This commit moves the core Liveness and Readiness support to its own
`availability` package. We've made this a core concept independent of
Kubernetes.
Spring Boot now produces `LivenessStateChanged` and
`ReadinessStateChanged` events as part of the typical application
lifecycle.
Liveness and Readiness Probes (`HealthIndicator` components and health
groups) are still configured only when deployed on Kubernetes.
This commit also improves the documentation around Probes best practices
and container lifecycle considerations.
See gh-19593
Prior to this commit and as of Spring Boot 2.2.0, we would advise
developers to use the Actuator health groups to define custom "liveness"
and "readiness" groups and configure them with subsets of existing
health indicators.
This commit addresses several limitations with that approach.
First, `LivenessState` and `ReadinessState` are promoted to first class
concepts in Spring Boot applications. These states should not only based
on periodic health checks. Applications should be able to track changes
(and adapt their behavior) or update states (when an error happens).
The `ApplicationStateProvider` can be injected and used by applications
components to get the current application state. Components can also
track specific `ApplicationEvent` to be notified of changes, like
`ReadinessStateChangedEvent` and `LivenessStateChangedEvent`.
Components can also publish such events with an
`ApplicationEventPublisher`. Spring Boot will track startup event and
application context state to update the liveness and readiness state of
the application. This infrastructure is available in the
main spring-boot module.
If Spring Boot Actuator is on the classpath, additional
`HealthIndicator` will be contributed to the application:
`"LivenessProveHealthIndicator"` and `"ReadinessProbeHealthIndicator"`.
Also, "liveness" and "readiness" Health groups will be defined if
they're not configured already.

This commit upgrades to the Couchbase SDK v3 which brings the following
breaking changes:
* Bootstrap hosts have been replaced by a connection string and the
authentication is now mandatory.
* A `Bucket` is no longer auto-configured. The
`spring.couchbase.bucket.*` properties have been removed
* `ClusterInfo` no longer exists and has been replaced by a dedicated
API on `Cluster`.
* `CouchbaseEnvironment` no longer exist in favour of
`ClusterEnvironment`, the customizer has been renamed accordingly.
* The bootstrap-related properties have been removed. Users requiring
custom ports should supply the seed nodes and initialize a Cluster
themselves.
* The endpoints-related configuration has been consolidated in a
single IO configuration.
The Spring Data Couchbase provides an integration with the new SDK. This
leads to the following changes:
* A convenient `CouchbaseClientFactory` is auto-configured.
* Repositories are configured against a bucket and a scope. Those can
be set via configuration in `spring.data.couchbase.*`.
* The default consistency property has been removed in favour of a more
flexible annotation on the repository query methods instead. You can now
specify different query consistency on a per method basis.
* The `CacheManager` implementation is provided, as do other stores for
consistency so a dependency on `couchbase-spring-cache` is no longer
required.

This commit configures Spring Data Couchbase explicitly rather than
relying on the abstract configuration class. This has the advantage of
simplifying the auto-configuration and let it us proxy-free
configuration classes.
Spring Boot no longer uses or interacts with CouchbaseConfigurer. Users
relying on that to teach Spring Boot which components to use should
rely on `@Primary` flag instead in case of multiple beans of the same
type.
`CouchbaseConfiguration` is no longer public as extending from it is
no longer necessary. If the `CouchbaseEnvironment` has to be
customized, a `CouchbaseEnvironmentBuilderCustomizer` bean can be
registered to tune the auto-configured environment.
Closes gh-20533
Liquibase auto configuration is extended with clearCheckSums to allow
to clear all checksums in the current changelog, so they will be
recalculated upon the next update.
See gh-20417
Unfortunately, while redundant for new applications, removing the
leading slash adversely affected existing application upon upgrades as
it caused Liquibase to re-apply every change log.
Closes gh-20177
This commit adds support for gracefully shutting down the embedded
web server. When a grace period is configured
(server.shutdown.grace-period), upon shutdown, the web server will no
longer permit new requests and will wait for up to the grace period
for active requests to complete.
Closes gh-4657
This commit adds a new auto-configuration for RSocket support in Spring
Integration.
Given an application with `spring-messaging`, `spring-integration-rsocket`
and RSocket dependencies, developers are now able to leverage Spring
Integration features with RSocket.
It is now possible to configure an RSocket server with
`"spring.rsocket.server.*"` properties and let it use
`IntegrationRSocketEndpoint` or `RSocketOutboundGateway` components to
handle incoming RSocket messages. This infrastructure can handle Spring
Integration RSocket channel adapters and `@MessageMapping` handlers
(given `"spring.integration.rsocket.server.message-mapping-enabled"`is
configured.
If the `"spring.integration.rsocket.client.host"` and
`"spring.integration.rsocket.client.port"` (for TCP protocol), or
`"spring.integration.rsocket.client.uri"` (for WebSocket) is configured
then a `ClientRSocketConnector` will be configured accordingly.

