mybatis数据库查询的几种常见方法

queryWrapper.and(!CollectionUtils.isEmpty(req.getWorkshopCodes()), wrapper -> {
            for (String paramType : req.getWorkshopCodes()) {
                wrapper.or().eq(DeviceShiftInfo::getWorkshopCode, paramType);
            }
        });
SQL:  (workshop_code = '测试1'	OR workshop_code = '测试2')
      queryWrapper.in(!CollectionUtils.isEmpty(req.getWorkshopCodes()),DeviceShiftInfo::getWorkshopCode,req.getWorkshopCodes())            
 SQ：workshop_code IN('测试1','测试2')

queryWrapper.and(!CollectionUtils.isEmpty(req.getWorkshopCodes()), wrapper -> {
            for (String paramType : req.getWorkshopCodes()) {
                wrapper.or()
                        .apply("FIND_IN_SET({0}, workshop_code)", paramType);
            }
        });
SQL:WHERE	((FIND_IN_SET('1', workshop_code) OR FIND_IN_SET('2', workshop_code)))

queryWrapper.and(!CollectionUtils.isEmpty(req.getWorkshopCodes()), wrapper -> {
            for (String paramType : req.getWorkshopCodes()) {
                wrapper.or().like(DeviceShiftInfo::getWorkshopCode, paramType);
            }
        });
SQL: WHERE ((workshop_code LIKE '%1%' OR workshop_code LIKE '%2%'))

WHERE 	((JSON_OVERLAPS(remark,	'["1","2"]'))) 只要数据库字段的数组存在查询集合的值则就会被返回
