static java.lang.Class<?>	determineTargetClass(ConfigurableListableBeanFactory beanFactory, java.lang.String beanName) Determine the original target class for the specified bean, if possible, otherwise falling back to a regular getType lookup.
static boolean	shouldProxyTargetClass(ConfigurableListableBeanFactory beanFactory, java.lang.String beanName) Determine whether the given bean should be proxied with its target class rather than its interfaces.

Field Detail

PRESERVE_TARGET_CLASS_ATTRIBUTE

public static final java.lang.String PRESERVE_TARGET_CLASS_ATTRIBUTE

Bean definition attribute that may indicate whether a given bean is supposed to be proxied with its target class (in case of it getting proxied in the first place). The value is Boolean.TRUE or Boolean.FALSE.

Proxy factories can set this attribute if they built a target class proxy for a specific bean, and want to enforce that bean can always be cast to its target class (even if AOP advices get applied through auto-proxying).

shouldProxyTargetClass(org.springframework.beans.factory.config.ConfigurableListableBeanFactory, java.lang.String)

ORIGINAL_TARGET_CLASS_ATTRIBUTE

public static final java.lang.String ORIGINAL_TARGET_CLASS_ATTRIBUTE

Bean definition attribute that indicates the original target class of an auto-proxied bean, e.g. to be used for the introspection of annotations on the target class behind an interface-based proxy.

Method Detail

shouldProxyTargetClass

public static boolean shouldProxyTargetClass(ConfigurableListableBeanFactory beanFactory,
                                             @Nullable
                                             java.lang.String beanName)

Determine whether the given bean should be proxied with its target class rather than its interfaces. Checks the "preserveTargetClass" attribute of the corresponding bean definition.

Parameters:

beanFactory - the containing ConfigurableListableBeanFactory

beanName - the name of the bean

Returns:

whether the given bean should be proxied with its target class

determineTargetClass

@Nullable
public static java.lang.Class<?> determineTargetClass(ConfigurableListableBeanFactory beanFactory,
                                                                @Nullable

Determine the original target class for the specified bean, if possible, otherwise falling back to a regular getType lookup.

Parameters:

beanFactory - the containing ConfigurableListableBeanFactory

beanName - the name of the bean

Returns:

the original target class as stored in the bean definition, if any

4.2.3
