模拟请求webservice并获取返回报文

     有时需要模拟请求webservice服务，并处理返回的报文，根据报文的信息进行业务处理。

     样例代码如下： 

import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;

/**
 * Simulating request webservice
 * 模拟请求WEBSERVICE样例
 *
 */
public class SimRequestWS {

	/**
	 * 模拟请求WEBSERVICE方法
	 * @param url	请求的Webservice地址
	 * @param request	请求的报文，XML格式的字符串
	 * @return
	 */
	public static Map<String,String> doRequestWS(URL url, String request) {
		HttpURLConnection connection = null;
		String rspMsg = "";
		String rspCode = "ERROR";
		try {
			byte[] requestBuf = (byte[]) null;
			requestBuf = request.getBytes("gbk");

			connection = (HttpURLConnection) url.openConnection();
			connection.setDoOutput(true);
			connection.setDoInput(true);
			connection.setRequestMethod("POST");
			connection.setUseCaches(false);
			connection.setRequestProperty("Content-Type", "text/plain");
			connection.connect();

			DataOutputStream out = new DataOutputStream(
					connection.getOutputStream());
			out.write(requestBuf);
			out.flush();
			out.close();

			if (connection.getResponseCode() != 200) {
				System.out.println("ERROR: " + connection.getResponseMessage());
			}

			InputStream in = connection.getInputStream();
			ByteArrayOutputStream bufOut = new ByteArrayOutputStream();
			byte[] readBuf = new byte[100];
			while (true) {
				int ret = in.read(readBuf);
				if (ret < 0)
					break;
				bufOut.write(readBuf, 0, ret);
			}
			byte[] rspBuf = bufOut.toByteArray();

			rspMsg = new String(rspBuf, "gbk");
			rspCode = connection.getResponseMessage();
		} catch (Exception e) {
			e.printStackTrace();
		}

		connection = null;
		Map<String,String> map = new HashMap<String,String>();
		map.put("rspCode", rspCode);
		map.put("rspMsg", rspMsg);
		return map;
	}

	public static void main(String[] args) throws Exception,
			UnsupportedEncodingException {
		URL url = new URL("http://172.168.27.154:8081/cxfdemo?wsdl");

		Map<String,String> map =SimRequestWS.doRequestWS(
						url,
						"<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ws=\"http://ws.com/\">"
								+ "<soapenv:Header/>"
								+ "<soapenv:Body>"
								+ "<catt:hello>"
								+ "<arg0>李四</arg0>"
								+ "</catt:hello>"
								+ "</soapenv:Body>"
								+ "</soapenv:Envelope>");
		System.out.println(map);
	}
}

 模拟请求一个Webservice服务，返回信息如下：

{rspCode=OK, rspMsg=<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:helloResponse xmlns:ns2="http://catt.com/"><return>hello 李四</return></ns2:helloResponse></soap:Body></soap:Envelope>}
