This commit and the several before it back out the
SessionFactoryBuilder and AnnotationSessionFactoryBuilder types
recently introduced in 3.1 M2. This is in light of the impending
release of Hibernate 4.0 GA and our own support for it the new
org.springframework.orm.hibernate4 package (not yet committed).
This new package will have a similar, but far simpler, arrangement of
a single LocalSessionFactoryBuilder and LocalSessionFactoryBean pair.
Hibernate 3.x support will remain largely as-is, however the
HibernateTransactionManager introduced with SPR-8076 will remain.
This reverts commit 9e8259198f07e495fd32359c0e0c197bb79a2ca0.

Prior to this change, @EnableTransactionManagement (via the
ProxyTransactionManagementConfiguration class) did not properly
register its auto-proxy creator through the usual AopConfigUtils
methods. It was trying to register the APC as a normal @Bean method,
but this causes issues (SPR-8494) with the logic in
AopConfigUtils#registerOrEscalateApcAsRequired, which expects the APC
bean definition to have a beanClassName property. When the APC is
registered via a @Bean definition, it is actually a
factoryBean/factoryMethod situation with no directly resolvable
beanClass/beanClassName.
To solve this problem, ImportSelector#selectImports has been refactored
to accept an ImportSelector.Context instance. This object contains the
AnnotationMetadata of the importing class as well as the enclosing
BeanDefinitionRegistry to allow for the kind of conditional bean
registration necessary here. In this case, the bean definition that
must be registered conditionally is that of the auto-proxy creator.
It should only be registered if AdviceMode == PROXY, and thus the
ImportSelector is an appropriate place to make this happen. It must
happen as a BeanDefinition (rather than a @Bean method) for
compatibility with AopConfigUtils, and working with the
BeanDefinitionRegistry API allows for that. This change does mean that
in certain cases like this one, #selectImports has container modifying
side effects. Documentation has been updated to reflect.

@PostConstruct added to ProxyTransactionManagementConfiguration cases
ConcurrentModificationException (as detailed previously in SPR-8397.
Backing out for now until a better solution can be devised.
This reverts commit 235b729514d125aef79fc3fae4bcfb1893642212.

Rather than trying to rework how AopConfigUtils works, a @PostConstruct
method has been added to ProxyTransactionManagementConfiguration to call
the usual AopConfigUtils registration methods.

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.

Branch in question is 'env' branch from git://git.springsource.org/sandbox/cbeams.git; merged into
git-svn repository with:
git merge -s recursive -Xtheirs --no-commit env
No merge conflicts, but did need to
git rm spring-build
prior to committing.
With this change, Spring 3.1.0 development is now happening on SVN
trunk. Further commits to the 3.0.x line will happen in an as-yet
uncreated SVN branch. 3.1.0 snapshots will be available
per the usual nightly CI build from trunk.
