쿼리가 일정시간 없다가 쿼리를 수행하면

Caused by: org.mariadb.jdbc.internal.util.dao.QueryException: Could not read resultset: unexpected end of stream, read 0 bytes from 4라는 오류가 발생하는데 원인은 timeout이므로 DBCP connection pool 속성에 validationQuery에 SELECT 1를 지정하고 testOnBorrow = true를 지정해준다.

예)

        <property name="validationQuery" value=" select 1" />
        <property name="testOnBorrow" value="true" />
