public class AnnotationConfigApplicationContext extends GenericApplicationContext implements AnnotationConfigRegistry
Standalone application context, accepting component classes as input — in particular@Configuration
-annotated classes, but also plain@Component
types and JSR-330 compliant classes usingjavax.inject
annotations.Allows for registering classes one by one using
register(Class...)
as well as for classpath scanning usingscan(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.- 从以下版本开始:

构造器详细资料
AnnotationConfigApplicationContext
public AnnotationConfigApplicationContext()
Create a new AnnotationConfigApplicationContext that needs to be populated throughregister(java.lang.Class<?>...)
calls and then manually refreshed.
AnnotationConfigApplicationContext
public AnnotationConfigApplicationContext(DefaultListableBeanFactory beanFactory)
Create a new AnnotationConfigApplicationContext with the given DefaultListableBeanFactory.- 参数:
beanFactory
- the DefaultListableBeanFactory instance to use for this context
AnnotationConfigApplicationContext
public AnnotationConfigApplicationContext(Class<?>... componentClasses)
Create a new AnnotationConfigApplicationContext, deriving bean definitions from the given component classes and automatically refreshing the context.- 参数:
componentClasses
- one or more component classes — for example,@Configuration
classes
AnnotationConfigApplicationContext
public AnnotationConfigApplicationContext(String... basePackages)
Create a new AnnotationConfigApplicationContext, scanning for components in the given packages, registering bean definitions for those components, and automatically refreshing the context.- 参数:
basePackages
- the packages to scan for component classes

setEnvironment
public void setEnvironment(ConfigurableEnvironment environment)
Propagate the given customEnvironment
to the underlyingAnnotatedBeanDefinitionReader
andClassPathBeanDefinitionScanner
.- 指定者:
setEnvironment
在接口中ConfigurableApplicationContext
- 覆盖:
setEnvironment
在类中AbstractApplicationContext
- 参数:
environment
- the new environment- 另请参阅:
AbstractApplicationContext.createEnvironment()
setBeanNameGenerator
public void setBeanNameGenerator(BeanNameGenerator beanNameGenerator)
Provide a customBeanNameGenerator
for use withAnnotatedBeanDefinitionReader
and/orClassPathBeanDefinitionScanner
, if any.Default is
AnnotationBeanNameGenerator
.Any call to this method must occur prior to calls to
register(Class...)
and/orscan(String...)
.- 另请参阅:
