记一次Exception in thread "main" javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure报错

项目中需要用java调用第三方的https的接口，调试了好多次总是报javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure错误，皇天不负苦心人最后终于调试成功，废话不多说直接上代码（我代码放的比较全，也方便以后自己查看如何使用）；

public static String signature(String comeStr) throws Exception {
	SSLContext sc = createIgnoreVerifySSL();//调用
	String serverURL = "https://xxx";
	StringBuffer sbf = new StringBuffer();
	String strRead = null;
	URL url = new URL(serverURL);
	HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
	connection.setSSLSocketFactory(sc.getSocketFactory());
	connection.setRequestMethod("POST");// 请求post方式
	connection.setDoInput(true);
	connection.setDoOutput(true);
	// header内的的参数在这里set connection.setRequestProperty("健, "值");
	connection.setRequestProperty("Accept", "application/json");// 设置接收数据的格式
	connection.setRequestProperty("Content-Type", "application/json");
	connection.connect();
	OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
	// body参数在这里put到JSONObject中
	JSONObject outParm = new JSONObject(jsonBuild());//需要转换的json数据
	writer.write(outParm.toString());
	writer.flush();
	InputStream is = connection.getInputStream();
	BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
	while ((strRead = reader.readLine()) != null) {
		sbf.append(strRead);
		// sbf.append("\r\n");
	}
	String jsonStr = sbf.toString().replace("\"", "'");
	reader.close();
	connection.disconnect();
	JSONObject inParm = new JSONObject(jsonStr);
	String results = (String) inParm.get("pdf");
	return results;
}
