Druid database connection pool overflow

druid database connection overflows, resulting in application downtime. The database uses Ali Cloud"s RDS, connection to allow 8000 connections

connection pool is configured as follows :

<!--  -->
    <bean id="dataSourceMain" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
        <!-- DruidURLDriverClass -->
        <property name="driverClassName" value="${dataSourceMain.driver}"/>
        <property name="url" value="${dataSourceMain.url}"/>
