在Java客户端中接受服务器的自签名ssl证书

这里基本上有两个选择：将自签名证书添加到JVM信任库中，或将客户端配置为

选项1
从浏览器导出证书，并将其导入到JVM信任库中（以建立信任链）：

<JAVA_HOME>binkeytool -import -v -trustcacerts-alias server-alias -file server.cer-keystore cacerts.jks -keypass changeit-storepass changeit 

选项2
禁用证书验证：

// Create a trust manager that does not validate certificate chainsTrustManager[] trustAllCerts = new TrustManager[] {     new X509TrustManager() {  public java.security.cert.X509Certificate[] getAcceptedIssuers() {  return new X509Certificate[0];        }         public void checkClientTrusted(  java.security.cert.X509Certificate[] certs, String authType) { }         public void checkServerTrusted(  java.security.cert.X509Certificate[] certs, String authType) {        }    } }; // Install the all-trusting trust managertry {    SSLContext sc = SSLContext.getInstance("SSL");     sc.init(null, trustAllCerts, new java.security.SecureRandom());     HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());} catch (GeneralSecurityException e) {} // Now you can access an https URL without having the certificate in the truststoretry {     URL url = new URL("https://hostname/index.html"); } catch (MalformedURLException e) {} 

请注意，我完全不建议使用选项2。禁用信任管理器会破坏SSL的某些部分，并使您容易受到中间攻击的攻击。首选选项1，或者甚至更好，让服务器使用由知名CA签名的“真实”证书。
