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

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:

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：

是不是要取消xml校验..类似上图..不一定是那个..
