每个项目都会有多套运行环境,最基本的就是Dev、QA、Prod,不同的环境对应的配置也不尽相同,比如说数据库连接,文件路径,WebServices address 等等。
不同环境下需要构建不同的包,那么我们可以通过以下两种方式来解决:
一、定义多个 pom,使用 -f <pom_file> 指定
e.g.
pom.xml (default)
pom_qa.xml
pom_prod.xml
Build war for qa:
mvn clean package -f pom_qa.xml
Build war for product:
mvn clean package -f pom_prod.xml
多个 pom.xml 之间重复配置很多,不容易维护,极不推荐这种方式。
二、结合 maven-war-plugin 和 profile 进行配置
需求假设:
1) 不同环境的数据库连接地址以及 DataSource 类型不一样
开发环境通过普通的DataSource连接数据库:
<bean name="SQLServerDriverDS" destroy-method="close">
<property name="driverClassName" value="${driver_class}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
<property name="url" value="${url}" />
<property name="maxIdle" value="${maxPoolSize}" />
<property name="maxActive" value="${minPoolSize}" />
</bean>
测试和产品环境都是通过 JNDI 方式连接数据库:
<bean id="SQLServerDriverDS">
<property name="jndiName" value="jdbc/AlteraDS" />
</bean>
2) 不同环境的 log4j.properties 不同,文件上传下载路径也不一样。
3) QA 的 war 包名称要带上日期,e.g. xxx-20120830.war
为了实现上述需求,组织工程目录结构如下:
project/
`-- src
|-- main
| |-- java
| |-- env
| | |-- dev
| | | |-- log4j.properties
| | | |-- spring-dataSource.xml
| | | `-- variable.propertes
| | |-- prod
| | | |-- log4j.properties
| | | |-- spring-dataSource.xml
| | | `-- variable.propertes
| | `-- qa
| | |-- log4j.properties
| | |-- spring-dataSource.xml
| | `-- variable.propertes
| |-- resources
| `-- webapp
`-- test
pom.xml里定义三个环境的profile:
<profile>
<id>dev</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<runtime.env>src/main/env/dev</runtime.env>

Maven-war-plugin里配置additional resource folder
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1.1</version>
<configuration>
<overlays>
<overlay>
<groupId>TransactionResource</groupId>
<artifactId>TransactionResource</artifactId>
<excludes>
<exclude>WEB-INF/web.xml</exclude>
</excludes>
</overlay>
</overlays>
<webResources>
<resource>
<directory>${runtime.env}</directory>
<targetPath>WEB-INF/classes</targetPath>
</resource>
</webResources>
</configuration>
</plugin>
<finalName>${final.name}</finalName>
${runtime.env} & ${final.name}就是profile里定义的两个properties。
打包的时候使用-P <profile>指定需要打哪个环境的包。
e.g.
mvn clean package -Pdev
mvn clean package -Pqa
