Previously, if the Spring Boot build plugins got a connection error
when attempting to communicate with a Docker daemon (for example,
when the daemon isn't running), the error message made it appear that
the daemon returned an HTTP error code. This commit makes a connection
error distinct from an HTTP error response code to make it easier for
the user to diagnose the root cause of the problem.
Fixes gh-21554
Previously, an AvailabilityChangeEvent was published when the servlet
and reactive web server application contexts were closed, irrespective
of whether or not the context was active. This caused problems when
the context was not active due to a refresh failure as the event
publication could then trigger bean creation and post-processing that
relied upon beans that had been destroyed when cleaning up after the
refresh failure. The most commonly seen symptom was a missing
importRegistry bean that is required by ImportAwareBeanPostProcessor.
This commit updates the two web server application contexts to only
publish the availability change event if the context is active.
Fixes gh-21588
Previously, the productionRuntimeClasspath configuration was created
without any attributes. This caused problems with multi-project
dependency resolution as there was insufficient information for Gradle
to determine which variant of a dependency should be used by the
productionRuntimeClasspath configuration.
This commit updates the configuration to have three attributes, each
configured with the same values as those of Gradle's own
runtimeClasspathConfiguration.
Fixes gh-21549
This commit mentions the `management.health.probes.enabled`
configuration property in the Kubernetes Probes section of the Actuator
chapter.
Enabling this property is required if we need to expose Kubernetes
Probes in a non-Kubernetes environment.
Fixes gh-21505
Prior to this commit, Spring Boot would auto-configure Spring MVC and
would keep the default `UrlPathHelper` configuration.
Since Spring Boot is in charge of configuring the `DispatcherServlet`
and its mapping, it is in a position to optimally configure the
`UrlPathHelper` depending on the chosen mapping.
This commit sets the `alwaysUseFullPath` property of `UrlPathHelper` if
the Servlet mapping is `"/"`. This is more efficient since this
configuration requires less processing of the request path.
Closes gh-21499
This commit adds the support for static and templated welcome pages with
Spring WebFlux. The implementation is backed by a `RouterFunction`
that's serving a static `index.html` file or rendering an `index` view.
Closes gh-9785
Prior to this commit, a default tag of 'latest' was used when no tag
was included in the builder image name used when building an image in
the Maven and Gradle plugins, but the tag for the run image was left
empty if it was not provided. This resulted in errors when pulling
the run image from an image repository. This commit applies the
same tag defaulting logic to the run image name.
Fixes gh-21532
This commit updates the MavenPublishingConventions to use HTTPS to
link to the Apache license. The configuration of NoHTTP has also
been reworked so that it will correctly find usch uses of http://
URLs.

Prior to this commit, the published Maven POMs would not pass the Maven
Central mandatory checks.
This commit adds the missing project name and description metadata for
most artifacts. The Spring Boot Gradle plugin artifact was also missing
this information and this is now added in the plugin metadata itself.
This is also updating the project page URL which is now hosted directly
on spring.io.
Fixes gh-21457
There's a bug in Undertow that means it may leak a file handle is
the server is stopped immediately after a response to an SSL request
has been received. The stop processing races with Undertow's SSL
support tidying things up after sending the response. When the stop
processing wins, the tidying up fails with a NullPointerException that
prevents an input stream from being closed. On Windows, the input
stream remaining open prevents JUnit from being able to clean up its
temporary directory.
This commit uses Awaitility to wait for the file that's being served
over SSL to be deleted before stopping the server. On Windows, this
will delay the stop processing from beginning until after the tidy up
that's performed after sending the response has been completed,
hopefully eliminating the race condition that resulted in the input
stream being left open.
Fixes gh-21172
Update `EndpointDiscoverer` so that `@Endpoint` and `@EndpointExtension`
beans are created as late as possible.
Prior to this commit, endpoint beans and extension beans would be
created during the discovery phase which could cause early bean
initialization. The problem was especially nasty when using an embedded
servlet container since `ServletEndpointRegistrar` is loaded as the
container is initialized. This would trigger discovery and load all
endpoint beans, including the health endpoint, and all health indicator
beans.

