Today, the ability to upload files, and to record the current time as the upload time, but found in the Java New Date () and the time after the format problem, can not be stored in the database, for example: Today is July 31, 2014, the time is 6:51 P.M. 42 seconds, but the output is 2014-51-31 06:51:42, first of all, the month is certainly wrong, and secondly, 6

ThinkingWhy not just write the absolute path?A: In our actual development process is basically a team development, with the help of SVN and other code synchronization. We cannot guarantee that the storage path of each local project is consistent, some may be in the D drive, some in the E drive. The above approach ensures that the path ahead of the project is dynamically fetched, and that the owner's local project storage location is different and does not aff
