使用Maven实现环境隔离

一、环境隔离的目的:

解决不同环境中配置存在的差异;

二、实际项目环境有以下几种:

本地开发环境:Local

开发环境:Dev

测试环境:Beta

线上环境:Prod

三、隔离环境之间配置的差异:

如Ftp配置、数据库配置等

四、Maven环境隔离解决的实际问题

1.避免人工修改的弊端,也就是说手动修改 系统配置时容易出现错误

2.根据不同环境进行 编译、打包、部署

五、Maven环境配置及原理

在 pom.xml中build节点增加如下代码:

<resources>
	<resource>
		<directory>
			src/main/resources.${deploy.type}				</directory>
		<excludes>
	        <exclude> *.jsp</exclude>
        </excludes>
     </resource>
     <resource>
     	<directory> src/main/resources</directory>
     </resource>
 </resources>
 
 *****************************************
 特别注意:<resources></resources>这一段要放在 <build></build>节点里面
 *********************************************

在pom.xml中增加profiles节点,指定环境,相当于SpringBoot中的spring.profile.active=dev 或prod

 *****************开发环境*******************
 <profiles>
 	<profile>
 		<id> dev </id>
 		<activation>
 		  <!--默认环境-->
 			<activeByDefault>true</activeByDefault>
 		</activation>
        <properties>
        	<deploy.type> dev </deploy.type>
        </properties>
    </profile>
        *******************测试环境******************

    <profile>
 		<id> dev </id>
        <properties>
        	<deploy.type> beta </deploy.type>
        </properties>
    </profile>  
    *******************生产环境******************
    <profile>
 		<id> dev </id>
        <properties>
        	<deploy.type> prod </deploy.type>
        </properties>
    </profile>    
 </profiles>
 

****************Maven环境隔离打包命令***************************
mvn clean package -Dmaven.test.skip=true  -Pdev或者是-Pprod  或者是 -Pbeta

六、Maven环境隔离目录初始化

新建对应的文件夹,并且把要隔离的文件分开,公共的留下

公共的为 resources

创建不同环境下的 不同文件夹

七、Maven环境隔离IDEA中设置默认环境

八、Maven环境隔离 编译、打包命令

-P${环境标识} Dev 、Prod、Beta

命令如下:

mvn clean package -Dmaven.test.skip=true -Pprod

执行打包命令有很多种方式:

方式1:在 idea控制台 Terminal 执行,如图所示

方式2:在Windows命令窗口执行,如下图,记得一定要进入到项目所在 目录下

九、在 Idea中发布项目

在idea中发布项目时,需要勾选下面的环境,然后 导入依赖,import Changes ,然后运行Tomcat,直接就发布过去了,此时到target/classes下面找,就可以看到了

十、完整 Pom文件

<?xml version="1.0" encoding="UTF-8"?>
