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