spring mvc 發送http post請求返回的中文數據亂碼

發送http post請求返回的數據中文亂碼，在網上搜了一下，找到一個相關的資源，結果發現用不了，最後自己試着改了一下，終於解決了這個亂碼的問題。

public static String post(String url, String charset, Map params) throws IOException {
		HttpURLConnection conn = null;
		OutputStreamWriter out = null;
		InputStream inputStream = null;
		InputStreamReader inputStreamReader = null;
		BufferedReader reader = null;
		StringBuffer result = new StringBuffer();
		try {
			conn = (HttpURLConnection) new URL(url).openConnection();
			conn.setDoOutput(true);
			conn.setDoInput(true);
			conn.setRequestMethod("POST");
			conn.setRequestProperty("accept", "*/*");
			conn.setRequestProperty("connection", "Keep-Alive");
			conn.setRequestProperty("Accept-Charset", charset);
			conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

			out = new OutputStreamWriter(conn.getOutputStream(), charset);
			out.write(buildQuery(params, charset));
			out.flush();
			inputStream = conn.getInputStream();
			inputStreamReader = new InputStreamReader(inputStream);
			reader = new BufferedReader(inputStreamReader);
			String tempLine = null;
			while ((tempLine = reader.readLine()) != null)
				result.append(tempLine);
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			if (out != null) {
				out.close();
			}
			if (reader != null) {
				reader.close();
			}
			if (inputStreamReader != null) {
				inputStreamReader.close();
			}
			if (inputStream != null) {
				inputStream.close();
			}
		}
		return result.toString();
	}

解決方法：

			inputStreamReader = new InputStreamReader(inputStream,"UTF-8");
