Tomcat - 使用 SSL 连接器启动时出现空指针异常

Question

我想为我的 Tomcat 9.0 服务器添加 SSL 可能性。正如 Tomcat 的说明所说，我已经使用 keytool 生成了一个 key ，并将以下连接器添加到 server.xml 文件

<Connector
       protocol="org.apache.coyote.http11.Http11NioProtocol"
       port="8443" maxThreads="200"
       scheme="https" secure="true" SSLEnabled="true"
       keystoreFile="C:\Moje_programy\spring\apache-tomcat-9.0.0.M11\klucz" keystorePass="samplepassword"
       clientAuth="false" sslProtocol="TLS"/>

当我尝试启动服务器时出现以下错误(并且 ssl 端口不工作):

不知道是不是bug，还是我做的不对。

解决方案令人惊讶，但是在 key 生成期间，别名属性必须设置为“tomcat”

有我的例子:

c:\Program Files\Java\jdk1.8.0_112\bin>keytool -genkey -alias tomcat -keyalg RSA -keystore C:\Moje_programy\spring\apache-tomcat-9.0.0.M11\klucz
