A CMS project for the new company is to be used, which is recorded here

I. Project Document Map

Second, springmvc-servlet.xml add

<!--define environment variable files--    <bean id= "Propertyholder" class= " Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer ">        <property name=" Systempropertiesmodename "value=" System_properties_mode_override "/>        <property name=" Ignoreresourcenotfound "value=" true "/>        <property name=" Locations ">            <list>                <value >classpath*:/*.properties</value>            </list>        </property>    </bean>
