I have a singleton service object which looks something like this..
@Singleton
public class DAO {
private ElasticsearchTemplate template;
public DAO(Configuration config) {
// some initialisation code
}
}
and I made guice aware of this in my Module like this...
public class DAOModule extends AbstractModule {
@Override
protected void configure() {
bind(DAO.class).asEagerSingleton();
}
}
The above setup works great, and without any problems.
Now, I have another module which looks like this..
public class EmailModule extends AbstractModule {
public EmailModule(Environment env, Configuration config) {
// init code
}
@Override
protected void configure() {
Mail client = new Mail() // I want to pass the dao service to this
bind(Mail.class).toInstance(client);
}
}
If you look at EmailModule, part of the issue is I can't change the
constructor to receive additional parameter since PlayFramework by default
only seems to pass those.
If I try something like
@Provides
DAO getDAO(Injector injector) {
return injector.getInstance(DAO.class);
}
I get a "A binding to DAO was already configured at DAOModule.getDAO"
My question is, how do I get an instance of DAO into EmailModule?
