java - 在 Java 中创建非常简单的 Web 服务时出现运行时建模器错误

Question

我是 java 网络服务的初学者。

我创建了一个简单的网络服务，并尝试按如下方式发布它

 Endpoint.publish("http://localhost:8080/HelloWeb", new HelloWeb());

报错如下

Exception in thread "main" com.sun.xml.internal.ws.model.RuntimeModelerException: runtime modeler error: Wrapper class com.ravi.jaxws.SayGreeting is not found. Have you run APT to generate them?

知道这里出了什么问题。

我的网络服务类非常简单，代码如下:

    @WebService
@SOAPBinding(style = Style.DOCUMENT, use=Use.LITERAL)
public class HelloWeb {

    @WebMethod
    public String sayHello(String name){
        return "Hello "+name;
    }
}

首先调用 wsgen 实用程序。此实用程序生成各种工件，即方法 Endpoint.publish 生成服务的 WSDL 所需的 java 类型。这是示例 在工作目录运行

  wsgen -keep -cp  package.HelloWeb
