Create a HomeDirectoryResolver interface to Resolve a User's Home Directory
---------------------------------------------------------------------------
Key: FTPSERVER-335
URL: https://issues.apache.org/jira/browse/FTPSERVER-335
Project: FtpServer
Issue Type: Improvement
Reporter: Nick Padgett
It would be useful to have a HomeDirectoryResolver interface to resolve a
user's home directory. I use such a class to do the following:
1) Prefix a base path to user home directories. I have FtpServer deployed with
two different applications. In one applicationI need their home directory to
begin with "d:/mnt" and in the other I need "/mnt".
2) Allow users to share a common home directory (i.e. "d:/mnt/users").
3) Allow users to have private home directories (i.e. "d:/mnt/users/npadgett").
The interface I use looks something like:
<code>
public interface HomeDirectoryResolver {
String resolve(final User user);
}
</code>
The class I use looks something like:
<code>
public class HomeDirectoryResolverImpl implements HomeDirectoryResolver {
public static enum Strategy {
SHARED, USERNAME, HOME_DIRECTORY
}
private final String basePath;
private final Strategy strategy;
public HomeDirectoryResolverImpl(final String basePath,
final Strategy strategy) {
this.basePath = basePath;
this.strategy = strategy;
}
public String resolve(final User user) {
String homeDirectory = this.basePath
+ (this.basePath.endsWith("/") ? "" : "/");
switch (this.strategy) {
case SHARED:
// do nothing
break;
case USERNAME:
homeDirectory += user.getName();
break;
case HOME_DIRECTORY:
homeDirectory += user.getHomeDirectory();
break;
default:
throw new IllegalStateException();
}
return homeDirectory;
}
}
</code>
