- 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
```
Base class for WebApplicationInitializer implementations that register a DispatcherServlet configured with annotated classes, e.g. Spring's @Configuration classes.
Concrete implementations are required to implement getRootConfigClasses() and getServletConfigClasses() as well as AbstractDispatcherServletInitializer.getServletMappings(). Further template and customization methods are provided by AbstractDispatcherServletInitializer.
This is the preferred approach for applications that use Java-based Spring configuration.

public AbstractAnnotationConfigDispatcherServletInitializer()
```
- Method Detail
  - createRootApplicationContext
```
protected WebApplicationContext createRootApplicationContext()
```
    Create the "root" application context to be provided to the ContextLoaderListener.
    The returned context is delegated to ContextLoaderListener(WebApplicationContext) and will be established as the parent context for any DispatcherServlet application contexts. As such, it typically contains middle-tier services, data sources, etc.
    This implementation creates an AnnotationConfigWebApplicationContext, providing it the annotated classes returned by getRootConfigClasses(). Returns null if getRootConfigClasses() returns null.
    Specified by:
    createRootApplicationContext in class AbstractContextLoaderInitializer
    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 the DispatcherServlet.
    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 by getServletConfigClasses().
    Specified by:
    createServletApplicationContext in class AbstractDispatcherServletInitializer
    See Also:
    AbstractDispatcherServletInitializer.registerDispatcherServlet(ServletContext)
  - getRootConfigClasses
```
protected abstract Class<?>[] getRootConfigClasses()
```
    Specify @Configuration and/or @Component classes to be provided to the root application context.
    Returns:
    the configuration classes for the root application context, or null if creation and registration of a root context is not desired
  - getServletConfigClasses
```
protected abstract Class<?>[] getServletConfigClasses()
```
    Specify @Configuration and/or @Component classes to be provided to the dispatcher servlet application context.
    Returns:
    the configuration classes for the dispatcher servlet application context or null if all configuration is specified through root config classes.
