spring - Can I programatically add a qualifier to a bean? -

i registering transaction managers in code, utilize annotation based configuration don't know until runtime how many info sources (and hence transaction managers) there be, have programatically register these, follows:

private final void registertransactionmanagerbean(final datasource datasource, configurableapplicationcontext context) {

string transactionmanagername = this.getname() + "-transactionmanager"; context.getbeanfactory().registersingleton(transactionmanagername, new datasourcetransactionmanager(datasource)); log.info("registering transaction manager under name : " + transactionmanagername);

}

assuming this.getname() returned 'mydb', expected able qualify transacton manager this:

@transactional("mydb-transactionmanager")

what i've realised value of annotation refers qualifier , not name. did quick test declaring bean below , works:

@bean @qualifier("mydb-transactionmanager") public platformtransactionmanager test() { homecoming new datasourcetransactionmanager(new embeddeddatabasebuilder().build()); }

my question is, there way can programatically add together qualifier when registering bean?

much appreciated.

update

i've worked out, i'm falling foul of problem (in beanfactoryannotationutils:isqualifiermatch):

catch (nosuchbeandefinitionexception ex) { // ignore - can't compare qualifiers manually registered singleton object }

i manually registering transaction manager bean presume why i'm stuck. i'm not sure options gives me apart not programatically register transaction managers runtime thing sadly.
