使用Maven Profile构建不同环境配置

布满荆棘的人生 2022-03-17 15:43 284阅读 0赞

一个项目可以部署在不同的环境当中，maven 的 profile 针对不同的环境指定各自的环境。在 pom.xml 的 profile 中，可以根据不同的环境定制环境配置，最多的配置莫过于数据库的配置，下面以数据库配置为实例，演示配置过程：

新建一个Maven的Web 工程实验

然后建立如下文件结构

然后在pom文件添加如下内容：

<project xmlns="http://maven.apache.org/POM/4.0.0"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

四个properties文件的内容如下【三个不同环境的文件和一个真正填充环境配置的文件，即在在通过Spring扫描的时候配置应该是用properties/config.properties文件】：

dev:

jdbc.driverClassName=com.mysql.jdbc.Driver 
    jdbc.url=jdbc:mysql:///dev 
    jdbc.username=dev 
    jdbc.password=xyz

uat:

jdbc.driverClassName=com.mysql.jdbc.Driver 
    jdbc.url=jdbc:mysql:///uat
    jdbc.username=uat
    jdbc.password=xyz

prd:

jdbc.driverClassName=com.mysql.jdbc.Driver 
    jdbc.url=jdbc:mysql:///prd
    jdbc.username=prd
    jdbc.password=xyz

真正填充上面的配置文件：properties/config.properties

jdbc.driverClassName=com.mysql.jdbc.Driver 
    jdbc.url=${jdbc.url}
    jdbc.username=${jdbc.username}
    jdbc.password=${jdbc.password}
