# Gradle multiple subprojects & modules(用Springboot為專案)

---

[TOC]

---

## 使用的技術&工具

- Springboot 2.7.X
- Gradle 7.X

---

## 請先下載的Springboot

先到[https://start.spring.io/](https://) ，下載需要的專案
紅色部分是這一次範例的設定(Packaging到專案裡面會調整)

│   ├── settings.gradle

application的settings.gradle內容為

rootProject.name = 'application'

application的build.gradle內容為

## Module

Module專案目錄，專案名稱為library

├── TestModule

## 最後專案整合

TestModule的settings.gradle改為

rootProject.name = 'TestModule'
include 'library', 'application'

application的build.gradle改為

plugins {
	id 'java'
	id 'war'
}

dependencies {
	implementation project(':library')
}
