            <version>1.16</version>
        </dependency>

2. root-context수정

    <!-- HikariCP Configuration -->
    <bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
        <property name="driverClassName" value="net.sf.log4jdbc.sql.jdbcapi.DriverSpy" />
        <property name="jdbcUrl" value="jdbc:log4jdbc:postgresql://localhost:5433/postgres"/>
        <property name="username" value="postgres"/>
        <property name="password" value="egis"/>
        <property name="maximumPoolSize" value="10"/>
        <property name="minimumIdle" value="2"/>
        <property name="idleTimeout" value="30000"/>
