As you can see, the bean has been tagged as
Named [1]
, which means that it can be dir-
ectly referenced in our JSF pages. The bean is
SessionScoped [2]
since it stores the
amount of money available to the customer during its session.
We would also like to inject
logger [3]
and
FacesContextFacexContexts
[5]
instead of manually defining it. To do this, we will need to register a bean that pro-
duces loggers, which are parameterized with the name of the class. We will cover this pro-
cess of producing beans in a moment.
