Use `spring-javaformat` to format and check code. Code formatting can
now be applied using the `spring-javaformat-maven-plugin` from the
command line. Existing checkstyle rules have also been replaced and
the CONTRIBUTING.adoc file has been updated.
Closes gh-13255
Previously, remote DevTools only correctly supported modifying
existing classes. New classes that were added would be missed, and
deleted classes could cause a failure as they would be found by
component scanning but hidden by RestartClassLoader.
This commit introduces a DevTools-specific ResourcePatternResolver
that is installed as the application context's resource loader. This
custom resolver is aware of the files that have been added and
deleted and modifies the result returned from getResource and
getResources accordingly.
New intergration tests have been introduced to verify DevTools'
behaviour. The tests cover four scenarios:
- Adding a new controller
- Removing an existing controller
- Adding a request mapping to a controller
- Removing a request mapping from a controller
These four scenarios are tested with:
- DevTools updating a local application
- DevTools updating a remote application packaged in a jar file
- DevTools updating a remote application that's been exploded
Closes gh-7379
Update `checkstyle.xml` to use fully qualified class names. This reduces
the number of warning log messages when running `mvn -X` and should also
be slightly faster.
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
Rework the new testing support so that @SpringApplicationTest can be
used for standard integration tests, web integration tests with a
mock Servlet environment and web integration tests with an embedded
servlet container. This means that it a replacement for 1.3's
@IntegrationTest and @WebIntegrationTest and allows all
SpringApplication testing to be configured using a common annotation.
The old @IntegrationTest and @WebIntegrationTest along with their
supporting classes have been reinstated to their previous form (while
remaining deprecated). This should ensure that they continue to work
in 1.4 exactly as they did in 1.3 giving users a smooth path to
@SpringApplicationTest.

Eclipse Mars has a formatter bug (#479291) that sometimes adds
additional whitespace on annotations. Until it's fixed we need to relax
the `ParenPad` checkstyle rule.
