我一直在研究从动态Web应用程序中提取信息的程序,该程序运行正常,直到我将我的tomcat服务器设置为使用自签名(因此,不受信任)证书使用SSL.错误的堆栈跟踪是:

在Web浏览器中,当访问具有不受信任证书的HTTPS站点时,系统会向用户发出警告,并且如果他想继续,则要求例外; 我想为我的命令行应用程序实现类似的功能......我承认我是socket编程和网络的新手; 任何解决这个问题的建议都会很棒!
这是一些相关的代码:
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
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 manager
try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
}
// Now you can access an https URL without having the certificate in the truststore
try {
URL url = new URL("https://hostname/index.html");
} catch (MalformedURLException e) {
}
这将完全禁用SSL检查 - 只是不要从这些代码中学习异常处理!
要做你想做的事,你必须在TrustManager中实现一个提示用户的检查.
从下面的代码这里是一个有用的解决方案.没有密钥库等.只需在初始化服务和端口(在SOAP中)之前调用方法SSLUtilities.trustAllHttpsCertificates().
