名词解释

        KeyStore

         密钥库是存储了密钥、证书链及受信任证书的数据库。

JAVA JDK 实现  生成keystore

          Windows JDK bin 下开启terminal

          keytool -genkeypair -alias "tomcat" -keyalg "RSA" -keystore "tomcat.keystore"

 建议使用通用的PKCS12

 Tomcat9 实现https 访问

    此处端口为443

如果不删除<SSLHostConfig>直接追加，启动会报错：conf/server.xml: Error at (92, 25) : Multiple SSLHostConfig elements were provided for the host name [_default_]. Host names must be unique.

 Tomcat9 强制http 跳转https

   此处端口为8443

     web.xml 添加如下的蓝色内容

 这次改成了8443

重启tomcat

https://localhost:8443/   正常访问

http://localhost:8080/   跳转到 https://localhost:8443/ 正常访问
