WS客户端:访问本地WSDL的正确途径是什么?
问题是我需要从我提供的文件构建Web服务客户端。 我已经将这个文件存储在本地文件系统中,并且当我将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并产生错误。 我搜索了网页,发现了以下文章,但我无法使其工作:
JAX-WS从jar中加载WSDL
http://www.java.net/forum/topic/glassfish/metro-and-jaxb/client-jar-cant-find-local-wsdl-0
http://blog.vinodsingh.com/2008/12/locally-packaged-wsdl.html
我正在使用NetBeans 6.1(这是一个遗留应用程序,我需要使用这个新的Web服务客户端进行更新)。 以下是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"));
}
/**
* @return
* returns SOAServiceSoap
*/
@WebEndpoint(name = "SOAServiceSOAP")
public SOAServiceSoap getSOAServiceSOAP() {
return super.getPort(new QName("http://soaservice.eci.ibm.com/", "SOAServiceSOAP"), SOAServiceSoap.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 SOAServiceSoap
*/
@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;
//classescomibmecisoaservice
//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将WSDL的副本放在web-inf / wsdl / client / SOAService中,所以我不想将它添加到META-INF中。 服务类位于WEB-INF / classes / com / ibm / eci / soaservice /中,并且baseurl变量包含文件系统的完整路径(c: path to the project ... soaservice)。 上面的代码引发了这个错误:
javax.xml.ws.WebServiceException:无法在以下位置访问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类来搜索 WEB-INF wsdl client SOAService.wsdl中的WSDL?
编辑 :我找到了这个其他链接 - http://jianmingli.com/wp/?cat=41,它表示将WSDL放入类路径。 我很惭愧地问:我如何将它放入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,请覆盖WSDL位置并将其设置为类似的内容
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提供WSDL。
您可以通过将wsdllocation选项传递给wsdl来执行此操作以获得java编译器。
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());
}
SOASERVICE_WSDL_LOCATION = url;
}
至
static {
URL url = null;
try {
URL baseUrl;
baseUrl = com.ibm.eci.soaservice.SOAService.class.getResource(".");
url = new URL(baseUrl, "http://localhost/wsdl/SOAService.wsdl");
} catch (MalformedURLException e) {
logger.warning("Failed to create URL for the wsdl Location: 'http://localhost/wsdl/SOAService.wsdl', retrying as a local file");
logger.warning(e.getMessage());
}
SOASERVICE_WSDL_LOCATION = url;
}
通知文件://在URL构造函数中更改为http://。
现在进入jax-ws-catalog.xml。 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并失败,因为没有这样的WSDL可用。
但是使用jax-ws-catalog.xml,只要它试图访问WSDL @,就可以将jax-ws重定向到本地打包的WSDL,
http://localhost/wsdl/SOAService.wsdl。
这里是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,当它需要加载WSDL时
http://localhost/wsdl/SOAService.wsdl它应该从本地路径wsdl / SOAService.wsdl加载它。
现在应该在哪里放置wsdl / SOAService.wsdl和jax-ws-catalog.xml? 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。
所以像这样的东西
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是从你的JAR中挑选出来的,并且避免在你的代码中使用硬编码的文件系统路径。

希望有所帮助
我们成功采用的另一种方法是使用wsimport(从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>
由于我们为具有多个WSDL的项目运行此脚本,因此脚本将动态解析$(wsdl.file)值,该值设置为/META-INF/wsdl/YourWebServiceName.wsdl相对于JavaSource位置(或/ src,取决于你如何设置项目)在构建过程中,WSDL和XSD文件被复制到这个位置并打包到JAR文件中(类似于上面Bhasakar描述的解决方案)
MyApp.jar
|__META-INF
|__wsdl
|__YourWebServiceName.wsdl
|__YourWebServiceName_schema1.xsd
|__YourWebServiceName_schmea2.xsd
注意:确保WSDL文件对所有导入的XSD使用相对引用,而不是http URL:
<types>
<xsd:schema>
<xsd:import namespace="http://valueobject.common.services.xyz.com/" schemaLocation="YourWebService_schema1.xsd"/>
</xsd:schema>
<xsd:schema>
<xsd:import namespace="http://exceptions.util.xyz.com/" schemaLocation="YourWebService_schema2.xsd"/>
</xsd:schema>
</types>
在生成的代码中,我们发现这个:
/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.2-b05-
* Generated source version: 2.1
*
*/
@WebServiceClient(name = "YourService", targetNamespace = "http://test.webservice.services.xyz.com/", wsdlLocation = "/META-INF/wsdl/YourService.wsdl")
public class YourService_Service
extends Service
{
private final static URL YOURWEBSERVICE_WSDL_LOCATION;
private final static WebServiceException YOURWEBSERVICE_EXCEPTION;
private final static QName YOURWEBSERVICE_QNAME = new QName("http://test.webservice.services.xyz.com/", "YourService");
static {
YOURWEBSERVICE_WSDL_LOCATION = com.xyz.services.webservice.test.YourService_Service.class.getResource("/META-INF/wsdl/YourService.wsdl");
WebServiceException e = null;
if (YOURWEBSERVICE_WSDL_LOCATION == null) {
e = new WebServiceException("Cannot find '/META-INF/wsdl/YourService.wsdl' wsdl. Place the resource correctly in the classpath.");
}
YOURWEBSERVICE_EXCEPTION = e;
}
public YourService_Service() {
super(__getWsdlLocation(), YOURWEBSERVICE_QNAME);
}
public YourService_Service(URL wsdlLocation, QName serviceName) {
super(wsdlLocation, serviceName);
}
/**
*
* @return
* returns YourService
*/
@WebEndpoint(name = "YourServicePort")
public YourService getYourServicePort() {
return super.getPort(new QName("http://test.webservice.services.xyz.com/", "YourServicePort"), YourService.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 YourService
*/
@WebEndpoint(name = "YourServicePort")
public YourService getYourServicePort(WebServiceFeature... features) {
return super.getPort(new QName("http://test.webservice.services.xyz.com/", "YourServicePort"), YourService.class, features);
}
private static URL __getWsdlLocation() {
if (YOURWEBSERVICE_EXCEPTION!= null) {
throw YOURWEBSERVICE_EXCEPTION;
}
return YOURWEBSERVICE_WSDL_LOCATION;
}
}
也许这也可能有帮助。 这只是一种不使用“目录”方法的不同方法。
非常感谢Bhaskar Karambelkar的回答,详细解释并解决了我的问题。 但是我也想用三个简单的步骤来回答那些急于解决问题的人的答案
wsdlLocation= "http://localhost/wsdl/yourwsdlname.wsdl"
在META-INF下创建一个xml文件jax-ws-catalog.xml,如下所示
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="system"> <system systemId="http://localhost/wsdl/yourwsdlname.wsdl" uri="wsdl/yourwsdlname.wsdl" /> </catalog>
现在打包你的罐子。 没有更多的参考本地目录,它都被打包并引用
