public class AnnotationConfigWebApplicationContext
extends AbstractRefreshableWebApplicationContext

WebApplicationContext implementation which accepts annotated classes as input - in particular @Configuration-annotated classes, but also plain @Components and JSR-330 compliant classes using javax.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.

Unlike XmlWebApplicationContext, no default configuration class locations are assumed. Rather, it is a requirement to set the "contextConfigLocation" context-param for ContextLoader and/or "contextConfigLocation" init-param for FrameworkServlet. The param-value may contain both fully-qualified class names and base packages to scan for components.

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.

public AnnotationConfigWebApplicationContext()
Method Detail

loadBeanDefinitions

protected void loadBeanDefinitions(DefaultListableBeanFactory beanFactory)
Register a BeanDefinition for each class specified by AbstractRefreshableWebApplicationContext.getConfigLocations(), or scan each specified package 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 in class AbstractRefreshableApplicationContext
Parameters:
beanFactory - the bean factory to load bean definitions into

getBeanNameGenerator

protected BeanNameGenerator getBeanNameGenerator()
Provide a custom BeanNameGenerator for use with AnnotatedBeanDefinitionReader and/or ClassPathBeanDefinitionScanner, if any.

Default is AnnotationBeanNameGenerator.

See Also:
AnnotatedBeanDefinitionReader.setBeanNameGenerator(org.springframework.beans.factory.support.BeanNameGenerator), ClassPathBeanDefinitionScanner.setBeanNameGenerator(org.springframework.beans.factory.support.BeanNameGenerator)

getScopeMetadataResolver

protected ScopeMetadataResolver getScopeMetadataResolver()
Provide a custom ScopeMetadataResolver for use with AnnotatedBeanDefinitionReader and/or ClassPathBeanDefinitionScanner, if any.

Default is AnnotationScopeMetadataResolver.

See Also:
AnnotatedBeanDefinitionReader.setScopeMetadataResolver(org.springframework.context.annotation.ScopeMetadataResolver), ClassPathBeanDefinitionScanner.setScopeMetadataResolver(org.springframework.context.annotation.ScopeMetadataResolver)
