mybatis的错误,将sql放在Navicat中执行都可以
然后在<select></select>中写一个简单sql,发起情求,sql可以执行,说明mapper映射与resultMap还有parmaterType等没有错误
将sql的字段一个一个的字段进行删除然后执行,判断是哪个字段出错,最后找出是
SUM(o.service_type!=‘TC‘) AS repair_number,
这个字段,仿佛是mybatis不支持 SUM(列名)的格式
最后将这个字段修改为:
(select count(service_type) from or_rescue_order oro where service_type!="TC" and o.id = oro.id) AS repair_number,
就可以了