Restore the `getUseRelativeRedirects` method with a `Boolean` object

Gradle's metadata for a platform does not provide a way to define
exclusions in the same way that can be done in <dependencyManagement>
in a Mavne bom. This means that Gradle 6 users lose the exclusions
that are defined in the pom as Gradle 6 will use the metadata rather
than the pom.
Until such a time as Gradle's metadata supports the configuration of
such exclusions we can avoid the problem by disabling the metadata's
publication.
Fixes gh-21350
This commit expands the migration check to all deprecated properties,
not only the ones that have been effectively removed. This provides more
information upfront, including keys that still work in the current
release but will need to be renamed sooner than later anyway.

Attempt to improve the performance of the `ConfigurationPropertySource`
adapters `containsDescendantOf` method. The method now operates on
arrays rather than iterators and reduces the inner for-loop when
possible.
See gh-21416
Prior to this commit, if a DOCKER_HOST environment variable was present
when attempting to communicate with a Docker daemon, it was assumed
that the value of that variable was an address that could be used to
create an HTTP connection to a remote daemon. In some cases, the value
of the variable is the path to a local socket file, which would cause
the HTTP connection to fail.
This commit adds additional validation of the value of the DOCKER_HOST
environment variable to determine whether it is a remote address or
a local socket file and create the appropriate connection type.
Fixes gh-21173
Previously, a race between the server starting to reject requests
on a kept-alive connection and the request reaching the blocking
servlet could result in a response never being sent.
This commit updates the test to disable blocking once graceful
shutdown with an in-flight request has being. Awaitility is then used
to make a request on an idle kept-alive connection until it fails
due to the connection reset. This may not happen immediately due to
the aforementioned race.
Prior to this commit, details about an exception would get dropped when
the management context was separate from the application context and
an actuator endpoint threw a binding exception.
This commit adds some logic to capture the exception so the management
context error handlers can add the appropriate attributes to the error
response.
Fixes gh-21036
This commit improves the backward-compatibility of the ErrorAttributes
interfaces by providing a default implementation of a new method. It
also encapsulates several parameters that control the inclusion or
exclusion of error attributes into a new ErrorAttributeOptions type to
make it easier and less intrusive to add additional options in the
future. This encapsulation also makes the handling of the
includeException option more similar to other options.
Fixes gh-21324
Update `SpringBootContextLoader` to both add `spring.profiles.active`
properties and to directly call `Environment.setActiveProfiles`.
The additional `setActiveProfiles` call prevents `AbstractEnvironment`
from accidentally loading `spring.profiles.active` properties directly
when `doGetActiveProfiles` is called.
Directly setting active profiles has only become necessary since we
started adding properties using the square bracket notation. Previously
we added a comma-separated list which would be picked up by both the
`AbstractEnvironment` and the `ConfigurationFileApplicationListener`.
Closes gh-21302
Prior to this commit, the build tool plugins set the environment
variable BP_JAVA_VERSION when invoking the CNB builder to set the
version of the JDK/JRE that the builder should use in the created
image.
With CNB API 0.3, the convention changed the name of this environment
variable to BP_JVM_VERSION. This commit updates the build tool
plugins to match the newer convention.
See gh-21273
This commit modifies the buildpack platform invocation logic used by
the build plugins to invoke the single creator lifecycle introduced in
the CNB API 0.3, instead of invoking discrete lifecycle phases
separately. It also removes support for CNB API 0.2.
Fixes gh-21273
Add a `ConfigurationPropertyCaching` utility interface that can be
used to control the property source caching.
Prior to this commit, a `ConfigurationPropertySource` that was backed
by a mutable `EnumerablePropertySource` would need to call the
`getPropertyNames()` method each time a property was accessed. Since
this this operation can be expensive, we now provide a way to cache
the results for a specific length of time.
This commit also improves the performance of immutable property sources
by limiting the number of candidates that need to be searched.
Previously, all mapped names would be enumerated. Now, mappings are
grouped by `ConfigurationPropertyName`. This is especially helpful when
the `ConfigurationPropertyName` isn't mapped at all since the hash based
map lookup will be very fast and the resulting mappings will be empty.
Closes gh-20625
Provide a hashcode implementation for `ConfigurationPropertyName` so
that instances can be stored in Map without them all ending up in the
same bucket.
See gh-20625
Prior to this commit, the property was a Boolean with a null default.
If it was explicitly set by the user, a context customizer would use
that value to set it on the context. However, if it was not set, the default
wouldn't be tomcat's default but `false` because it was explicitly set to
`false` in `TomcatServletWebServerFactory`. This commit defaults the property
itself to `false` so that the default is more obvious to the user.

The warnings will be addressed by gh-20759. CreateBootStartScripts

Previously, unlike embedded Jetty, Netty, and Tomcat, Undertow would
not stop when one of its worker threads was in use. This meant that a
a long-running or stalled request could prevent the application from
shutting down in response to SIGTERM or SIGINT, and SIGTERM would be
required to get the process to exit.
This commit updates the factories for the reactive and servlet
Undertow web server factories to configure Undertow to use a 0ms
shutdown timeout. This aligns it with the behaviour of Jetty, Netty,
and Tomcat. Tests have been introduced to verify the behaviour across
the reactive and servlet variants of all four supported embedded web
servers.
Fixes gh-21319
Add converter support for `javax.time.Period` including:
String -> Period

Update the `isAncestorOf` method of SpringConfigurationPropertySources
so that legacy names are considered for the system environment.
Prior to this commit, binding a property such as `my.camelCase.prop`

the system environment.

This commit restricts how wildcards can be used in search
locations for property files. If a search location contains
a pattern, there must be only one '*' and the location should
end with a '*/'. For search locations that specify the file
name, the pattern should end with '*/<filename>'.
The list of files read from wildcard locations are now sorted
alphabetically according to the absolute path of the file.
Closes gh-21217
Prior to this commit, there was a property server.error.include-details
that allowed configuration of the message and errors attributes in a
server error response.
This commit separates the control of the message and errors attributes
into two separate properties named server.error.include-message and
server.error.include-binding-errors. When the message attribute is
excluded from a servlet response, the value is changed from a
hard-coded text value to an empty value.

This commit introduces a CookieSerializerCustomizer callback that
allows the customization of the auto-configured
DefaultCookieSerializer bean. This is particularly useful for
configuring cookie serializer's capabilities, such as SameSite, that
are not supported by the Servlet API and therefore not exposed via
server.servlet.session.cookie.* properties.

This commit changes the default builder image from
`cloudfoundry/cnb:bionic-platform-api-0.2` to
`gcr.io/paketo-buildpacks/builder:base-platform-api-0.3`. It also
uses a `paketo-buildpacks/builder` image instead of a
`cloudfoundry/cnb` image to test compatibility with lifecycle v2
and uses paketo naming instead of cloudfoundry when mocking builder
interactions.
Some adjustments to lifecycle phases were also made to align more
closely with the pack CLI.
Fixes gh-21066
This commit adds a new configuration property for configuring the

Previously, only root auto-configuration classes could be excluded
eagerly via an AutoConfigurationImportFilter. Any configuration class
loaded as a result of processing a particular auto-configuration were
parsed and checked as usual.
This commit makes use of the `getExclusionFilter` callback to expand
this filter to all candidates that are considered. The annotation
processor has also be expanded to generate metadata for non-root
configuration classes.

Prior to this commit, there was a cycle between `StatusAggregator` and

This commit turns the static field of the `StatusAggregator` interface
into a static method to avoid this problem.

This commit upgrades to RSocket 1.0.0-RC7.

