在https post请求时发生这个错误
原因：使用的jdk1.7，只支持TLSv1，不支持TLSv1.1 和 TLSv1.2
使用工具类处理：
方法一：
public static String postTLS(String requestUrl, Map<String, String> params) {
HttpPost httpPost = new HttpPost(requestUrl);
CloseableHttpClient createSSLClientDefault = createSSLClientDefault("");
CloseableHttpResponse httpResponse = null;
try {
logger.info("request httpspost：" + requestUrl);
List<NameValuePair> list = new ArrayList();
for (String key: params.keySet()) {
list.add(new BasicNameValuePair(key, params.get(key)));
}
StringEntity stringEntity = new UrlEncodedFormEntity(list, "UTF-8");
stringEntity.setContentType("application/x-www-form-urlencoded");
httpPost.setEntity(stringEntity);
logger.info("execute post...");
httpResponse = createSSLClientDefault.execute(httpPost);
StatusLine statusLine = httpResponse.getStatusLine();
int state = statusLine.getStatusCode();
logger.info("response status: " + state);
if (state == HttpStatus.SC_OK) {
HttpEntity httpEntity = httpResponse.getEntity();
String result = EntityUtils.toString(httpEntity,"UTF-8");
logger.info("httpspost result：" + result);
return result;
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (httpResponse != null) {
try {
httpResponse.close();
} catch (IOException e) {
e.printStackTrace();
}
}
try {
createSSLClientDefault.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
private static CloseableHttpClient createSSLClientDefault(String tls) {
try {
X509TrustManager trustManager = new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
TrustManager[] tm = new TrustManager[]{trustManager};
sslContext.init(null, tm, new java.security.SecureRandom());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
return HttpClients.custom().setSSLSocketFactory(sslsf).build();
} catch (KeyManagementException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return HttpClients.createDefault();
}方法二：使用Bouncy Castle
