With this commit the state of a component or subsystem becomes a first-class citizen in Boot's application health support. HealthIndicators now return a Health instance with status and some contextual details.
An aggregation strategy has been introduced to aggregate several Health instances into one final application Health instance. Out of the box OrderedHealthAggregator can be configured to allow different ordering or a custom HealthAggregator bean can be registered.
We now have a much simpler DataSourceAutoConfiguration that binds to whatever
DataSource concrete type it finds at runtime. To be able to quickly switch between
Hikari and the other types of DataSource there's a minute shim for translating
the common properties (username, password, url, driverClassName), but actually
only url is different. The shim and also DataSource initialization is supported
through DataSourceProperties, but the other native properties get bound directly
through the concrete runtime type of the DataSource.
The /configprops endpoint works (and is exposed in the actuator sample).
Fixes gh-840, fixes gh-477, see also gh-808.
Since Spring supports gobal error handling through
@ControllerAdvice, it is quite easy to set up more meta-data
about an exception for the BasicErrorController. You need
to be careful not to swallow Security exceptions, and probably
others (optionally) so this feature needs a bit more work.
See gh-538
Spring Security doesn't know that Spring MVC maps /foo, /foo.json
and /foo/ all to the same handler. This change explicitly adds
suffixes to the actuator endpoint matchers so they are properly
protected.
Rename the RestTemplates to TestRestTemplate to help indicate that it's
primarily intended for testing. Also now extend RestTemplate to allow
direct use, rather than via factory methods.
Fixes gh-599
Remove README files that have been since been migrated to the reference
documentation. Also updated remaining markdown files to asciidoctor to
save having a mix of different formats.
Fixed gh-503
Makes them a lot more readable IMO, and also enables @Autowiring
from the context into the test case (sweeet). I added @DirtiesContext
to all of them as well to be on the safe side, but possbly that can be
optimized in some way as well.
The management.contextPath property should now be respected in a
secure application, whether or not the management.port is different.
Added some test cases in the sample to verify.
Fixes gh-469
Use org.springframework.boot instead of ${project.groupId}
groupId in order to make it easier to use spring-boot-samples
modules as a starting point for new projects.
