同学你好。这边测试你的代码，是可以提示提交失败的：

http://img1.sycdn.imooc.com//climg/5d0627cf0001330c14670725.jpg

失败的原因是获取详情图失败，在执行addImageHolder方法时

http://img1.sycdn.imooc.com//climg/5d0629110001742712500401.jpg

http://img1.sycdn.imooc.com//climg/5d062bf00001740513790621.jpg

由于multipartHttpServletRequest
中存储的是productImg0所以得不到此productImageList

http://img1.sycdn.imooc.com//climg/5d0629350001cb0308220149.jpg

同学你好。这个报错

http://img1.sycdn.imooc.com//climg/5d076c6a0001611c06000213.jpg

实际的报错位置在这里

 http://img1.sycdn.imooc.com//climg/5d076c8f000138e405990111.jpg

实质上是因为basePath中含有空格等特殊字符，在转码的时候会出现“乱码”。比如这里我的路径有空格，就被解析为了“%20”

有两种解决方式，一是使用URLDecoder.decode(basePath,”UTF-8”);但实测这种不能解决“+”等运算符

 http://img1.sycdn.imooc.com//climg/5d076cc600012a7306000123.jpg

建议使用下面这种，将basePath赋值处使用如下方式：

http://img1.sycdn.imooc.com//climg/5d076cd100018a1606000115.jpg

 

就可以解决EOF的问题了。

如果解答了同学的疑问，望采纳~

祝学习愉快~

同学你好。

1、Eclipse中设置超时时间，可以先点击红色方格停一下Tomcat服务器。http://img1.sycdn.imooc.com//climg/5d060c470001a42c01750073.jpg

双击Tomcat服务器，然后在弹出的窗口中，展开Timeouts，将其修改后。使用Ctrl+S保存一下，然后再重启。

http://img1.sycdn.imooc.com//climg/5d060b9e0001d5bf11740523.jpg

2、同学这里是不是拼写错了呢？如果同学的标签没有修改，应该是productImg

private ImageHolder addImageHolder(ImageHolder thumbnail, List<ImageHolder> productImageList,

MultipartHttpServletRequest multipartHttpServletRequest = (MultipartHttpServletRequest) request;

CommonsMultipartFile thumbnailFile = (CommonsMultipartFile) multipartHttpServletRequest

.getFile("thumbnail");

//构建缩略图文件流和名字的对象

thumbnail = new ImageHolder(thumbnailFile.getOriginalFilename(),

thumbnailFile.getInputStream());

//获取详情图

for (int i = 0; i < IMAGMAXCOUNT; i++) {

CommonsMultipartFile productFile = (CommonsMultipartFile) multipartHttpServletRequest

.getFile("froductImg" + i);

if (productFile != null) {

ImageHolder productImg = new ImageHolder(productFile.getOriginalFilename(),

productFile.getInputStream());

//添加详情图进List

productImageList.add(productImg);

} else {

//若取出的第i个详情图片文件流为空，则终止循环

break;

}

}


return thumbnail;

}



我一步一步调试，确定返回true了 但是就没进 没有任何提示http://img1.sycdn.imooc.com//climg/5d060aca0001af6a10680259.jpg

    有关这个问题，可能和缓存有关系，同学添加@ResponseBody后有无重启Tomcat？如果还是不行，清除Eclipse编译缓存在Eclipse头部菜单栏中的 Project -> Clean... 清除服务器缓存在Servers窗口，选择自己的Tomcat服务器右键 Clean... 祝学习愉快~
