调用微信公众https接口出现KeyException异常

各位大牛好：

      我在用程序调用微信公众平台https的时候，本地测试调用方法是可以获取到信息的，但是将程序放在服务器上，就出现以下问题：

我已经尝试过网上很多忽略ssl的方法来测试，都没有成功，各位大牛应该怎么解决啊，谢谢啦！

public static String get(String url) throws IOException {
StringBuffer buffer = new StringBuffer();
try {
TrustManager[] tm = { new MyX509TrustManager() };
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, tm, new java.security.SecureRandom());
SSLSocketFactory ssf = sslContext.getSocketFactory();
URL _url = new URL(url);
HttpsURLConnection httpUrlConn = (HttpsURLConnection) _url
.openConnection();
httpUrlConn.setSSLSocketFactory(ssf);
httpUrlConn.setDoOutput(true);
httpUrlConn.setDoInput(true);
httpUrlConn.setUseCaches(false);
httpUrlConn.setRequestMethod("GET");
InputStream inputStream = httpUrlConn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(
inputStream, "utf-8");
BufferedReader bufferedReader = new BufferedReader(
inputStreamReader);
String content = null;
while ((content = bufferedReader.readLine()) != null) {
buffer.append(content);
}
bufferedReader.close();
inputStreamReader.close();
inputStream.close();
inputStream = null;
httpUrlConn.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
return buffer.toString();
}

public static CloseableHttpClient createSSLClientDefault() {
try {
SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(
null, new TrustStrategy() {
// 信任所有
public boolean isTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
return true;
}
}).build();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
sslContext);
return HttpClients.custom().setSSLSocketFactory(sslsf).build();
} catch (KeyManagementException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyStoreException e) {
e.printStackTrace();
}
return HttpClients.createDefault();
}


class AnyTrustStrategy implements TrustStrategy {


@Override
public boolean isTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
return true;
}


}

以上方法都测试过，没有效果。

服务器的配置是： centos + tomcat + mysql + openJDK
