This commit renames ApplicationHealthIndicator to PingHealthIndicator
and changes the auto-configuration so that it is now always configured
by default.
Closes gh-17926
Update the `HealthEndpoint` to support health groups. The
`HealthEndpointSettings` interface has been replaced with
`HealthEndpointGroups` which provides access to the primary group
as well as an optional set of additional groups.
Groups can be configured via properties and may have custom
`StatusAggregator` and `HttpCodeStatusMapper` settings.

Overhaul `HealthEndpoint` support to make it easier to support health
groups. Prior to this commit the `HealthIndicator` interface was used
for both regular indicators and composite indicators. In addition the
`Health` result was used to both represent individual, system and
composite health. This design unfortunately means that all health
contributors need to be aware of the `HealthAggregator` and could not
easily support heath groups if per-group aggregation is required.
This commit reworks many aspects of the health support in order to
provide a cleaner separation between a `HealthIndicator`and a
composite. The following changes have been made:
- A `HealthContributor` interface has been introduced to represent
the general concept of something that contributes health information.
A contributor can either be a `HealthIndicator` or a
`CompositeHealthContributor`.
- A `HealthComponent` class has been introduced to mirror the
contributor arrangement. The component can be either
`CompositeHealth` or `Health`.
- The `HealthAggregator` interface has been replaced with a more
focused `StatusAggregator` interface which only deals with `Status`
results.
- `CompositeHealthIndicator` has been replaced with
`CompositeHealthContributor` which only provides access to other
contributors. A composite can no longer directly return `Health`.
- `HealthIndicatorRegistry` has been replaced with
`HealthContributorRegistry` and the default implementation now
uses a copy-on-write strategy.
- `HealthEndpoint`, `HealthEndpointWebExtension` and
`ReactiveHealthEndpointWebExtension` now extend a common
`HealthEndpointSupport` class. They are now driven by a
health contributor registry and `HealthEndpointSettings`.
- The `HealthStatusHttpMapper` class has been replaced by a
`HttpCodeStatusMapper` interface.
- The `HealthWebEndpointResponseMapper` class has been replaced
by a `HealthEndpointSettings` strategy. This allows us to move
role related logic and `ShowDetails` to the auto-configure module.
- `SimpleHttpCodeStatusMapper` and `SimpleStatusAggregator`
implementations have been added which are configured via constructor
arguments rather than setters.
- Endpoint auto-configuration has been reworked and the
`CompositeHealthIndicatorConfiguration` class has been replaced
by `CompositeHealthContributorConfiguration`.
- The endpoint JSON has been changed make `details` distinct from
`components`.

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.
Fixes gh-16232
Update `@Selector` with a `match` attribute that can be used to select
all remaining path segments. An endpoint method like this:
select(@Selector(match = Match.ALL_REMAINING) String... selection)
Will now have all reaming path segments injected into the `selection`
parameter.

Previously, the sourceDocumentExtension used for the single-page
documentation was htmlsingleadoc and for the multi-page docs they
were adoc and htmladoc. When finding source files to render, the
Asciidoctor Maven Plugin looks for files with a name that ends with
one of the configured extensions. This resulted in the
index.htmlsingleadoc file matching the adoc extention in the
multi-page configuration in addition to the intended match for the
index.htmladoc. As a result both the single-page and multi-page
indexes were rendered when rendering the multi-page documentation.
In addition to this unwanted rendering, if the single-page index was
rendered after the multi-page index, the multi-page index would be
overwritten by the single-page index, leaving the multi-page docs with
the wrong index file. Asciidoctor uses File.listFiles() during its
source file discovery which is documented as having no guarantee
that the resulting array will be in any specific order. As a result,
there was also no guarantee about which index we'd end up with.

