The cache abstraction is a core feature of the Spring Framework. Basic
features such as `@EnableCaching` are therefore available by default with
no extra dependencies necessary.
However, the actual cache adapters for JCache, Ehcache 2.x, Caffeine and
Guava are located in a separated module, `spring-context-support`. Spring
Boot provides that artifact via the `spring-boot-starter-cache` starter.
It is quite easy to "only" add the cache library dependencies and forget
about this extra dependencies since `@EnableCaching` is available by
default. This commit clarifies the role of the starer in each section so
that it is more obvious. We're already explaining this at the beginning
of the section but it seems that's not enough.

Add an explicit note that states that "spring.datasource.url" (or more
specifically "spring.datasource.class-name" that is inferred from the
former) is necessary to connect to a database. If the class-name isn't
specified, Spring Boot will attempt to auto-configure an embedded
database.
Closes gh-6907
This commit improves the startup error message so that it does not
reference `--debug` anymore. Such command-line switch only works when
the application is started using `java -jar`.
The error message now refers directly to a section of the documentation
that provides more details and links to more useful examples.

When extending `WebMvcConfigurerAdapter`, developers should always
declare those as `@Configuration` classes rather than `@Bean`s, which
can lead to dependency issues as described in #6853.

This commit adds `JdbcTemplateAutoConfiguration` to the list of auto-
configurations that are applied with `DataJpaTest`. This effectively
allows to inject a `JdbcTemplate` in any `@DataJpaTest` test.
Closes gh-6802
Rework commit 4a69755b to remove the need for the ApplicationInfo class.
The updated code now uses the auto-configuration class to compute a
default persistence unit root location
Closes gh-6635
Due to the layout format change in 1.4, Spring Framework is no longer
able to compute a default persistence unit root URL. If a Spring Boot 1.4
application has JPA but does not have any entity, the application started
from a fat jar now fails with a quite cryptic exception.
This commit introduces `ApplicationInfo` as a general replacement for
the `ApplicationArguments` and `Banner` singleton beans that
`SpringApplication` registers on startup. `ApplicationInfo` also defines
the detected "main" `Class` that can be used to compute a last resort
URL that makes sense.
If such bean is available, `EntityManagerFactoryBuilder` now sets the
default persistence unit root location, preventing Spring Framework to
attempt to resolve an unknown location. Note that in our case the
persistence unit root location is actually useless: given the way the
persistence unit is created, nothing actually uses it but Hibernate, as a
compliant JPA provider, has to make sure this setting is set to a valid
URL nevertheless.
Closes gh-6635
Switch `@AutoConfigureJsonTesters` to use regular `@Autowired` injection
for JSON testers. Prior to this commit JSON Tester fields were
initialized directly which caused IDE issues and was also a little
confusing.

The upgrade to Hibernate 5.2.0.Final has provide to be too
problematic to live with. It requires Java 8, is incompatible with
a number of other projects in the Hibernate ecosystem, and it's
unclear for how long it will be maintained. We'd previously used
Hibernate 5.1.0.Final but its maintenance is also unclear with
Hibernate 5.1.1.Final being more than 3 months overdue.
This commit drops back to Hibernate 5.0.9.Final. This has a few
advantages:
- It's Java 7 compatible
- It's had some time to mature and should be reasonably free of
regressions for those moving from 4.3.x
- It's used in both Wildfly and JBoss EAP so there's a fair chance
that it will continue to be maintained.
Closes gh-6198
This commit adds auto-configuration support for Jest, an HTTP client for
Elasticsearch. If Jest is present, a `JestClient` targeting a local
elasticsearch instance is auto-configured. Several properties from the
`spring.jest.*` namespace allows to tune the client.
Closes gh-6032
Add `WebMvcRegistrations` which can be used to provide custom
instances of `RequestMappingHandlerMapping`,
`RequestMappingHandlerAdapter` and `ExceptionHandlerExceptionResolver`.
Those instances are then used and processed by the Boot MVC
configuration.
Prior to this commit, developers could provide their custom instances
of MVC infrstructure components such as `RequestMappingHandlerMapping`
and `RequestMappingHandlerAdapter` only by using advanced configuration
strategies. Those advanced configurations involved subclassing
`WebMvcConfigurationSupport` which effectively turns off MVC
auto-configuration in Boot.
Fixes gh-5004
Closes gh-6100
As `@DataJpaTest` is meta-annotated with `@Transactional`, all data jpa
tests are transactional and rollback at the end of each test. It is
possible to tune that in many ways, including disabling the transaction
per test or per test class.
This commit improves the doc to explain those concepts.
Closes gh-5993
"Starter POM" is a confusing term as it implies the starter may be a
POM while it's actually a jar artifact like any other dependency. To
reduce the confusion (especially in the way such starter should be
declared in the build), the term Starter POM has been renamed to Starter.
Closes gh-5966
This commit removes the creation of a `@Primary` `OAuth2RestTemplate`
and updates the documentation accordingly.
Once #5507 is implemented we could revisit this area to provide a way for
users to easily create such a bean.
Closes gh-5202
Previously, Spring Session would be auto-configured by the mere presence
of Spring Session in the classpath. This was fragile as determining a
store type according to the environment could easily change when the
classpath of the project changes.
This commit makes the store-type property mandatory. If it is not set,
Spring Session is no longer auto-configured.
Closes gh-5838
Allow convention based status error pages. Static HTML or templates
can be used by placing the appropriately named file under a `/error`
folder. For example:
/src/main/resource/templates/error/404.ftl
or /src/main/resource/public/error/404.html
Pages can also be named after the status series (5xx or 4xx).
Fixes gh-2691
This commit introduces a new annotation, @AutoConfigureRestDocs,
which can be used to enable auto-configuration of Spring REST Docs.
The auto-configuration removes the need to use Spring REST Docs' JUnit
rule and will automatically configure MockMvc. Combined with the new
auto-configuration for MockMvc it allows a test class to be free of
boilerplate configuration:
@RunWith(SpringRunner.class)
@WebMvcTest
@AutoConfigureRestDocs(outputDir = "target/generated-snippets",
uriScheme = "https", uriHost = "api.example.com",
uriPort = 443)
public class ExampleDocumentationTests {
@Autowired
private MockMvc mvc;
@Test
public void documentIndex() {
// …
}
}
For more advanced customization a RestDocsMockMvcConfigurationCustomizer
bean can be used.
If a RestDocumentationResultHandler is found in the context, it will
be passed to the ConfigurableMockMvcBuilder's alwaysDo method as part
of its customization.
Closes gh-5563
This commit polihes the original Neo4j contribution in several areas.
Rather than providing the packages to scan, this commit rearranges the
`EntityScan` and `EntityScanRegistrar` so that the logic can be shared
for other components. If no package is provided, scanning now defaults to
the "auto-configured" package(s) and a `@NodeEntityScan` annotation
allows to override that.
The configuration has also been updated to detect the driver based on the
`uri` property. If the embedded driver is available we use that by
default. If it is not available, we're trying to connect to a Neo4j
server running on localhost. It is possible to disable the embedded mode
or set the `uri` parameter explicitly to deviate from these defaults.
The sample no longer relies on the embedded driver for licensing reason:
rather it expects an instance running on localhost (like other
data-related samples) and gracefully ignore any connection error. A
README has been added in the sample to further explain the available
options;
