Springboot Maven yaml 自动多环境打包工具

在很多情况下,我们需要为开发环境,集成测试环境,生产环境打包.它们的配置文件有细微的差异,最好是一次能够生产所有环境的war包.比较常见的是设置application.properties中的spring.profiles.active环境变量
但是yml的精简特性很值得称道,用过之后就不能忍受property 文件的臃肿了.试着google基于yml的多环境打包,并没有一个很直观的例子.虽然实现很简单,还是要提供一个例子的,拿来就用,不用思考.

实现的核心的Maven 插件maven resources plugin的拷贝文件和过滤文件的功能. 思路是把开发环境(dev),集成测试环境(sit),环境打包(prd)的配置文件分别放在src/main/resources 目录下, 通过maven resources plugin把配置文件从src/main/resources/${profiles.active}拷贝到src/main/resources/ 然后打包
例如:
mvn clean
mvn package -P dev

pom.xml的profile配置和resources插件部分:

每个profile都有自己的配置文件目录,这些目录的文件在打包的时候会被拷贝到resources目录下:

使用此种方法打包生成的war包直接放到tomcat启动就可以,不需要特别的设置.
