springMVC使用multipartFile上传文件出错：MultipartHttpServletRequest: is a MultipartResolver configured?
1 2 3 4 5 6 7 8 | 17-Apr-2016 22:36:27.171 SEVERE [http-apr-8080-exec-4] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [dispatcher] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalArgumentException: Expected MultipartHttpServletRequest: is a MultipartResolver configured?] with root cause java.lang.IllegalArgumentException: Expected MultipartHttpServletRequest: is a MultipartResolver configured? |
这是因为找不到multipartReslover的原因，这很搞笑，在springMVC配置文件配置它的时候，不能用其他名字，只能用指定名字，否则就出现这种找不到的错误。
出错例子：
改正例子：
一定要用multipartResolver这个id名。
