配置Tomcat使用https协议

转自博主：https://www.cnblogs.com/wanghaoyuhappy/p/5267702.html

一. 创建tomcat证书

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文件

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

选择继续浏览此网站

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
