tomcat开启https协议

1.在tomcat的conf/server.xml 中配置

                   
    <Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS"
               keystoreFile="D:keystorezhihu.org.cnTomcatzhihu.org.cn.jks"

               keystorePass="123456"
/>

2. 将 redirectPort 的端口号都指向443

    <Connector connectionTimeout="20000" port="9002" protocol="HTTP/1.1" redirectPort="443"/>
    
 <Connector port="8009" protocol="AJP/1.3" redirectPort="443"/>

3.在conf/web.xml里最下面配置

<security-constraint><web-resource-collection >
    <web-resource-name >SSL</web-resource-name>
    <url-pattern>/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
    <transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint></security-constraint>

4. 重启tomcat，然后再打浏览器里打开

zhihu.org.cn  会自动跳转到 https://zhihu.org.cn   (会显示404)

打开 默认应用 https://zhihu.org.cn/examples/   可看到正常效果
