如何为 Spring Boot 应用程序配置嵌入式 Tomcat 虚拟主机？

Question

i have a multiple domains on my centos vps (domains running on apache http server via virtual host configurations). and also same vps, i want to add my new domain but that domain will route my spring boot application (application is a jar file also inside embedded tomcat ). i couldn't find any configuration for embedded tomcat specific domains and ports.

standalone Tomcat i can make configuration via server.xml file like this image

also this short tutorial shows configuration for stadalone tomcat Tomcat Virtual Host Configuration

But how can i do that configuration for embedded Tomcat ? Any suggestion ?

Answer 1

With Spring Boot embedded Tomcat, you are hosting only one application per servlet container. So I don't believe that Tomcat's concept of Virtual Hosts make sense at all.

If you have to host your app on shared Tomcat instance, just build WAR without embedded container.

Answer 2

It depends. 2 ways to deploy your project.jar as you want to :

First way : You can use the "apache web server" and his own "mod_proxy" in order to serve as many Spring webapps you want to, each on a specific port configured with "php-fpm" and with a proxy defined to route requests from/to your namebased VirtualHost configuration.

Nowadays, with Spring Boot 2.5 , all you have to do is to set the property server.port in your application.properties file, and use it accordingly with mod_proxy directives. If you are using profile, you can either set one port to dev or prod or test or whatever properties file you need.

Another way to proceed : you can use the apache web server "mod_jk" bridge module to configure multiple load-balancers for your Virtualhosts too.

Choose your path, young Jedi ;)
