By default, JUL configures a single root handler. That handler is a
ConsoleHandler. Previously, we removed all root handlers from JUL but
this is problematic in environments where other handlers are
registered with JUL and those handlers need to be retained.
0679d436 attempted to fix the problem by leaving the root handlers in
place and only adding and removing the bridge handler. This resulted
in log output from Tomcat (and anything else that uses JUL) being
duplicated.
This commit makes another attempt at tackling the problem. It attempts
to detect JUL's default configuration (a single root handler that's a
ConsoleHandler) and only removes the handler if it appears to be from
the default configuration. For environments where default JUL
configuration is being used, this will prevent duplicate logging and
for environments where custom JUL configuration is being used, this
will prevent that configuration from being undone.

Add an operation on PropertyMapper that takes care of casting. Returns
a source for the requested type if the current value is of the right
type.
Closes gh-11788
Previously, the logging system was cleaned up in response to the
root context's ContextClosedEvent being received. This event is
published early in a context's close processing. As a result, the
logging system is in cleaned up state while, for example, disposable
beans are being destroyed.
This commit reworks the logic that triggers logging system clean up
to use a disposable bean instead. Disposable beans are called in
reverse-registration order. The logging clean up bean is registered as
early as possible so that it should be the last disposable bean to
be called.
Closes gh-11676
Move the "testdb" naming logic to `DataSourceProperties` and expose
the `deduceDatabaseName` method so they can be used in
auto-configuration.
See gh-11719
Previously, Hikari's pool name was auto-configured with the value of
`spring.datasource.name` that defaults to `testdb`, which brings some
confusion.
This commit removes the default `testdb` value on
`spring.datasource.name` as it is a sane default only for an embedded
datasource. It is applied whenever applicable instead.
Closes gh-11719
This commit makes sure that `CharacterEncodingFilter` is ordered with
the `Ordered.HIGHEST_PRECEDENCE` and that other filters, potentially
reading the request body, are ordered after.
In this particular case, both `WebMvcMetricsFilter` and
`ErrorPageFilter` are now ordered at `Ordered.HIGHEST_PRECEDENCE + 1` to
avoid cases where the request body is read before the encoding
configuration is taken into account.
Closes gh-11607
This commit adds a new `spring-boot-configuration-analyzer` module that
can be added to any app to analyze its environment on startup.
Each configuration key that has a matching replacement is temporarily
transitioned to the new name with a `WARN` report that lists all of
them.
If the project defines configuration keys that don't have a replacement,
an `ERROR` report lists them with more information if it is available.
Closes gh-11301
Refactor several areas of the actuator endpoint code in order to make
future extensions easier. The primary goal is to introduce the concept
of an `ExposableEndpoint` that has technology specific subclasses and
can carry additional data for filters to use. Many other changes have
been made along the way including:
* A new EndpointSupplier interface that allows cleaner separation of
supplying vs discovering endpoints. This allows cleaner class names
and allows for better auto-configuration since a user can choose to
provide their own supplier entirely.
* A `DiscoveredEndpoint` interface that allows the `EndpointFilter`
to be greatly simplified. A filter now doesn't need to know about
discovery concerns unless absolutely necessary.
* Improved naming and package structure. Many technology specific
concerns are now grouped in a better way. Related concerns are
co-located and concepts from one area no longer leakage into another.
* Simplified `HandlerMapping` implementations. Many common concerns have
been pulled up helping to create simpler subclasses.
* Simplified JMX adapters. Many of the intermediary `Info` classes have
been removed. The `DiscoveredJmxOperation` is now responsible for
mapping methods to operations.
* A specific @`HealthEndpointCloudFoundryExtension` for Cloud Foundry.
The extension logic used to create a "full" health endpoint extension
has been made explicit.

There is a suspicion that the use of epoll is causing the intermittent
failures being tracked by gh-10569. This commit disables the use of
epoll to see if it improves the situation.
