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.
Closes gh-10595
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.
Fixes gh-10656
This commit removes the cleanup of the javax.validator.Validator that
can be created to validate @ConfigurationProperties binding as the
memory effect can no longer be reproduced.
Closes gh-10573
Starting with Hibernate 5.2.10, the JPA property
`hibernate.connection.provider_disables_autocommit` should be set to true
when the datasource has autocommit disabled in order to improve
performance.
See gh-9737
Update `Binder` so that Maps containing references to themselves may
be bound. The existing stack-overflow protection (required when binding
a bean to a non enumerable source) now only applies to bean properties.
Fixes gh-9801
