用户端与Nginx通讯使用https，Nginx与tomcat通讯可以只使用http，简化证书配置。
Nginx端配置nginx.conf

}其中最为关键的就是 ssl_certificate 和 ssl_certificate_key 这两项配置，其他的按正常配置。不过多了一个 proxy_set_header X-Forwarded-Proto https; 配置。
tomcat端配置server.xml
<?xml version='1.0' encoding='utf-8'?> <Server port="8005" shutdown="SHUTDOWN"> <Service name="Catalina"> <Connector port="8090" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="443" proxyPort="443"/> <Engine name="Catalina" defaultHost="localhost"> <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"> <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="x-forwarded-for" remoteIpProxiesHeader="x-forwarded-by" protocolHeader="x-forwarded-proto" /> <Context path="" docBase="/oschina/webapp" reloadable="false"/> </Host> </Engine> </Service> </Server>
必须有 proxyPort="443"，这是整篇文章的关键，当然 redirectPort 也必须是 443。同时 <Value> 节点的配置也非常重要，否则你在 Tomcat 中的应用在读取 getScheme() 方法以及在 web.xml 中配置的一些安全策略会不起作用。
