Previously an in-memory database that wasn’t pooled (an
EmbeddedDatabase) would be shutdown when the context restarted, but
an in-memory database wrapped in a connection pool was not. This meant
that the former would be be wiped clean after each restart, whereas the
latter would not. In addition to being inconsistent, this also
caused problems with schema.sql and data.sql scripts when using
DevTools. If you were using an in-memory database wrapped in a
connection pool, a failure may occur during a restart as the scripts
were not being run against in clean database.
This commit adds an auto-configured bean to DevTools that, when the
context is being closed, will execute “SHUTDOWN” if it identifies that
the DataSource is not an EmbeddedDatabase and is for an in-memory
database.

Previously, WebSocketMessagingAutoConfiguration added a single
additional converter. This was a MappingJackson2MessageConverter
configured with the auto-configured ObjectMapper.
AbstractMessageBrokerConfiguration places additional converters before
any of the default converters. This meant that the auto-configuration
had the unwanted side-effect of changing the ordering of the
converters. A MappingJackson2MessageConverter was now first in the
list, whereas, by default, it's last in the list after a
StringMessageConverter and a ByteArrayMessageConverter.
This commit updates WebSocketMessagingAutoConfiguration so that it
switches off the registration of the default converters and registers
a StringMessageConverter, ByteArrayMessageConverter and
MappingJackson2MessageConverter in that order. A test has been
added to verify that the types of these three converters match
the types of the default converters. A second test that verifies
that String responses are converted correctly has also been added
alongside the existing test that verified the behaviour for JSON
responses.

When the `locations` attribute is set for a given bean annotated with
`@ConfigurationProperties`, the configuration at these specified
locations take precedence over any other property sources. This means
that such values can't be overridden by a system property or a command
line switch for instance.
This commit clarifies this rules in the documentation.
Closes gh-5111
Hikari and Commons DBCP2 are already validating that the connection is
valid before borrowing it from the pool. This commit makes that behaviour
consistent by enabling that feature for the Tomcat and Commons DBCP data
sources.
Since a validation query is required in those cases, the infrastructure
of `DataSourceHealthIndicator` has been merged in a single place: the
`DatabaseDriver` enum provides not only the driver class names but also
the validation query, if any.
Closes gh-4906
DriverClassNameProvider is unused but was probably restored by a merge
commit at some point. It wasn't obvious and updated that class rather
than `DatabaseDriver`.
This commit updates `DatabaseDriver` and deletes
`DriverClassNameProvider`.
Closes gh-5076
When `@EnableConfigurationProperties` is defined, Spring Boot
automatically registers a bean in the context for each class specified
on the annotation. Previously, the name of the bean only included the
prefix which leads to conflict if two different classes use the same
prefix.
This commit changes the bean name structure to be <prefix>-<fqn> where
prefix is the prefix used on the annotation and <fqn> the fully qualified
name of the target class.
Closes gh-4395
