Annotation Type EnableBeanContext

@Target(value=TYPE)
 @Retention(value=RUNTIME)
 @Documented
 @Import(value=com.holonplatform.spring.internal.context.BeanFactoryScopeRegistrar.class)
public @interface EnableBeanContext

Setup a Context scope using Spring application context (or in exact terms, using the application context BeanFactory) to provide context resource instances as Spring beans.

When a context resource is requested (using Context.resource(String, Class)), the scope strategy to provide a matching Spring bean is defined as follow:

• If a Spring bean with a name equal to the context resource key and with the same required type is found, this is returned;
• Otherwise, if lookupByType() is true and a Spring bean of the required type, ignoring the name, is present and only one candidate is available, this instance is returned.

The Spring BeanFactory behaviour is preserved during beans lookup, so, for example, Spring beans scopes strategy is applied, just like bean retrieval using BeanFactory.getBean(String, Class) and similar methods.

public static final String LOOKUP_BY_TYPE_PROPERTY_NAME

Property which can be used to configure the lookupByType() behaviour using a Spring Environment configuration property. If setted, overrides the lookupByType() annotation attribute value.

Element Detail

lookupByType

public abstract boolean lookupByType

Whether to lookup context resource bean candidates by type, ignoring bean name, when default lookup by name and type fails. Only consistent type beans with a single instance retuned by BeanFactory are taken into account.

Returns:

true to lookup context resource bean candidates by type ignoring bean name and context resource key match

Default:

true
