问题原因:
是因为使用MyBatis Plus时, queryWrapper条件构造器的语法有错误
错误代码如下:
QueryWrapper queryWrapper = new QueryWrapper();
queryWrapper.ge(true, "shipin_upload_time", min_shipin_upload_time);
queryWrapper.le(true, "shipin_upload_time", max_shipin_upload_time);
改为正确为:
if(max_shipin_upload_time != null && max_shipin_upload_time.toString().length()>0)
queryWrapper.le(true, "shipin_upload_time", max_shipin_upload_time);
if(shipin_desc != null && shipin_desc.length()>0)
queryWrapper.eq(true, "shipin_desc", shipin_desc);
即使用queryWrapper的方法时 需要判断一下参数是否为空 长度是否大于0
