It is necessary to use File.separator, as the file path separator on other OS may not be '/'.

The UTs also need to be modified accordingly.

Sorry, it was my oversight. I have modified it as required. Please review it again. Thank you.

By the way, is there any compatibility issue here? From the code, it seems that there isn't.

Do you mean file path separator in test case? I also have this doubts but the other use cases I refer to in this file are like this.

Sorry, there are indeed some compatibility issues in my UTs, I have located the problem in the workflows. I will provide a new patch after completing the test in my repository later.

Fixes #8859
Brief Description
I changed the key of the requestTable in the AllocateMappedFileService class from the FilePath to the FileName(this must be the only one), and then added a getCachedMappedFilePath method to provide to the MultiPathMappedFileQueue to check whether the MappedFile of a specified offset MappedFile create request has been submitted, and if so, obtain the cached FilePath, otherwise a new path is generated based on the previous rules.
How Did You Test This Change?
I make a unit test to recurrence this case in testUniqueNextNextMappedFile().
In the previous implementation, the results obtained were as shown in the picture below, the MappedFile 00000000000000001024 repeatedly appear in directory a and directory b.
This problem was solved in the new implementation and the result is as follows:
