使用maven profile指定配置文件打包适用多环境

开发过程, 我们习惯把数据源配置, 项目常量, 日志配置等基础数据配置写到一个个单独的的文件中. 如jdbc.properties等各种.格式的文件.

 

如何不频繁修改配置文件, 随时打包不同基础数据配置信息的项目.

1.新建maven项目,   在pom.xml中添加 profile节点信息如下:

 

[html] view plain copy

1. <profiles>  
2.         <profile>  
3.               
4.             <id>devid>  
5.             <properties>  
6.                 <environment>developmentenvironment>  
7.             properties>  
8.             <activation>  
9.                 <activeByDefault>trueactiveByDefault>  
10.             activation>  
11.         profile>  
12.         <profile>  
13.               
14.             <id>testid>  
15.             <properties>  
16.                 <environment>testenvironment>  
17.             properties>  
18.         profile>  
19.         <profile>  
20.               
21.             <id>previd>  
22.             <properties>  
23.                 <environment>previewenvironment>  
24.             properties>  
25.         profile>  
26.         <profile>  
27.               
28.             <id>prodid>  
29.             <properties>  
30.                 <environment>productionenvironment>  
31.             properties>  
32.         profile>  
33. profiles>  

 

 

 

 

 2. 在项目中添加各环境需要的数据源配置文件,分不同目录存放, 分别是开发,测试, 预演,生产  环境. 如下图左边部分所示.  

 

3. pom.xml中配置resource节点信息.

[html] view plain copy

1. <build>             
2.     <resources>  
3.         <resource>  
4.             <directory>src/main/resourcesdirectory>  
5.             <excludes>  
6.                 <exclude>environment/development/*exclude>    
7.                 <exclude>environment/test/*exclude>    
8.                 <exclude>environment/preview/*exclude>    
9.                                 <exclude>environment/production/**exclude>  
10.             excludes>  
11.         resource>  
12.         <resource>  
13.             <directory>src/main/resources/environment/${environment}directory>  
14.             <targetPath>environment/${environment}targetPath>  
15.         resource>  
16.     resources>  
17. build>  

 

resource节点信息解释: 

 

[html] view plain copy

1. <directory>src/main/resourcesdirectory>   
2. <exclude>environment/development/**exclude>   
3. <exclude>environment/test/**exclude>   
4. <exclude>environment/preview/**exclude>   
5. <exclude>environment/production/**exclude>  
6.   
7.   

 

[html] view plain copy

1. <directory>src/main/resources/environment/${environment}directory>   
2. <targetPath>environment/${environment}targetPath>  

4.  项目打包.   打包命令mvn package -Pdev来指定激活id为 dev 的profile节点, 这样, 开发环境配置文件就会被打包.
开发: mvn package -Pdev (因为配置了默认激活dev部分, 所以也可以使用mvn package, 这与 mvn package -Pdev 效果相同)
测试: mvn package -Ptest
预演:mvn package -Pprev
生产:mvn package -Pprod
