tomcat 配置http跳转https

web.xml增加配置

<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>

server.xml配置https8443端口

    <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
   keystoreFile="conf/keystore.jks"
   keystorePass="123456"
   clientAuth="false" sslProtocol="TLS" URIEncoding="UTF-8" />

然后redirectPort都指向8443

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8" />

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

在使用IE11,tomcat6.0.20时，ie访问https端口会出现页面无法访问问题。可能是版本问题，换成tomcat7.0.94了就可以了。如有同类问题请参考。
