public class AnnotationConfigWebApplicationContext extends AbstractRefreshableWebApplicationContext
WebApplicationContext
implementation which accepts annotated classes as input - in particular
@Configuration-annotated
classes, but also plain @Component
classes 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.
As of Spring 3.1, this class may also be directly instantiated and injected into
Spring's DispatcherServlet or ContextLoaderListener when using the
new WebApplicationInitializer
code-based alternative to web.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 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. See loadBeanDefinitions(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 the AbstractApplicationContext.refresh()
and scan(String...) methods over the setConfigLocation(String)
method, which is primarily for use by ContextLoader
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 void setConfigLocation(String location)
If not set, the implementation may use a default as appropriate.
This implementation accepts delimited values in the form of fully-qualified
class names, (typically of Configuration classes) or fully-qualified
packages to scan for annotated classes. During loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory), these
locations will be processed in their given order, first attempting to load each
value as a class. If class loading fails (i.e. a ClassNotFoundException
occurs), the value is assumed to be a package and scanning is attempted.
Note that this method exists primarily for compatibility with Spring's
ContextLoader and that if this application
context is being configured through an
ApplicationContextInitializer, use of the
register(java.lang.Class<?>...) and scan(java.lang.String...) methods are preferred.

If not set, the implementation may use a default as appropriate.
This implementation accepts individual location values as fully-qualified class
names (typically @Configuration classes) or fully-qualified packages to
scan. During loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory), these locations will be processed in
order, first attempting to load values as a class, and upon class loading failure
the value is assumed to be a package to be scanned.

AbstractApplicationContext.refresh() must be called in order for the context to fully

Calls to register(java.lang.Class<?>...) are idempotent; adding the same
annotated class more than once has no additional effect.

BeanDefinition for

specified by scan(String...).
For any values specified by setConfigLocation(String) or
setConfigLocations(String[]), attempt first to load each location as a
class, registering a BeanDefinition if class loading is successful,
and if class loading fails (i.e. a ClassNotFoundException 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.
