aspectj - spring aop - exception while creating advice around JdbcTemplate methods -

i've web application uses apache dbcp , spring jdbc perform database operations on oracle database. need write performance logger logs individual times of each database operation. tried writing around advice on 'execute' methods of org.springframework.jdbc.core.jdbctemplate results in error when spring gets initialized. logger class , exception stacktrace follows:-

i tried use cglib proxies enabling errors out on dao classes extends spring's storedprocedure class , use constructor injection.

@aspect public class logger {  @around("this(org.springframework.jdbc.core.jdbctemplate) && execution(* execute(*))") public object invoke(proceedingjoinpoint pjp) throws throwable {     long time = system.currenttimemillis();     object result = pjp.proceed();     logger.debug("time consumed = " + (system.currenttimemillis() - time));     return result; } 

exception stacktrace:
