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.
|
| Modifier and Type | Method and Description |
|---|---|
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.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> beanClass,
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).
|
void |
scan(java.lang.String... basePackages)
Perform a scan within the specified base packages.
|
void |
setBeanNameGenerator(BeanNameGenerator beanNameGenerator)
Provide a custom
BeanNameGenerator for use with AnnotatedBeanDefinitionReader
and/or ClassPathBeanDefinitionScanner, if any. |
void |
setEnvironment(ConfigurableEnvironment environment)
Propagates the given custom
Environment to the underlying
AnnotatedBeanDefinitionReader and ClassPathBeanDefinitionScanner. |
void |
setScopeMetadataResolver(ScopeMetadataResolver scopeMetadataResolver)
Set the
ScopeMetadataResolver to use for detected bean classes. |

BeanNameGenerator for use with AnnotatedBeanDefinitionReader

Default is AnnotationBeanNameGenerator.
Any call to this method must occur prior to calls to register(Class...)

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...)

public void register(java.lang.Class<?>... annotatedClasses)
Note that AbstractApplicationContext.refresh() must be called in order for the context
