1.生成证书
(1)在jdk的安装目录\bin\keytool.exe下打开keytool.exe
在命令行中输入以下命令:
keytool -genkeypair -alias "tomcat" -keyalg "RSA" -keystore "E:\tomcat.keystore" -validity 36500
以上命令将生产一对非对称密钥和自我签名的证书E:\tomcat.keystore
注意：“名字与姓氏”应该是域名，输成了姓名，和真正运行的时候域名不符，会出问题
这里我输入的密码是123456, 域名是以tomcat为例, 省市以广东深圳为例
配置tomcat服务器
定位到tomcat服务器的安装目录, 找到conf下的server.xml文件
找到如下已经被注释的代码：
<!-- ????<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" ??
maxThreads="150" scheme="https" secure="true" ????clientAuth="false" sslProtocol="TLS" /> ??
-->
去掉注释，修改为：
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" ????????????????maxThreads="150" scheme="https" secure="true" ???????????????clientAuth="false" sslProtocol="TLS" ??????????keystoreFile="E:\tomcat.keystore" ????????keystorePass="123456" /> ?
在互联网上, http协议的默认端口是80, https的默认端口是443, 这里将端口改为了443
3.HTTP自动跳转配置
配置Tomcat，打开$CATALINA_HOME/conf/server.xml，修改如下
<Connector port="8080" protocol="HTTP/1.1" ??????????????connectionTimeout="20000" ??????????????redirectPort="8443" />
修改为
<Connector port="80" protocol="HTTP/1.1" ??????????????connectionTimeout="20000" ??????????????redirectPort="443" />
<!-- ??<Connector port="8009" enableLookups="false" protocol="AJP/1.3" redirectPort="8443" />-->
修改为：
<Connector port="8009" enableLookups="false" protocol="AJP/1.3" redirectPort="443" />
在tomcat\conf\web.xml中的</welcome-file-list>后面加上这样一段
???<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>
