MyBatis-plus报错:Error evaluating expression ‘ew.sqlSegment != null
·
报错信息
Caused by: org.apache.ibatis.builder.BuilderException: Error evaluating expression 'ew.sqlSegment != null '. Cause: org.apache.ibatis.ognl.OgnlException: sqlSegment [com.baomidou.mybatisplus.core.exceptions.MybatisPlusException: not support this column !]
问题重现
QueryWrapper ew = new QueryWrapper();
ew.likeRight(StringUtils.isNotEmpty(projectCardNumber),projectCardNumber);
List<FinishedProductInStockVO> list = baseMapper.selectFinishedProductInStockVO(ew,
searchParam, startInTime, endInTime);
报错原因
ew.likeRight(boolean condition,object cloumn,object value)
参数传递有误
少传一个参数!!
更正
ew.likeRight(StringUtils.isNotEmpty(projectCardNumber), "t2.project_card_number", projectCardNumber);
问题报错:ew.sqlSegment != null 很容易误解为ew的传参问题,但确实也是它的问题,可以通过debug查看ew的expression 中的normal 属性是否被赋值
来查看条件是否生效
