To solve this problem, all uploaded code may be stored in a folder. We can store the uploaded code in folders.

Simpledateformat SDF = new simpledateformat ("/yyyy/mm/DD/"); // splicing path string basepath = servletactioncontext. getservletcontext (). getrealpath ("/WEB-INF/upload_files"); string subpath = SDF. format (new date (); string Path = basepath + subpath + UUID. randomuuid (); // use UUID to solve the problem of file name duplication. // If the folder does not exist, create file dir = new file (basepath + subpath); If (! Dir. exists () {dir. mkdirs ();} // move the file upload. renameto (new file (PATH); // rename or move a file. if the directory file already exists or the directory folder does not exist, the system will return the falsereturn path if the migration fails;
