William Yu published on 2021-08-28 included in Spring Boot Vue

Intro

To develop a single-page application, Spring Boot and Vue can be a good choice. When you finished the development stage, it is time to deploy the app online.

Traditionally, you may need to write scripts to start your java service, and you need to do a lot of configuration for the Nginx server.
