  classes(), pattern()

  默认值:

  org.springframework.context.annotation.FilterType.ANNOTATION

• value

  @AliasFor("classes")
  Class<?>[] value

  Alias for classes().

  classes()

  默认值:

  {}

• classes

  @AliasFor("value")
  Class<?>[] classes

  The class or classes to use as the filter.

  The following table explains how the classes will be interpreted based on the configured value of the type() attribute.

  FilterType	Class Interpreted As
  ANNOTATION	the annotation itself
  ASSIGNABLE_TYPE	the type that detected components should be assignable to
  CUSTOM	an implementation of TypeFilter

  When multiple classes are specified, OR logic is applied — for example, "include types annotated with @Foo OR @Bar".

  Custom TypeFilters may optionally implement any of the following Aware interfaces, and their respective methods will be called prior to match:

  • EnvironmentAware
  • BeanFactoryAware
  • BeanClassLoaderAware
  • ResourceLoaderAware

  Specifying zero classes is permitted but will have no effect on component scanning.

  {}

• pattern

  String[] pattern

  The pattern (or patterns) to use for the filter, as an alternative to specifying a Class value().

  If type() is set to ASPECTJ, this is an AspectJ type pattern expression. If type() is set to REGEX, this is a regex pattern for the fully-qualified class names to match.
