Java 通过HttpURLConnection Post方式提交xml，并从服务端返回数据

import java.io.InputStream;

public class PostXml {
public static void main(String args[]) {

// 创建url资源
URL url = new URL("http://119.29.85.118//finance.php");
// 建立http连接
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
// 设置允许输出
conn.setDoOutput(true);

conn.setDoInput(true);

// 设置不用缓存
conn.setUseCaches(false);
// 设置传递方式
conn.setRequestMethod("POST");
// 设置维持长连接
conn.setRequestProperty("Connection", "Keep-Alive");
// 设置文件字符集:
conn.setRequestProperty("Charset", "UTF-8");
//转换为字节数组
byte[] data = xml.getBytes();
// 设置文件长度
conn.setRequestProperty("Content-Length", String.valueOf(data.length));
// 设置文件类型:
conn.setRequestProperty("contentType", "text/xml");
// 开始连接请求
conn.connect();
OutputStream  out = conn.getOutputStream();
// 写入请求的字符串
out.write(data);
out.flush();
out.close();

System.out.println(conn.getResponseCode());

// 请求返回的状态
if (conn.getResponseCode() == 200) {
System.out.println("连接成功");
// 请求返回的数据
InputStream in = conn.getInputStream();
