Question

我的ApplicationContext.xml中有以下属性。它应该使用附加的System.getProperty（＆＃34; Environment＆＃34;）值从类路径加载文件。

<context:property-placeholder location="classpath*:MyConfigFile-${ENVIRONMENT}.properties"/>

当我的Spring-context架构为：

时，这是有效的

http://www.springframework.org/schema/context/spring-context-3.0.xsd

但不是设置为：

http://www.springframework.org/schema/context/spring-context-4.0.xsd

或设置为：

http://www.springframework.org/schema/context/spring-context-3.2.xsd

我已使用配置文件中的值替换了下面的变量值，并且所有内容都适用于4.0架构。

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-    method="close">
        <property name="driverClass" value="oracle.jdbc.driver.OracleDriver"/>
        <property name="jdbcUrl" value="${url}"/>
        <property name="user" value="${username}"/>
        <property name="password" value="${password}"/>
        <property name="maxPoolSize" value="15"/>
    <property name="minPoolSize" value="5"/>
</bean>

任何建议？

编辑我得到以下例外情况：
