Refine `DataSourceAutoConfiguration` conditions so that an empty
`spring.datasource.url` property can be used to enable the embedded
source.
Fixed gh-20996
Previously, a condition checked the value of "spring.datasource.url" to
determine if an embedded database has to be created as a fallback. When
the value is set with an unresolved placeholder, this fails even if
the DataSource is going to created by another mean ultimately.
This commit makes a more conservative check by only checking the
presence of the property rather than its value.
Closes gh-20438
Previously, the presence of a `ConsumerFactory` bean would make the
auto-configured one to back off, leading to a failure down the line if
no available instance matches the generics criterion. This commit
improves the auto-configuration to create a `ConsumerFactory<?,?>`
behind the scenes if none is available.
Closes gh-19221
This commit makes sure that a fallback embedded datasource is not
created if no suitable connection pool is found and an url has been
explicitly registered.
This is consistent with EmbeddedDataSourceConfiguration as it is using
EmbeddedDatabaseBuilder behind the scenes and the latter does not
honour the configured URL anyway.
Closes gh-19192
Prior to this commit, the `ErrorController` would override the original
error response status if the error map cannot be written due to content
negotiation with the HTTP client. In that case, the error handling
infrastructure returns a `406 Not Acceptable` response.
This commit improves the `ErrorController` so that
`HttpMediaTypeNotAcceptableException` instances thrown by that
controller are not returned as is but instead we write the error
response with an empty body and the original HTTP error status.
Fixes gh-19545

Prior to this commit, there was no distinction between explicitly setting
forward headers strategy to a value of NONE and not setting it at all.
This meant that in a cloud environment, a cloud provider was always checked
to see if it was active and using forward headers and there was no way to
prevent that.
This commit changes the default value of the property to null so that there
is a way to determine if the property was explicitly set to NONE.
Fixes gh-19333
Prior to this commit, the Couchbase auto-configuration would use the
bucket credentials when RBAC is configured. This commit ensures that
RBAC is used in that case.
This commit also adds new configuration properties to customize the
bootstrap ports for Couchbase:
* `spring.couchbase.env.bootstrap.http-direct-port`
* `spring.couchbase.env.bootstrap.http-ssl-port`
Fixes gh-19393
