WebService(1)-优快云博客

新建web项目，然后创建一个WEB服务：

@WebService()
public class Hello {
    @WebMethod(operationName = "sayHi")
    public String sayHi(@WebParam(name = "name")String name) {
       return "Hi " + name;
    }
}

可以在源图上右键，选Web服务--添加操作，也可以在设计图上直接添加操作。@WebService标注表明该类是一个web服务，展现给web服务客户端的业务方法必须使用@WebMethod标注来表示。打包部署该web应用，web服务自动会发布。可以在glassfish应用服务器上找到该web服务，直接测试或者查看服务器生成的WSDL

也可以编写客户端测试，新建一个普通的java项目，在项目上右键，选择新建--Web服务客户端，在弹出窗口中指定WebService项目或者WSDL url，点击完成。在源代码上右键，选择Web服务客户端资源--调用Web服务操作，在弹出窗口中选择sayHi操作，点确定，测试代码自动生成：

public class Main {

    public static void main(String[] args) {

        try {

            webservice.HelloService service = new webservice.HelloService();
            webservice.Hello port = service.getHelloPort();

            java.lang.String name = "Tom";
            java.lang.String result = port.sayHi(name);
            System.out.println("Result = " + result);
        } catch (Exception ex) {
            // TODO handle custom exceptions here
        }
    }
}

运行该客户端，结果将会输出
