Linux shows that the file can not be found abnormal how to solve? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Scene:

The project accesses normally under windows, but the linux throws an exception and the file cannot be found.

Analysis:

If the project file accessed is like this: abc/bcd/aa.jpg, and the path to the access file in the system is: abc/Bcd/aa.jpg, the difference between the two is that the secondary directory bcd is written as Bcd.

If you develop under windows, you can't find the error. The windows file name is case-insensitive, so you can still access the file according to abc/Bcd/aa.jpg, but the linux file directory is case-sensitive, so you can't find the file.

Solution:

In normal programming, you must write strictly.

It should also be noted that the linux directory separator is /, and under windows is\, so sometimes the file path stored in windows to the database will not be applicable to linux. It needs to be processed in the system. After the path is removed from the database, it needs to be processed as follows:

/ * modify the path, replace\\ or / with File.separator * @ param path path to be modified * @ return modified path * / public static String path (String path) {String p = StringUtils.replace (path, "\", "/"); p = StringUtils.join (StringUtils.split (p, "/"), "/") If (! StringUtils.startsWithAny (p, "/") & & StringUtils.startsWithAny (path, "\\", "/")) {p + = "/";} if (! StringUtils.endsWithAny (p, "/") & & StringUtils.endsWithAny (path, "\", "/")) {p = p + "/" } if (path! = null & & path.startsWith ("/")) {p = "/" + p; / / path under linux} return p } this is the answer to the problem of how to solve the problem when the linux display cannot find a file exception.
