Prior to this commit, some exceptions handled at the controller or
handler function level would:
* not bubble up to the Spring Boot error handling support
* not be tagged as part of the request metrics
This situation is inconsistent because in general, exceptions handled at
the controller level can be considered as expected behavior.
Also, depending on how the exception is handled, the request metrics
might not be tagged with the exception.
This will be reconsidered in gh-23795.
This commit prepares a transition to the new situation. Developers can
now opt-in and set the handled exception as a request attribute. This
well-known attribute will be later read by the metrics support and used
for tagging the request metrics with the exception provided.
This mechanism is automatically used by the error handling support in
Spring Boot.

Previously, the auto-configuration for DataSource initialization and
the properties used to configure it were part of the general
DataSource auto-configuration and properties.
This commit moves the auto-configuration of DataSource initialization
out into a separate top-level auto-configuration class. Similarly,
the properties for configuring DataSource initialization have been
moved from `spring.datasource.*` into `spring.sql.init.*`.
The old initialization-related `spring.datasource.*` properties have
been deprecated but can still be used. When they are used, they new,
separate initialization auto-configuration will back off. In other
words, the initialization related `spring.datasource.*` properties
and the `spring.sql.init.*` properties cannot be used in combination.

Polish the prefix support introduced in commit a8592f36d4 and fix a
package tangle between `boot.context.properties.source` and `boot.env`.
The `Prefix` interface has now been moved into a new default method on
`OriginLookup`.

This commit updates LoggingApplicationListener to register the logging
shutdown hook by default.
The hook is detrimental in a war deployment as it may pin parts of an
application in memory after it has been undeployed. For this reason,
the hook is still disabled by default in war deployments. This is
achieved by setting an attribute on the servlet context in
SpringBootServletInitializer that is then consumed via the Environment
by LoggingApplicationListener.
Closes gh-25046
We configure the `SystemEnvironmentPropertySource` as a `Prefixed` property
source. When adapting this to a `ConfigurationPropertySource, a
`PrefixedConfigurationPropertySource` will be created for it.
A `PrefixedConfigurationPropertySource` will resolve property
such as `foo.bar` to `my.foo.bar` for a prefix of `my`.
Closes gh-3450
Previously, DataSource initialization was triggered via a
BeanPostProcessor or a schema created event from JPA. This caused
numerous problems with circular dependencies, bean lifecycle, etc and
added significant complexity.
This commit reworks DataSource initialization to remove the use of a
BeanPostProcessor entirely. In its place, DataSource initialization is
now driven by an InitializingBean with dependency relationships
between beans ensuring that initialization has been performed before
the DataSource is used. This aligns with the approach that's worked
well with Flyway and Liquibase.
More changes are planned to further simplify DataSource initialization.
The changes in this commit are a foundation for those changes. Any new
public API in this commit is highly likely to change before the next
GA.

Currently Spring Integration creates its own `TaskScheduler` bean if one
does not exist in the context yet. When we add `@EnableScheduling`,
Spring Boot auto-configures one for us, but this one comes with slightly
different options than the default in Spring Integration.
This commit makes sure that Spring Integration reuses the
auto-configured TaskScheduler if possible, regardless of the user
opting-in for `@EnabledScheduling`.

Refine the package restructure started in 91ccc23462 to help provide
a solid foundation for code snippets. This commit renames many of the
classes so that they no longer end in `Example`. It also removes some
of the inner types that were previously used. Many tag comments have
also been moved to ensure that `import` statements are available in
the docs.
Closes gh-25089
Restructure the packages in `spring-boot-docs` so that they mirror
the documentation sections. There are now three main packages:
`springbootfeatures`, `productionreadyfeatures` and `howto`. Each
of the main packages has a subpackage named after the section headings.
Example code now uses consistent `// tag::` names and imports are
applied using `[tag=*]` whenever possible.
Test snippets have been moved to `src/main/java` so that only a single
import attribute needs to be defined.
Closes gh-25089
Update `build.gradle` files to ensure that `junit-platform-launcher` is
a `testRuntimeOnly` dependency. This ensures that tests can be run from
Eclipse.
