VMware 2V0-72.22 Exam - Topic 1 Question 89 Discussion
Topic #: 1
Given an ApplicationContext containing three bean definitions of type Foo with bean ids foo1, foo2, and foo3, which three @Autowired scenarios are valid and will allow the ApplicationContext to initialize successfully? (Choose three.)
The @Autowired annotation can be used to inject a dependency into a field, a constructor, or a setter method. However, if there are multiple beans of the same type in the application context, Spring will not be able to determine which one to inject by default. To resolve this ambiguity, we can use the @Qualifier annotation to specify the bean id of the desired dependency. Alternatively, we can use the bean id as the name of the field or the parameter of the setter method, and Spring will match it with the corresponding bean.