See gh-10569
Previously, the default Logback configuration set the console
appenders charset to UTF-8. This was inconsistent with the Logback
file appender and Log4j2's console and file appenders, all of which
used the platform's default.
This commit removes the configuration of the Logback console
appender's charset. This means that it will use the platform's
default charset, aligning it with the Logback file appender and
both Log4j2 appenders.
Closes gh-11611
Previously, the ServletContext was configured after any
ServletContextInitializer beans had been initialized. This meant that
any configuration class that provided such a bean would be initialized
before the ServletContext was configured. If the configuration class
used the ServletContext in its initializtaion that it would see it in
its default, unconfigured state.
This commit reworks the configuration of the ServletContext so that
it happens before any ServletContextInitializer beans are initialized.
Closes gh-10699
Improve the structure of the response and include mappings from
WebFlux and Servlet and Filter registrations in addition to the
mappings from Spring MVC.

This commit adds support for HTTP compression with reactive servers,
with the following exceptions:
* `server.compression.mime-types` and
`server.compression.exclude-user-agents` are not supported by Reactor
Netty at the moment
* `server.compression.min-response-size` is only supported by Reactor
Netty right now, since other implementations rely on the
`"Content-Length"` HTTP response header to measure the response size
and most reactive responses are using `"Transfer-Encoding: chunked"`.
Closes gh-10782
This commit partially reverts the changes made in ec470fbe. While
the started message continues to be logged before any application and
command line runners are called, the publishing of
ApplicationReadyEvent now happens after the runners have been called.
Additionally, a new event, named ApplicationStartedEvent, has been
introduced. This new event is published after the context has been
refreshed but before any application and command line runners are
called.
Closes gh-11484
The reworking of the events described above also means that either
an ApplicationReadyEvent or an ApplicationFailedEvent will be
published and the latter should never be published once the former
has been published.
Closes gh-11485
This commit adds SSL client Authentication support
to Reactor Netty and adds the relevant tests to
`AbstractReactiveWebServerFactoryTests` for all servers.
Fixes gh-11488
This commit applies `server.jetty.*` configuration properties
to Jetty when configured as a reactive web server.
It also removes some infrastructure support for Jetty 8, which
is not supported anymore in Spring Boot 2.0 (partial fix for
gh-11504).
See gh-11500
This commit applies most `server.tomcat.*` configuration
properties to Tomcat when set up as a reactive web server.
Some Servlet-specific properties are not applied:
* server.tomcat.additional-tld-skip-patterns
* server.tomcat.redirect-context-root
* server.tomcat.use-relative-redirects
Fixes gh-11334
Extract functionality from the `RegistrationBean` into a new class
designed to work with dynamic registration. Servet and Filter
registration beans now extend from `DynaimcRegistrationBean`, where as
`ServletListenerRegistrationBean` extends directly from
`RegistrationBean`.
This refactor allows the removal of `ServletListenerRegistrationBean`
deprecated methods.
Fixes gh-11344
This commit adds a new exception type that denotes the value of a
configuration key is invalid, alongside a FailureAnalyzer that reports
a human-readable report when such exception is thrown on startup.
ResourceNotFoundException being a (useless) specialization of this new
exception, its usage has been refactored to use the more general
exception type.
Closes gh-10794
This commit removes
`RestTemplateBuilder.requestFactory(ClientHttpRequestFactory factory)`
because it can be misleading. This builder class is meant to be
immutable, but calling that method and then timeout related ones will
affect the `ClientHttpRequestFactory` instance.
Instead, this method is replaced with a
`Supplier<ClientHttpRequestFactory>` that is called every time a
`RestTemplate` is being built.
That approach may reduce the reusability of request factories, but it is
much more consistent.
Closes gh-11255
This commit configures Jetty for HTTP/2 support as soon as the following
conditions are met:
* `server.http2.enabled=true`
* Both `org.eclipse.jetty:jetty-alpn-conscrypt-server` and
`org.eclipse.jetty.http2:http2-server` are on classpath
This will use the Conscrypt library for ALPN and TLS support using
native libraries shipped within the Conscrypt uber Jar. This does not
require a JVM agent or patching the JDK classes.
