Touch up a few setter methods across the SessionFactoryBuilder
hierarchy that were still returning void.
Use varargs... syntax wherever possible.

Large refactoring of existing *SessionFactoryBean hierarchy designed to
support configuration of Hibernate SessionFactory objects within
@Configuration class @Bean methods without forcing use of a
FactoryBean type, which is generally discouraged due to awkwardness
of programming model and lifecycle issues. Refactored and new types
include:
* Removal of AbstractSessionFactoryBean, replacing it with
SessionFactoryBeanSupport abstract base class
* Introduction of SessionFactoryBuilder and
AnnotationSessionFactoryBuilder types, both direct subclasses of
SessionFactoryBuilderSupport. These types are intended for direct
use within @Bean methods. They expose method-chainable set*
methods allowing for concise and convenient use. See JavaDoc
on both types for usage examples.
* LocalSessionFactoryBean and AnnotationSessionFactoryBean types are
now subclasses, respectively, of the *Builder types above.
LSFB and ASFB backward-compatibility has been maintained almost
entirely. The one exception is that there is no longer a protected
convertHibernateAccessException() method available in the hierarchy.
This method was not likely often used anyway and has been replaced
by the new (and public) setPersistenceExceptionTranslator() which
accepts instances of type HibernateExceptionTranslator as introduced in
SPR-8076.
LSFB and ASFB setter method signatures have changed. They no longer
return void in standard JavaBeans style but rather, and due to extending
the *Builder types above, return the 'this' reference. This posed a
problem because the Spring container has to date been unable to detect
and provide dependency injection against non-void returning setter
methods. This limitation was due to the way that the default JavaBeans
Introspector class and its getBeanInfo() method works, and prompted the
introduction and intergration of ExtendedBeanInfo, already completed in
SPR-8079. So have no concern if you notice this signature change - it
all works.
Certain deprecations have been made:
* All LSFB/ASFB methods related to Hibernate's CacheProvider SPI,
reflecting its deprecation in Hibernate 3.3 in favor of the new
RegionFactory SPI. Note these methods have been preserved only
on the FactoryBean types. The new *SessionFactoryBuilder
supertypes do not expose CacheProvider services at all.
* All protected LSFB/ASFB methods that accept a Hibernate
Configuration parameter, such as newSessionFactory(Configuration),
postProcessMappings(Configuration) and
postProcessConfiguration(Configuation), in favor of no-arg methods
with the same names. Due to the nature of the hierarchy
refactoring mentioned above, the Configuration instance is always
available when these methods are called, thus no need to pass it
in as a parameter.
In the process, our approach to automatic detection of Hibernate dialect
has been improved (it was in fact broken before). Thanks to James
Roper for his suggestion in SPR-7936 as to how to fix this.
See HibernateSessionFactoryConfigurationTests as a starting point for
understanding the new builder-style approach to SessionFactory creation.
Note especially use of the SessionFactoryBuilder#doWithConfiguration
method which allows for direct programmatic configuration of the Native
Hibernate (Annotation)Configuration API.
As a final note, AnnotationConfiguration has been deprecated in
Hibernate 3.6, and great pains have been taken to ensure that users
of any supported Hibernate version (3.2 -> 3.6) will never need to
(a) cast from Configuration to AnnotationConfiguration or (b)
experience deprecation warnings due to being forced to use the
AnnotationConfiguration API. Explore the JavaDoc around the
doWithConfiguration() method and HibernateConfigurationCallback type
for complete details.

Designed to allow persistence exception translation of
HibernateException types without being forced to use
LocalSessionFactoryBean types.
Committed now in support of the forthcoming introduction of
*SessionFactoryBuilder types.
Issue: SPR-8076
git-svn-id: https://src.springframework.org/svn/spring-framework/trunk@4145 50f2f4bb-b051-0410-bef5-90022cba6387
Decorator for instances returned from
Introspector#getBeanInfo(Class<?>) that supports detection and inclusion
of non-void returning setter methods. Fully supports indexed properties
and otherwise faithfully mimics the default
BeanInfo#getPropertyDescriptors() behavior, e.g., PropertyDescriptor
ordering, etc.
This decorator has been integrated with CachedIntrospectionResults
meaning that, in simple terms, the Spring container now supports
injection of setter methods having any return type.

Previously errors were being raised when trying to inject @Value
annotated paramaters such as:
@Feature
public FeatureSpec feature(@Value("#{environment['foo']}") String foo) {
return new FeatureSpec(foo);
}
This is not so much because dependency resolution of @Value-annotated
types was failing, but rather because the 'early bean reference'
proxying mechanism was throwing an exception if any final type was
detected as a parameter. This is of course because final types are
non-subclassable by CGLIB. On review, however, it's obvious that
certain final types must be allowed for injection. @Value injection
is an obvious one, but the rarer case of a Spring bean of type String
or int is another.
The explicit guard against final types as parameters to @Feature methods
has been removed. Final types are still checked for, however, and if
found, no proxing is attempted. The dependency is immediately resolved
against the current BeanFactory and injected into the @Feature method.
This means that @Value injection, @Qualifier injection, etc all work
as expected, but does mean that premature bean instantiation may occur
if a user unwittingly injects non-String, non-primitive final bean types
as @Feature method parameters.

CGLIB-enhanced @Configuration subclasses now implement DisposableBean
such that Enhancer.registerStaticCallbacks(subclass, null) is invoked
on container shutdown. This ensures that garbage collection can work
properly and avoids memory consumption issues for applications that
create and destroy many application contexts within the same JVM.

Prove that injection of special container types such as ResourceLoader,
BeanFactory, etc already works with the current implementation of
@Feature methods.

Previously, only commas could delimit <beans profile="p1,p2"/>. Now, as
with <bean alias="..."/>, the profile attribute allows for delimiting
by comma, space and/or semicolon.
BeanDefinitionParserDelegate.MULTI_VALUE_ATTRIBUTE_DELIMITERS has been
added as a constant to reflect the fact this set of delimiters is used
in multiple locations throughout the framework.
BDPD.BEAN_NAME_DELIMITERS now refers to the above and has been has been
preserved but deprecated for backward compat (though use outside the
framework is unlikely).
