Health contributor exclusion rules aren't applied to child contributors #29251
Description
Excluding a composite health contributor by the composite name no longer works in spring boot 2.6. It worked previously in spring boot 2.5.
Potentially caused by #23027
Here is an example application, with a failing unit test... health-group-composite-test.zip
The excludefoo_endpoint_should_not_contain_foo_indicators test fails with spring-boot 2.6.2. If you change the application to use spring boot 2.5.8, the test will pass.
The application defines a composite health contributor named foo as follows:
@Bean CompositeHealthContributor fooHealthContributor() { return CompositeHealthContributor.fromMap(Map.<String, HealthIndicator>of( "foo-1", () -> Health.up().build(), "foo-2", () -> Health.up().build() )); }And then creates a health group named exclude-foo that excludes that contributor:
management: endpoint: health: show-details: always group: exclude-foo: include: "*" exclude: foo show-details: alwaysWith spring boot 2.5.8, the exclude-foo group endpoint does not show the foo indicators (as expected)...
