mybatis if判断

mybatis <if test=" "></if> 判断语句关键字智能用小写，不识别大写

<when test="(unit_number != null and unit_number != '') OR (business_code != null and business_code != '') ">

Caused by: org.apache.ibatis.ognl.ParseException: Encountered " "OR “” at line 1

 

正确写法：

<when test="(unit_number != null and unit_number != '') or  (business_code != null and business_code != '') ">

 

 

【<if test="takeWay == '0'">】mybatis的if判断

单个的字符要写到双引号里面才行，改为<if test='takeWay == "1"'>或者改为<if test="takeWay == '1'.toString() ">
