OK, so here's what I'd do.
Initialize one sqlmapclient instance per locale, pass in the locale as
a property when you initialize it, and use the property notation
${locale} in your sql maps to substitute the value when the sql map is
created.
Create a ThreadLocalSqlMapFactory:
===
public class ThreadLocalSqlMapFactory {
private static ThreadLocal<SqlMapClient> threadLocal = new
ThreadLocal<SqlMapClient>();
public static SqlMapClient getClient(){
return threadLocal.get();
}
public static void setClient(SqlMapClient client){
threadLocal.set(client);
}
}
===
Create a Filter that looks at the current user's session, if there is
no locale there, set it to the default. If there is a locale there,
get it. In either case, at this point the user's session has a locale
on it. Use that to look up the sqlmapclient for that locale and set it
on the ThreadLocalSqlMapFactory (above). Call the filter chain in a
try block, and in the finally, set the ThreadLocalSqlMapFactory's
SqlMapClient property to null.
Now, anywhere in your code that you need a SqlMapClient, you can call
the static method to get the one that is stored on the current thread.
You could probably use a proxy to make it even more transparent (and I
think you could even plug it in with Spring), but you'd have to hire
me for a few hours to get me to write that code for you.
Email me off-list if you are interested in doing that. :-D
