android 访问https 证书问题 报错javax.net.ssl.SSLHandshakeException

服务器url 切换为https后所有接口调用报错javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

解决办法：

Android项目中使用 retrofit + rxjava +mvvp 架构

故在RetrofitConfig.java 的配置文件中  初始化

initOkhttp(){}

方法中加入以下代码

OkHttpClient.Builder builder = new OkHttpClient.Builder();int[] certificates = {R.raw.new_dd};String hosts[]= {"*.diandianwaimai.com"};//builder.sslSocketFactory(SslContextFactory.getSSLSocketFactory(DDApplication.getInstance().getContext(),   certificates));//builder.hostnameVerifier(SslContextFactory.getHostnameVerifier(hosts));try {   CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509");   KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());   keyStore.load(null);   String certificateAlias = Integer.toString(0);   keyStore.setCertificateEntry(certificateAlias, certificateFactory.         generateCertificate(DDApplication.getInstance().getContext().getResources().openRawResource(R.raw.new_dd)));   SSLContext sslContext = SSLContext.getInstance("TLS");   final TrustManagerFactory trustManagerFactory =         TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());   trustManagerFactory.init(keyStore);   sslContext.init         (               null,               trustManagerFactory.getTrustManagers(),               new SecureRandom()         );   builder.sslSocketFactory(sslContext.getSocketFactory());   builder.hostnameVerifier(new HostnameVerifier() {      @Override      public boolean verify(String s, SSLSession sslSession) {         return true;      }   });} catch (CertificateException e) {   e.printStackTrace();} catch (KeyStoreException e) {   e.printStackTrace();} catch (NoSuchAlgorithmException e) {   e.printStackTrace();} catch (IOException e) {   e.printStackTrace();} catch (KeyManagementException e) {   e.printStackTrace();} catch (Exception ex) {}

其中 new_dd 文件是在raw目录下

生成.cer文件的方式给出链接自己去看，我就不重复了