Update `JarFile` so that `super.close()` is called early so that the

directly on the underlying `RandomAccessDataFile`, it should be safe
to close immediately.
Closes gh-21177
Previously, the developmentOnly configuration, typically used for
Devtools, had to be declared manually. The BootJar and BootWar tasks
then had a property, excludeDevtools, that could be used to control
whether or not Devtools would be excluded from the executable archive.
This commit updates the reaction to the Java plugin being applied to
automatically create the developmentOnly configuration. The classpaths
of bootJar and bootWar are then configured not to include the contents
of the developmentOnly configuration. As a result of this, the
excludeDevtools property is no longer needed and has been deprecated.
Its default has also been changed from true to false to make it easy
to opt in to Devtools, when configured as a development-only
dependency, being included in executable jars and wars by adding
developmentOnly to the classpath of the archive task.
Closes gh-16599
This commit removes the support for Reactor Netty metrics since it
seems that Spring Boot should not use this feature:
* HTTP metrics are already covered by WebFlux
* TCP metrics are only meant to TCP server/clients
* allocator metrics are already provided by Netty and there is
no specific API to enable them here.
Closes gh-19388
This commit enables the production of TCP and buffer allocator metrics
for Reactor Netty, client and server.
When applications use auto-configured server
(`NettyReactiveWebServerFactory`) and client (through
`WebClient.Builder`) instances, metrics will be enabled.
Note that HTTP metrics are not enabled here, since similar metrics are
already produced at the WebFlux level. Also, to avoid cardinality
explosion of metrics (through the URI tag), Reactor Netty offers
configurable infrastructure to deduplicate URI tags by turning expanded
URI instances into templated URIs. This is not targeted for Spring
usage.
Closes gh-19388
This new customizer-like interface make it possible to configure the
Reactor Netty `HttpClient` that is going to be used by the
`WebClient.Builder` provided by Spring Boot.

Starting the CouchbaseContainer fails intermittently when creation
of the primary index for the bucket fails with a read timeout. The
test doesn't require a primary index for the bucket so this commit
disables it creation in the hope that it will help to stabilise the
test.
Previously, DefaultResourceLoader instances were created using the
default constructor. This causes the resource loader to capture the
TCCL that was in place at that time. This can lead to a class loader
leak if the resource loader is referenced directly or indirectly from
a static field of a class loaded by a different class loader.
This commit updates the creation of DefaultResourceLoader instances
in main code so that the resource load will use the class loader of
the creating class. In almost all cases this will be the same class
loader as was the thread context class loader that was being captured
so the change in behavior is minimal. Crucially, it will still address
the situation where the TCCL was different.
Note the DevTools' ApplicationContextResourceLoader has been updated
to explicitly use the TCCL. This ensures that it uses the restart
class loader which is required for DevTools to function correctly.

Refactor `PortInUseException` logic to a single place and refine when
the exception is thrown.
Prior to this commit, we assumed that a `BindException` was only thrown
when the port was in use. In fact, it's possible that the exception
could be thrown because the requested address "could not be assigned".
We now only throw a `PortInUserException` if the `BindException` message
includes the phrase "in use".
Fixes gh-21101
This commit removes changes the timestamp used when writing the
classpath and layers index files in the Gradle plugin to be the
current timestamp unless `preserveFileTimestamps=true`. It also
polishes some duplication in the handling of entry attributes
when creating the fat archive and adds a test to verify that
the Gradle plugin uses the same fixed timestamp constant as
Gradle uses internally.
See gh-21005
Prior to this commit, when the Maven plugin copied
spring-boot-loader.jar to a repackaged archive the timestamps of class
files were preserved but the timestamps of directories were not
preserved. This resulted in the directories having a current timestamp.
This commit copies the directory timestamps from spring-boot-loader.jar
to the repackaged archive and adds tests to verify the proper
behavior.
See gh-20927
Update `JarURLConnection` to ensure that when connections are opened
a new copy of the JarFile is provided.
Prior to this commit, a single `JarFile` instance was shared which meant
that it could be accidental closed if accessed via
`JarURLConnection.getJarFile()`. If the underlying jar file is closed
then it's possible for a `NoClassDefFoundError` to be thrown if running
on JDK 11 with an active `SecurityManager`.
