public class AnnotationConfigServletWebServerApplicationContext
extends ServletWebServerApplicationContext
implements AnnotationConfigRegistry

ServletWebServerApplicationContext that 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:

1.0.0

Constructor Details

AnnotationConfigServletWebServerApplicationContext

public AnnotationConfigServletWebServerApplicationContext()

Create a new AnnotationConfigServletWebServerApplicationContext that needs to be populated through register(java.lang.Class<?>...) calls and then manually refreshed.

AnnotationConfigServletWebServerApplicationContext

public AnnotationConfigServletWebServerApplicationContext(DefaultListableBeanFactory beanFactory)

Create a new AnnotationConfigServletWebServerApplicationContext with the given DefaultListableBeanFactory. The context needs to be populated through register(java.lang.Class<?>...) calls and then manually refreshed.

Parameters:

beanFactory - the DefaultListableBeanFactory instance to use for this context

AnnotationConfigServletWebServerApplicationContext

public AnnotationConfigServletWebServerApplicationContext(Class<?>... annotatedClasses)

Create a new AnnotationConfigServletWebServerApplicationContext, deriving bean definitions from the given annotated classes and automatically refreshing the context.

Parameters:

annotatedClasses - one or more annotated classes, e.g. @Configuration classes

AnnotationConfigServletWebServerApplicationContext

public AnnotationConfigServletWebServerApplicationContext(String... basePackages)

Create a new AnnotationConfigServletWebServerApplicationContext, scanning for bean definitions in the given packages and automatically refreshing the context.

Parameters:

basePackages - the packages to check for annotated classes

Method Details

setEnvironment

public void setEnvironment(ConfigurableEnvironment environment)

Delegates given environment to underlying AnnotatedBeanDefinitionReader and ClassPathBeanDefinitionScanner members.

Specified by:

setEnvironment in interface ConfigurableApplicationContext

Overrides:

setEnvironment in class AbstractApplicationContext

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...).

Parameters:

beanNameGenerator - the bean name generator

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.

The default is an AnnotationScopeMetadataResolver.

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)

Register one or more annotated classes to be processed. Note that ServletWebServerApplicationContext.refresh() must be called in order for the context to fully process the new class.

Calls to #register are idempotent; adding the same annotated class more than once has no additional effect.

Specified by:

register in interface AnnotationConfigRegistry

Parameters:

annotatedClasses - one or more annotated classes, e.g. @Configuration classes

See Also:

• scan(String...)
• ServletWebServerApplicationContext.refresh()

scan

public final void scan(String... basePackages)

Perform a scan within the specified base packages. Note that ServletWebServerApplicationContext.refresh() must be called in order for the context to fully process the new class.

Specified by:

scan in interface AnnotationConfigRegistry

Parameters:

basePackages - the packages to check for annotated classes

See Also:

• register(Class...)
• ServletWebServerApplicationContext.refresh()

prepareRefresh

protected void prepareRefresh()

Overrides:

prepareRefresh in class AbstractApplicationContext

postProcessBeanFactory

protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)

Description copied from class: ServletWebServerApplicationContext

Register ServletContextAwareProcessor.

Overrides:

postProcessBeanFactory in class ServletWebServerApplicationContext
