Previously, the embedded database connection that would be used
could only be controlled via the classpath. If multiple embedded
database dependencies were present, it wasn't possible to control
the one that the auto-configured would use. It also wasn't possible
to disable auto-configuration of an embedded database.
This commit introduces a new configuration property,
spring.datasource.embedded-database-connection. It can be set to
one of the values of the EmbeddedDatabaseConnection enum to control
the auto-configuration of an embedded database. Setting it to none
will disable the auto-configuration and ensure that an external
database is used instead.

Rework the 'Supported Metrics' documentation to improve consistency
access subsections. Details about the `@Timer` annotation have been
pulled into a new section so that they can be referenced rather than
repeated.

This commit reworks the initial proposal so that jobs and triggers are
treated as first class concepts.
`/actuator/quartz` now returns the group names for jobs and triggers.
`actuator/quartz/jobs` returns the job names, keyed by the available
group names, while `/actuator/quartz/triggers` does the same for
triggers.
`/actuator/jobs/{groupName}` provides an overview of a job group. It
provides a map of job names with the class name of the job.
implementation
`/actuator/triggers/{groupName}` provides an overview of a trigger
group. There are five supported trigger implementations: cron, simple,
daily time interval, calendar interval, and custom for any other
implementation. Given that each implementation has specific settings,
triggers are split in five objects.
`/actuator/jobs/{groupName}/{jobName}` provides the full details of a
particular job. This includes a sanitized data map and a list of
triggers ordered by next fire time.
`/actuator/triggers/{groupName}/{triggerName}` provides the full details
of a particular trigger. This includes the state, its type, and a
dedicate object containing implementation-specific settings.

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.

This commit adds a customizer hook point for jOOQ's configuration. When
such a bean is present, it is invoked with the auto-configuration
`Configuration`. This effectively supersedes checking for a number of
jOOQ `*Provider`beans. The existing beans are still honoured, in a
deprecated fashion.
Closes gh-24732
This commit changes the default value of bootstrap-mode to "default"

Prior to this commit, packaging a Spring Boot application as a container
image with Cloud Native Buildpacks could result in unwanted browser
caching behavior, with "Last-Modified" HTTP response headers pointing to
dates in the far past.
This is due to CNB resetting the last-modified date metadata for static
files (for build reproducibility and container layer caching) and Spring
static resource handling relying on that information when serving static
resources.
This commit introduces a new configuration property
`spring.web.resources.cache.use-last-modified` that can be used to
disable this behavior in Spring if the application is meant to run as a
container image built by CNB.
The default value for this property remains `true` since this remains
the default value in Spring Framework and using that information in
other deployment models is a perfectly valid use case.

Previously, Quartz could be configured with a specific DataSource
using `@QuartzDataSource` but it was not possible to configure a
Quartz-specific transaction manager. This could result in the
different DataSources being used by Quartz itself and Quart'z
DataSourceTransactionManager.
This commit introduces a new qualifier, `@QuartzTransactionManager`,
that can be used to avoid the above-described problem. Any
`@QuartzTransactionManager`-annotated bean will be used by the
Quartz auto-configure configuration instead of the application's main
`TransactionManager`. If no such qualified bean is present, the
application's main TransactionManager, if any, will be used as before.
Fixes gh-20184
This commit removes `<version>` from the Maven Plugin documentation
where it makes sense so that versions aren't hardcoded unnecessarily.
Rather, a plugin or dependency management should be in place so those

Update `ConfigTreeConfigDataResource` so that a wildcard suffix can
be used to import multiple folders. The pattern logic from
`StandardConfigDataLocationResolver` has been extracted into a new

Previously, the base path of a servlet-based management server could be
configured using management.server.servlet.context-path but there was no
equivalent property for WebFlux.
This commit introduces a new property, management.server.base-path,
that can be used with both servlet and reactive management servers. The
existing servlet-specific property has been deprecated in favour of the
new general property. When using the servlet stack, if both the general
property and the servlet-specific property are set, the new general
property takes precedence. When using the reactive stack, only the new
general property is considered.

This commit fixes the auto-configuration of Spring Session to use
"server.servlet.session.timeout" as a fallback for Servlet-based web

Prior to this commit, the `StaticResourceLocation` for favicons would
point to `"/**/favicon.ico"`. This location does not reflect the current
web development landscape, since the png format and size variants are
not supported here. Also, the `"**"` pattern can be costly at runtime
and is deprecated by the new path pattern support in Spring Framework
(see gh-22833).
This commit changes the default locations to `"/favicon.*","/*/icon-*"`,
supporting common use cases such as `"/favicon.ico"`, `"/favicon.png"`
and `"/icons/icon-48x48.png"`.

Deprecate and provide alternatives for logging properties that are
specific to Logback.
The following Spring Boot properties have been changed:
* logging.pattern.rolling-file-name ->
logging.logback.rollingpolicy.file-name-pattern
* logging.file.clean-history-on-start ->
logging.logback.rollingpolicy.clean-history-on-start
* logging.file.max-size ->
logging.logback.rollingpolicy.max-file-size
* logging.file.total-size-cap ->
logging.logback.rollingpolicy.total-size-cap
* logging.file.max-history ->
logging.logback.rollingpolicy.max-history
As have the system environment properties that they map to:
* ROLLING_FILE_NAME_PATTERN ->
LOGBACK_ROLLINGPOLICY_FILE_NAME_PATTERN
* LOG_FILE_CLEAN_HISTORY_ON_START ->
LOGBACK_ROLLINGPOLICY_CLEAN_HISTORY_ON_START
* LOG_FILE_MAX_SIZE ->
LOGBACK_ROLLINGPOLICY_MAX_FILE_SIZE
* LOG_FILE_TOTAL_SIZE_CAP ->
LOGBACK_ROLLINGPOLICY_TOTAL_SIZE_CAP
* LOG_FILE_MAX_HISTORY ->
LOGBACK_ROLLINGPOLICY_MAX_HISTORY
This commit also cleans up and simplifies `DefaultLogbackConfiguration`.

Prior to this commit, the how-to documentation would say that Spring
Boot does not support the h2c protocol. While it's not supported
out-of-the-box with a configuration property, this protocol can still be
configured using server customizers.
This commit documents, with code snippets, the server customizers one
should use to configure the h2c protocol in an application - for each
supported server.
Closes gh-21997
Refactor `ConfigData` processing code to make it less awkward to
follow.
Prior to this commit the `ConfigDataLocationResolver` would take a
String location and return a `ConfigDataLocation` instance. This was
a little confusing since sometimes we would refer to `location` as the
String value, and sometimes it would be the typed instance. We also
had nowhere sensible to put the `optional:` prefix logic and we needed
to pass a `boolean` parameter to a number of methods. The recently
introduced `Orgin` support also didn't have a good home.
To solve this, `ConfigDataLocation` has been renamed to
`ConfigDataResource`. This frees up `ConfigDataLocation` to be used
as a richer `location` type that holds the String value, the `Orgin`
and provides a home for the `optional:` logic.
This commit also cleans up a few other areas of the code, including
renaming `ResourceConfigData...` to `StandardConfigData...`. It also
introduces a new exception hierarchy for `ConfigDataNotFoundExceptions`.
