<!-- 根据用户名和账户搜索用户 --> <select id="selectUserByLoginnameAndShowName" parameterClass="java.util.Map" resultMap="resultUsers"> SELECT a.USER_ID ,a.LOGIN_NAME ,a.PASS_WORD ,a.SHOW_NAME ,a.PASS_WORD ,a.CREATE_TIME ,a.GROUP_ID ,a.ADMIN_FLG ,b.ID ,b.GROUP_NAME ,b.HIDE_FLG FROM table_user as a LEFT JOIN table_group AS b ON b.ID = a.GROUP_ID <dynamic prepend="WHERE"> <isNotEmpty prepend="AND" property="loginName"> a.LOGIN_NAME LIKE '%$loginName$%' </isNotEmpty> <isNotEmpty prepend="AND" property="showName"> a.SHOW_NAME LIKE '%$showName$%' </isNotEmpty> <isNotNull property="fromIndex"> <isNotNull property="pageSize"> LIMIT #fromIndex# , #pageSize# </isNotNull> </isNotNull> </dynamic> ORDER BY a.USER_ID DESC </select>
请问我这哪里错了？

------解决方案--------------------
Column 'USER_ID' not found.数据库有这个字段？
------解决方案--------------------
检查下resultMap="resultUsers">对应的属性是否正确
------解决方案--------------------
感觉没有什么问题，请楼主加下log4j配置
log4j.logger.java.sql.Connection = DEBUG
log4j.logger.java.sql.Statement = DEBUG
log4j.logger.java.sql.PreparedStatement = DEBUG
log4j.logger.java.sql.ResultSet = DEBUG
查看出错前执行的sql语句，返回的结果时，按字面意思理解就是查询出结果了，但在进行resultmap映射时出错....
