YYGH-BUG-03

Today, I am working on a picture uploading system , When integrating qiniu cloud, an error is reported when uploading a file
org.springframework.web.multipart.MaxUploadSizeExceededException: Maximum upload size exceeded; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes.
By analyzing the problem, we know that this is because , The uploaded picture is too big
At this time, the scanning needs to modify the configuration file
spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=10MB

Now we need to upgrade the production business by adding a randomly generated image to the image uuid

                String uuid = UUID.randomUUID().toString().replace("-", "");
                String fileName = uuid + file.getOriginalFilename();

Then store the files in the folders corresponding to the dates

                String uuid = UUID.randomUUID().toString().replace("-", "");
                String fileName = uuid + file.getOriginalFilename();
                String timeUrl = new DateTime().toString("yyyy/MM/dd");
                fileName = "/" + timeUrl + "/" + fileName;
                Response response = uploadManager.put(file.getInputStream(), fileName, upToken, null, null);   

Insert picture description here