Closes gh-10902
Change the default JSR-303 validator used by the configuration
properties binder so that it's initialized in a background thread.
This change allows the context to carry on loading additional beans
whilst the validator is initializing.
Fixes gh-11412
Update the `PropertyMapper` interface to return arrays rather than
Lists. Since implementations are package-private it's possible for us
to control how they are used and it helps to save a little memory.
Fixes gh-11411
Remove support for the `__` environment variable list shortcut in order
to reduce complexity. The shortcut was developed before the new `Binder`
code was fully formed and isn't really necessary now since comma-lists
can be converted automatically.
Fixes gh-11410
Update ImageBanner to support animated GIFs. Animations rely on ANSI
cursor codes so don't work so well in an IDE. They do, however, work
when running the app from a terminal.

Closes gh-11118
Update `Binder` so that if a property exists, but it cannot be converted
to required type, bean binding is attempted.
Prior to this commit, if a user happened to have an environment
variable named `SERVER` the binder would fail when trying to directly
convert its `String` value into a `ServerProperties`
Fixes gh-10945
Update appropriate configuration properties to use the `Duration`
type, rather than an ad-hoc mix of milliseconds or seconds.
Configuration properties can now be defined in a consistent and readable
way. For example `server.session.timeout=5m`.
Properties that were previously declared using seconds are annotated
with `@DurationUnit` to ensure a smooth upgrade experience. For example
`server.session.timeout=20` continues to mean 20 seconds.
Fixes gh-11080
Update `StringToDurationConverter` so that the suffix is optional and
values such as `100`, `+100`, `-100` are assumed to be milliseconds.
Also add support for `@DurationUnit` to allow the unit to be changed
on a per-field basis (allowing for better back-compatibility).
Closes gh-11078
Extend `BinderConversionService` to support `Duration` parsing of
the more readable `10s` form (equivalent to 10 seconds). Standard
ISO-8601 parsing also remains as an option.
Fixes gh-11078
Update `RedisProperties` to use an actual String[] for sentinal nodes
rather than a simple String. This allows us to lean on the updated
binder to automatically trim the elements.
Fixes gh-11029
Update `SpringConfigurationPropertySource` so that the
`SystemEnvironmentPropertyMapper` is only used for the "actual" system
environment property source. This allows SystemEnvironmentProperySource
class to be used for other purposes (for example, Spring Cloud uses it
to as an override source providing decryption).
Only property sources named `systemEnvironment` or ending with
`-systemEnvironment` now have the `SystemEnvironmentPropertyMapper`
applied. The `TestPropertyValues` has been retrofitted to name the
source it adds appropriately.
Fixes gh-10840
Refine `SystemEnvironmentPropertyMapper` to support environment
variables that would have worked in Spring Boot 1.5. Specifically,
camelCase property bindings now support an additional underscore. The
recommended way to map `fooBar` is still `PREFIX_FOOBAR`, however,
`PREFIX_FOO_BAR` will now also work.
Fixes gh-10873
Refine the binder recursion rules introduced in commit f337323819 so
they only apply to Maps. Recursive List and Array binding is now no
longer allowed. Prior to this commit, binding a List that contained a
reference to itself would fail with a `StackOverflowException` if the
underlying property source was not iterable.
Fixes gh-10702
Refactor `ReactiveWebApplicationContext` implementations to align closer
with the `WebApplicationContext` implementations defined in
Spring Framework.
The following classes are now provided:
- `AnnotationConfigReactiveWebApplicationContext` -- A refreshable
reactive web context with support for `@Configuration` classes.
- `GenericReactiveWebApplicationContext` -- A non-refreshable reactive
GenericApplicationContext.
- `ReactiveWebServerApplicationContext` -- A non-refreshable reactive
GenericApplicationContext with support for server discovery.
