Improve sanitization for list of URI types
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

Spring Boot uses sensible defaults for such keys: any key ending with the word "password", "secret", "key", "token", "vcap_services", "sun.java.command" is entirely sanitized.
|
||||
Additionally, any key that holds the word `credentials` as part of the key is sanitized (configured as a regular expression, i.e. `+*credentials.*+`).
|
||||
|
||||
If any of the keys to sanitize are URI format (i.e. `<scheme>://<username>:<password>@<host>:<port>/`), only the password part is sanitized.
|
||||
Furthermore, Spring Boot only sanitizes the sensitive portion of URIs for keys which end with "uri", "uris", "address", or "addresses".
|
||||
The sensitive portion of the URI is identified using the format `<scheme>://<username>:<password>@<host>:<port>/`.
|
||||
For example, for the property `myclient.uri=http://user1:password1@localhost:8081`, the resulting sanitized value is
|
||||
`++http://user1:******@localhost:8081++`.