This commit adds auto-configuration support for Spring Data R2DBC. If a
`ConnectionFactory` and Spring Data are available, scanning of reactive
repositories is enabled.
This commit also adds a starter to bring R2DBC and the necessary Spring
Data libraries.

This commit adds auto-configuration for R2DBC. If R2DBC is on the
classpath, a `ConnectionFactory` is created similarly to the algorithm
used to create a `DataSource`.
If an url is specified, it is used to determine the R2DBC driver and
database location. If not, an embedded database is started (with only
support of H2 via r2dbc-h2). If none of those succeed, an exception is
thrown that is handled by a dedicated FailureAnalyzer.
To clearly separate reactive from imperative access, a `DataSource` is
not auto-configured if a `ConnectionFactory` is present. This makes sure
that any auto-configuration that relies on the presence of a
`DataSource` backs off.
There is no dedicated database initialization at the moment but it is
possible to configure flyway or liquibase to create a local `DataSource`
for the duration of the migration. Alternatively, if Spring Data R2DBC
is on the classpath, a `ResourceDatabasePopulator` bean can be defined
with the scripts to execute on startup.

This commit brings MongoClientFactory and ReactiveMongoClientFactory
into functional alignment and reduces duplication in the classes
and their tests.
There are no behavior changes to ReactiveMongoClientFactory.
MongoClientFactory now throws an exception when a URI is configured
along with a host, port, or credentials, where it previousy ignored
host, port, and credentials silently. MongClientFactory now also
supports MongoClientSettingsBuilderCustomizers.
Fixes gh-20019
This commit makes sure that a fallback embedded datasource is not
created if no suitable connection pool is found and an url has been
explicitly registered.
This is consistent with EmbeddedDataSourceConfiguration as it is using
EmbeddedDatabaseBuilder behind the scenes and the latter does not
honour the configured URL anyway.
Closes gh-19192
This commit makes sure to create a HazelcastClient if an instance name
is provided in configuration and if no such client already exists. This
harmonizes the behaviour with of the server counter-part.

This commit changes the classpath check condition to verify that the
core module of the MongoDB driver is present. Previously, we were only
checking for the presence of the sync driver, making embedded support
unavailable with the reactive variant.

For consistency with SpringApplication, this commit disables bean
overriding by default in ApplicationContextRunner. Bean overriding can
be enabled again using withAllowBeanDefinitionOverriding.

This commit hard codes the default value so that the annotation
processor picks it up. The default value is tested for consistency so
this is acceptable as providing the default value in the metadata
requires to hard code it anyway.
The Cassandra v4 driver does not longer have automatic local DC inference
from contact points. As a result, the "local-datacenter" property must be
set with the default load balancing policy and the contact points must
be of that data center.
This commit adds a new property for the local datacenter so that it can
be specified without the use of a customizer.

