This commit updates the annotation processor and the binder to ignore
any static or abstract method that has the characteristics of a JavaBean
accessor. As a result, no property is generated for those (invalid)
accessor and no binding occurs on them either.
Closes gh-12390
Prior to this commit, all `WebMvcConfigurer` instances provided by user
configuration were processed *before* the one provided by the
`WebMvcAutoConfiguration`.
For many options this has no consequence, but for some, like the
`ContentNegotiationConfigurer`, settings were overriden by the
auto-configuration even if developers provided an opinion.
This commit orders the `WebMvcConfigurer` provided by the
auto-configuration at `0`, so that custom configurers (unordered, at
`Ordered.LOWEST_PRECEDENCE`) are processed *after*.
This still gives room to developers for configuring things *before* the
auto-configuration - they can still order their own configuration
accordingly.
Fixes gh-12389
This commit fixes the binder so that it property identifies JavaBean
accessors. Previously an accessor named `get` or `is` was identified.
Similarly, a setter named `set` was identified.

This commit defers the resolution of the default ddl auto mode only when
it is absolutely necessary. This prevents Spring Boot to attempt to get
a connection when it isn't necessary

Previously, when performing lazy initialisation of the context,
ApplicationContextRequestMatcher assigned the context field before it
called initialized. The context being non-null is used as the signal
that it’s ok to call a subclass’s matches method. If one thread checks
for a non-null context in between the field being assigned and
initialized being called on another thread, matches will be called
before the subclass is ready.
This commit closes the window for the race condition by only assigning
the context field once the subclass’s initialized method has been
called.
There is a secondary problem in each of the subclasses. Due to the use
of double-checked locking in ApplicationContextRequestMatcher, it’s
possible for a subclass’s matches method to be called by a thread that
has not synchronised on the context lock that’s held when initialized
is called and the delegate field is assigned. This means that the
value assigned to the field may not be visible to that thread.
This commit declares the delegate field of each
ApplicationContextRequestMatcher subclass as volatile to ensure that,
following initialisation, its value is guaranteed to be visible to
all threads.
Closes gh-12380
This commit detects if a `ConnectionNameStrategy` bean exists in the
context and associates it with the auto-configured RabbitMQ's
`ConnectionFactory` when that is the case.
