问题描述

mybatis中sql问题求解决

在mysql客户端中执行下面语句

 select
            sk.seckill_id,
            sk.user_phone,
            sk.create_time,
            sk.state,
            s.seckill_id "seckill.seckill_id",
            s.name "seckill.name",
            s.number "seckill.number",
            s.start_time "seckill.start_time",
            s.end_time "seckill.end_time",
            s.create_time "seckill.create_time"
        from success_killed sk
        inner join seckill s on sk.seckill_id = s.seckill_id
where sk.seckill_id=1 and sk.user_phone=13573615842

没有报错，但是配置在mybatis的xml中会出现下面的错误
信息: Loading XML bean definitions from class path resource [org/springframework/jdbc/support/sql-error-codes.xml]
五月 21, 2016 10:50:17 上午 org.springframework.jdbc.support.SQLErrorCodesFactory

信息: Closing org.springframework.context.support.GenericApplicationContext@4351aa16: startup date [Sat May 21 10:50:16 CST 2016]; root of context hierarchy

求解释

解决方案

mybatis sql 映射文件问题

解决方案四：

数据库里添加的数据库类型不一样，看看那个属性的数据类型不一致
