前两天没事的时候去阿里云瞎逛的时候发现可以免费申请SSL证书，就去申请了几个玩玩，但是申请完成后在Tomcat配置的时候遇到了几个坑，下面就教大家配置一下
下面是我的域名：
注意红色字体部分，红色字体部分是需要根据你自己的需求修改的
先去阿里云申请SSL证书
申请完成后提交到阿里审核，审核通过了的话就可以部署和下载相关的证书，然后配置到自己服务器上面
注意：需要下载两个压缩文件，特别是“其他？”里面有一个pem文件，我之前部署的时候没注意，启动一直报错，后面网上找了很多看他们都有，我就又重新去下载，然后找到了，记住要下载“其他”，如下图所示：
下面是tomcat/conf/server.xml文件
