Class AutoProxyUtils

Field Detail

• 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).

  See Also:

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

• ORIGINAL_TARGET_CLASS_ATTRIBUTE

  public static final 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.

  Since:

  4.2.3

Method Detail

• shouldProxyTargetClass

  public static boolean shouldProxyTargetClass​(ConfigurableListableBeanFactory beanFactory,
                                               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

  public 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.

  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
