Restructure actuator packages to improve structure. The following
changes have been made:
- Separate actuator and actuator auto-configuration into different
modules.
- Move endpoint code into `spring-boot-actuator`.
- Move `Endpoint` implementations from a single package into
technology specific packages.
- Move `HealthIndicator` implementations from a single package into
technology specific packages.
- As much as possible attempt to mirror the `spring-boot` package
structure and class naming in `spring-boot-actuator` and
`spring-boot-actuator-autoconfigure`.
- Move `DataSourceBuilder` and DataSource meta-data support from
`spring-boot-actuator` to `spring-boot`.
Fixes gh-10261
This commit introduces a "ReactiveHealthIndicator" contract that can be
implemented for health checks against a reactive API.
When running in a WebFlux-based web app, the health and status endpoints
transparently use this in a WebFlux-based application and regular
HealthIndicator are executed on the elastic scheduler.
When running in a Servlet-based web app, the endpoints includes and
adapts available ReactiveHealthIndicators automatically
Closes gh-7972
This commit migrates the Actuator onto the new endpoint infrastruture.
In addition to the existing support for accessing the endpoints via
JMX and HTTP using Spring MVC, support for access via HTTP using
Jersey and WebFlux has been added. This includes using a separate
management port where we now spin up an additional, appropriately
configured servlet or reactive web server to expose the management
context on a different HTTP port to the main application.
Closes gh-2921

Remove test-jar artifacts from Maven projects and relocate classes. The
majority of utilities now live in the `spring-boot-testsupport` module.
This update will help us to deploy artifacts using the standard Maven
deploy plugin in the future (which doesn't support the filtering of
individual artifacts).
Fixes gh-9493
Dependency management for the `HikariCP-java6` dependency is no longer
needed since Java 6 is no longer supported by Spring Boot.
The HikariDriverConfigurationFailureAnalyzer has been updated with the
current message thrown by HikariCP in this failure scenario.
Closes gh-8147
Add an annotation processor that generates properties files for certain
auto-configuration class annotations. Currently attribute values from
@AutoConfigureOrder, @AutoConfigureBefore, @AutoConfigureAfter and
@ConditionalOnClass annotations are stored.
The properties file will allow optimizations to be added in the
`spring-boot-autoconfigure` project. Primarily by removing the need
to ASM parse as many `.class` files.
See gh-7573
Update Spring Integration metrics support since Spring Integration
`4.3.6`+ no longer needs `spring-integration-jmx` enable
`MessageChannel`, `MessageHandler` and `MessageSource` metrics.
- Add `IntegrationManagementConfiguration` conditional auto-configuration
to provide `@EnableIntegrationManagement` when JMX is `enabled` or there
is no `IntegrationManagementConfigurer.MANAGEMENT_CONFIGURER_NAME` bean.
By default this bean doesn't exist and you explicitly should declare it
(e.g. via `@EnableIntegrationManagement`) if you would like to collect
metrics. At the same time Spring Integration enables it when JMX
management is present (that is a purpose of that new
`IntegrationManagementConfiguration`)
- Change `SpringIntegrationMetricReader` to read metrics from the
`IntegrationManagementConfigurer`, not `IntegrationMBeanExporter`
- Change `PublicMetricsAutoConfiguration` to register
`IntegrationManagementConfigurer.MANAGEMENT_CONFIGURER_NAME` bean if
not present. Since we are here in `actuator`, therefore we are
interested in the metrics for SI as well.
- Since we don't need JMX for the metrics any more, remove SI-JMX
dependency from the `spring-boot-starter-integration`.
- Remove `IntegrationManagementConfiguration` modification from the
`integrationMbeanExporter()`, since that looks like mutation of an
external object, when end-user would prefer their own options.
Therefore we don't need `ObjectProvider<IntegrationManagementConfigurer>`, too
- Add missed `MessageSourceMetrics` gathering for the
`SpringIntegrationMetricReader`
Closes gh-7722
This commit enables compatibility build against Spring Framework 5.
The Velocity and Guava support that are deprecated in the 1.x line have
been removed and few other classes contain minor change to comply to non
backward compatible changes in Spring Framework 5.
This commit also switches the required java version to 8.
Closes gh-6977
Previously, when access logging was enabled and the management server
was running on a separate port, both the main server and the management
server would write their access logs to the same file. Having two
separate containers writing to the same file could cause problems such
as causing log rotation to break.
This commit updates the actuator so that when the management server is
running on a separate port (and therefore using a separate container)
it prepends management_ to the access log prefix so that the main
server and the management server write their access logs to separate
files in the same directory.
Closes gh-6618
This commit changes the default version of Tomcat to 8.5.3 while
also retaining support for Tomcat 8.0 and 7.0. The main difference
in 8.5 is that the ServerSocketFactory abstraction that allowed the
TrustStore and KeyStore to be configured programatically no longer
exists. This logic has been replaced with the use of a custom URL
protocol (springbootssl) that provides access to the key store and
trust store of an SslStoreProvider. In addition to working with 8.5,
this approach has the advantage of also working with 8.0 and 7.0.
Closes gh-6164
This commit adds a Jest-based health indicator for ElasticSearch. If both
Jest and the Spring Data are available, the latter takes precedence as it
provides more information.
Closes gh-3178
