The DataSource health indicator uses `JdbcTemplate` behind the scenes
but nothing was checking that it is actually available.
`DataSourcesHealthIndicatorConfiguration` is now disabled if
`spring-jdbc` is not on the classpath.

Following the changes made to combines the /links and /hal endpoints
into a single /actuator endpoint, a web browser accessing /actuator
would receive a 406 response if HAL browser was not on the classpath.
This commit updates the /actuator main entry point so that it will
serve JSON to a web browser when HAL browser is not on the classpath.
The actuator's embedded documentation has also been updated to reflect
the recent changes.
Closes gh-3696
This commit provides a single endpoint, /actuator, that serves HTML
(the HAL browser) or JSON depending on the request’s accept header
that enables discovery of all of the actuator’s other endpoints.
When the management context path is configured, the /actuator endpoint
moves to the configured path, e.g. if the management context path is
set to /management, the actuator endpoint will be available from
/management.
Closes gh-3696
Update LinksMvcEndpoint and HalBrowserMvcEndpoint so that no longer try
to use the `/` context path. Links are now available from `/links` and
the HAL browser is available from `/hal`.
The actuator HAL browser now works with either WebJars or the Spring
Data version. It also now transforms the initial HTML so that the
form is pre-populated with `/links`.
When using Spring Data's HAL browser, the root includes a link to
`/links` with a rel of `actuator`.

ConfigurationPropertiesReportEndpoint parses the meta-data to inspect
entities that have potential cycles in them. The whole logic is based on
the lookup of `META-INF/spring-configuration-metadata.json` files on the
classpath. Unfortunately, the lookup instruction had a typo and did not
retrieve any file.
Surely that code was written with a clear intention in mind but it was
effectively dead code outside tests so it has been removed.
Closes gh-3310
Add a "management.health.defaults.enabled" property that controls whether
the default health indicators are enabled. This allow to disable them all
by default and still enable individual ones using their respective
specific property.
Closes gh-2298
Since `ManagementSecurityAutoConfiguration` is cnfiguring web-related
things, it has been renamed to `ManagementWebSecurityAutoConfiguration`.
Closes gh-2163
The default values of fields in @ConfigurationProperties classes are,
where possible, included in the configuration metadata. The default
values for the HAL and Links endpoints vary depending on other
configuration settings. As a result, including a default in the
metadata is misleading.
This commit removes the default assignment of "" to the path fields so
that no default value will be included in the metadata.
Closes gh-3567
Various areas of the code expect the management's context path to not
contain any trailing slash but nothing is enforcing it. We now make sure
to remove any trailing slash, including the one for '/' and make that
explicit via the Javadoc of the getter.
Fixes gh-3553
Previously, an item could only have a 'deprecated' boolean flag to
indicate that the property is deprecated. It is desirable to provide an
additional description for the deprecation as well as the name of the
property to use instead.
The `deprecated` boolean flag is now supported. Instead, a `deprecated`
object can be specified with two optional attributes: `reason` to provide
an explanation for the deprecation and `replacement` to refer to the
property that should be used instead. If none of them is present, an
empty deprecation object should be set.
For backward compatibility, the `deprecated` field is still set.
Deprecation information can only set via manual meta-data.
Closes gh-3449
When Spring Data REST is owning the home page it has its own
HandlerMapping with a fix (relatively) low priority. The /links
endpoint wants to own the home page as well, and our handler mapping
has a high priority for good reasons. This change addresses the
issue by checking if Spring Data REST is configured and if
the management context path (or more specifically, the links
endpoint) is the same as the home page.
Fixes gh-3486
When Spring Security sends 302 responses to a login page we don't get
any information about the request matching in Spring MVC. Consequently
apps can end up with a lot of counter.status.302.* metrics (where
"*" can be whatever the user sent).
This change treats 3xx the same as 4xx (if it is unmapped it just gets
added to a metric called "unmapped" instead of using the actual request
path).
Fixes gh-2563
