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
Upgrade to Micrometer 1.0.0-rc.3 and refactor existing
auto-configuration to align with updated APIs.
Note that Spring MVC instrumentation has now changed from an interceptor
to a Filter.
See gh-10906
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 ensures that all errors handled by the
`DefaultErrorWebExceptionHandler` (Spring WebFlux error convetion
support) logs an error with request information and exception
stacktrace.
This is limited to errors that result in an HTTP 5xx error.
Exceptions that extend `ResponseStatusException` and set a non-5xx
status will not be logged.
Closes gh-10904
On WebSphere Liberty, the javax.validation package may be visible but
other javax.validation packages upon which it depends may not be
visible. This can lead to an incorrect assumption that the Bean
Validation API is available when, in fact, it is only partially
available.
Add an additional check for the availability of a class in the
javax.validation.bootstrap package to ensure that it's not just the
javax.validation package that's available.
Closes gh-10877
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
