https请求微信分账接口 使用证书双向认证，
在本地可以收到返回 在Linux服务器中发起请求之后报错
java.lang.IllegalArgumentException: no SSLSocketFactory specified
在本地跑是没问题的 一上服务器就挂了 ，证书认证也是加上了的，请求帮助 谢谢！
public static String sendXmlWithCertificate(String urlStr, String xmlInfo, String mchId) {
BufferedReader br = null;
try {
URL url = new URL(urlStr);

// 设置通用的请求属性
connection.setUseCaches(false);
connection.setDoOutput(true);
connection.setDoInput(true);
//设置报文格式
connection.setRequestProperty("Content-Type", "text/xml");
//证书双向验证
connection.setSSLSocketFactory(readCertificate(mchId));
// 得到请求的输出流对象
DataOutputStream out = new DataOutputStream(connection.getOutputStream());
out.write(xmlInfo.getBytes(StandardCharsets.UTF_8));
out.flush();
out.close();
// 建立实际的连接
connection.connect();
// 定义 BufferedReader输入流来读取URL的响应
