This commit modifies the actuator `EnvironmentEndpoint` to allow
primitive wrapper types to be serialized in the response data
structure.
Fixes gh-24307
When `EnvironmentEndpoint` is building a response to return to the
web infrastructure, it creates a data structure containing all
property values from all property sources. Prior to this commit, it
was possible for the response data structure to contain property
values that were not serializable to JSON by Jackson, which would
cause an exception to be thrown by the web infrastructure. This
commit ensures the data structure is serializable to JSON by
ensuring property values are primitives or Strings, and returning
a placeholder value if a property value is of any other type.
Fixes gh-23805
This commit adds support for Redis cache metrics. Users can opt-in for
statistics using the "spring.cache.redis.enable-statistics" property.
Closes gh-22701
Constructor calls like new AtomicInteger(0) cause a volatile write that
can be saved in cases where the constructor parameter is the default
value.
See gh-23575
Prior to this commit, Actuator would sanitize properties values when
serializing them on the dedicated endpoint. Keys like "password" or
"secret" are entirely sanitized, but other keys like "uri" or "address"
are considered as URI types and only the password part of the user info
is sanitized.
This commit fixes the sanitization process where lists of such URI types
would not match the first entries of the list since they're starting
with `'['`. This commit improves the regexp matching process to sanitize
all URIs within a collection.
The documentation is also updated to better underline the processing
difference between complete sanitization and selective sanitization for
URIs.
Fixes gh-23037
Prior to this commit, the `WebClientExchangeTags`, when given a request
without a string template, would only get the request path to create the
"uri" tag for metrics. This is inconsistent with the
`RestTemplateExchangeTags`, which are taking the full request URI minus
the protocol+host+port.
This commit aligns the `WebClientExchangeTags` behavior in this case.
Closes gh-22832
