DYNAMIC_SCHEME(ÊǶ¯Ì¬Ôö¼Ó.ÓÃÍêÈç¹û³¬¹ýÉÏÏÞÔò¹Øµô)
The cache will create connections above the specified maximum limit
when necessary   but will in turn close connections as they are
returned to the cache until the number of  connections is within the
maximum limit. Connections will never be cached above the  maximum
limit. This is the default setting.
FIXED_RETURN_NULL_SCHEME  (Ö±½Ó·µ»ØNull)
The cache will return a null connection once the maximum connection limit has been  exceeded.
FIXED_WAIT_SCHEME  (ʼÖյȴý)
The cache will wait until there is a connection available and will then return it to the  calling application.
