Class AbstractAnnotationConfigDispatcherServletInitializer
- java.lang.Object
- org.springframework.web.context.AbstractContextLoaderInitializer
- org.springframework.web.servlet.support.AbstractDispatcherServletInitializer
- org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer
- All Implemented Interfaces:
WebApplicationInitializer
public abstract class AbstractAnnotationConfigDispatcherServletInitializer extends AbstractDispatcherServletInitializer
WebApplicationInitializer
to register aDispatcherServlet
and use Java-based Spring configuration.Implementations are required to implement:
getRootConfigClasses()
-- for "root" application context (non-web infrastructure) configuration.getServletConfigClasses()
-- forDispatcherServlet
application context (Spring MVC infrastructure) configuration.
If an application context hierarchy is not required, applications may return all configuration via
getRootConfigClasses()
and returnnull
fromgetServletConfigClasses()

Method Detail
createRootApplicationContext
@Nullable protected WebApplicationContext createRootApplicationContext()
Create the "root" application context to be provided to theContextLoaderListener
.The returned context is delegated to
ContextLoaderListener(WebApplicationContext)
and will be established as the parent context for anyDispatcherServlet
application contexts. As such, it typically contains middle-tier services, data sources, etc.This implementation creates an
AnnotationConfigWebApplicationContext
, providing it the annotated classes returned bygetRootConfigClasses()
. Returnsnull
ifgetRootConfigClasses()
returnsnull
.- Specified by:
createRootApplicationContext
in classAbstractContextLoaderInitializer
- Returns:
- the root application context, or
null
if a root context is not desired - See Also:
AbstractDispatcherServletInitializer
createServletApplicationContext
protected WebApplicationContext createServletApplicationContext()
Create a servlet application context to be provided to theDispatcherServlet
.The returned context is delegated to Spring's
DispatcherServlet(WebApplicationContext)
. As such, it typically contains controllers, view resolvers, locale resolvers, and other web-related beans.This implementation creates an
AnnotationConfigWebApplicationContext
, providing it the annotated classes returned bygetServletConfigClasses()
.
getRootConfigClasses
@Nullable protected abstract Class<?>[] getRootConfigClasses()
- Returns:
- the configuration for the root application context, or
null
if creation and registration of a root context is not desired
getServletConfigClasses
@Nullable protected abstract Class<?>[] getServletConfigClasses()
- Returns:
- the configuration for the Servlet application context, or
null
if all configuration is specified through root config classes.
