Class AnnotatedBeanDefinitionReader

java.lang.Object

org.springframework.context.annotation.AnnotatedBeanDefinitionReader

public class AnnotatedBeanDefinitionReader
extends Object

Convenient adapter for programmatic registration of annotated bean classes. This is an alternative to ClassPathBeanDefinitionScanner, applying the same resolution of annotations but for explicitly registered classes only.

Constructor Detail

AnnotatedBeanDefinitionReader

public AnnotatedBeanDefinitionReader(BeanDefinitionRegistry registry)

Create a new AnnotatedBeanDefinitionReader for the given registry. If the registry is EnvironmentCapable, e.g. is an ApplicationContext, the Environment will be inherited, otherwise a new StandardEnvironment will be created and used.

Parameters:

registry - the BeanFactory to load bean definitions into, in the form of a BeanDefinitionRegistry

AnnotatedBeanDefinitionReader(BeanDefinitionRegistry, Environment), setEnvironment(Environment)

AnnotatedBeanDefinitionReader

public AnnotatedBeanDefinitionReader(BeanDefinitionRegistry registry,
                                     Environment environment)

Create a new AnnotatedBeanDefinitionReader for the given registry and using the given Environment.

Parameters:

registry - the BeanFactory to load bean definitions into, in the form of a BeanDefinitionRegistry

environment - the Environment to use when evaluating bean definition profiles.

Since:

3.1

Method Detail

getRegistry

public final BeanDefinitionRegistry getRegistry()

Return the BeanDefinitionRegistry that this scanner operates on.

setEnvironment

public void setEnvironment(Environment environment)

Set the Environment to use when evaluating whether @Conditional-annotated component classes should be registered.

The default is a StandardEnvironment.

See Also:

registerBean(Class, String, Class...)

setBeanNameGenerator

public void setBeanNameGenerator(@Nullable
                                 BeanNameGenerator beanNameGenerator)

Set the BeanNameGenerator to use for detected bean classes.

The default is a AnnotationBeanNameGenerator.

setScopeMetadataResolver

public void setScopeMetadataResolver(@Nullable
                                     ScopeMetadataResolver scopeMetadataResolver)

Set the ScopeMetadataResolver to use for detected bean classes.

The default is an AnnotationScopeMetadataResolver.

register

public void register(Class<?>... annotatedClasses)

Register one or more annotated classes to be processed.

Calls to register are idempotent; adding the same annotated class more than once has no additional effect.

Parameters:

annotatedClasses - one or more annotated classes, e.g. @Configuration classes

registerBean

public void registerBean(Class<?> annotatedClass)

Register a bean from the given bean class, deriving its metadata from class-declared annotations.

Parameters:

annotatedClass - the class of the bean

registerBean

public <T> void registerBean(Class<T> annotatedClass,
                             @Nullable
                             Supplier<T> instanceSupplier)

Register a bean from the given bean class, deriving its metadata from class-declared annotations, using the given supplier for obtaining a new instance (possibly declared as a lambda expression or method reference).

Parameters:

annotatedClass - the class of the bean

instanceSupplier - a callback for creating an instance of the bean (may be null)

Since:

5.0

registerBean

public <T> void registerBean(Class<T> annotatedClass,
                             String name,
                             @Nullable
                             Supplier<T> instanceSupplier)

Register a bean from the given bean class, deriving its metadata from class-declared annotations, using the given supplier for obtaining a new instance (possibly declared as a lambda expression or method reference).

Parameters:

annotatedClass - the class of the bean

name - an explicit name for the bean

instanceSupplier - a callback for creating an instance of the bean (may be null)

Since:

5.0

registerBean

public void registerBean(Class<?> annotatedClass,
                         Class<? extends Annotation>... qualifiers)

Register a bean from the given bean class, deriving its metadata from class-declared annotations.

Parameters:

annotatedClass - the class of the bean

qualifiers - specific qualifier annotations to consider, in addition to qualifiers at the bean class level

registerBean

public void registerBean(Class<?> annotatedClass,
                         String name,
                         Class<? extends Annotation>... qualifiers)

Register a bean from the given bean class, deriving its metadata from class-declared annotations.

Parameters:

annotatedClass - the class of the bean

name - an explicit name for the bean

qualifiers - specific qualifier annotations to consider, in addition to qualifiers at the bean class level
