Javax.imageio.IIOException: Can't create cache file! File upload exception 15 Can't create cache 48 Can't create cache file 21.374 [http-bio-80-exec-438] file upload exception: file upload javax.imageio.IIOException: file! At javax.imageio.ImageIO.createImageOutputStream (Unknown Source)... Caused by: java.nio.file.NoSuchFileException: d:\ apache-tomcat-7.0.85\ temp\ imageio5123082028978377437.tmp at sun.nio.fs.WindowsException.translateToIOException (Unknown Source).

Caused by file not found: java.nio.file.NoSuchFileException: xxx... The main reason for / temp/imageio4138671232726624650.tmp is that when operating with the imgio package, the cache directory: ${tomcat} / temp is used by default, where the cache file and timestamp .tmp will be generated (this string of numbers should be the current timestamp and temporary file name), but some tomcat will delete the temp directory, so the error solution:

Create a new temp directory under the installation directory of tomcat

ImageIO.setCacheDirectory (cacheDirectory): sets any cache directory that exists

I prefer this method: ImageIO.setUseCache (false) to set, change cache policy, do not use file directory cache, use memory cache
