Examples of org.springframework.web.context.support.AnnotationConfigWebApplicationContext

org.springframework.web.context.support.AnnotationConfigWebApplicationContext
{@link org.springframework.web.context.WebApplicationContext WebApplicationContext}implementation which accepts annotated classes as input - in particular {@link org.springframework.context.annotation.Configuration @Configuration}-annotated classes, but also plain {@link org.springframework.stereotype.Component @Component}classes and JSR-330 compliant classes using {@code javax.inject} annotations. Allowsfor 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 {@link org.springframework.context.annotation.AnnotationConfigApplicationContext AnnotationConfigApplicationContext} for a web environment.
To make use of this application context, the {@linkplain ContextLoader#CONTEXT_CLASS_PARAM "contextClass"} context-param forContextLoader 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 {@code DispatcherServlet} or {@code ContextLoaderListener} when using thenew {@link org.springframework.web.WebApplicationInitializer WebApplicationInitializer}code-based alternative to {@code web.xml}. See its Javadoc for details and usage examples.
Unlike {@link XmlWebApplicationContext}, no default configuration class locations are assumed. Rather, it is a requirement to set the {@linkplain ContextLoader#CONFIG_LOCATION_PARAM "contextConfigLocation"}context-param for {@link ContextLoader} and/or "contextConfigLocation" init-param forFrameworkServlet. The param-value may contain both fully-qualified class names and base packages to scan for components. See {@link #loadBeanDefinitions}for exact details on how these locations are processed.
As an alternative to setting the "contextConfigLocation" parameter, users may implement an {@link org.springframework.context.ApplicationContextInitializer ApplicationContextInitializer} and set the{@linkplain ContextLoader#CONTEXT_INITIALIZER_CLASSES_PARAM "contextInitializerClasses"}context-param / init-param. In such cases, users should favor the {@link #refresh()}and {@link #scan(String)} methods over the {@link #setConfigLocation(String)}method, which is primarily for use by {@code ContextLoader}
Note: In case of multiple {@code @Configuration} classes, later {@code @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. @author Chris Beams @author Juergen Hoeller @since 3.0 @see org.springframework.context.annotation.AnnotationConfigApplicationContext
