profile:
[要点:] activeByDefault默认激活,不用再mvn命令时指定额外参数;
[注意:] 使用非默认的配置,要在编译时指定:如,要在生产环境打包[并跳过单元测试]:
mvn clean package -Pproduct [-Dmaven.test.skip=ture]
如果mvn clean package:
a. 默认加载profile-dev.properties来打包
b. 可以替换的内容范围是:
src/main/resources/.xml|.properties...
src/main/java/.xml
<project>
<build>
<finalName>project-name</finalName>
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>/</include>
</includes>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>*/.xml</include>
</includes>
</resource>
</resources>
</build><profiles>
<profile>
<id>dev</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<build>
<filters>
<filter>profile-dev.properties</filter>
</filters>
</build>
</profile><!-- 2.测试环境 --> <profile> <id>test</id> <build> <filters> <filter>profile-test.properties</filter> </filters> </build> </profile> <!-- 3.UAT环境 --> <profile> <id>uat</id> <build> <filters> <filter>profile-uat.properties</filter> </filters> </build> </profile> <!-- 4.生产环境 --> <profile> <id>product</id> <build> <filters> <filter>profile-product.properties</filter> </filters> </build> </profile>
</profiles>

用法:
比如profile-dev.properties文件中定义了
mvn.mysql.url.mydb=jdbc:mysql://localhost:3306/mydb
mvn.mysql.user.mydb=root
mvn.mysql.pass.mydb=1234
那么可以在其他公用配置文件中使用${}来引用profile-dev.properties中的属性,比如:
(1). db.properties中:
db.url=${mvn.mysql.url.mydb}
db.user=${mvn.mysql.user.mydb}
db.pass=${mvn.mysql.pass.mydb}
(2) spring-ds.xml中:(用法1)
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<property name="url" value="${mvn.mysql.url.mydb}"/>
<property name="username" value="${mvn.mysql.user.mydb}"/>
<property name="password" value="${mvn.mysql.pass.mydb}"/>
</bean>
spring-ds.xml中,也可以使用这样:(用法2-引用再引用)
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<property name="url" value="${db.url}"/>
<property name="username" value="${db.user}"/>
<property name="password" value="${db.pass}"/>
</bean>
