Yes I do see the log (catalina.out) shows
IAccount: DEFINED
IAuthService: DEFINED
And what makes me confused is that the log also shows that the IAccount is
created when invoking AuthService.java
[DEBUG] AppModule.IAccount Creating service 'IAccount'.
[AuthService.java] accountDAO is null?<Proxy for
Account(org.example.domain.IAccount)> //printed by System.out.println
But when it comes to execute RdbmsLogin.java, the '@private IAccount
accountDAO' in RdbmsLogin becomes null because I use System.out.println() to
print the object accountDAO (accountDAO.findUserByAccount(new User("-1",
account, "", password));) and the result is as follow:
[RdbmsLogin.java] accountDAO is null? null
The flow of execution is
Login.java -> IAuthService.java/ AuthService.java -> RdbmsLogin.java
in AuthService and Rdbmslogin both contain '@Inject private IAccount
accountDAO' annotation; but the accountDAO in AuthService is not null and I can
execute the function e.g. findUserByAccount without a problem. Unfortunately,
when it execute accountDAO in RdbmsLogin, then the accountDAO is null. (This is
just for comparison so I put two Inject annotation in AuthService and
RdbmsLogin classes)
Also, if I remove IAuthService/ AuthService, directly calling RdbmsLogin.java
from Login.java shows the accountDAO ('@Inject private IAccount accountDAO') in
RdbmsLogin.java is still null. (This execution flow should be Login.java ->
RdbmsLogin.java )
The AppModule.java contains the binding clauses
public class AppModule {
public static void bind(ServiceBinder binder) {
binder.bind(IAuthService.class, AuthService.class);
binder.bind(IAccount.class, Account.class);
}
...
}
I think I may do something wrong, but I completely am not aware of it. Is there
anything I miss or misconfigure?
Thanks in advice.
