一个简单的webService

1.创建接口类

@WebService
public interface Hello {
    String sayHi(@WebParam(name="name")String name);
}

2.实现接口类

@WebService(endpointInterface = "com.test.Hello",
        serviceName = "Hello")
public class HelloImpl implements Hello {
    public String sayHi(String name) {
        return "hello,"+name;
    }
}

3.发布

public class ServiceMain {

    public static void main(String[] args) throws Exception{
        System.out.print("Starting Service...");
        String address = "http://localhost:8888/hello";
        HelloImpl helloImpl = new HelloImpl();
        Endpoint.publish(address,helloImpl);
    }
}

4.访问：http://localhost:8888/hello?wsdl，如下成功

问题：

执行main方法时候有可能出现以下错误，据说是JDK版本所致：

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

Process finished with exit code 1

解决方法：

给接口类的sayHi()方法加上：  

@SOAPBinding(style=SOAPBinding.Style.RPC)
