第一步:阿里云申请免费的SSL证书

申请免费证书比较简单,坑比较少,故不多说,网上很多相关资料
免费证书支持多个服务器,这里演示的是Tomcat服务器

证书需要绑定你购买的域名

阿里云ssl证书控制中心

一定要是签发状态

第二步:配置Tomcat

从阿里云SSL控制台下载SSL证书并解压

把解压的文件放入远程服务器Tomcat目录下的cert目录(新建cert目录)

进入Tomcat conf目录配置server.xml文件

    </Engine>
  </Service>
</Server>

第三步:去掉8443端口

上面配置文件已经把8443端口去掉了。如果想改回来,只要把截图中的443更换为8443端口,或者其它你想要的端口号。

第四步:http自动重定向到https

tomcat conf目录下的web.xml末尾加上如下配置:

<security-constraint>

    <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>

前提是Http和Https都可正常访问的情况下。
