javax.net.ssl.SSLHandshakeException: sun.security.validator 问题解决,与环境有关

用httpclient访问https 资源时,会出现异常,与环境也有关系，有些机器请求正常.

 

 错误详情：

解决方法：

增加一个自己的https协议类 MySSLSocketFactory.java

请求类：

public class HttpsRequest {

    /**
     * 
     * @param url

     */
    public static String post(String url) {
        //增加下面两行代码
        Protocol myhttps = new Protocol("https", new MySSLSocketFactory(), 443);
        Protocol.registerProtocol("https", myhttps);
        
        HttpClient client = new HttpClient();

            return result;
        } catch (HttpException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            post.releaseConnection();
        }
        return null;
    }
}

 

 

 

测试：

 

public static void main(String[] args) {
        System.out.println(HttpsRequest.post("https://www.alipay.com"));//支付宝做测试
    }
