Singleton behavior not achieved - spring

Question

I have a #Component like below:
#Component
public class FilenetConnection {
#Value("${filenet.url}")
String url;
#Value("${filenet.username}")
String username;
#Value("${filenet.password}")
String password;
#Bean
public Connection getCPEConnection() {
try {
Connection conn = Factory.Connection.getConnection(url);
Subject subject = UserContext.createSubject(conn, username, password, "FileNetP8WSI");
UserContext uc = UserContext.get();
uc.pushSubject(subject);
System.out.println("CE Connection" + conn);
return conn;
} catch (Exception ex) {
ex.printStackTrace();
}
return null;
}
}
And in my RestController this is how I am trying to access the Bean method getCPEConnection() return value:
#Autowired
ConfigurableApplicationContext applicationContext;
public FilenetConnection getBeanOfBaseComponent() {
return applicationContext.getBean(FilenetConnection.class);
}
Now everytime I access the bean method's return value using getBeanOfBaseComponent().getCPEConnection() a new object for conn from the (Singleton) #Bean getCPEConnection() is returned. What I am missing here?

Answer 1

So I understand that you do something like this:
You call getBeanOfBaseComponent() and there you get the Instance of FilenetConnection and on this instance you call getCPEConnection().
If I understood this correct it makes sense that it doesn't work.
Because you don't use the bean you just call a normal method which returns you a new Instance of Connenction.
So I don't use this way of accessing beans myself but I guess you need to use applicationContext.getBean(Connection.class); to be able to use the Connection bean.
Or another and easier solution would be to just inject the Connection into your Controller class.
And normally you define beans in classes annotated with #Configuration and not #Component
