javax.net.ssl.SSLHandshakeException:空证书链java错误

我正在尝试建立ssl连接。我有一个服务器和一个客户端。我让它们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。我已经使用下面的keytool命令为服务器和客户端生成了证书

为客户

keytool-keystoreclientstore-genkey-alias-client-validity 3650

然后我将客户端的根证书导出到一个名为client.cer的cer文件中

对于服务器 keytool-keystoreserverstore-genkey-alias server-validity 3650然后我将服务器的根证书导出到一个名为server.cer的cer文件中

现在，我使用以下命令将客户端证书“client.cer”导入serverstore密钥库

keytool-import-keystoreserverstore-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

完成此操作后，我将server.cer和client.cer都导入到cacerts密钥库中。但是，当我尝试建立ssl连接时，在服务器javax.net.ssl.SSLHandshakeException:null证书链上出现此错误，在客户端javax.net.ssl.SSLHandshakeException:Received fatal alert:bad_certificate上出现此错误

是什么导致了这个错误？可能是因为我在同一台机器上同时运行服务器和客户端吗？…已经在这上面运行了很长时间了。我需要帮助

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;
            }
        };

在哪里包含此代码段？在服务器上还是在客户机上？将其包含在客户机中。在何处包含此代码段？在服务器上还是在客户机上？将其包括在客户机中。
