Class Jsr330ScopeMetadataResolver

java.lang.Object
org.springframework.context.annotation.Jsr330ScopeMetadataResolver
All Implemented Interfaces:
ScopeMetadataResolver
public class Jsr330ScopeMetadataResolver extends Object implements ScopeMetadataResolver
Simple ScopeMetadataResolver implementation that follows JSR-330 scoping rules: defaulting to prototype scope unless Singleton is present.

This scope resolver can be used with ClassPathBeanDefinitionScanner and AnnotatedBeanDefinitionReader for standard JSR-330 compliance. However, in practice, you will typically use Spring's rich default scoping instead - or extend this resolver with custom scoping annotations that point to extended Spring scopes.

    • registerScope

      public final void registerScope(Class<?> annotationType, String scopeName)
      Register an extended JSR-330 scope annotation, mapping it onto a specific Spring scope by name.
      Parameters:
      annotationType - the JSR-330 annotation type as a Class
      scopeName - the Spring scope name

    • registerScope

      public final void registerScope(String annotationType, String scopeName)
      Register an extended JSR-330 scope annotation, mapping it onto a specific Spring scope by name.
      Parameters:
      annotationType - the JSR-330 annotation type by name
      scopeName - the Spring scope name

    • resolveScopeName

      protected @Nullable String resolveScopeName(String annotationType)
      Resolve the given annotation type into a named Spring scope.

      The default implementation simply checks against registered scopes. Can be overridden for custom mapping rules, for example, naming conventions.

      Parameters:
      annotationType - the JSR-330 annotation type
      Returns:
      the Spring scope name

    • resolveScopeMetadata

      public ScopeMetadata resolveScopeMetadata(BeanDefinition definition)
      Description copied from interface: ScopeMetadataResolver
      Resolve the ScopeMetadata appropriate to the supplied bean definition.

      Implementations can of course use any strategy they like to determine the scope metadata, but some implementations that spring immediately to mind might be to use source level annotations present on the class of the supplied definition, or to use metadata present in the AttributeAccessor.attributeNames() of the supplied definition.

      Specified by:
      resolveScopeMetadata in interface ScopeMetadataResolver
      Parameters:
      definition - the target bean definition
      Returns:
      the relevant scope metadata; never null
