不支持“multiple”方式
<form>
<input name="file" type="file" multiple="multiple" />
</form>
形式控件上传文件,该方式相当于
<form>
<input name="file" type="file" />
<input name="file" type="file" />
</form>
如果按上述设置,文件能全部上传,但是FileUploadRequest的getFile(s)方法只能对相同name值的多个input标签返回一个UploadFile对象,即只能获取到最后的一个文件的信息。
后期可能需要研究其他接收文件的jar包,以及HTTP协议,从而找出是否能解决该问题以及如何解决
上传文件太大,后台会报错
IOException:Posted content length of ... exceeds limit of ...
并停止文件接收,response不回应,导致前端报错
POST ... net::ERR_CONNECTION_ABORTED
此时如果使用ajax上传问会执行error函数,Jfinal的做法应该是报错后继续接收文件流直到完成,再回应前端(待验证)
