Previously, the presence of a `ConsumerFactory` bean would make the
auto-configured one to back off, leading to a failure down the line if
no available instance matches the generics criterion. This commit
improves the auto-configuration to create a `ConsumerFactory<?,?>`
behind the scenes if none is available.
Closes gh-19221
This commit upgrades the algorithm when trailing slash are to be
ignored. Previously a root URI (i.e. "/") would result to to empty
string which is an issue for monitoring system that requires tag values
to be non empty. If the URI is a single character, the trailing is not
applied and "/" is left as is.
Closes gh-20536
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.

This commit adds support for setting the image name and builder
parameters of the Gradle bootBuildImage task using command-line
options as an alternative to DSL configuration.

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.
Closes gh-19593
Prior to this commit, `HealthContributor` would be exposed under the
main `HealthEndpoint` and subgroups, `HealthEndpointGroups`. Groups are
driven by configuration properties and there was no way to contribute
programmatically new groups.
This commit introduces the `HealthEndpointGroupsRegistry` (a mutable
version of `HealthEndpointGroups`) and a
`HealthEndpointGroupsRegistryCustomizer`. This allows configurations to
add/remove groups during Actuator auto-configuration.
Closes gh-20554
This commit adds a new `"spring.main.cloud-platform"` configuration
property that overrides the `CloudPlatform` detection.
This makes it easier to enable paltform-specific features when running
applications locally or when writing integration tests.
Closes gh-20553
This commit enables javadoc generator for the Spring Boot Maven plugin.
This also harmonizes the structure of the documentation, with an `/api`
and a `/reference` root directories for the javadoc and the reference
guide respectively.
Closes gh-20127
`compileJava.dependsOn(processResources)` is not enough to ensure the
correct behavior. Using `dependsOn` only affects the execution order
(`processResources` before `compileJava`) but not the up-to-date check
of `compileJava`. After modifying
`META-INF/additional-spring-configuration-metadata.json`, the
`processResouces` task will considered out-of-date and will be
re-executed, but after that `compileJava` will still be considered
up-to-date which causes the changes not to be merged into
`META-INF/spring-configuration-metadata.json`
With this change the up-do-date check of `compileJava` is affected,
too. Therefore, it will correctly re-execute the
configuration-processor when
`META-INF/additional-spring-configuration-metadata.json` was changed.
See gh-20323
This commit adds support for setting the image name and builder
parameters of the Maven spring-boot:build-image goal using command-line
properties as an alternative to plugin configuration in pom.xml. Per
Maven conventions, a value in pom.xml configuration will override a
command-line property when both are provided.

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
This commit adds configuration to the Spring Boot Gradle plugin that
allows the names and contents of layers to be customized in the build
configuration.

Maven's war plugin does not support reproducible builds, resulting in
the entries in the war file not being written in a consistent order
from build to build.
Closes gh-20176
Previously, any HTTP request to an endpoint that included a principal
would bypass the cache. This prevented authenticated requests from
making use of the cache and its configurable time-to-live.
This commit updates the caching operation invoker to include the
principal, if any, in its cache key. As a result, requests that
include a principal will make use of the cache, potentially returning
the result of a previous invocation of the same endpoint by the same
principal.
Closes gh-19538
This commit adds an additional 'layers/configuration' property that can
be used to refer to a separate layers configuration file. This separate
file defines:
* The layers and their order of precedence,
* How libraries are handled using filters that match against the
coordinates of each library, and
* How classes are handled using filters that match against the location
of the entry
An XSD to validate the XML configuration file is available.

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.

Previously, DevToolsDataSourceCondition called
getBeanNamesForType(Class) which could trigger unwanted initialization
of lazy init singletons and objects created by FactoryBeans.
This commit updates DevToolsDataSourceCondition to prohibit eager
init when getting the names of the beans of a particular type.
Fixes gh-20430
Previously, DependencyCustomizer's ifAllResourcesPresent method
would return a customizer that added modules if any of the resources
were present. This commit corrects this behaviours so that modules are
only added if all resources are present.
Fixes gh-20418
TomcatReactiveWebServerFactory's getTomcatWebServer is described as
being a hook point the can be overrideden to return a different
TomcatWebServer or to apply additional processing to the Tomcat
server. Previously, this did not work as the method was not called
to create the TomcatWebServer instance. Instead, TomcatWebServer was
instantiated and returned directly.
This commit updates TomcatReactiveWebServerFactory to call
getTomcatWebServer to create the TomcatWebServer instance. A test
has also been added to verify that the method is now used.
Fixes gh-20386
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.

Standalone Jetty will, by default, include a Connection: close header
in all responses once graceful shutdown has begun. Previously, the
way in which we were shutting Jetty down did not cause this to happen.
This commit updates JettyGracefulShutdown to shut down each connector.
This causes Jetty to send the Connection: close header, aligning its
behaviour more closely with what it does when used standalone. The
tests have also been updated to verify this behaviour and to ensure
that the correct port is used for requests even once the connector is
no longer bound and the web server no longer knows its ephemeral port.
See gh-4657
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
When a request to the /actuator/env/{toMatch} endpoint does not match a
property, a response status 404 was being returned along with a body
containing the existing property sources. This commit removes the body
from the response to be more consistent with a typical 404 response.
Fixes gh-20314
This commit relaxes the class condition to ConnectionFactory, checking
if the connection factory is a connection pool and bind its metrics to
the registry accordingly.

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 a test slice for Spring Data R2DBC. When
`DataR2dbcTest` is added on a test, only Spring Data R2DBC repositories
and the infrastructure that they need is auto-configured.
Contrary to the JDBC counterpart, the `ConnectionFactory` is not swapped
by an embedded database.

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.
