maven+eslipse 多环境打包 profiles

我们经常需求对不同的环境打不同的包

比如，测试环境包，线上环境包

这意味着不同的环境，配置参数不同，同时我们还想对打包的包名进行个性化命名

所以我们就逐步讲解利用maven进行这种需求的打包

1.pom.xml的profile配置 :位置在project下面

<project>
<profiles>
<profile>
<id>test</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<p.jdbc.url>127.0.0.1:3306</p.jdbc.url>
<p.jdbc.dbname>test_trunk</p.jdbc.dbname>
<p.jdbc.username>root</p.jdbc.username>
<p.jdbc.password>123456</p.jdbc.password>
<p.package.suffix>test</p.package.suffix>
</properties>
</profile>
<profile>
<id>production</id>
<properties>
<p.jdbc.url>10.5.121.186:23325</p.jdbc.url>
<p.jdbc.dbname>db_prod</p.jdbc.dbname>
<p.jdbc.username>root</p.jdbc.username>
<p.jdbc.password>root</p.jdbc.password>
<p.package.suffix>prod</p.package.suffix>
</properties>
</profile>
</profiles>
</project>

上面的配置是对不同环境数据库的配置，以及包名后缀进行了属性配置，并且对打包的输出包名的后缀进行了个性化的配置。

2. 对于profile标签，我们还需要有个.properties文件，持有这些变量，例如:config.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\://${p.jdbc.url}/${p.jdbc.dbname}?useUnicode\=true&characterEncoding\=UTF-8&zeroDateTimeBehavior\=convertToNull&rewriteBatchedStatements\=true
jdbc.username=${p.jdbc.username}
jdbc.password=${p.jdbc.password}

3. 对config.properties文件打包时替换成配置值注意：必须有filtering

红色部分加上，否则会出现配置文件没有打包进去

<build>

<resource>
<directory>src/main/resources/conf</directory>
<includes>
<include>**/*</include>
</includes>
</resource>
<resource>
<directory>src/main/resources/conf</directory>
<includes>
<include>config.properties</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>

</build>

4. 打包

mvn clean package -p production

结果：config.properties中${}值替换成 profile中的属性值

5. 可以将profile中的属性值放在一个文件中过滤文件（separatefile）

<project>
<profiles>
<profile>
<id>kaifa</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<build>
<filters>
<filter>${basedir}/filters/kaifa/param.txt</filter>
</filters>
</build>
</profile>
<profile>
<id>shengchan</id>
<build>
<filters>
<filter>${basedir}/filters/shengchan/param.txt</filter>
</filters>
</build>
</profile>
</profiles>
<build>
<resources>
          <resource>
             <filtering>true</filtering>
              <directory>src/main/resources</directory>
             <includes>
                 <include>db.proerties</include>
             </includes>
          </resource>
</resources>
</build>
</project>

param.txt：

name=world

还可以这样子哦：

<project>
<profiles>
<profile>
<id>kaifa</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<build>
<properties>
<filters.env>kaifa</filters.env>
</properties>
</build>
</profile>
<profile>
<id>shengchan</id>
<build>
1. <properties>
2. <filters.env>shengchan</filters.env>
3. </properties>
</build>
</profile>
</profiles>
<build>
<resources>
          <resource>
             <filtering>true</filtering>
              <directory>src/main/resources</directory>
             <includes>
                 <include>db.proerties</include>
             </includes>
          </resource>
</resources>
1. <filters>
2. <filter>${basedir}/filters/${filters.env}/param.txt</filter>
3. </filters>
</build>
</project>
