This commit documents the color converter, the explicit colors and
styles that is supports, and the implicit colors used for each log
level.

One of the options of the new `banner-mode` property is `off`. YAML maps
`off` to `false` and since we are exposing the method from the
`SpringApplication` public class we can't change the signature to accept
a `String` and do the conversion ourselves.
This commit adds a dedicated section in the guide to warn users about
that particular situation. Adding quotes around the value prevents the
conversion.
Closes gh-4600
The syntax was a bit tortured. This should clarify things and also
de-emphasise the "production" use case for the file system
properties file (we want to be cloud native don't we?).
Previously, the nested private static class would cause an error at
startup stating that it was not accessible when trying to bind the
property from the environment. The nested class should be public.
Closes gh-4323
Improve the initial PR to include a filtering of the profiles that were
already enabled via the `spring.profiles.active` property.
Also add more tests to prove that each profile is loaded only once
now.
Closes gh-4273
Logback documentation explains how to initialize the logging system and
namely how the `logback.configurationFile` system property can be used to
specify the configuration file to use.
Spring Boot has an abstraction on top of that. A user can define the
`logging.path` property regardless of the logging infrastructure it is
using.
Users following the logback documentation can be confused at first so
we're not logging a warning when we found out that the logback specific
property has been specified.

Commit adf2c44b was an attempt to prevent HSQLDB from throwing an
exception when the JVM exits. This was achieved by disabling the
application context’s shutdown hook in the tests. This had the unwanted
side effect of causing tests’ application contexts not to be closed. The
reported symptom was that @Destroy methods were no longer being invoked.
We need a different solution to the problem.
The exception was:
Caused by: org.hsqldb.HsqlException: Database lock acquisition failure: attempt to connect while db opening /closing
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.DatabaseManager.getDatabase(Unknown Source)
at org.hsqldb.DatabaseManager.newSession(Unknown Source)
... 23 common frames omitted
I originally thought this was due to a race between the application
context’s shutdown hook and HSQLDB’s shutdown hook, however HSQLDB
doesn’t use a shutdown hook. I believe that the problem is due to
an HSQLDB database being created with shutdown=true in its URL, similar
to the problem described here [1]. This will shut down the database when
the last connection to it is closed, however the shutdown will happen
asynchronously. If the JVM then runs the application context’s shutdown
hook, EmbeddedDatabaseFactory will attempt to connect to the database to
execute the SHUTDOWN command. This executes synchronously but will race
with the asynchronous shutdown that’s executing as a result of
shutdown=true in the JDBC url and the last connection to the database
being closed.
This commit reinstates the use of application context shutdown hooks in
the tests, and updates the documentation to recommend that, if a user
manually configures the URL for their embedded database, they do so
in such a way that the database doesn’t shutdown automatically, thereby
allowing the shutdown to be driven by application context close.

Spring Boot will eagerly initialize a `ConversionService` named
`conversionService` for configuration keys processing. This commit adds
a note in the documentation regarding that special behaviour.
Closes gh-4162
Previously, if Solr 5 was on the classpath, SolrAutoConfiguration
would fail with a rather cryptic error message due to a change in the
inheritance hierarchy of CloudSolrServer between Solr 4 and Solr 5.
This commit updates SolrAutoConfiguration to be conditional on a
class that exists in Solr 4 but was removed in Solr 5. This has the
effect of switching off the auto-configuration when Solr 5 is on
the classpath, allowing the auto-configuration report to be used to
identify why the configuration was disabled. The documentation has
also been updated to state that Spring Boot does not currently support
Solr 5.0.
Closes gh-2795
This commit changes the new mode-based configuration to use two new
methods – setBannerMode on SpringApplication and bannerMode on
SpringApplicationBuilder. The old methods, setShowBanner and
showBanner on SpringApplication and SpringApplicationBuilder
respectively, have been reinstated and deprecated.
Closes gh-4001
This commit adds the option to output the banner using the logger
instead of standard out. Rather than taking a boolean
spring.main.show-banner is now configured using an enum. Three values
are supported:
- LOG: the banner is logged
- CONSOLE: the banner is printed to standard out (previously true)
- OFF: the banner is switched off (previously false)
The default behavior remains unchanged; the banner will be printed to
standard out.
Closes gh-4022

Provide a general purpose Hazelcast integration (i.e. not tied to caching).
Auto-configure a `HazelcastInstance` either based on the presence of a
`Config` bean or a configuration file. Said configuration file can be
specified explicitly or automatically found from default locations.
The cache integration already supports Hazelcast so it has been reworked
to automatically reuse an existing `HazelcastInstance` if available.
Closes gh-2942
Users sometimes create beans of type Converter and don't expect that to
automatically trigger a cascade of early initialization. This change adds
a qualifier to the Converters that are used by @ConfigurationProperties,
so they can be isolated (and simple).

Spring MVC requires all handlers for the same path to be on the same handler
so if anyone wants to add new handlers for different content types they
have to copy a lot of code from BasicErrorController. This change increases
the visibility of the basic utility methods in BasicErrorController so that
custom handlers can be added easily.
Fixes gh-3828
This commit adds a new annotation, @ServletComponentScan, that can be
used to enable scanning for @WebFilter, @WebListener, and @WebServlet
annotated classes. Registration beans will be automatically created for
any classes that are found, with the configuration derived from the
annotation.
