jsp使用七牛云API和webuploader上传多组图片

介绍

前作:JavaWeb servlet jsp 使用七牛云API上传图片

使用mysql保存图片七牛云路径,在上传图片的时候直接上传到七牛云

前端使用了layui,图片多组上传使用了百度的WebUploader,本来想用swfupload的,但是10年前的东西实在不太行,我连跑都跑不起来…

另外我加入了log4j用来打日志

下面是简单演示

目录树

大致上是这样

webuploader里面只有dist用到

遇到的问题

上传组件的选择问题

swfupload实在是用不了,报错全部解决也不行,搜来搜去选择了WebUploader,至少是国人写的,好歹文档是中文,不至于看不懂

进度条

看着官网的示例有进度条,但是我这里没有,发现是css的问题,然后去百度加进去就好了

jsp使用七牛云API和webuploader上传多组图片_第1张图片

多线程

用这个组件后台会自动往你写的那个地址传东西,这个是并发的,如果不加锁结果老是不对,所以我在UploadServlet那里加了锁

前端界面

使用了layui来构建前端,包括日期组件也是layui自带的,挺好用的,用那个表单组件的时候差点卡住了,不过问题不大,看文档看懂就好了

数据库

从浏览器选择的日期传到后端再进行数据库的查询

关键代码

我将完整代码放到了

有兴趣的可以打个star

我这里只放关键代码,不然太多了
