spring MVC 使用maven 区分环境配置

首先需要两套配置文件，后缀用-dev ，-prod区分。我的目录结构

 

 

1.首先在pom文件中引入

这个放在<build>标签后面，跟<build>同级

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42

<!-- 打包的不同profile --> <profiles>    <!-- 开发 -->    <profile>       <id>dev</id>       <properties>          <env>dev</env>       </properties>       <activation><activeByDefault>true</activeByDefault></activation>    </profile>    <!-- 生产 -->    <profile>       <id>prod</id>       <properties>          <env>prod</env>       </properties>      </profile> </profiles>       这个在<build>标签下 <resources>    <resource>       <directory>src/main/resources</directory>       <excludes>          <exclude>             *.properties          </exclude>       </excludes>    </resource>      <resource>       <directory>src/main/resources</directory>       <includes>          <include>config-${env}.properties</include>          <include>log4j.properties</include>       </includes>    </resource>   </resources>

　　

 

2.然后在context.xml 文件中 引入，这里俩都引进来，但是只会生效一个。

<context:property-placeholder     file-encoding="utf-8"    ignore-resource-not-found="true"    ignore-unresolvable="false"     location="      classpath:/config-prod.properties ,classpath:/config-dev.properties"/>
