程序中用了FormFile，报上面的错，后面发现是jsp页面上，要在提交的地方：

 <FORM id=frmpic name=frmpic action="addPhoto.do" onsubmit="return check()"  method=post

        encType=multipart/form-data>

加上：encType=multipart/form-data，否则报上面的错误

表单元素中的   enctype   属性规定了传递给服务器的表数据集编码的内容类型。enctype   属性的默认值是“application/x-www-form-urlencoded”，但当向服务器传送大量文本、包含非ASCII字符或二进制数的数据时，这个默认类型就不能胜任hq了。这时，文件上载提交表单时应使用“multipart/form-data”内容类型。
