Fields

Modifier and Type	Field	Description
static final String	ORIGINAL_TARGET_CLASS_ATTRIBUTE	Bean definition attribute that indicates the original target class of an auto-proxied bean, for example, to be used for the introspection of annotations on the target class behind an interface-based proxy.
static final 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).

static Class<?>	determineTargetClass(ConfigurableListableBeanFactory beanFactory, 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, String beanName)	Determine whether the given bean should be proxied with its target class rather than its interfaces.

Field Details

PRESERVE_TARGET_CLASS_ATTRIBUTE

public static final 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).

ORIGINAL_TARGET_CLASS_ATTRIBUTE

public static final String ORIGINAL_TARGET_CLASS_ATTRIBUTE

Method Details

shouldProxyTargetClass

public static boolean shouldProxyTargetClass(ConfigurableListableBeanFactory beanFactory,
 @Nullable
 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 Class<?> determineTargetClass(ConfigurableListableBeanFactory beanFactory,
 @Nullable
 String beanName)

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

Since:

4.2.3
