Refine the package restructure started in 91ccc23462 to help provide
a solid foundation for code snippets. This commit renames many of the
classes so that they no longer end in `Example`. It also removes some
of the inner types that were previously used. Many tag comments have
also been moved to ensure that `import` statements are available in
the docs.
Closes gh-25089
Restructure the packages in `spring-boot-docs` so that they mirror
the documentation sections. There are now three main packages:
`springbootfeatures`, `productionreadyfeatures` and `howto`. Each
of the main packages has a subpackage named after the section headings.
Example code now uses consistent `// tag::` names and imports are
applied using `[tag=*]` whenever possible.
Test snippets have been moved to `src/main/java` so that only a single
import attribute needs to be defined.
Closes gh-25089
Previously, Quartz could be configured with a specific DataSource
using `@QuartzDataSource` but it was not possible to configure a
Quartz-specific transaction manager. This could result in the
different DataSources being used by Quartz itself and Quart'z
DataSourceTransactionManager.
This commit introduces a new qualifier, `@QuartzTransactionManager`,
that can be used to avoid the above-described problem. Any
`@QuartzTransactionManager`-annotated bean will be used by the
Quartz auto-configure configuration instead of the application's main
`TransactionManager`. If no such qualified bean is present, the
application's main TransactionManager, if any, will be used as before.
Fixes gh-20184
This commit removes `<version>` from the Maven Plugin documentation
where it makes sense so that versions aren't hardcoded unnecessarily.
Rather, a plugin or dependency management should be in place so those
are not needed.
Closes gh-23909
Prior to this commit, the how-to documentation would say that Spring
Boot does not support the h2c protocol. While it's not supported
out-of-the-box with a configuration property, this protocol can still be
configured using server customizers.
This commit documents, with code snippets, the server customizers one
should use to configure the h2c protocol in an application - for each
supported server.
Closes gh-21997
This commit rework the tip on locating templates when running the app
in the IDE. Using classpath* should not change anything as this won't
make a difference without a pattern in the path.
Closes gh-23068
Prior to this commit, Actuator would sanitize properties values when
serializing them on the dedicated endpoint. Keys like "password" or
"secret" are entirely sanitized, but other keys like "uri" or "address"
are considered as URI types and only the password part of the user info
is sanitized.
This commit fixes the sanitization process where lists of such URI types
would not match the first entries of the list since they're starting
with `'['`. This commit improves the regexp matching process to sanitize
all URIs within a collection.
The documentation is also updated to better underline the processing
difference between complete sanitization and selective sanitization for
URIs.
Fixes gh-23037
With the upgrade to the new Couchbase SDK and the related changes in
Spring Data Couchbase, CacheManagerCustomizer can no longer be used to
customize the Couchbase cache manager as it is an immutable class.
This commit introduces a dedicated callback for the
CouchbaseCacheManagerBuilder that is used by the auto-configuration and
update the documentation to refer to it with a sample usage.
Closes gh-22573
This commit adapts the auto-configuration for the new core r2dbc support
in Spring Framework and provides auto-configuration for
R2dbcEntityOperations.
Closes gh-22708
Previously, the configuration property table generation was reading
both the main metadata and the additional metadata from each project.
This was unnecessary as the annotation processor will have already
merged the additional metadata into the main metadata before writing
it to disk. Processing both the main and additional metadata led to
a clash as the metadata overlapped. When the entry in the additional
metadata won the clash, the resulting entry in the configuration
property table would lose any details that aren't contained in the
additional metadata.
This commit updates the property table generation code to only use
the main metadata files.
Fixes gh-21131
Improve "@ConfigurationProperties vs. @Value" documentation with the
recommendation that kebab-case is used with the `@Value` annotation.
Closes gh-20507
When using constructor binding, if no properties are bound to
a nested property, the top-level instance will be created with a
null value for the nested property.
This commit introduces support for an empty `@DefaultValue` which
indicates that an instance of the nested property must be created
even if nothing is bound to it. It honors any `@DefaultValue`
annotations that the nested property might have in its constructor.
Closes gh-18917
This commit adds a section to the reference guide on how to initialize
a database using R2DBC. 2 smoke tests are also added to validate this
behaviour with Flyway and Liquibase.
Closes gh-20742
`compileJava.dependsOn(processResources)` is not enough to ensure the
correct behavior. Using `dependsOn` only affects the execution order
(`processResources` before `compileJava`) but not the up-to-date check
of `compileJava`. After modifying
`META-INF/additional-spring-configuration-metadata.json`, the
`processResouces` task will considered out-of-date and will be
re-executed, but after that `compileJava` will still be considered
up-to-date which causes the changes not to be merged into
`META-INF/spring-configuration-metadata.json`
With this change the up-do-date check of `compileJava` is affected,
too. Therefore, it will correctly re-execute the
configuration-processor when
`META-INF/additional-spring-configuration-metadata.json` was changed.

This commit movers the auto-configuration of RabbitTemplate to a
dedicated class that can be reused to create additional template with
similar settings.

This commit migrates JobLauncherCommandLineRunner to an
ApplicationRunner implementation. The latter allows to parse option
arguments (i.e. `--spring.something=value`) and makes it easy to ignore
arguments that are not meant to be passed to batch jobs.
Closes gh-19442
In general we do not recommend using @PropertySource due to them being
added to the environment too late for auto-configuration to use them. This
commit updates the documentation to mention them in the list of external
sources along with a note.
Closes gh-18900
Previously, our Gradle plugin was not tested against Gradle 6.0,
a number of deprecation warnings were output when using the plugin
with Gradle 6, and some functionality related to the application
plugin did not work as expected.
