javax.net.ssl.SSLHandshakeException：null证书链空证书链

问题描述：

我有一个服务器，我有一个客户端。我有他们两个在同一台机器上运行。我试图建立客户端和服务器之间的SSL连接。我使用以下keytool命令为服务器和客户端生成了证书。javax.net.ssl.SSLHandshakeException：null证书链空证书链

对于客户的keytool -keystore clientstore -genkey -alias客户-validity 3650

然后我在客户端的根证书导出到callled client.cer

服务器A CER文件的keytool -keystore serverstore -genkey -alias服务器-validity 3650 然后，我将服务器的根证书导出到cer文件，调用server.cer

我现在将客户端证书“client.cer”导入serverstore密钥存储库中， G指令

的keytool -import -keystore serverstore -file client.cer -alias客户

而且还导入服务器证书 “server.cer” 到clientstore密钥库使用以下命令

的keytool -import -keystore clientstore -file server.cer -alias服务器

完成此操作后，我将server.cer和client.cer都导入到cacerts密钥存储区。但是，当我尝试建立一个ssl连接时，我得到服务器上的此错误javax.net.ssl.SSLHandshakeException：null证书链和客户端javax.net.ssl.SSLHandshakeException上的此错误：收到致命警报：bad_certificate。

什么可能会造成这个错误？可以的因为我在同一台计算机上同时运行服务器和客户端？...已经在此上了很长时间了。我需要帮助

你发现什么问题了？我有类似的问题。 – WiteCastle

发表了答案 –

答

@WiteCastle是的，我相信我，我有一个真正不愉快的经历，找出问题所在。在我粘贴我的代码片段之前，首先解释客户端和服务器之间的SSL Communication.SSL连接。

客户说你好
服务器说你好。
服务器提供。验证证书。
客户端检查证书是否在其TrustStore中。
客户端证书的服务器请求。
客户端提供证书供服务器验证。
如果客户端证书通过验证通信现在可以发生。

所以javax.net.ssl.SSLHandshakeException：收到致命警报：当客户端证书上的服务器和javax.net.ssl.SSLHandshakeException验证失败情况发生空证书链错误bad_certificate发生在服务器无法找到证明客户在其信任库中提供的证书。所以我所做的就是
