Tomcat配置8080强制跳转https端口变成8443或

Tomcat配置强制https端口变成8443

跳转端口：
http默认端口 8080
https默认端口 8443

或者

http默认端口 80
https默认端口 443
这里只讲tomcat配置，至于证书生成请参考其他文档；
修改tomcat配置文件 vim /etc/tomcat/server.xml 启用ssl

service.xml
    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Connector port="8443" protocol="HTTP/1.1"
                SSLEnabled="true"
                maxThreads="150" 
                scheme="https" 
                secure="true"
                keystoreFile="/usr/ca/server/server.keystore.jks"
                keystorePass="yzd2019"
                clientAuth="false" 
                sslProtocol="TLS" 

强制跳转：
访问http的8080或者80自动跳转
修改 web.xml

在welcome-file-list标签后加入
<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> 

注意： 如果是YUM安装的tomcat无法使用1024以下的端口固无法使用80与443 ；
若修改监听端口为80休要修改tomcat运行用户为root；安全起见官方不建议这么干；
修改下面的tomcat用户为root
vim /usr/lib/systemd/system/tomcat.service

# Systemd unit file for default tomcat
#

# DO NOTHING, use tomcat@.service instead.
