Maven打包配置文件

通常我们会有多个系统环境，对应有不同的配置文件，通常在maven中我们打包只有jar, pom, maven-plugins, war and ear. 为了可以同时打包不同环境的配置文件，我们选择maven-assembly-plugin，把指定路径下的各种环境配置打包成zip和tar.gz包。

文件夹结构如下：

// mave standard folders
src/main/java
....
//config folder and files for different env
conf/dev (properties and log4j xml files)
conf/local
conf/uat
conf/prod
//config assembly files for different env
src/main/assembly/config/dev.xml
src/main/assembly/config/local.xml
src/main/assembly/config/uat.xml
src/main/assembly/config/prod.xml

maven pom实现：

<properties>
<!-- -->
<assemble.directory>${basedir}/conf</assemble.directory>
</properties>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<id>package-config</id>
<!-- 绑定到package生命周期阶段上 -->
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptorSourceDirectory> <!--描述文件夹路径-->                                <descriptor>${basedir}/src/main/assembly/config</descriptorSourceDirectory>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>

assembly 配置文件实现(dev为例)

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd"> <id>config-dev</id>
<formats>
<format>zip</format>
<format>tar.gz</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<fileSets>
<fileSet>
<directory>${assemble.directory}/dev</directory>
<outputDirectory>/${project.version}</outputDirectory>
<lineEnding>unix</lineEnding>
<fileMode>0644</fileMode>
<directoryMode>0755</directoryMode>
<includes>
<include>**/*</include>
</includes>
</fileSet>
</fileSets>
</assembly>

如果需要对配置文件做处理，那么还需要使用maven-release-plugin对src/conf/下面的文件夹内容做处理，比如拷贝conf到target对应的folder，这样assembly的diretory也要跟着修改。

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.5</version>
<executions>
<execution>
<id>dev-config</id>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/deploy/config-dev</outputDirectory>
<resources>
<resource>
<directory>${basedir}/conf/dev</directory>
<filtering>true</filtering>
<includes>
<include>*.properties</include>
<include>*.xml</include>
</include>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
