问题已经解决。ssl 传输对数据进行加密。大于 2m 的参数解析，需要升级证书

首先不会是 Nginx 的问题。 因为常规的 http 请求可以成功，且如果是 nginx 的错误会有 log 日志，浏览器也会报错。然后关于 tomcat，能够收到请求，只是字段的值没有传过来。客服指的收费，是因为我们使用的是阿里的 ca 免费证书，证书文件是他们给的。

有人吗

楼主好可怜啊 哈哈哈哈哈

@wesley 嗯 我也是这样想的 但怎样实现呢，数据全部取出来再计算比较吗？

求助，，

select w.xm,w.wgfwzb,COUNT(case x.username when x.xqzt=1 then 1 else 0 end ) '已完成需求总数'
from t_wgy w left join t_sq_xqdj x on w.sjh=x.wgytel group by w.sjh ;

select w.xm,w.wgfwzb,COUNT(x.username ) '需求总数'
from t_wgy w left join t_sq_xqdj x on w.sjh=x.wgytel group by w.sjh ;
这样写的。但查出来的有误

另外 谢谢上面的回复 提出意见

额之前没想好需求，现在整理了一下
1 ：散热不能差，基本每天使用电脑 10 小时以上。
2 ：外观不能太 low ，不要太笨重，最好是金属外壳。
3: 内存 8G 以上，屏幕最好是 14 寸。
4 ：处理器 显卡没特别要求， Lol 能开中配就行
5 ：预算在 5k~6.5k 之间。最好是新上市的电脑。

@DualWield 为什么呢 小白一枚

@shliujing 我毕业后就一直用 jfinal 现在换了新公司 感觉还不如刚刚毕业的时候了。

有人帮忙吗 一上午了

建表的时候 就应该有备用字段吧
