java - Singleton service solves multi-process writing files

Question

Now we need a multi-process file writing program

If you write directly, you need to ensure that the process locks the file handle

Now I want to register a singleton writing service through spring

When multiple programs write files, they request the spring interface to write files

Is this solution feasible?

Or use a singleton RPC service?

A single instance can ensure that it is an instance when writing a file, avoiding multi-thread and multi-process synchronization problems!
