在MyBatis時，使用LIKE語句出錯：WHERE payed > 0 CONCAT(orderNumber, phone, IFNULL(dorm, ''), IFNULL(room,'')) LIKE '%#{content}%'

從錯誤看，類似數組超界的錯誤，是在解析上面的sql出錯的， '%#{content}%'，這里在解析出現的超界錯誤。

所以這個MyBatis的LIKE語句就不正確了，我從網上找到了LIKE的正確寫法：http://happyqing.iteye.com/blog/2172397

也看到了#和$的區別：http://www.cnblogs.com/friends-wf/p/4227999.html
