_LOCATION = url;
    }

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

    public SOAService() {
        super(SOASERVICE_WSDL_LOCATION, new QName("http://soaservice.eci.ibm.com/", "SOAService"));
    }

    /**

     *     returns SOAServiceSoap
     */
    @WebEndpoint(name = "SOAServiceSOAP")
    public SOAServiceSoap getSOAServiceSOAP() {
        return super.getPort(new QName("http://soaservice.eci.ibm.com/", "SOAServiceSOAP"), SOAServiceSoap.class);
    }

    /**

    @WebEndpoint(name = "SOAServiceSOAP")
    public SOAServiceSoap getSOAServiceSOAP(WebServiceFeature... features) {
        return super.getPort(new QName("http://soaservice.eci.ibm.com/", "SOAServiceSOAP"), SOAServiceSoap.class, features);
    }

这是我使用代理的代码:

   WebServiceClient annotation = SOAService.class.getAnnotation(WebServiceClient.class);
   // trying to replicate proxy settings
   URL baseUrl = com.ibm.eci.soaservice.SOAService.class.getResource("");//note : proxy uses "."
   URL url = new URL(baseUrl, "/WEB-INF/wsdl/client/SOAService.wsdl");
   //URL wsdlUrl = this.getClass().getResource("/META-INF/wsdl/SOAService.wsdl"); 
   SOAService serviceObj = new SOAService(url, new QName(annotation.targetNamespace(), annotation.name()));
   proxy = serviceObj.getSOAServiceSOAP();
   /* baseUrl;

   //classes\com\ibm\eci\soaservice
   //URL url = new URL(baseUrl, "../../../../wsdl/SOAService.wsdl");

   proxy = new SOAService().getSOAServiceSOAP();*/
   //updating service endpoint 
   Map<String, Object> ctxt = ((BindingProvider)proxy ).getRequestContext();
   ctxt.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192);
   ctxt.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, WebServiceUrl);

NetBeans在Web-inf/wsdl/client/SOAService中放置了WSDL的副本,因此我也不想将它添加到META-INF中.服务类在WEB-INF/classes/com/ibm/eci/soaservice /中,baseurl变量包含文件系统的完整路径(c:\ path\to\the\project ...\soaservice).上面的代码引发了错误:

javax.xml.ws.WebServiceException:无法访问WSDL:file:/WEB-INF/wsdl/client/SOAService.wsdl.它失败了:\ WEB-INF\wsdl\client\SOAService.wsdl(找不到路径)

那么,首先,我应该更新代理类的wsdllocation吗？那么如何告诉WEB-INF/classes/com/ibm/eci/soaservice中的SOAService类在\ WEB-INF\wsdl\client\SOAService.wsdl中搜索WSDL？

编辑:我发现了另一个链接 - http://jianmingli.com/wp/?cat=41,它说将WSDL放入类路径中.我很惭愧地问:我怎么把它放到web应用程序类路径中？

最好的选择是使用jax-ws-catalog.xml

编译本地WSDL文件时,覆盖WSDL位置并将其设置为类似的位置

http://localhost/wsdl/SOAService.wsdl

不要担心这只是一个URI而不是一个URL,这意味着您不必在该地址上提供WSDL.
您可以通过将wsdllocation选项传递给wsdl到java编译器来完成此操作.

这样做会改变你的代理代码 

static {
    URL url = null;
    try {
        URL baseUrl;
        baseUrl = com.ibm.eci.soaservice.SOAService.class.getResource(".");
        url = new URL(baseUrl, "file:/C:/local/path/to/wsdl/SOAService.wsdl");
    } catch (MalformedURLException e) {
        logger.warning("Failed to create URL for the wsdl Location: 'file:/C:/local/path/to/wsdl/SOAService.wsdl', retrying as a local file");
        logger.warning(e.getMessage());

通知文件://在URL构造函数中更改为http://.

现在出现在jax-ws-catalog.xml中.如果没有jax-ws-catalog.xml,jax-ws确实会尝试从该位置加载WSDL

http://localhost/wsdl/SOAService.wsdl
并且失败,因为没有这样的WSDL可用.

但是使用jax-ws-catalog.xml,只要它尝试访问WSDL @,就可以将jax-ws重定向到本地打包的WSDL. 

http://localhost/wsdl/SOAService.wsdl
.

这是jax-ws-catalog.xml 

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="system">
        <system systemId="http://localhost/wsdl/SOAService.wsdl"
                uri="wsdl/SOAService.wsdl"/>
    </catalog>

你正在做的是告诉jax-ws什么时候需要加载WSDL 

http://localhost/wsdl/SOAService.wsdl
,它应该从本地路径wsdl/SOAService.wsdl加载它.

现在你应该把wsdl/SOAService.wsdl和jax-ws-catalog.xml放在哪里？这是百万美元的问题不是吗？
它应该位于应用程序jar的META-INF目录中.

所以这样的事情 

ABCD.jar  
|__ META-INF    
    |__ jax-ws-catalog.xml  
    |__ wsdl  
        |__ SOAService.wsdl

这样,您甚至不必覆盖访问代理的客户端中的URL.WSDL是从JAR中获取的,您可以避免在代码中使用硬编码的文件系统路径.

有关jax-ws-catalog.xml的更多信息 http://jax-ws.java.net/nonav/2.1.2m1/docs/catalog-support.html

希望有所帮助

  • 对于Web应用程序,正确的位置是WEB-INF/classes/META-INF (11认同)

我们成功采取的另一种方法是使用wsimport(来自Ant,作为Ant任务)生成WS客户端代理代码,并指定wsdlLocation属性.

<wsimport debug="true" keep="true" verbose="false" target="2.1" sourcedestdir="${generated.client}" wsdl="${src}${wsdl.file}" wsdlLocation="${wsdl.file}">
</wsimport>

因为我们为具有多个WSDL的项目运行此脚本,所以该脚本动态地解析$(wsdl.file}值,该值相对于JavaSource位置(或/ src,设置为/META-INF/wsdl/YourWebServiceName.wsdl)取决于您如何设置项目.)在构建过程中,WSDL和XSD文件被复制到此位置并打包在JAR文件中.(类似于上面Bhasakar描述的解决方案)

MyApp.jar
|__META-INF
   |__wsdl
      |__YourWebServiceName.wsdl

也许这也可能有所帮助.这只是一种不使用"目录"方法的不同方法.

对于那些仍然在这里寻求解决方案的人来说，最简单的解决方案是使用<wsdlLocation>，而不更改任何代码。工作步骤如下：

  1. 将您的 wsdl 放入资源目录，例如：src/main/resource

  2. 在pom文件中，添加wsdlDirectory和wsdlLocation（不要错过wsdlLocation开头的/），如下所示。wsdlDirectory 用于生成代码，而 wsdlLocation 在运行时用于创建动态代理。

    <wsdlDirectory>src/main/resources/mydir</wsdlDirectory>
<wsdlLocation>/mydir/my.wsdl</wsdlLocation>

  3. 然后在你的java代码中（使用无参数构造函数）：
