背景提要

使用SpringInitializer建立新專案後，使用原專案中的程式碼結構對專案進行初始化，其中springProfile包含關係如下：

application.yml
	include: repository,service,web
	active: dev
application-dev.yml
	include: repository-dev,service-dev,web-dev
application-release.yml
	include: repository-release,service-release,web-release
 

發現啟動時報錯說找不到資料庫配置

Consider the following:
	If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
	If you have database settings to be loaded from a particular profile you may need to activate it (the profiles dev,repository,service,web are currently active).

經查發現springBoot2.4對配置檔案的載入做了更新

解決方法

強制spring使用原載入方式載入配置檔案

需要在application.yml中增加如下配置

spring:
	config:
		use-legacy-processing: true

WIKI中解釋如下：

使用profile group管理配置檔案

spring:
  application:
    name: sc_server_user
  profiles:
    group:
      "dev": "repository-dev,service-dev,web-dev"
      "release"
 
: "repository-release,web-release,service-release"
    active: @[email protected]
    include: "repository,service,web"

詳見上述官方WIKI!
