public class AnnotationConfigApplicationContext extends GenericApplicationContext
@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 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(Class<?>... annotatedClasses)
Create a new AnnotationConfigApplicationContext, deriving bean definitions
from the given annotated classes and automatically refreshing the context.
|
AnnotationConfigApplicationContext(String... basePackages)
Create a new AnnotationConfigApplicationContext, scanning for bean definitions
in the given packages and automatically refreshing the context.

Environment for this application context.
Default value is determined by AbstractApplicationContext.createEnvironment(). Replacing the
default with this method is one option but configuration through AbstractApplicationContext.getEnvironment() should also be considered. In either case, such modifications
should be performed before AbstractApplicationContext.refresh().
Delegates given environment to underlying AnnotatedBeanDefinitionReader
and ClassPathBeanDefinitionScanner members.

BeanNameGenerator for use with AnnotatedBeanDefinitionReader
and/or ClassPathBeanDefinitionScanner, if any.
Default is AnnotationBeanNameGenerator.
Any call to this method must occur prior to calls to register(Class...)
and/or scan(String...).
public void setScopeMetadataResolver(ScopeMetadataResolver scopeMetadataResolver)
ScopeMetadataResolver to use for detected bean classes.
The default is an AnnotationScopeMetadataResolver.
Any call to this method must occur prior to calls to register(Class...)
and/or scan(String...).
public void register(Class<?>... annotatedClasses)
AbstractApplicationContext.refresh() must be called in order for the context to fully
process the new class.
Calls to register(java.lang.Class<?>...) are idempotent; adding the same
annotated class more than once has no additional effect.
