上传文件时出错"Unable to process parts as no multi-part configuration has been provided"

Question

我试图通过JSP文件中的表单上传文件，但我得到这个错误。servlet已经有了@MultipartConfig表示法。我使用servlet 3.0和apache tomcat 8。

错误信息:

java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided

行

Collection<Part> parts = request.getParts();`

Answer 1

我必须添加

allowCasualMultipartParsing="true"

on context tag inside text.xml
