springboot项目利用maven进行多环境打包

### 项目开发环境 ###

springboot2.0

jdk1.8

### 如何利用maven对springboot项目进行多环境打包呢？ ###

springboot运行的时候默认是加载application.properties的，如果还是按照传统springmvc的maven多环境打包方式直接将配置命名为application-dev.properties,application-sit.properties等等是无法运行成功的。

那么该怎么办呢？首先找到突破口——application.properties，在项目中还是保留application.properties，根据springboot的多环境启动配置，可以在application.properties中配置启动哪个环境的配置，**具体项目结构如下**：

红圈圈中的即为需要定义的properties

首先看下application.properties这个配置文件的内容，本地启动时通过spring.profiles.active=dev直接来指定需要的环境的配置文件，但在通过maven打包的时候启用这个配置spring.profiles.active=@profiles.active@。spring.profiles.active就是springboot提供的在多环境配置的时候用来指定要加载对应的配置文件的。

**application.properties文件如下：**

#指定运行环境dev(开发环境使用)， sit（测试环境使用）, prod（生产环境使用）. 
    #maven打包的时候改为spring.profiles.active=@profiles.active@，@profiles.active@来自maven打包时指定的打包环境, 对应pom文件中的标签profiles.active
    #spring.profiles.active=dev
    spring.profiles.active=@profiles.active@

另外说明下，在Spring Boot中多环境配置文件名需要满足`application-{profile}.properties`的格式，其中`{profile}`对应你的环境标识，比如：

*  `application-dev.properties`：开发环境
 *  `application-test.properties`：测试环境
 *  `application-prod.properties`：生产环境

**pom文件配置**

**如果通过eclipse进行打包的话，只需要改两个地方，看下面的截图：**

**上图中的profiles的值sit对应pom文件中多文件配置profile下的子标签id，看下图**

### 总结 ###

至此这个maven的打包配置完成，其实springboot多环境打包的难点就是如何保留application.properties
