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.

• value()
• type()

默认值:

{}

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 REGEX, this is a regex pattern for the fully-qualified class names to match.
