Prior to this commit, there was a property server.error.include-details
that allowed configuration of the message and errors attributes in a
server error response.
This commit separates the control of the message and errors attributes
into two separate properties named server.error.include-message and
server.error.include-binding-errors. When the message attribute is
excluded from a servlet response, the value is changed from a
hard-coded text value to an empty value.
Fixes gh-20505
Prior to this commit, default error responses included the message
from a handled exception. When the exception was a BindException, the
error responses could also include an errors attribute containing the
details of the binding failure. These details could leak information
about the application.
This commit removes the exception message and binding errors detail
from error responses by default, and introduces a
`server.error.include-details` property that can be used to cause
these details to be included in the response.

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.

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.

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.

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,
and dependency management.
Closes gh-19798
The Elasticsearch transport client has been deprecated since Spring Boot
2.2.0 and is about to be removed from Spring Data Elasticsearch and
Elasticsearch itself in their next major releases.
The available REST client support variants are now the preferred way of
using Elasticsearch features.
Closes gh-19668
This commit also changes the request matcher for MVC
endpoints to use an AntPathRequestMatcher instead of an
MvcRequestMatcher. The endpoint is always available
under the mapped endpoint path and this way the same matcher
can be used for both MVC and Jersey.

Missing change logs would lead to an exception even
if the checkChangeLogLocation was set to false. Spring Boot's check
would pass but Liquibase would fail later making this property redundant.

The `reactor-tools` dependency now brings a new Reactor Debug Agent
which instruments loaded classes for better Reactor stacktraces.
This commit removes the `spring.reactor.stacktrace-mode.enabled`
configuration property since the related Reactor Hook is about to be
removed.
As a replacement, we're introducing `spring.reactor.debug-agent.enabled`
which tells whether the Reactor Debug Agent should be loaded, given that
the `reactor-tools` dependency is available. This option is enabled by
default, since adding the dependency on classpath is a strong signal
already.
Fixes gh-17128
