dao.getEntity(TableInfo.class).getField(orderByColumn); dao.getEntity 除此之外 还有没有方法 可以获取
定义抽象类 封装不同数控 查询表 那么问题来了
MappingField field =dao.getEntity(TableInfo.class).getField(orderByColumn);
这个类 没有dao 有没有方法可以替代 dao.getEntity(TableInfo.class)

public class MySqlQuery extends AbstractDbQuery {


    @Override

        if (Strings.isNotBlank(tableName)) {
            sqlstr += "and table_name like @tableName";
        }
