com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException错误解决

### Error querying database.  Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL
syntax; check the manual that corresponds to your MySQL server version for the right 
syntax to use near 'role.id as roleId,role.role_name as roleNames,role.right_names as 
rightNames' at line 10

这个错误一看就是sql语句出错,但是我一直没有找到错误原因。

最后挨个查看SQL语句中字段后,发现有个pwd字段前后都没有逗号(,)。

原因是mybatis配置中

<include refid="Base_Column_List" />
<include refid="Blob_Column_List" />
<include refid="AccountRoleVo_Column_List" />

引用的sql片段没有用逗号隔开

改为下面的就可以了:

<include refid="Base_Column_List" />,
<include refid="Blob_Column_List" />,
<include refid="AccountRoleVo_Column_List" />

总结:遇到sql语句问题,最好还是挨个查看sql是否写错。写配置文件时也应该细心。积累经验。
