    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.
    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(infra.beans.factory.config.ConfigurableBeanFactory beanFactory, String beanName)
    Determine the original target class for the specified bean, if possible, otherwise falling back to a regular getType lookup.
    (专用程序包) static void
    exposeTargetClass(infra.beans.factory.config.ConfigurableBeanFactory beanFactory, String beanName, Class<?> targetClass)
    Expose the given target class for the specified bean, if possible.
    (专用程序包) static boolean
    isOriginalInstance(String beanName, Class<?> beanClass)
    Determine whether the given bean name indicates an "original instance" according to AutowireCapableBeanFactory.ORIGINAL_INSTANCE_SUFFIX, skipping any proxy attempts for it.
    static boolean
    shouldProxyTargetClass(infra.beans.factory.config.ConfigurableBeanFactory beanFactory, String beanName)
    Determine whether the given bean should be proxied with its target class rather than its interfaces.

    • 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).

    • shouldProxyTargetClass

      public static boolean shouldProxyTargetClass(infra.beans.factory.config.ConfigurableBeanFactory 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.
      参数:
      beanFactory - the containing ConfigurableBeanFactory
      beanName - the name of the bean
      返回:
      whether the given bean should be proxied with its target class

    • determineTargetClass

      @Nullable public static Class<?> determineTargetClass(infra.beans.factory.config.ConfigurableBeanFactory beanFactory, @Nullable String beanName)
      Determine the original target class for the specified bean, if possible, otherwise falling back to a regular getType lookup.
      参数:
      beanFactory - the containing ConfigurableBeanFactory
      beanName - the name of the bean
      返回:
      the original target class as stored in the bean definition, if any

      static void exposeTargetClass(infra.beans.factory.config.ConfigurableBeanFactory beanFactory, @Nullable String beanName, Class<?> targetClass)
      Expose the given target class for the specified bean, if possible.
      参数:
      beanFactory - the containing ConfigurableBeanFactory
      beanName - the name of the bean
      targetClass - the corresponding target class

    • isOriginalInstance

      参数:
      beanName - the name of the bean
      beanClass - the corresponding bean class
