tomcat的server.xml文件中添加配置

如下图

添加如下配置

<Connector port="443" SSLEnabled="true" secure="true" scheme="https">
  <SSLHostConfig>
    <Certificate certificateFile="conf/ssl2/cert.pem"
                 certificateKeyFile="conf/ssl2/privkey.pem"
                 certificateChainFile="conf/ssl2/chain.pem" />
  </SSLHostConfig>
