Creating a web-service client directly from the source
提问by benji
I am trying to generate the WS client jar directly from the @Webservice class(es).
我正在尝试直接从@Webservice 类生成 WS 客户端 jar。
Let's take this example :
让我们以这个例子为例：
package com.example.maven.jaxws.helloservice;
import javax.jws.WebService;
@WebService
public class Hello {
public String sayHello(String param) {
; return "Hello " + param;
}
}
I can generate a war file and use glassfish to serve this webservice, and from there I can use the glassfish WSDL URL to generate the client sources.
我可以生成一个 war 文件并使用 glassfish 来为这个 web 服务提供服务，然后我可以使用 glassfish WSDL URL 来生成客户端源。
What I am trying to do is to skip the glassfish part. From my maven project defining the webservice, I would like to use the jaxws-maven-plugin to create the client classes but I cannot find any way to specify the actual URL of the webservice.
我想要做的是跳过 glassfish 部分。从我定义 web 服务的 maven 项目中，我想使用 jaxws-maven-plugin 创建客户端类，但我找不到任何方法来指定 web 服务的实际 URL。
It should be possible right?
应该可以吧？

You should use <wsdlLocation>option to give the location of the service where the WSDL file is going to be available after deployment.
您应该使用<wsdlLocation>option 来指定部署后 WSDL 文件将可用的服务位置。
Using -wsdlLocation switch
There is another easy way to do it - just run wsimport with -wsdlLocation switch and provide the WSDL location value which is relative to the generated Service class and you need to put this WSDL file at this relative location.
使用 -wsdlLocation 开关
还有另一种简单的方法 - 只需使用 -wsdlLocation 开关运行 wsimport 并提供与生成的服务类相关的 WSDL 位置值，您需要将此 WSDL 文件放在此相对位置。

Creating a web service client application always starts with an existing WSDL file (unlike developing a web service provider) and, even if this is not the only way, I'd suggest to use the wsimporttool (see 5 Techniques for Creating Java Web Services from WSDLfor other options but I won't cover them).
创建 Web 服务客户端应用程序总是从现有的 WSDL 文件开始（与开发 Web 服务提供者不同），即使这不是唯一的方法，我也建议使用该wsimport工具（参见5 Techniques for Creating Java Web Services from WSDL用于其他选项，但我不会介绍它们）。
So, in your client project, add the following snippet to your pom.xml:
因此，在您的客户端项目中，将以下代码段添加到您的pom.xml：
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>wsimport</goal>
</goals>
<configuration>
<wsdlUrls>
<wsdlUrl>
http://localhost:8080/helloservice/HelloService?wsdl
</wsdlUrl>
</wsdlUrls>
<packageName>com.example.maven.jaxws.helloclient</packageName>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
<bulid>
The jaxws-maven-plugin:wsimportmojo is bound by default to the generate-sourceslife cycle phase so running any phase posterior to generate-sourceswill trigger the jaxws:wsimportgoal.
该jaxws-maven-plugin:wsimport魔咒默认绑定的generate-sources生命周期阶段，因此运行的任何阶段后，以generate-sources将触发jaxws:wsimport目标。
Note that this is really a minimal configuration. If you want more details/control, check the documentation of the wsimportmojo.
请注意，这实际上是一个最小配置。如果您想要更多详细信息/控制，请查看wsimportmojo的文档。
For example, to use files instead of URLs for the WSDL (and to generate Java code in a location more compliant with maven best practices), use:
例如，要为 WSDL 使用文件而不是 URL（并在更符合 maven 最佳实践的位置生成 Java 代码），请使用：
<configuration>
<sourceDestDir>${project.build.directory}/generated-sources/wsimport</sourceDestDir>
<wsdlDirectory>${basedir}/src/wsdl</wsdlDirectory>
<wsdlFiles>
<wsdlFile>foo.wsdl</wsdlFile>
<wsdlFile>bar.wsdl</wsdlFile>
</wsdlFiles>
...
</configuration>
Update:To invoke a pre-configured stub (using the endpoint address from the WSDL), the code is:
更新：要调用预先配置的存根（使用来自 WSDL 的端点地址），代码是：
Hello port = new HelloService().getHelloPort();
String result = port.sayHello("Duke!");
In order to invoke an endpoint whose address is different from the one specified in the WSDL, define the new endpoint URL and the QName:
为了调用地址与 WSDL 中指定的地址不同的端点，请定义新的端点 URL 和 QName：
URL endpoint_new = new URL( "NEW_ADDRESS_HERE" );
QName qname = new QName( "http://"+"ORIGINAL_PACKAGE", "SERVICENAME" );
Hello port = new HelloService( endpoint_new, qname ).getHelloPort();
where ORIGINAL_PACKAGEis the package where the service published in, SERVICENAMEis the name of the service we need, for example, HelloService.
其中ORIGINAL_PACKAGE是发布服务所在的包，SERVICENAME是我们需要的服务的名称，例如HelloService.