This commit tests the plugin against Gradle 6. It also avoids calling
deprecated APIs. The plugin is compatibile against Gradle 4.10 where
the deprecated APIs' replacements are not available so reflection is
used to call the replcaements. Lastly, the way in which the base name
of the boot distribution that is created when the application plugin
is applied has been modified to ensure that it is effective when using
Gradle 6.
Closes gh-18663
Previously, the documentation did not provide any guidance on using
Jersey alongside Spring MVC or any other web framework.
This improves the documentation in two ways:
1. It notes that, in the presence of both Jersey and Spring MVC, the
Actuator will prefer Spring MVC for exposing HTTP endpoints.
2. It adds a how-to describing how to configure Jersey to forward
requests for which it has no handler on to the rest of the filter
chain. When Spring MVC is the other framework, this allows them to
be handled by its dispatcher servlet.
Closes gh-17523
This commit is a continuation of the work done in 987a5f81. In
addition to developers and licenses that are covered in the earlier
commit, a number of other settings are still inherited from the
starter parent. This commit updates the documentation to show them
being overridden as well.
Closes gh-18532
Publishing to Maven Central requires spring-boot-starter-parent to
declare its license and developers. When a user then uses
spring-boot-starter-parent as their project's parent, these values
are inherited and this is almost certainly unwanted.
This commit updates the documentation to recommend and demonstrate
overriding the license and developers that are inherited from the
starter parent.
Closes gh-18532
Previously, the security risks and our recommendations on how to
mitigate them were not documented as clearly as they could have been.
This commit makes some changes to try to address this:
1. The security risk is now noted at the beginning of the section
2. The recommendation to use SSL is now documented more prominently
and an alternative recommendation to only use remote support on
a trusted network has been added.
3. The example secret has been removed to prevent copy and paste
4. A recommendation to use a secret that is unique and strong has been
added
Closes gh-18825
Previously, the endpoint tables in the documentation include an
"Enabled by default" column that listed whether or not an endpoint
was enabled by default. This resulted in some confusion as an endpoint
could be listed as being enabled by default but not actually be
enabled as the requirements for it being auto-configured has not been
met.
This commit removes the "Enabled by default" column and replaces it,
where needed, with some extra information in the "Description"
column that describes what is needed for the endpoint to be
auto-configured.
Closes gh-18633
In 2.2.0, @ConfigurationPropertiesScan was enabled by default.
Unfortunately, this had the unexpected side-effect of breaking
conditional enablement of a @ConfigurationProperties class via
@EnableConfigurationProperties if the @ConfigurationProperties class
was in a package covered by scanning.
This commit remove @ConfigurationPropertiesScan from
@SpringBootApplication so that it is no longer enabled by default.
2.1.x users who rely upon such conditional enablement of
@ConfigurationProperties classes can now upgrade to 2.2.x without
having to make any changes. Users who do not have such a need and are
in a position to use configuration properties scanning can now opt-in
by adding @ConfigurationPropertiesScan to their main application class
alongside @SpringBootApplication.
Closes gh-18674
This commit creates a new configuration property
`spring.codec.max-in-memory-size` which configures the maximum
amount of data to be buffered in memory by codecs (both client and
server).
This property has no default value - it will let Spring Framework handle
the default behavior, currently enforcing a 256KB for provided codecs.
Fixes gh-18828
Previously, the documentation did not describe how to combine
multiple security components when one component's
WebSecurityConfigurerAdapter or SecurityWebFilterChain would cause
the other components' beans of the same type to back off.
This commit adds a note that such cases should be handled by the user
defining their own WebSecurityConfigurerAdapter or
SecurityWebFilterChain that configures the use of all of the
components as required.
Closes gh-18507
Prior to this commit, all supported servers would share the same
configuration property `server.connection-timeout`. Unfortunately, in
many cases the behavior of this timeout changes depending on the server.
From actual connection setup timeout, to detecting and closing idle
connections, this property cannot be properly translated from one server
implementation to another.
This commit deprecates this configuration property and introduces server
specific properties:
* `server.jetty.connection-idle-timeout`
(Time that the connection can be idle before it is closed.)
* `server.netty.connection-timeout`
(Connection timeout of the Netty channel.)
* `server.tomcat.connection-timeout`
(Amount of time the connector will wait, after accepting a connection,
for the request URI line to be presented.)
* `server.undertow.no-request-timeout`
(Amount of time a connection can sit idle without processing a request,
before it is closed by the server.)
`server.connection-timeout` is now deprecated and will be removed in a
future release.
Fixes gh-18473
This commit adds a note to spring-boot-features.adoc to clarify that
using javadoc tags to format configuration property descriptions is not
supported.
See gh-18578
Update `@ConfigurationProperties` constructor binding support to only
apply when a `@ConstructorBinding` annotation is present on either the
type or the specific constructor to use.
Prior to this commit we didn't have a good way to tell when constructor
binding should be used vs regular autowiring.
For convenience, an `@ImmutableConfigurationProperties` meta-annotation
has also been added which is composed of `@ConfigurationProperties` and
`@ConstructorBinding`.
Closes gh-18469
Add a `show-components` property under `management.endpoint.health` and
`management.endpoint.health.group.<name>` that can be used to change
when components are displayed.
Prior to this commit it was only possible to set `show-details` which
offered an "all or nothing" approach to the resulting JSON. The new
switch allows component information to be displayed whilst still hiding
potentially sensitive details returned from the actual `HealthIndicator`.
