先看错误代码:
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: com.baomidou.mybatisplus.core.exceptions.MybatisPlusException: Error: Method queryTotal execution error.
### The error may exist in com/dao/Class_ShipinDAO.java (best guess)
### The error may involve defaultParameterMap
### The error occurred while setting parameters
### Cause: com.baomidou.mybatisplus.core.exceptions.MybatisPlusException: Error: Method queryTotal execution error.

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<Class_Shipin> queryWrapper = new QueryWrapper<Class_Shipin>();
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
