我正在尝试了解 jax-ws 并创建了一个简单的自下而上 HelloWorld 网络服务来训练自己：

import org.jboss.annotation.ejb.LocalBinding;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;

@WebService(serviceName = "HelloWorldWebServiceExperiment",
    portName = "HelloWorldPort",
    name = "HelloWorld")
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, 
    use = SOAPBinding.Use.LITERAL, 
    parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
@Stateless
@Remote
@LocalBinding(jndiBinding = "training.webservice.HelloWorldWebServiceRemote/local")

public class HelloWorldWebServiceBean {
    private static final String HELLO_WORLD = "Hello World";
    @WebMethod
    public String helloWorld() {
        return HELLO_WORLD;
    }
}

当我部署这个网络服务时，我可以访问 wsdl，所以这似乎工作正常。然后我尝试生成一个 web 服务客户端。为此，我需要创建存根，我尝试使用 maven 插件 jaxws-maven-plugin 创建它。这是我的 pom.xml：

编辑（为了精确）：当我尝试在另一个项目中使用存根存档来创建 web 客户端时，（我使用 intellij idea 执行此操作），idea 会自动从我的 maven 存储库中找到该文件并建议给我，生成以下依赖项：

 <dependency>
        <groupId>training.webservice</groupId>
        <artifactId>HelloWorldWebServiceExperiment</artifactId>
        <version>1.0-SNAPSHOT-wsclient</version>
 </dependency>

但是，实际上没有一个生成的 .java 文件可以在代码中导入和使用！例如，想法在使用或导入时失败

import training.webservice.HelloWorld;

private training.webservice.HelloWorld helloWorld;

带有错误消息“无法解析符号'HelloWorld'”我做错了什么？这是否与我的存根仅包含 .java 文件但没有 .class 文件的事实有关？显然，插件 jaxws-maven-plugin 使用 -xnocompile 标志运行 wsimport，但我无法弄清楚如何配置 maven 不这样做，没有任何选项保留，destDir 或 sourceDestDir 对此有任何影响！还是这完全无关紧要，因为导入存根的项目应该能够自己编译它们，而问题出在其他地方？任何帮助将不胜感激！

我找到了一个临时工作：我手动生成了一个客户端存根 .jar 文件。由于我的公司仍在使用 Java 1.5，我必须安装 Metro 才能使用 wsimport（我选择了 1.6.2 版），然后我可以调用：

wsimport target/generated-sources/wsdl/HelloWorldWebServiceExperiment.wsdl -d target/generated-sources/wsdl/ -keep

之后我有 .java 和 .class 文件，我可以手动打包到 .jar 文件中，然后我将该 .jar 移动到我的 webservice 客户端项目的 ressource 文件夹中，并将依赖项手动添加到我的 pom.xml 中：

        <dependency>
            <groupId>training.webservice</groupId>
            <artifactId>HelloWorldWebServiceExperiment</artifactId>
            <version>1.0</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/client.jar</systemPath>
    </dependency>

我更喜欢从 maven 自动构建和部署，我现在确定问题必须出在我的 maven 设置中，但是我仍然不知道如何做得更好。至少我现在可以继续处理 web 服务客户端，稍后再重新讨论这个问题！
