换成 @AdaptBy(type = WhaleAdaptor.class) 不报错 但是 接受不到图片

总有人想用ajax上传文件。。。

用ajaxfileupload,webupload等前端插件

呃 应该是这样
直接用jquery的ajax是不能上传文件的.
这时候, 你需要 jquery ajax upload, webupload等第三方js文件上传插件, 它们会通过iframe/flash/html5 file api等技术来实现ajax文件上传.
PS: 据说最新版的jquery支持了走html5 file api进行上传,但我没验证过,暂时当它不行, 估计你也不会用那么高版本的jquery.

关键是这个上传怎么解决的?在你那个开源项目里,出现和你一样的错误.

用ajaxfileupload等js插件

@menglinxi 改成用表单提交 或者 用ajaxfileupload等js插件
