This commit simplifies the Jackson-related auto-configuration that’s
applied when Spring HATEOAS and Spring Data REST are on the classpath.
Previously, Boot used Jackson2HalModule to apply the HAL-related
ObjectMapper configuration to the context’s primary ObjectMapper. This
was to allow HAL-formatted responses to be sent for requests accepted
application/json (see gh-2147). This had the unwanted side-effect of
polluting the primary ObjectMapper with HAL-specific functionality.
Furthermore, Jackson2HalModule is an internal of Spring HATEOAS that
@olivergierke has asked us to avoid using.
This commit replaces the use of Jackson2HalModule with a new approach.
Now, the message converters of any RequestMappingHandlerAdapter beans
are examined and any TypeConstrainedMappingJackson2HttpMessageConverter
instances are modified to support application/json in addition to their
default support for application/hal+json. This behaviour can be disabled
by setting spring.hateoas.use-hal-as-default-json-media-type to false.
This property is named after Spring Data REST’s configuration option
which has the same effect when using Spring Data REST. The new property
replaces the old spring.hateoas.apply-to-primary-object-mapper property.
Previously, when Spring Data REST was on the classpath,
JacksonAutoConfiguration would be switched off resulting in the context
containing multiple ObjectMappers, none of which was primary.
This commit configures RepositoryRestMvcAutoConfiguration to run after
JacksonAutoConfiguration. This gives the latter a chance to create its
primary ObjectMapper before the former adds its ObjectMapper beans to
the context.
Previously, the actuator’s hypermedia support assumed that the
HttpMessageConverters bean would contain every HttpMessageConverter
being used by Spring MVC. When Spring HATEOAS is on the classpath this
isn’t the case as it post-processes RequestMappingHandlerAdapter beans
and adds a TypeConstrainedMappingJackson2HttpMessageConverter to them.
This wasn’t a problem in the past as the primary ObjectMapper, used by a
vanilla MappingJackson2HttpMessageConverter, was configured with Spring
HATEOAS’sJackson2HalModule. Now that this pollution has been tidied up
the assumption described above no longer holds true. MvcEndpointAdvice,
which adds links to the actuator’s json responses, has been updated
to look at the HttpMessageConverters of every
RequestMappingHandlerAdapter when it’s trying to find a converter to
use to write a response with additional hypermedia links.
Integration tests have been added to spring-boot-actuator to ensure
that the changes described above have not regressed the ability to
configure its json output using spring.jackson.* properties (see
gh-1729).
Closes gh-3891
Update DataSourceProperties exceptions to include a less misleading
message. Errors message now note that you may need to add an embedded
database to the classpath or active a profile to pickup specific
settings.
Fixes gh-4012
Update MetricExportAutoConfiguration to auto-configure statsd metrics
export when a `spring.metrics.export.statsd.host` property is set.
Closes gh-3719
Update `DevToolsProperties` to exclude `git.properties` files.
Prior to this commit any application configured to write `git.properties`
could trigger unexpected application restarts. The problem is particularly
prevalent when using Eclipse M2E in combination with the
`git-commit-id-plugin`.
Closes gh-3938
Relocate several auto-configuration classes to `...autoconfigure.data`
to make it clearer that they are Spring Data specific.
Also moved `EntityManagerFactoryBuilder` to `spring-boot` since it is
generally useful and doesn't need to be directly tied to the
auto-configuration module.
Fixes gh-4002
The parameter names module allows users of Java 8 that have compiled
their code with the -parameters option to avoid the name for
annotations to map the json onto constructor and method parameters
with the names of the parameters being used instead.
This commit adds auto-configuration for the module that will only
be enabled when running on Java 8.
Closes gh-3804
Previously, dev tools would restart the application when any .class
file changed. This included test classes. This commit updates the
default excludes to ignore any classes with a name that ends in
Test.class or Tests.class.
Closes gh-3900
For the character encoding filter to work, it's vital that it sets
the request's encoding before any other filters attempt to read the
request. This commit updates the order of
OrderedCharacterEncodingFilter to be HIGHEST_PRECEDENCE and improves
the existing test to check that the ordering is as required.
Closes gh-3912
The recommended usage for the java executable is:
java [-options] -jar jarfile [args...]
This commit updates the default launch script to match this recommended
usage by moving -jar to be the last option, after both the
disableJarChecking system property and any JAVA_OPTS.
Closes gh-3930
