public class AnnotationConfigApplicationContext extends GenericApplicationContext implements AnnotationConfigRegistry
@Configuration
-annotated classes, but also plain
@Component
types and JSR-330 compliant
classes using javax.inject
annotations. Allows for registering classes one by
one using register(Class...)
as well as for classpath scanning using
scan(String...)
.
In case of multiple @Configuration
classes, @Bean
methods defined in
later classes will override those defined in earlier classes. This can be leveraged to
deliberately override certain bean definitions via an extra @Configuration
class.
See @Configuration
's javadoc for usage examples.

AnnotationConfigApplicationContext()
Create a new AnnotationConfigApplicationContext that needs to be populated
through
register(java.lang.Class<?>...) calls and then manually refreshed. |
AnnotationConfigApplicationContext(java.lang.Class<?>... annotatedClasses)
Create a new AnnotationConfigApplicationContext, deriving bean definitions
from the given annotated classes and automatically refreshing the context.
|
AnnotationConfigApplicationContext(DefaultListableBeanFactory beanFactory)
Create a new AnnotationConfigApplicationContext with the given DefaultListableBeanFactory.
|
AnnotationConfigApplicationContext(java.lang.String... basePackages)
Create a new AnnotationConfigApplicationContext, scanning for bean definitions
in the given packages and automatically refreshing the context.

void |
register(java.lang.Class<?>... annotatedClasses)
Register one or more annotated classes to be processed.
|
<T> void |
registerBean(java.lang.Class<T> annotatedClass,
java.lang.Object... constructorArguments)
Register a bean from the given bean class, deriving its metadata from
class-declared annotations, and optionally providing explicit constructor
arguments for consideration in the autowiring process.
|
<T> void |
registerBean(java.lang.String beanName,
java.lang.Class<T> annotatedClass,

java.util.function.Supplier<T> supplier,
BeanDefinitionCustomizer... customizers)
Register a bean from the given bean class, using the given supplier for
obtaining a new instance (typically declared as a lambda expression or
method reference), optionally customizing its bean definition metadata
(again typically declared as a lambda expression or method reference).

should also be considered. In either case, such modifications
should be performed before AbstractApplicationContext.refresh()
