//略 set get

看上去是没判断@Name是否为null

貌似是个bug？

  public <T> T fetch(T obj) {
        Entity<?> en = holder.getEntityBy(obj);
//错误源于下面这句
        Pojo pojo = pojoMaker.makeQuery(en)
                             .append(Pojos.Items.cndAuto(en, obj))
                             .setAfter(_pojo_fetchEntity)
                             .setPager(createPager(1, 1));
        _exec(pojo);
        return (T) pojo.getResult();
    }

看上去像bug，我看看怎么改

我发现你没把报错信息贴全:
