When a header is being set, verify that the type that's provided is
legal for the header that's been set. For example, the error channel's
type must be a MessageChannel or a String.
The method that performs type verification is protected so that it
can be overriden by sub-classes. It is expected that an overriding
method will call the super method.
A new type MessageHeaderAccesssor provides read/write access to
MessageHeaders along with typed getter/setter methods along the lines
of the existing MessageBuilder methods (internally MessageBuilder
merely delegates to MessageHeaderAccessor). This class is extensible
with sub-classes expected to provide typed getter/setter methods for
specific categories of message headers.
NativeMessageHeaderAccessor is one specific sub-class that further
provides read/write access to headers from some external message
source (e.g. STOMP headers). Native headers are stored in a separate
MultiValueMap and kept under a specific key.
Update MethodValidationPostProcessor.setValidator(...) to use
LocalValidatorFactoryBean.getValidator() when possible.
This is required because LocalValidatorFactoryBean does not directly
implement the forExecutables() method introduced in bean validation v1.1.

Allow the @CachePut 'key' SpEL to refer to the result of the method call
via a '#result' variable.
This change is particularly useful when working with JPA entities that
have generated @Id values since the ID will often not be available
until the entity has been saved.
Issue: SPR-10664
Introduce new SimpleKeyGenerator class to supersede DefaultKeyGenerator.
Unlike DefaultKeyGenerator, no collisions will occur with the keys
generated by SimpleKeyGenerator as the full parameter values are
considered within the SimpleKey.equals(...) method.
The SimpleKeyGenerator is now the default class used when no explicit
generator is configured.
Issue: SPR-10237
Add EnhancedConfigurationBeanPostProcessor to inject the BeanFactory
into EnhancedConfiguration classes before the
AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues method
is called.
Prior to this commit it was possible for @Autowire in a @Configuration
class to invoke an enhanced configuration class method before the
BeanFactory was injected. This is due to the fact that the
AutowiredAnnotationBeanPostProcessor was called before
AbstractAutowireCapableBeanFactory.invokeAwareMethods().
Issue: SPR-10668
Rename to PubSubHeaderAccessor and StompHeaderAccessor
Move the renamed classes to support packages
Remove fromPayloadAndHeaders from MessageBuilder, just use
withPayload(..).copyHeaders(..) instead.
To improve compatibility between Spring's messaging classes and
Spring Integration, the type of Message that is created has been made
pluggable through the introduction of a factory abstraction;
MessageFactory.
By default a MessageFactory is provided that will create
org.springframework.messaging.GenericMessage instances, however this
can be replaced with an alternative implementation. For example,
Spring Integration can provide an implementation that creates
org.springframework.integration.message.GenericMessage instances.
This control over the type of Message that's created allows messages
to flow from Spring messaging code into Spring Integration code without
any need for conversion. In further support of this goal,
MessageChannel, MessageHandler, and SubscribableChannel have been
genericized to make the Message type that they deal with more
flexible.
Introduce new ConfigurationCondition interface allowing more
fine-grained control for @Conditional when used with @Configuration
beans.
Primarily added so that the evaluation of conditions that inspect bean
definitions can be deferred until all @Configuration classes have been
parsed.
Issue: SPR-10534
Update ConfigurationClassParser to fall-back to ASM parsing if standard
annotation processing fails. This change allows @Conditional annotations
that refer to missing classes to work.
This commit also introduces a new inner SourceClass object that
encapsulates the conditional logic required when reading the source
classes.
Issue: SPR-10646
Defer @Conditional processing on @Configuration classes until the bean
definitions are loaded, rather than when the @Configuration class is
parsed. This provides better support for @Conditional implementations
that inspect bean definitions.
This commit also fixes some minor problems with original implementation
and replaces the ConditionalAnnotationHelper class with
ConditionEvaluator.
Issue: SPR-10534
Update ConfigurationClassUtils to only consider beans with @Bean
methods as 'lite' configuration candidates.
Prior to this commit all @Component beans were considered 'lite'
configuration candidates which could result in a large number of
ConfigurationClass instance being created that would ultimately be
ignored.
Issue: SPR-10609
Refactor ConfigurationClassEnhancer so that BeanFactory instances are
not held against CGLIB Callback objects. Enhanced @Configuration classes
now use the BeanFactoryAware interface in order to obtain a BeanFactory.
This change has the additional benefit that a static final field can
now be used to hold all Callback instances.
Issue: SPR-10307
Introduce new @Conditional annotation that can be used to filter
which @Configuration classes or methods are loaded. @Conditional
can be used directly or as a meta-annotation. Condition implementations
are provided via the 'Condition' interface and are free to filter based
on any criteria available at the time that they run. The
ConditionalContext provides access to the BeanDefinitionRegistry,
Environment and ConfigurableListableBeanFactory along with a
ResourceLoader and ClassLoader.
The existing @Profile annotation has been refactored as a @Conditional
with the added benefit that it can now be used as a method level
annotation.
Add PropertySourcesPlaceholderConfigurer.getAppliedPropertySources() to
allow access to the PropertySources that were actually applied.
Issue: SPR-10545
Allow classes that are annotated with @Import to be considered as 'lite'
@Configuration candidates. Allows the AnnotationConfigApplicationContext
to directly register @Import beans even if they are not @Components.
Issue: SPR-10533
Implementations of Spring's ImportSelector interface may
now implement any of the following *Aware interfaces and have their
respective methods called prior to #registerBeanDefinitions:
- BeanFactoryAware
- BeanClassLoaderAware
- ResourceLoaderAware
Issue: SPR-10530
This allows for restoring a static MessageSourceResourceBundleLocator implementation, just implementing the interface at the new spi location introduced in HV 4.3 and preserved in 5.0.
