第四种方式

通过urlConnection连接webservicce

1.服务必须启动

2..

ackage cn.itcast.service.uriconnection;


import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;


public class App2 {


public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub

String wsUrl = "http://localhost:5084/hello";
URL url = new URL(wsUrl);
URLConnection conn = url.openConnection();
HttpURLConnection con = (HttpURLConnection) conn;
// 设置请求方式
con.setDoInput(true);
con.setDoOutput(true);
con.setRequestMethod("POST");
con.setRequestProperty("content-type", "text/xml;charset=UTF-8");


// 手动构造请求体
String requestBody = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" "+


" xmlns:q0=\"http://service.itcast.cn/\"    xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" "+  
"  xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"> " +
"<soapenv:Body><q0:sayHello><arg0>lisi</arg0></q0:sayHello></soapenv:Body></soapenv:Envelope>";


;
//获得输出流
OutputStream out = con.getOutputStream();
out.write(requestBody.getBytes());

out.close();

int code = con.getResponseCode();
if(code == 200){//服务端返回正常
InputStream is = con.getInputStream();
byte[] b = new byte[1024];
StringBuffer sb = new StringBuffer();
int len = 0;
while((len = is.read(b)) != -1){
String str = new String(b,0,len,"UTF-8");
sb.append(str);
}
System.out.println(sb.toString());
is.close();
}
con.disconnect();


}


}

3.但必须解析xml
