上传图片ioerror
① android 上传图片报此异常java.io.EOFException 求大神指点
这个我在部署到tomcat的时候遇到过这个情况，不知道和你的是否一样，我的处理方法
apache-tomcat-6.0.37\work\Catalina\localhost，把你的项目删除，重新跑一遍，tomcat中的错误是因为有一个文件在启动的时候会短暂的出现，然后被删除，如果没有删除就会报eofe 的异常
② 上传图片，实现图片压缩 java.lang.IllegalArgumentException: Can't load standard profile: GRAY.pf

③ ueditor上传图片报IO错误，怎么破
用FTP软件，修改上传照片后存放的目录权限为777，不行就全部777，最后检查下图片上传限制改为最大值。配置文件：
config.json
{
/* 上传图片配置项 */
"imageActionName": "uploadimage", /* 执行上传图片的action名称 */
"imageFieldName": "upfile", /* 提交的图片表单名称 */
"imageMaxSize": 2048000, /* 上传大小限制，单位B */
"imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], /* 上传图片格式显示 */
"imageCompressEnable": true, /* 是否压缩图片,默认是true */
"imageCompressBorder": 1600, /* 图片压缩最长边限制 */
"imageInsertAlign": "none", /* 插入的图片浮动方式 */
"imageUrlPrefix": "http://127.0.0.1:8080", /* 图片访问路径前缀 */
"imagePathFormat": "/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */
/* {filename} 会替换成原文件名,配置这项需要注意中文乱码问题 */
/* {rand:6} 会替换成随机数,后面的数字是随机数的位数 */
/* {time} 会替换成时间戳 */
/* {yyyy} 会替换成四位年份 */
/* {yy} 会替换成两位年份 */
/* {mm} 会替换成两位月份 */
/* {dd} 会替换成两位日期 */
/* {hh} 会替换成两位小时 */
/* {ii} 会替换成两位分钟 */
/* {ss} 会替换成两位秒 */
/* 非法字符 \ : * ? " < > | */
/* 具请体看线上文档: fex..com/ueditor/#use-format_upload_filename */
运行后报错如下：

④ 传照片出现IO Error错误是什么意思
IO
Error
完整翻译就是
I
Input
输入，
O
Output
输出，Error
错误，就是说输入或者输出的通讯错误，可能是连接线问题，也可能是存储卡问题。
⑤ webuploader分片上传的实现代码（前后端分离）
本文介绍了webuploader分片上传的实现代码（前后端分离），分享给大家，具体如下：
WebUploader是由Bai
WebFE(FEX)团队开发的一个简单的以HTML5为主，FLASH为辅的现代文件上传组件。在现代的浏览器里面能充分发挥HTML5的优势，同时又不摒弃主流IE浏览器，沿用原来的FLASH运行时，兼容IE6+，iOS
6+,
android
4+。两套运行时，同样的调用方式，可供用户任意选用。采用大文件分片并发上传，极大的提高了文件上传效率。(这个是从官网上直接的解释)
功能描述
1、webuploader是网络研发的上传组件，文档不是特别规整，但是也够用了。
2、前端使用官网的上传图片demo，在此基础上代码略微调整做分片。既可以上传图片也可以上传文件。文件超过分片大小才启用分片。
3、分片上传已做md5校验，达到秒传的效果。分片以后需要合并，可以先分片后合并，也可以边分片边合并，本示例采用的是边分片边合并的方案。
4、后端用springboot做框架搭建。springMVC做rest服务，开启跨域访问。
5、容器用springboot内置的tomcat插件，运行Application的main方法即可启动服务；
