This commit restores the highest precedence of reactive
HealthContributor over imperative one. Previously, both would be
registered, leading to duplicate entries in health output.
Closes gh-18748
The configuration property is always cleared before bean instantiation
because the problem with bean instantiation might not necessarily be the
last bound property.
Fixes gh-18704
Previously, if a bean definition had no resource description, the
failure analysis description would state that the been had been
defined in null which was of no use to the user.
This commit updates the failure analysis to omit information about
where the bean was definied when the definition has no resource
description.
Fixes gh-18721
Update `ConfigurationPropertiesBean.getAll()` to limit the candidate
beans that will actually need a `getBean()` call. Prior to this commit
calling `getAll()` would trigger a get of every bean in the context,
some of which might fail.
Fixes gh-18714
Update `DataSourceHealthContributorAutoConfiguration` so that any
`AbstractRoutingDataSource` beans are still included in the overall
health. Prior to this commit, a regression in Spring Boot 2.2 meant
that if a single routing bean was found an `IllegalArgumentException`
would be thrown.
In Spring Boot 2.1 all `AbstractRoutingDataSource` would be filtered
from the results, but if no results existed the following was returned:
"details": {
"db": {
"status": "UNKNOWN"
},
In Spring Boot 2.2 we now always include routing datasource beans, even
if other non-routing database beans are found. The health details
includes `"routing" : true` to help users disambiguate any results.
Fixes gh-18661
Update `NamedContributorsMapAdapter` to check for `null` keys or values
during construction. Also update `HealthEndpointSupport` to allow
null component entries.
See gh-18687
Update `HealthEndpointSupport` so that aggregate elements that don't
ultimately provide a contribution are filtered out. Prior to this
commit an NPE was returned when calculating the aggregate status.
Fixes gh-18687
