public class AnnotationConfigWebApplicationContext extends AbstractRefreshableWebApplicationContext implements AnnotationConfigRegistry
WebApplicationContext
implementation which accepts annotated classes as input - in particular@Configuration
-annotated classes, but also plain@Component
classes and JSR-330 compliant classes usingjavax.inject
annotations. Allows for registering classes one by one (specifying class names as config location) as well as for classpath scanning (specifying base packages as config location).This is essentially the equivalent of
AnnotationConfigApplicationContext
for a web environment.To make use of this application context, the "contextClass" context-param for ContextLoader and/or "contextClass" init-param for FrameworkServlet must be set to the fully-qualified name of this class.
As of Spring 3.1, this class may also be directly instantiated and injected into Spring's
DispatcherServlet
orContextLoaderListener
when using the newWebApplicationInitializer
code-based alternative toweb.xml
. See its Javadoc for details and usage examples.Unlike
XmlWebApplicationContext
, no default configuration class locations are assumed. Rather, it is a requirement to set the "contextConfigLocation" context-param forContextLoader
and/or "contextConfigLocation" init-param for FrameworkServlet. The param-value may contain both fully-qualified class names and base packages to scan for components. SeeloadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory)
for exact details on how these locations are processed.As an alternative to setting the "contextConfigLocation" parameter, users may implement an
ApplicationContextInitializer
and set the "contextInitializerClasses" context-param / init-param. In such cases, users should favor theAbstractApplicationContext.refresh()
andscan(String...)
methods over theAbstractRefreshableConfigApplicationContext.setConfigLocation(String)
method, which is primarily for use byContextLoader
.Note: In case of multiple
@Configuration
classes, later@Bean
definitions will override ones defined in earlier loaded files. This can be leveraged to deliberately override certain bean definitions via an extra Configuration class.- Since:

Method Detail
setBeanNameGenerator
public void setBeanNameGenerator(BeanNameGenerator beanNameGenerator)
Set a customBeanNameGenerator
for use withAnnotatedBeanDefinitionReader
and/orClassPathBeanDefinitionScanner
.Default is
AnnotationBeanNameGenerator
.
getBeanNameGenerator
protected BeanNameGenerator getBeanNameGenerator()
Return the customBeanNameGenerator
for use withAnnotatedBeanDefinitionReader
and/orClassPathBeanDefinitionScanner
, if any.
setScopeMetadataResolver
public void setScopeMetadataResolver(ScopeMetadataResolver scopeMetadataResolver)
Set a customScopeMetadataResolver
for use withAnnotatedBeanDefinitionReader
and/orClassPathBeanDefinitionScanner
.Default is an
AnnotationScopeMetadataResolver
.
getScopeMetadataResolver
protected ScopeMetadataResolver getScopeMetadataResolver()
Return the customScopeMetadataResolver

, if any.
register
public void register(Class<?>... annotatedClasses)
Register one or more annotated classes to be processed.Note that
AbstractApplicationContext.refresh()
must be called in order for the context to fully process the new classes.- Specified by:
register
in interfaceAnnotationConfigRegistry
- Parameters:
annotatedClasses
- one or more annotated classes, e.g.@Configuration
classes- See Also:
scan(String...)
,loadBeanDefinitions(DefaultListableBeanFactory)
,AbstractRefreshableConfigApplicationContext.setConfigLocation(String)
,AbstractApplicationContext.refresh()
scan
public void scan(String... basePackages)
Perform a scan within the specified base packages.Note that
AbstractApplicationContext.refresh()
must be called in order for the context to fully process the new classes.- Specified by:
scan
in interfaceAnnotationConfigRegistry
- Parameters:
basePackages
- the packages to check for annotated classes- See Also:
loadBeanDefinitions(DefaultListableBeanFactory)
,register(Class...)
,AbstractRefreshableConfigApplicationContext.setConfigLocation(String)
,AbstractApplicationContext.refresh()
loadBeanDefinitions
protected void loadBeanDefinitions(DefaultListableBeanFactory beanFactory)
Register aBeanDefinition
for any classes specified byregister(Class...)
and scan any packages specified byscan(String...)
.For any values specified by
AbstractRefreshableConfigApplicationContext.setConfigLocation(String)
orAbstractRefreshableConfigApplicationContext.setConfigLocations(String[])
, attempt first to load each location as a class, registering aBeanDefinition
if class loading is successful, and if class loading fails (i.e. aClassNotFoundException
is raised), assume the value is a package and attempt to scan it for annotated classes.Enables the default set of annotation configuration post processors, such that
@Autowired
,@Required
, and associated annotations can be used.Configuration class bean definitions are registered with generated bean definition names unless the
value
attribute is provided to the stereotype annotation.- Specified by:
loadBeanDefinitions

beanFactory
- the bean factory to load bean definitions into- See Also:
