public class AnnotationConfigApplicationContext
extends GenericApplicationContext
implements AnnotationConfigRegistry
```
Standalone application context, accepting annotated classes as input - in particular @Configuration-annotated classes, but also plain @Component types and JSR-330 compliant classes using javax.inject annotations. Allows for registering classes one by one using register(Class...) as well as for classpath scanning using scan(String...).
In case of multiple @Configuration classes, @Bean methods defined in later classes will override those defined in earlier classes. This can be leveraged to deliberately override certain bean definitions via an extra @Configuration class.
See @Configuration's javadoc for usage examples.

```
public AnnotationConfigApplicationContext()
```
    Create a new AnnotationConfigApplicationContext that needs to be populated through register(java.lang.Class<?>...) calls and then manually refreshed.
  - AnnotationConfigApplicationContext
```
public AnnotationConfigApplicationContext(DefaultListableBeanFactory beanFactory)
```
    Create a new AnnotationConfigApplicationContext with the given DefaultListableBeanFactory.
    Parameters:
    beanFactory - the DefaultListableBeanFactory instance to use for this context
  - AnnotationConfigApplicationContext
```
public AnnotationConfigApplicationContext(Class<?>... annotatedClasses)
```
    Create a new AnnotationConfigApplicationContext, deriving bean definitions from the given annotated classes and automatically refreshing the context.
    Parameters:
    annotatedClasses - one or more annotated classes, e.g. @Configuration classes
  - AnnotationConfigApplicationContext
```
public AnnotationConfigApplicationContext(String... basePackages)
```
    Create a new AnnotationConfigApplicationContext, scanning for bean definitions in the given packages and automatically refreshing the context.
    Parameters:
    basePackages - the packages to check for annotated classes
- Method Detail
  - setEnvironment
```
public void setEnvironment(ConfigurableEnvironment environment)
```
    Propagates the given custom Environment to the underlying AnnotatedBeanDefinitionReader and ClassPathBeanDefinitionScanner.
    Specified by:
    setEnvironment in interface ConfigurableApplicationContext
    Overrides:
    setEnvironment in class AbstractApplicationContext
    Parameters:
    environment - the new environment
    See Also:
    AbstractApplicationContext.createEnvironment()
  - setBeanNameGenerator
```
public void setBeanNameGenerator(BeanNameGenerator beanNameGenerator)
```
    Provide a custom BeanNameGenerator for use with AnnotatedBeanDefinitionReader and/or ClassPathBeanDefinitionScanner, if any.
    Default is AnnotationBeanNameGenerator.
    Any call to this method must occur prior to calls to register(Class...) and/or scan(String...).
    See Also:
    AnnotatedBeanDefinitionReader.setBeanNameGenerator(org.springframework.beans.factory.support.BeanNameGenerator), ClassPathBeanDefinitionScanner.setBeanNameGenerator(org.springframework.beans.factory.support.BeanNameGenerator)
  - setScopeMetadataResolver
```
public void setScopeMetadataResolver(ScopeMetadataResolver scopeMetadataResolver)
```
    Set the ScopeMetadataResolver to use for detected bean classes.
