Да, възможно е, защо да разчитате на код на някой друг, когато можете да създадете своя собствена JNDI фабрика? просто създайте клас, който имплементира javax.naming.spi.ObjectFactory и bean, който изтегля mongo от JNDI контекста, конфигурирах това за пролетни данни -mongo MongoTemplate обект.
public class CustomMongoJNDIFactory implements ObjectFactory {
public Object getObjectInstance(Object obj, Name name, Context nameCtx,
Hashtable<?, ?> environment) throws Exception {
validateProperty(obj, "Invalid JNDI object reference");
MongoTemplate mongoTemplate = null;
String db = null;
String host = null;
String username = null;
String password = null;
int port = 27017;
Reference ref = (Reference) obj;
Enumeration<RefAddr> props = ref.getAll();
while (props.hasMoreElements()) {
RefAddr addr = (RefAddr) props.nextElement();
String propName = addr.getType();
String propValue = (String) addr.getContent();
if (propName.equals("db")) {
db = propValue;
} else if (propName.equals("host")) {
host = propValue;
} else if (propName.equals("username")) {
username = propValue;
} else if (propName.equals("password")) {
password = propValue;
} else if (name.equals("port")) {
try {
port = Integer.parseInt(propValue);
} catch (NumberFormatException e) {
throw new NamingException("Invalid port value " + propValue);
}
}
}
// validate properties
validateProperty(db, "Invalid or empty mongo database name");
validateProperty(host, "Invalid or empty mongo host");
validateProperty(username, "Invalid or empty mongo username");
validateProperty(password, "Invalid or empty mongo password");
//create mongo template
mongoTemplate = new MongoTemplate(new Mongo(host, port), db,
new UserCredentials(username, password));
return mongoTemplate;
