Java Maven项目的关键参数配置到pom文件的方法

需求：
比如在开发中数据库经常涉及到开发库和测试库，把数据库的信息放在pom里面可以利用命令实现库的切换，不需要改代码<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"> <modelVersion>4.0.0</modelVersion>

2. 映射到配置文件中,在config.properties中

jdbcUrl =${jdbcUrl}
user =${jdbc-user}
password =${jdbc-password}

然后在项目中就可以正常使用
在发布时，如果是开发库，打包的命令是mvn clean package -P dev
如果是正式库，打包的命令是mvn clean package -P pro