This commit changes uses of ClassLoader.loadClass to Class.forName for

This class was mistakenly marked as deprecated in 2.2.0 instead of deprecated
in 2.3.0. This resulted in the class being deleted as part of the 2.3.0
cleanup.
Putting it back in place now with the correct deprecation noted.
Closes gh-19861
Update all dependencies declarations to use the form `scope(reference)`
rather than `scope reference`.
Prior to this commit we declared dependencies without parentheses unless
we were forced to add them due to an `exclude`.
Replace Gradle single quote strings with the double quote form
whenever possible. The change helps to being consistency to the
dependencies section where mostly single quotes were used, but
occasionally double quotes were required due to `${}` references.
The Spring Cloud Connectors project has been deprecated in favor of the
Java CFEnv project. The Boot auto-configuration and starter that support
Connectors were deprecated in Boot 2.2.
This commit removes the Connectors auto-configuration, starter,

This change ensures that each test in a test suite that shares an

Change the default `BootstrapMode` for auto-configured `JpaRepositories`
to `BootstrapMode.DEFERRED` to allow the initialization of
`EntityManagerFactory` to be parallelized for increased startup efficiency.
Prior to this change, the default BootstrapMode for all auto-configured
Spring Data repositories was `BootstrapMode.DEFAULT`.

This paves the way for publishing Gradle module metadata once the
problem caused by snapshot versions and our two-step publication
process has been addressed.

Previously, enforcedPlatform dependencies were using to pull in the
constraints defined in spring-boot-dependencies and
spring-boot-parent and applied them strictly so that the constrained
version had to be used. This worked as intended in Spring Boot's own
build but incorrectly enforced those same strict version requirements
on external consumers of Spring Boot's modules.
This commit reworks how Spring Boot defines its internal dependency
management so that platform dependencies are exposed to external
consumers while enforced platform dependencies are using internally.

The Elasticsearch transport client has been deprecated since Spring Boot
2.2.0 and is about to be removed from Spring Data Elasticsearch and

The available REST client support variants are now the preferred way of
using Elasticsearch features.
Closes gh-19668
Prior to this commit, HTTP client builders auto-configured by Spring
Boot would be eagerly instantiating resources, even if those were not
used by the application.
This commit makes the `RestTemplateBuilder` bean as Lazy.
`WebClient.Builder` was already a prototype bean, but some of its
dependencies could consume resources, like the `HttpClientConnector` and
the related infrastructure. This commit makes those pieces lazy.
Note that since those components are meant to help instantiate actual
HTTP clients for application components, making them lazy won't make any
difference at runtime since they'll be used during context refresh, or
they won't be used at all.
Closes gh-19549
Prior to this commit, the `ErrorController` would override the original
error response status if the error map cannot be written due to content
negotiation with the HTTP client. In that case, the error handling
infrastructure returns a `406 Not Acceptable` response.
This commit improves the `ErrorController` so that
`HttpMediaTypeNotAcceptableException` instances thrown by that
controller are not returned as is but instead we write the error
response with an empty body and the original HTTP error status.
Fixes gh-19545
See gh-19522
Prior to this commit, there was no distinction between explicitly setting
forward headers strategy to a value of NONE and not setting it at all.
This meant that in a cloud environment, a cloud provider was always checked
to see if it was active and using forward headers and there was no way to
prevent that.
This commit changes the default value of the property to null so that there
is a way to determine if the property was explicitly set to NONE.

Prior to this commit, the Couchbase auto-configuration would use the
bucket credentials when RBAC is configured. This commit ensures that
RBAC is used in that case.

This commit fixes the setup of tests using component scan. Previously,
a configuration used an include filter to only include a particular
configuration class in a given package. Unfortunately, include filters
do not prevent regular filters by default and the definition did not
have the intended behaviour.
This commit disables default filters so that only the specified include
filter is applied.
This commit movers the auto-configuration of RabbitTemplate to a
dedicated class that can be reused to create additional template with
