tomcat8
conf/server.xml
中原屬於80端口的http修改爲(tomcat默認是8080端口)

    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="443" />

之後在conf/web.xml的最下面</web-app>前加上

	<login-config>
        <!-- Authorization setting for SSL -->
        <auth-method>CLIENT-CERT</auth-method>
        <realm-name>Client Cert Users-only Area</realm-name>
    </login-config>
    <security-constraint>
        <!-- Authorization setting for SSL -->
        <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>

之後重啓tomcat即可
