Springboot Maven yaml 自動多環境打包工具

    在很多情況下,我們需要爲開發環境,集成測試環境,生產環境打包.它們的配置文件有細微的差異,最好是一次能夠生產所有環境的war包.比較常見的是設置application.properties中的spring.profiles.active環境變量
    但是yml的精簡特性很值得稱道,用過之後就不能忍受property 文件的臃腫了.試着google基於yml的多環境打包,並沒有一個很直觀的例子.雖然實現很簡單,還是要提供一個例子的,拿來就用,不用思考.

    實現的核心的Maven 插件maven resources plugin的拷貝文件和過濾文件的功能. 思路是把開發環境(dev),集成測試環境(sit),環境打包(prd)的配置文件分別放在src/main/resources 目錄下, 通過maven resources plugin把配置文件從src/main/resources/${profiles.active}拷貝到src/main/resources/ 然後打包
例如:
mvn clean
mvn package -P dev

每個profile都有自己的配置文件目錄,這些目錄的文件在打包的時候會被拷貝到resources目錄下:

使用此種方法打包生成的war包直接放到tomcat啓動就可以,不需要特別的設置.
