java中使用axis發布和調用webService及dom4j解析xml字符串

工作中需要調用webService服務，這里記錄一下如何在java中發布和調用webService。

 

需要的jar包：

 

 

 

webService服務端：

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.xml.ws.Endpoint;

@WebService
public class MyWebService {

    //@WebMethod(exclude = true)注解用於在webService中排除某方法
    @WebMethod(exclude = true)
    public String hello(String name) {
        System.out.println("hello:" + name);
        return "hello:" + name;
    }

    public String transcoding(String fileName, String fileId, String userId, String filePath, String newPath) {
        System.out.println("transcoding...");
        System.out.println("fileName:" + fileName);
        System.out.println("fileId:" + fileId);
        System.out.println("userId:" + userId);
        System.out.println("filePath:" + filePath);
        System.out.println("newPath:" + newPath);

        String result = "";
        result += "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
        result += "<root>";
        result += "<hbzm>";
        result += "<FileID>" + fileId + "</FileID>";
        result += "<FileName>" + fileName + "</FileName>";
        result += "<userid>" + userId + "</userid>";
        result += "<filepath>" + filePath + "</filepath>";
        result += "<newpath>" + newPath + "</newpath>";
        result += "<result>ACK</result>";
        result += "</hbzm>";
        result += "</root>";

        return result;
    }

    public static void main(String[] args) {
        /**
         * 參數1：服務的發布地址 參數2：服務的實現者
         */
        Endpoint.publish("http://localhost:8081/upload/transcoding", new MyWebService());
        System.out.println("webservice start success");
    }
}

            Document doc = DocumentHelper.parseText(transResult);

            System.out.println(e.elementText("result"));
