Prior to this commit, EndpointWebMvcAutoConfiguration would start a
child context if the management port was different to the server port
and the application context was a web application context. This caused
two problems:
If a user built an executable war and configured the management port so
that it was different to the server port, their application would run
successfully when launched with java -jar, but it would fail when
deployed to Tomcat as an attempt would be made to start embedded Tomcat.
Secondly, if a user ran a test annotated with @WebAppConfiguration the
main embedded Tomcat instance would not be started, but the child
context would trigger the creation of a Tomcat instance listening on the
configured management port. This is unexpected as @WebIntegrationTest
or @IntegrationTest and @WebAppConfiguration should be required to have
the test trigger full startup of the application and listen on the
configured ports.
This commit updates EndpointWebMvcAutoConfiguration so that it will only
start a child context when the management port is different to the
server port and the EmbeddedWebApplicationContext has an embedded
servlet container. This resolves the two problems described above as
there will be no embedded servlet container when deployed to a
standalone container or when a test is run without @IntegrationTest.

Previously, when multiple cache managers had a cache with the same name,
the prefix for the first cache that was processed would not include its
cache manager’s name, but all subsequent prefixes would include the
cache manager’s name. This was inconsistent, and due to the cache
managers being unordered, the prefixing was not deterministic.
This commit updates the prefixing logic so that when there is a clash,
all of the affected prefixes will include the name of the cache manager.
For example, with cache managers named first and second and each
with a cache named users, the prefixes will be cache.first_users and
cache.second_users rather than cache.users and
cache.{first|second}_users.

multipleCacheManagers fails on the CI server but does not fail
locally. This commit updates assertMetrics to include information
about the actual metrics so it's clear why the expectation was not
met.
Add an abstraction that provides a standard manner to retrieve a
statistics snapshot of a cache.
Specific implementations for JSR-107, ehcache, hazelcast, guava and
concurrent map are provided. At the moment the size of the cache and
the hit/miss ratios are recorded. Cache metrics are exposed via the
`cache.` prefix followed by the name of the cache. In case of conflict,
the name of the cache manager is added as a qualifier.
It is possible to easily register a new CacheStatisticsProvider for an
unsupported cache system and the CacheStatistics object itself can be
extended to provide additional metrics.

Previously, if a call to doFilter in MetricFilter failed (i.e. it threw
an exception), it would be handled as if it had a response status of
200. This is because the servlet container was yet to handle the
exception and set the response status to 500.
This commit updates MetricFilter to assume that an exception thrown from
doFilter will result in a response with a status of 500. Strictly
speaking, even though the filter has highest precedence and will
therefore run last on the way back out, this may not always be the case.
For example, a custom Tomcat Valve could handle the exception and result
in a 200 response but that’s an edge case that’s into shooting yourself
in the foot territory.

- added setIndices to ElasticsearchHealthIndicatorProperties to enable
setting the indices property from configuration files
- Elasticsearch cannot handle "null" if the health of all indices should
be checked; use "_all" instead

This commit updates Spring Boot to use Spring Security 4. As a result
of this, the coordinates of Thmyeleaf's Spring Security extra, for
which dependency management and auto-configuration is provided, have
been updated to the Spring Security 4 variant.
Closes gh-2727
- Nest the configuration class in HealthIndicatorAutoConfiguration,
bringing it into line with the other health indicator configuration
classes
- Include the statistics from the response in the health’s details
- Map YELLOW to UP rather than UNKNOWN as it indicates that the cluster
is running but that “the primary shard is allocated but replicas are
not” [1]. The details can be used to determine the precise state of
the cluster.
- Add a property to configure the time that the health indicator will
wait to receive a response from the cluster
- Document the configuration properties
- Update the tests to cover the updated functionality

This commit improves upon the changes made in a8bf9d3 by adding
support for relaxed binding of the endpoints.enabled and
endpoints.<name>.enabled properties. This is achieved by replacing
use of @ConditionalOnExpression (which does not support relaxed
binding) with a custom condition implementation that uses
RelaxedPropertyResolver.
Closes gh-2767
Previously, only invocations of /metricName/ would honour the enabled
property and return a not found (404) response. For endpoints which
support nested paths, access to /metricName/foo would ignore the enabled
flag and return an OK (200) response. Furthermore, there was a comment
in EndpointMvcAdapter that suggested that an endpoint shouldn’t be
called when it is disabled, however this was not the case.
This commit updates EndpointWebMvcAutoConfiguration and
JolokiaAutoConfiguration to only register their MvcEndpoint beans if
the underlying endpoint is enabled. This means that an
EndpointMvcAdapter should not be called if its delegate is disabled,
making the comment described above accurate.
The check for the delegate being enabled has been retained so as not to
rely upon the auto-configurations’ behaviour. The methods which handle
nested paths (MetricsMvcEndpoint.value() and
EnvironmentMvcEndpoint.value()) have been updated to add the same check
for the enablement of their delegate.
Fixes gh-2767
Prior to this commit, every EndpointMBean used its own ObjectMapper.
Each of these ObjectMappers was created using new ObjectMapper() with
no opportunity for configuration.
This commit uses the ObjectMapper from the application context and
shares it among all EndpointMBeans. This gives the user control over
the ObjectMapper’s configuration using spring.jackson.* properties,
their own Jackson2ObjectMapperBuilder bean, etc. In the absence of an
ObjectMapper in the application context a single ObjectMapper is
instantiated and is used by all EndpointMBeans instead.
To allow the ObjectMapper to be shared, a number of constructors have
been overloaded to also take the ObjectMapper as a parameter. In these
cases the old constructor has been preserved for backwards compatibility
but has been deprecated.
Closes gh-2393
Prior to this commit, the auto-configuration report (both in its logged
form and the actuator endpoint) listed the positive and negative matches
but did not list the classes, if any, that the user had excluded.
This commit updates the logged report and the actuator endpoint to
expose a list of the excluded class names configured via the exclude
attribute on @EnableAutoConfiguration.

Previously, disk health information only included the amount of free
space and the configured threshold. This commit adds the disk’s total
space.

NoClassDefFoundErrors which can occur when deploying to Google App
Engine.

Previously, the response from /health was not cached if the request
was secure, i.e. the user has authenticated, or the endpoint was
configured as not being sensitive.
The commit updates HealthMvcEndpoint to apply the caching logic
all the time. Users that do not want caching can disable it by
configuring the TTL with a value of zero.
