Web Service

2014/2/23

  1. 先建立要透過 Web Service 呼叫的 method

    package tw.shunyi.ws.server;

import javax.jws.WebService;

@WebService
public class CircleFunctions {

    public double getArea(double r) {
        return java.lang.Math.PI * (r * r);
    }

    public double getCircumference(double r) {
        return 2 * java.lang.Math.PI * r;
    }
}

  2. 建立 server 端程式

    package tw.shunyi.ws.server;

import javax.xml.ws.Endpoint;

public class Server {

    public static void main(String[] args) {

        Endpoint.publish(
                "http://localhost:8080/SimpleWebService/circlefunctions",
                new CircleFunctions());

    }
}

  3. 啟動 web server

    3.1. 程式會動態產生 wrapper class

    2014/2/23 上午 09:11:19 com.sun.xml.internal.ws.model.RuntimeModeler getRequestWrapperClass
資訊: Dynamically creating request wrapper Class tw.shunyi.ws.server.jaxws.GetArea
2014/2/23 上午 09:11:19 com.sun.xml.internal.ws.model.RuntimeModeler getResponseWrapperClass
資訊: Dynamically creating response wrapper bean Class tw.shunyi.ws.server.jaxws.GetAreaResponse
2014/2/23 上午 09:11:19 com.sun.xml.internal.ws.model.RuntimeModeler getRequestWrapperClass
資訊: Dynamically creating request wrapper Class tw.shunyi.ws.server.jaxws.GetCircumference
2014/2/23 上午 09:11:19 com.sun.xml.internal.ws.model.RuntimeModeler getResponseWrapperClass
資訊: Dynamically creating response wrapper bean Class tw.shunyi.ws.server.jaxws.GetCircumferenceResponse

    3.2. 可以執行以下指令來產生 wrapper class, 避免每次重啟 server 都要動態產生

    wsgen -verbose -cp . tw.shunyi.ws.server.CircleFunctions

  4. 執行以下指令產生給 client site 用的檔案

    wsimport -p tw.shunyi.ws.client -s src -d bin -verbose http://localhost:8080/SimpleWebService/circlefunctions?WSDL

  5. 建立 client 端程式

    package tw.shunyi.ws.client;

public class Client {
    private static CircleFunctionsService service;

    public static void main(String[] args) {
        service = new CircleFunctionsService();
        CircleFunctions port = service.getCircleFunctionsPort();
        System.out.println(port.getArea(1.0));
    }
}

  6. 執行結果
