maven自动选择不同的配置文件打包profile+filter
[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> <!-- 启用filter功能为resources中的变量赋值 --> <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> <!-- 1.开发环境 --> <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> </project>
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>