Apply checkstyle rule to ensure that private and package private
classes do not have unnecessary public methods. Test classes have
also been unified as much as possible to use default scoped
inner-classes.
Closes gh-7316
This commit also removes the workaround that required to exclude junit 4
explicitly now that a related issue in JUnit Jupiter has been fixed.
Closes gh-17266
On error cases, the "outcome" tag would be missing from recorded metrics
for the `WebClient`.
This commit fixes this issue and improves the reference documentation by
mentioning the tag values used for error cases, when the client response
is not received (I/O errors, client error, etc).
Fixes gh-17219
This commit changes the default file extension for Freemarker templates
from `*.ftl` to `*.ftlh`. This commit also enables by default the
Freemarker setting `"recognize_standard_file_extensions"` to ensure that
HTML escaping is performed by default in Spring Boot applications.
Applications should adapt to this change by changing the file extensions
of existing templates to `.ftlh`.
Closes gh-15131
As of Spring Data Moore, a new reactive template and the
corresponding repositories support have been added.
This commit auto-configures a `ReactiveElasticsearchTemplate`
with the configuration properties under the
`spring.data.elasticsearch.client.reactive` namespace.
To enable this feature, applications require both Spring Data
Elasticsearch dependencies (typically
`spring-boot-starter-data-elasticsearch`) and dependencies
for a `WebClient` (often `spring-boot-starter-webflux`).
The support for the reactive Elasticsearch repositories is
also provided.
Closes gh-16214
This commit auto-configures the Elasticsearch REST client support
as a template for Spring Data Elasticsearch. As of this commit,
using the transport client is still possible but developers
should migrate.
This commit also removes the deprecated annotation on the
Elasticsearch auto-configuration for the transport client, since
this deprecation notice is already present on the configuration
property.
Closes gh-17024
Closes gh-16542
This commit auto-configures CBOR (see https://cbor.io/) codecs in the
RSocketStrategies, using Jackson binary format support.
The required dependency is added to the rsocket starter. Binary codecs
are well suited for RSocket payloads, so this codec is added first to
the list of codecs (before the JSON one already supported).
Closes gh-16830
This commit auto-configures a prototype `RSocketRequester.Builder` bean
for building requester instances. This builder is pre-configured with
auto-detected `RSocketStrategies` (same as the server side).
Closes gh-16280
Prior to this commit, the audit auto-configuration provided
an `InMemoryAuditEventRepository` bean. This commit changes the auto-config
so that an `AuditEventRepository` is not provided and instead the auto-config
is conditional on the presence of a `AuditEventRepository` bean. This is done
to encourage the use of a custom implementation of `AuditEventRepository`
since the in-memory one is quite limited and not suitable for production.
A flag is available if the auto-configuration needs to be turned off even
in the presence of a bean.
Closes gh-16110
Prior to this commit, the http trace auto-configuration provided
an `InMemoryHttpTraceRepository` bean. This commit changes the auto-config
so that an `HttpTraceRepository` is not provided and instead the auto-config
is conditional on the presence of a `HttpTraceRepository` bean. This is done
to encourage the use of a custom implementation of `HttpTraceRepository`
since the in-memory one is quite limited and not suitable for production.
A flag is available if the auto-configuration needs to be turned off even
in the presence of a bean.

When `management.metrics.web.server.auto-time-requests` is enabled
(default=true), Spring Boot collects metrics on controller methods even
when they are not annotated with `@Timed`.
When this happens, created metrics are based on the default
`@Timed` configuration and there is no way to customize the
configuration of those auto-timed controller metrics.
This commit adds default configurations to auto-timed requests on both
client and server sides.
See gh-15988
This commit reinstates the single-page variant for the Spring Boot
reference documentation.
Now the single and multi-page variants are hosted under the same
`"html"` folder, as `"index.html"` and `"single-index.html"`.
Note that files ending in `"index.html`" are treated as index files by
the spring-doc-resources project and their table of contents do not
display a "Back to index" link.
Fixes gh-16295
As of Spring Data Moore, the Elasticsearch high level REST client is
supported for Spring Data repositories. The transport client is now
deprecated and is likely to be removed in a future Spring Data release.
This commit deprecates the transport client and marks all the associated
configuration properties as deprecated. The Spring Boot starter depends
on the `spring-data-elasticsearch` project, which now depends on both
transport client and high level REST client.
This commit also deprecates the Jest client, as Spring Boot will focus
on supporting the high level REST client and the reactive client
provided by Spring Data - both being in sync with the fast release pace
of Elasticsearch.
Closes gh-15008
Previously, if the `server.use-forward-headers` property
was set to true, X-Forwarded-* headers support was provided
at the server level. The property has been deprecated in favor
of `server.forward-headers-strategy` which can be also be configured
to use Spring's forwarded header support apart from native server support.
Closes gh-5677
This commit adds support for RSocket server applications.
The auto-configuration will either add RSocket support to an existing
Reactor Netty server in a WebFlux application (as a WebSocket endpoint),
or bootstrap a brand new RSocket server instance.
Spring Boot will also auto-configure the Spring Messaging infrastructure
that supports Controller beans with `@MessageMapping` annotated methods.
Fixes gh-16021
This commit also adds tests to ensure that the child
management context works when lazy initialization is
enabled. Also, it adds a BeanFactoryPostProcessor to
the child context so that the server is created and
listening for requests but other beans in the child
context are not created until requested.
