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- The `HealthStatusHttpMapper` class has been replaced by a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- The `HealthWebEndpointResponseMapper` class has been replaced
by a `HealthEndpointSettings` strategy.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.
Closes gh-17743
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).
