我试图建立一个ssl连接。我有一个服务器，我有一个客户端。我让它们都在同一台机器上运行。我正在尝试在客户端和服务器之间建立SSL连接。我使用以下keytool命令为服务器和客户端生成了证书。
对于客户
keytool -keystore clientstore -genkey -alias client -validity 3650
然后我将客户端的根证书导出到cer文件callled client.cer
对于服务器 keytool -keystore serverstore -genkey -alias server -validity 3650然后我将服务器的根证书导出到cer文件callled server.cer
我现在使用以下命令将客户端证书“client.cer”导入serverstore密钥库
keytool -import -keystore serverstore -file client.cer -alias client
并使用以下命令
将服务器证书“server.cer”导入clientstore密钥库keytool -import -keystore clientstore -file server.cer -alias server
执行此操作后，我将server.cer和client.cer都导入到cacerts Keystore中。但是，当我尝试建立一个ssl连接时，我在服务器javax.net.ssl.SSLHandshakeException上出现此错误：null cert chain和客户端javax.net.ssl.SSLHandshakeException上的此错误：收到致命警报：bad_certificate。

可能导致此错误的原因是什么？可能是因为我在同一台计算机上同时运行服务器和客户端？...现在已经有一段时间了。我需要帮助
答案 0 :(得分：0)
请尝试包含此代码段，以便信任所有证书。
public static void trustSelfSignedSSL() {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string)
throws CertificateException {}
public void checkServerTrusted(X509Certificate[] xcs, String string)
throws CertificateException {}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[] { tm }, null);
SSLContext.setDefault(ctx);
} catch (Exception ex) {
// LOGGER.error("Exception : ", ex.getStackTrace());
System.out.println(ex.getStackTrace());
}
