7.10.4 Using filters to customize scanning
By default, classes annotated with @Component
, @Repository
, @Service
, @Controller
, or a custom annotation that itself is annotated with @Component
are the only detected candidate components. However, you can modify and extend this behavior simply by applying custom filters. Add them as includeFilters or excludeFiltersparameters of the @ComponentScan
annotation (or as include-filter or exclude-filter sub-elements of the component-scan
element). Each filter element requires the type
and expression
attributes. The following table describes the filtering options.
Filter Type | Example Expression | Description |
---|---|---|
annotation (default) |
org.example.SomeAnnotation
|
An annotation to be present at the type level in target components. |
assignable |
org.example.SomeClass
|
A class (or interface) that the target components are assignable to (extend/implement). |
aspectj |
org.example..*Service+
|
An AspectJ type expression to be matched by the target components. |
regex |
org\.example\.Default.*
|
A regex expression to be matched by the target components class names. |
custom |
org.example.MyTypeFilter
|
A custom implementation of the org.springframework.core.type .TypeFilter interface.
|
The following example shows the configuration ignoring all @Repository
annotations and using "stub" repositories instead.
@Configuration @ComponentScan(basePackages = "org.example", includeFilters = @Filter(type = FilterType.REGEX, pattern = ".*Stub.*Repository"), excludeFilters = @Filter(Repository.class)) public class AppConfig { ... }