- `AnnotationConfigReactiveWebServerApplicationContext` -- A
non-refreshable reactive `GenericApplicationContext` with support
for `@Configuration` classes and server discovery.
These classes roughly align to the following Servlet equivalents:
- `AnnotationConfigWebApplicationContext` (Spring Framework)
- `GenericWebApplicationContext` (Spring Framework)
- `ServletWebServerApplicationContext` (Spring Boot)
- `AnnotationConfigServletWebServerApplicationContext` (Spring Boot)
An additional `ConfigurableReactiveWebEnvironment` interface as also
been introduced, primarily for `@ConditionalOnWebApplication` to use.
Fixes gh-10852
This commit enables HTTP/2 support for Tomcat and Undertow, for both
Servlet-based and Reactive applications.
Enabling the `server.http2.enabled` configuration flag is enough with
Undertow.
Tomcat has a few prerequisites:
* Tomcat 8.5 requires JDK8+ and the proper libtcnative version installed
on the host
* Tomcat 9.0.x requires JDK9+
Closes gh-10043
This commit adds a new configuration properties class for configuring
HTTP/2 protocol support.
By default, this protocol is disabled as enabling it requires several
manual changes:
* configuring a web server for proper TLS and ALPN support
* configuring a proper SSL certificate
See gh-10043
This commits adds the AprLifecycleListener as a default
LifecycleListener in order to detect and use automatically the
tomcatnative library if it is available, for SSL support.
This feature can be useful for both performance reasons or for
supporting ALPN when using JDK8.
See gh-10043
Closes gh-9964
Update the logback file appender to use `SizeAndTimeBasedRollingPolicy`
rather than `FixedWindowRollingPolicy`.
Add two new properties to improve log file configuration capabilities:
- `logging.file.max-history` to limit the number of archive log files
to keep.
- `logging.file.max-size` to limit the log file size.
See gh-6352
Previously, spring.config.name was handled in such a way that its
value would replace the defaults. By constrast, spring.config.location
would add to the defaults.
Update the handling of spring.config.location so that it replaces the
defaults. This aligns its behaviour with spring.config.name. To allow
users to add additional locations a new property,
spring.config.additional-location, has been introduced. It behaves as
spring.config.location did prior to this change.

This commit adds a new customizer interface, `NettyServerCustomizer` for
customizing Reactor Netty server instances while they're being built.
Closes gh-10418
Previously, ConfigurationPropertiesBindingPostProcessor had a number
of setter methods that implied that its configuration was more mutable
than it actually is and would only have an effect when called early
on in the post-processor's lifecycle.
This commit clarifies how the post-processor can be configured by
removing the misleading setters.
Closes gh-10598
Previously, configuration properties binding would only see changes to
the environment if there was no PropertySourcesPlaceholderConfigurer
in the context. This happened because
PropertySourcesPlaceholderConfigurer wrapped the Environment in a
PropertySource, effectively hiding it from the change tracking
performed by SpringConfigurationPropertySources.
This commit updates ConfigurationPropertiesBindingPostProcessor so
that it ignores the environment property source contained by
PropertySourcesPlaceholderConfigurer and uses a composite of
the PropertySourcesPlaceholderConfigurer's other property sources and
the Environment's PropertySources instead.
Since Kotlin extensions do not apply to static
methods, this commit introduces a runApplication()
Kotlin top level function that acts as a Kotlin
shortcut for SpringApplication.run().
This shortcut avoids to require using non-idiomatic
code like SpringApplication.run(FooApplication::class.java)
and provides a runApplication<FooApplication>() alternative
(as well as an array of KClass based alternative when
multiple classes need to be passed as parameter).
It is possible to customize the application with the
following syntax:
runApplication<FooApplication>() {
setEnvironment(environment)
}
See gh-10511
When building a flattened map, the YamlProcessor from
Spring Framework, converts a null value to an empty string.
We want the null value to also keep track of its origin,
which is why this commit creates an `OriginTrackedValue`
for an empty string if the original value is null.
