<!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->
    <property

/>

<!-- 配置监控统计拦截的filters，去掉后监控界面sql无法统计 -->
    <property name="filters"

</bean>

Web.xml配置文件中添加

<filter>
   
<filter-name>DruidWebStatFilter</filter-name>

</servlet>
<servlet-mapping>
   
<servlet-name>DruidStatView</servlet-name>
   
<url-pattern>/druid/*</url-pattern>
</servlet-mapping>
