How to pass parameter value to aspect - spring-aop

Question

How do we get the parameter value(uId) from calling method(deleteTask) of JointPoint(in logJdbcOperation)? I am able to log sql statement and sql parameters but cannot find a way to log value of uId.
Please, guide me.
public int deleteTask(String taskname, String uId) {
String sql = "delete from shedlock where NAME= :name";
MapSqlParameterSource namedParameters = new MapSqlParameterSource();
((MapSqlParameterSource) namedParameters).addValue("name", taskname, Types.VARCHAR);
return namedJdbcTemplate.update(sql, namedParameters);
}
#Aspect
#Component
public class LoggingAspect {
private static final Logger LOGGER = LogManager.getLogger(LoggingAspect.class);
#Before("execution(* org.springframework.jdbc.core..NamedParameterJdbcOperations.*(String, ..))")
public void logJdbcOperation(JoinPoint jp) {
Object[] methodArgs = jp.getArgs();
String statement = methodArgs[0].toString();
MapSqlParameterSource params = (MapSqlParameterSource)methodArgs[1];
LOGGER.debug("SQL statement:" + statement);
}
}

The code shared does not show how the uId is passed on to the method namedJdbcTemplate.update(sql, namedParameters). It is not possible to get the parameter to the calling method . Any parameter of the target method can be obtained.
Following code would advice the method deleteTask and get the arguments passed to it.
#Around("execution(* package.deleteTask(..)) && args(taskName,uId)")
public Object logDeleteTask(ProceedingJoinPoint pjp, String taskName, String uId) {
LOGGER.debug("Task Name :" + taskName);
LOGGER.debug("Uid :" + uId);
Object ret = 0;
try {
ret = pjp.proceed();
} catch (Throwable e) {
// handle exception if any
}
return ret;
}

Note : Remember to modify the package.deleteTask(..) to approrpriate package name.
