The versions of Jackon's bom and the versions of Jackson are often
not the same. For example, at the time of writing, the latest bom
version is 2.9.9.20190807 but the latest version of Jackson's core
is 2.9.9 and the latest version of Jackson's databind is 2.9.9.3.
spring-boot-dependencies using a property, jackson.version, to control
the version of jackson-bom that is imported. To make it clear that the
version property controls the version of Jackson's bom and not of
Jackson itself, this commit deprecates jackson.version in favour of
a new jackson-bom.version property.
An additional benefit of this change is that it addresses a problem
when using Gradle and the dependency management plugin. Jackson's bom
uses a jackson.version property to control the version
of core Jackson modules. This names clashes with the name of the
property used by spring-boot-dependencies. Specifying a custom
jackson.version to control the version of the bom that is imported
would also have the unwanted side-effect of customizing the version of
the core Jackson modules declared in Jackson's bom.
Fixes gh-17808
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`.

This commit improves InvalidConfigurationPropertiesException failure
analysis by adding a dedicated description when a single autowiring
constructor is found. When @Component is removed, such constructor is
used for properties binding and will not apply the same semantics as
before.

The userDn and password in LdapContextSource are not nullable. The
default values for userDn and password in LdapProperties are null. When
the values are set to null there will eventually be a
NullPointerException during
AbstractContextSource#setupAuthenticatedEnvironment since HashTable
doesn't allow null for values.
