public class AnnotationConfigServletWebApplicationContext extends org.springframework.web.context.support.GenericWebApplicationContext implements org.springframework.context.annotation.AnnotationConfigRegistry
GenericWebApplicationContextthat 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).

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 through an extra Configuration class.

Since:
2.2.0

      public void setEnvironment(org.springframework.core.env.ConfigurableEnvironment environment)

      Delegates given environment to underlying AnnotatedBeanDefinitionReader and ClassPathBeanDefinitionScanner members.

      Specified by:

      Overrides:
      setEnvironment in class org.springframework.context.support.AbstractApplicationContext

      Provide a custom BeanNameGenerator for use with AnnotatedBeanDefinitionReader and/or ClassPathBeanDefinitionScanner, if any.

      Default is AnnotationBeanNameGenerator.

      Parameters:
      beanNameGenerator - the bean name generator
      See Also:
      • AnnotatedBeanDefinitionReader.setBeanNameGenerator(org.springframework.beans.factory.support.BeanNameGenerator)

      Any call to this method must occur prior to calls to register(Class...) and/or scan(String...).

      Parameters:
      scopeMetadataResolver - the scope metadata resolver

    • register

      public final void register(Class<?>... annotatedClasses)
