spring+mybatis+druid+mysql为啥会报：spring xml model Validation

Question

小白小连一下，求各路大神指教：用的idea开发spring+mybatis+druid+mysql
spring+mybatis+druid为啥为啥会报：spring xml model Validation ，
其中加粗字体报spring xml model Validation
而换c3p0不会有spring xml model Validation
我的具体配置如下：
applicationcontext.xml:
<?xml version="1.0" encoding="UTF-8"?>

<!--开启注解 -->

<!--扫包 -->

<!-- 读取jdbc配置 -->
<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

            <!-- jdbc.properties引入-->
            <value>classpath:jdbc.properties</value>
        </list>
    </property>
</bean>

<!--数据库连接池  druid-->

    <!--读取值 ${key}-->
    <property name="**driverClass**" value="${driverClass}" /> 
    <property name="**jdbcUrl**" value="${jdbcUrl}"></property>
    <property name="**user**" value="${user}" />
    <property name="password" value="${password}" />
</bean>

<!--Mybatis操作数据库 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <!--连数据库 -->
    <property name="dataSource" ref="dataSource" />
    <!--xml位置 -->
    <property name="mapperLocations" value="classpath:com/cgwllx/lxfood/dao/***.xml**" />
    <!--PO别名 -->
    <property name="typeAliasesPackage" value="com.cgwllx.lxfood.dao" />

</bean>

<!-- 扫包 扫xml -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.cgwllx.lxfood.dao" />
</bean>

项目结构：

jdbc.properties为：
driverClass=mysql.jdbc.Driver

jdbcUrl=mysql://localhost:3306/energizecloud?useUnicode=true&characterEncoding=utf8

user=root

password=1234

pom也引入了该有的依赖：
