如何将我的代码分成两个应用程序？

Question

I have a few java classes, holding my application's logic. Now I want to create two applications, one will be a SpringBoot web application and another one will be a desktop application. Both of them will use logic, that I already wrote. I see only one way to do it: compiling logic classes into a .jar file and then putting it as a library into two Idea projects. But if I update any of this code, I will have to recompile it into jar and then replace an old jar with a new one in both projects.

1. Is there another, more simple way two divide my code into two projects?
2. What should I do with Git/GitHub?

PS My project is in java, I use Intellij IDEA, GitHub.

Answer 1

Multi-module project

As commented , you need a multi-module project. The content for each module is compiled separately, producing separate JAR files.

IntelliJ supports multi-module projects.

I recommend using a common Java build management tool to assist. Apache Maven is one such tool that supports multiple modules .

The word “module” used here in this context should not be confused for the Java Platform Module System . You may or may not choose to use Java modules in your project modules' code.

Answer 2

I suggest rest web service interface to export the logic data..

SpringBoot web application can consume the rest services
and the other a desktop application can consume the rest services

ONE REST SERVICE LAYER

Desktop app,     SpringBoot web application

this way to don't duplicate your code and bugs twice.
