On CI, Cassandra running inside the Docker container sometimes fails
to start or the start times out. This has nothing to do with Boot so
we attempt to protect our tests from the flakiness of the container
by allowing 3 startup attempts.
This commit adds InvalidEndpointRequestException as a technology
agnostic way to signal that an endpoint request is invalid. When such
exception is thrown, the web layer translates that to a 400.
Rather than overriding the reason, this commit makes sure to reuse the
error infrastructure.
Closes gh-10618
Rename `spring-boot-configuration-analyzer` to
`spring-boot-deprecated-properties-support`.
Also renamed classes to match and polished some of the code.
See gh-11301
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
As explained in the "Split package compatibility" section of
https://blog.jetbrains.com/kotlin/2017/09/kotlin-1-2-beta-is-out/
kotlin-stdlib-jdk7 and kotlin-stdlib-jdk8 are the recommended
dependencies to use with Kotlin 1.2 for Java 9+ compatibility.
Closes gh-11716
Add `@ControllerEndpoint` and `@RestControllerEndpoint` annotations that
can be used to develop a Spring-only request mapped endpoint. Both
Spring MVC and Spring WebFlux are supported.
This feature is primarily for use when deeper Spring integration is
required or when existing Spring Boot 1.5 projects want to migrate to
Spring Boot 2.0 without re-writing existing endpoints. It comes at the
expense of portability, since such endpoints will be missing from
Jersey.
Fixes gh-10257
Create a `PathMappedEndpoint` interface that allows any `ExposedEndpoint`
to provide root path details. The `EndpointPathResolver` interface has
been renamed to `PathMapper` and is now only used during endpoint
discovery.
`EndpointPathProvider` has been replaced with `PathMappedEndpoints`
which simply finds relevant path mapped endpoints.
Fixes gh-10985
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.

Previously, the server was created with out an explicitly configured
address. This lead to it using any local address which will prefer
IPv6 (::0) if it's available. By contrast, the client was created
with a base URL that specified localhost as the host. This meant the
the client would prefer to connect to IPv4. Normally this wouldn't
cause a problem as nothing would be listening on the port in the IPv4
stack so the client would then connect to the server being tested
using the IPv6 stack. However, if another process was listening to the
port in the IPv4 stack, the client would connect to the wrong server.
This could lead to an unexpected 404 response (if the wrong server
was an HTTP server) or a hang if it was not.
There's a chance, although I think it's unlikely, that the problem
described above is the cause of gh-10569. I think it's unlikely as
the hang tracked by gh-10569 only occurs when running the WebFlux
endpoint integration tests using Reactor Netty. If it was the problem
described above, there's no reason that I can think of why we
wouldn't have also seen it with the Web MVC endpoint integration
tests.
As `validation-api` 2 is available by default, this commit adds the
integration test as a regular test case. The integration test is kept to
exercise what happens in a standard project.
See gh-11512
This commit prevents the default error view from rendering itself if the
response has been committed already. In this case, it is impossible to
change the HTTP response status and write a proper response - trying to
do so often results in a `IllegalStateException` since the response body
has already been written to.
Fixes gh-11580
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
This commit removes the use of the incubating PropertyState and
Provider API that was introduced in Gradle 4.0 and deprecated in
Gradle 4.3. A not-deprecated-but-still-incubating replacement was
introduced in Gradle 4.3. The short life of PropertyState and Provider
has made me wary of using an incubating Gradle API in our public API
as it may not be stable for long. Therefore, this commit does not move
to the replacement as it is incubating. Instead, it falls back to
using Gradle's convention mapping. This is internal API, but its use
is not part of our public API and I perceive the risk of using it to
be lower than using the deprecated and/or incubating API alternatives.
Closes gh-11640
Improve the structure of the response and include mappings from
WebFlux and Servlet and Filter registrations in addition to the
mappings from Spring MVC.
Closes gh-9979
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
Previously, a number of Actuator endpoints ignored a context hierarchy
or assumed that it would always be linear. This commit reworks the
affected endpoints so that the no longer assume a linear hierarchy.
A side-effect of a non-linear hierarchy is that there may be multiple
different beans with the same name (in a linear hierarchy, a bean
with the same name as one in an ancestor context, replaces that bean).
The affected endpoints have also been updated so that, when bean names
are used as keys, those keys are grouped by application context. This
prevents a bean in one context from accidentially overwriting a bean
in another context.
Closes gh-11019
Since type erasure can be fixed only when using
ParameterizedTypeReference based Java methods, TestRestTemplate
API documentation should be updated to specify which extensions
are subject to type erasure, and which are not.
Closes gh-11604
This commit updates DefaultErrorAttributes to handle
ResponseStatusException explicitly. This exception is used in a
WebFlux application to signal that the processing of the query has
failed with an HTTP status code and a reason phrase. The latter is now
properly mapped to the `message` attribute of the response body.
Closes gh-11614
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 commits improves the cache auto-configuration for Redis by looking
up a custom "RedisCacheConfiguration" bean that allows to take full
control over the `RedisCacheManager`.
Closes gh-11599
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 fixes the `responseCommitted` test in
`DefaultErrorWebExceptionHandlerIntegrationTests` and reworks the whole
test class to use the `ContextRunner` infrastructure.
Fixes gh-11519
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
As HibernateJpaConfiguration is package private, it is no longer
possible to extend the default Spring Boot configuration to apply
advanced settings. The most notable use case for this is the
customization of Hibernate properties using instance value vs. string
value that can be set using the "spring.jpa.properties" namespace.
This commit adds a HibernatePropertiesCustomizer callback interface that
can be implemented to tune Hibernate properties at will.
Closes gh-11211
I made a complete editing pass plus another pass to see where I could add more links, both within the document and to other parts of Spring. The result was a thorough edit (though I'm sure I missed things, purely due to the size of the thing).
