This is quite a big step, but I think it helps a lot. Since Spring
Boot always creates an AuthenticationManager if it doesn't find one
already registered, it makes sense to also make it into a @Bean.
Spring Security does not register its AuthenticationManager by
default though, so we have to do that for it if the user has created
one with an @Autowired AuthenticationManagerBuilder, but not registered
it as a @Bean.
Having the @Bean (marked @Primary to prevent issues with @Autowired)
makes it easier to reason about what Spring Boot has done for you, and
easier to default in simple use cases to the boot-created
AuthenticationManager. For example, if I want an OAuth2 Authorization
Server with password grant, it makes total sense for the
AuthenticationManager for users to be the same as the @Primary one.
Now it is easy to set that up (just @Autowire it).
...bean with no explicit @Bean DispatcherServlet. We still have to check
by bean name (slightly unfortunate, but we need to avoid instantiating
too early) so there's now another magic
bean name for the registration bean ("dispatcherServletRegistration")
that the user has to replace if he wants the registration without
defining a servlet @Bean

Rename ConfigurableEmbeddedServletContainerFactory to
ConfigurableEmbeddedServletContainer and extract
AbstractConfigurableEmbeddedServletContainer from
AbstractEmbeddedServletContainerFactory.
There's no explicit support for older Servlet specs in Spring Boot,
but we can at least make it easy for others to provide such
support by not adding stuff to the context when in an older container.
Some assumptions were being made in tests, e.g. about
there being an AuthenticationManager @Bean, which were
false with the new Security 3.2.1 updates from Rob.
Also parent-child contexts with the actuator were
problematic because they didn't exclude the web configuration
for the management security in the parent context.
Fixes gh-244
Also change strategy for defaulting of Authentication. Spring
Boot authentication defaults are now encapsulated and can easily
be overridden by a user defined AuthenticationManager.
The existing behaviour of JobLauncherCommandLineRunner was really too
basic. It has now been enhanced (at the expense of duplicating a lot
of code in Spring Batch it seems) to automatically increment job
parameters if it can, and to retry a failed or stopped execution
if it can (without incrementing, but with additional job parameters
added from command line if they are non-identifying).
The JobLauncherCommandLineRunner is more extendable and exposes
its DI wiring points now as well, so hopefully users can make
use of it independently of autoconfig (by providing a @Bean of
that type).
Not everything from the wishlist in gh-325 is implememented yet,
but it should be a good platform to work with and to extend.
Better even than logging would be to fail fast? Surely it's a
mistake not to have any /templates if Thymeleaf is in use.
User can disable failfast by exlcuding thymeleaf configuration
or by providing their own ITemplateResolver.
Fixes gh-294
User can switch the behaviour on and off with
spring.datasource.continueOnError:true|false. I decided
not to add an extra nested level of property resolution
because of the existing spring.datasource.schema
(and other properties relating to initialization) because
concision seemed like a good thing with those more common
settings.
Fixes gh-374
The DispatcherServletAutoConfiguration had a condition on it that
meant it wasn't used at all if there was no EmbeddedServletContainerFactory.
It's amazing that any WAR ever deployed.
Also added some info logging to servlet and filter registrations.
Update OnBeanCondition to attempt to consider FactoryBean classes
for bean type matches. To ensure early instantiation does not occur, the
object type from the FactoryBean is deduced by resolving generics on the
declaration.
Fixes gh-355
Update AbstractRepositoryConfigurationSourceSupport to use the newly
introduced RepositoryConfigurationDelegate instead of effectively
reimplementing Spring Data Commons functionality which was prone to
changes in the API (code that wasn't considered to be API in the first
place).
Switch from implementing BeanClassLoaderAware to ResourceLoaderAware
to avoid having to set up a DefaultResourceLoader which should also
improve IDE integration.
Fixes gh-236
