一 问题描述
用户反馈无法前台查询数据，报错500，后台查看日志如下，使用的是ibatis+oracle连接方式：
09:05:56 INFO - atomikos connection proxy for oracle.jdbc.driver.LogicalConnection@24367013: close()...
09:05:56 ERROR - 获取店内自己分类的列表数据发生异常~

二 分析思路
1.检查sql.xml配置没有问题，字段和sql语句正常
2.检查jdbc.xml配置文件，查看数据库配置，登录对应数据库，检查表shop，发现shop下面确实没有此字段IS_DEFAULT
三 解决方法
添加shop下的这个字段即可（之前忘记添加了）
检查数据库：
SQL> desc shop
Name Null? Type
----------------------------------------- -------- ----------------------------
SHOP_ID NOT NULL NUMBER(22)
MODIF_USER NUMBER(22)
EXEC_SQL VARCHAR2(250)
IS_EXPANDALL VARCHAR2(2)
正常情况：
SQL> desc shop
Name Null? Type
----------------------------------------- -------- ----------------------------
SHOP_ID NOT NULL NUMBER(22)
MODIF_USER NUMBER(22)
EXEC_SQL VARCHAR2(250)
IS_EXPANDALL VARCHAR2(2)
IS_DEFAULT VARCHAR2(2)
