struts2自带的FileUploadInterceptor

Question

struts2本身会自带FileUploadInterceptor
如果我在action中再定义一个interceptor
interceptorRefs={@InterceptorRef(value="fileUpload",params={"allowedTypes","image/bmp,image/x-png,image/gif,application/pdf,image/pjpeg,text/plain,application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/octet-stream","maximumSize","19200"}),

@InterceptorRef("defaultStack")}

会执行二次interceptor，其实只是想执行一次action中的interceptor就可以了，
不知道该如何处理？

Answer 1

@InterceptorRef("defaultStack")}

defaultStack里面已经默认含有FileUploadInterceptor

所以会执行两次

可以自己重写defaultStack这个配置,去掉FileUploadInterceptor 或者是干脆就用defaultStack里面的FileUploadInterceptor,把action里的拦截器去掉
