这里使用JDK自带的keytool工具来生成证书：
1. 在jdk的安装目录\bin\keytool.exe下打开keytool.exe
2. 在命令行中输入以下命令:
keytool -genkeypair -alias "tomcat" -keyalg "RSA" -keystore "g:\tomcat.keystore" 
以上命令将生产一对非对称密钥和自我签名的证书g:\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
二. 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
找到如下已经被注释的代码：
1 <!-- 2 <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" 3 maxThreads="150" scheme="https" secure="true" 4 clientAuth="false" sslProtocol="TLS" /> 5 -->
去掉注释，修改为：
1 <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" 2 maxThreads="150" scheme="https" secure="true" 3 clientAuth="false" sslProtocol="TLS" 4 keystoreFile="g:\tomcat.keystore" 5 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
三. 启动tomcat服务器
在IE浏览器中输入: https://localhost

搞定了!!!!
遇到的问题:
我在配置的过程中问题，当我修改了server.xml的配置后，启动tomcat报错

网上找了下，
可以将protocol="HTTP/1.1"替换为protocol="org.apache.coyote.http11.Http11Protocol"，问题可以得以解决
