Spring MVC and Kindeditor integration

When using the Spring MVC Framework and then using Kindeditor, there will be an upload error. The reason is that the upload.parserequest (request) value is always null. Because the request obtained at this time is the defaultmultiparthttpservletrequest type. The original processing upload pictures of the upload_json.jsp file can not be used, so kindeditor in the process of uploading images of the upload_json.jsp file to rewrite. This is the rewritten upload_json.jsp file.
