application.xml

<bean id ="Config" class="com.jmev.web.util.config.Config">
   <property name="type"  value="${config.environment}"></property>
</bean>

<bean id ="MyConfig" class="com.jmev.web.util.config.ConfigUtils"></bean>

部分pom,在<profile><id>local</id></profile> <properties中進行配置自定義屬性>

<config.environment>local/localConfig.properties</config.environment>

在<profile><id>product</id></profile> <properties中進行配置自定義屬性>

<config.environment>product/productConfig.properties</config.environment>

resources目錄下 分別加

local/localConfig.properties

product/productConfig.properties

就OK,裡面分別是本地和生產。
