Main user-facing interface is still Counter/GaugeService but the
back end behind that has more options. The Default*Services write
metrics to a MetricWriter and there are some variants of that, and
also variants of MetricReader (basic read-only actions).
MetricRepository is now a combination of MetricReader, MetricWriter
and some more methods that make it a bit more repository like.
There is also a MultiMetricReader and a MultiMetricRepository for
the common case where metrics are stored in related (often open
ended) groups. Examples would be complex metrics like histograms
and "rich" metrics with averages and statistics attached (which
are both closed) and "field counters" which count the occurrences
of values of a particular named field or slot in an incoming message
(e.g. counting Twitter hastags, open ended).
In memory and redis implementations are provided for the repositories.
Generally speaking the in memory repository should be used as a
local buffer and then scheduled "exports" can be executed to copy
metric values accross to a remote repository for aggregation.
There is an Exporter interface to support this and a few implementations
dealing with different strategies for storing the results (singly or
grouped).
Codahale metrics are also supported through the MetricWriter interface.
Currently implemented through a naming convention (since Codahale has
a fixed object model this makes sense): metrics beginning with "histogram"
are Histograms, "timer" for Timers, "meter" for Meters etc.
Support for message driven metric consumption and production are provided
through a MetricWriterMessageHandler and a MessageChannelMetricWriter.
No support yet for pagination in the repositories, or for HATEOAS style
HTTP endpoints.
This commit adds a new starter named spring-boot-starter-shell-crsh and auto configuration support to embed a system shell within Spring Boot applications.
The embedded shell allows clients to connect via ssh or telnet to the Boot app and execute commands. Commands can be implemented and embedded with app.
For sample usage see spring-boot-samples-actuator.
To use a DataSource pool (Tomcat or DBCP) the user must supply a valid
driver class name *and* database URL. If both are supplied and the
driver class is not one of the embedded ones, then no default username
or password is provided.
Fixes gh-94
Previously, @Grab annotations would use Ivy to download the
dependencies with some of Ivy's known limitations being worked around
by GrapeEngineCustomizer.
This commit adds a GrapeEngine implementation that uses Aether,
the dependency resolution 'engine' used by Maven and Grails. To ensure
consistent behaviour with a Maven build, the Aether-powered dependency
resolution uses the dependency management configuration from the
spring-boot-starter-parent pom file.
The Git plugin was primarily being used to provide version information
that Boot's maven plugin can add into the MANIFEST.MF of the uber-jars
that it creates under the Spring-Boot-Commit-Id attribute.
This commit removes the Git plugin from Boot's own projects, but
leaves it in the spring-boot-starter-parent for use by Spring
Boot-based applications.
The attribute in the uber-jars' MANIFEST.MF has been replaced with a
Spring-Boot-Version attribute. The value of this attribute is the
implementation version of Repackager class's package.
- Look for JUnit test symbols, and add JUnit automatically
- Look for Spock test symbols, and add Spock automatically
- Based on what test libraries were used, invoke relevant embedded testers
and accumulate results
- Make it so that multiple testers can be invoked through a single 'test' command
- Print out total results and write out detailed trace errors in results.txt
- Update based on the new artifact resolution mechanism
- If RabbitTemplate is on the classpath, turn on autodetection.
- Create a RabbitTemplate, a Rabbit ConnectionFactory, and a RabbitAdmin is spring.rabbitmq.dynamic:true
- Enable some **spring.rabbitmq** properties like host, port, username, password, and dynamic
- Add tests to verify functionality
- Add Groovy CLI functionality. Base it on @EnableRabbitMessaging. Add spring-amqp to the path.
- Create rabbit.groovy test to prove it all works.
- Make Queue and TopicExchange top-level Spring beans in rabbit.groovy test script
* application.properties support for spring.jms and spring.activemq
* more tests to verify ActiveMQConnectionFactory pooling
* Groovy support and simple sample with activemq
* Groovy detection mechanism is @EnableJmsMessaging annotation
Adapted to changes in the API in Spring Data Commons which requires to pass in the current Environment into the AnnotationRepositoryConfigurationSource.
* Add ability to detect spring-jms on the path and create a JmsTemplate with
ActiveMQConnectionFactory
* Create tests showing autoconfigured JmsTemplate with ActiveMQ, but prove it
backs off if a separate ConnectionFactory exists.
* Add support to spring-boot-cli to that it detects JmsTemplate, DefaultMessageListenerContainer,
or SimpleMessageListenerContainer, and turns on autoconfiguration as well as
add proper @Grab's and import statements.
* Write a jms.groovy test showing proper CLI support
Simplify ActiveMQ configuration
Update ActiveMQ to 5.7.0
Create LiquibaseServiceLocatorInitializer to replace the standard
liquibase classpath scanning logic with SpringPackageScanClassResolver
which will work correctly in Spring Boot packaged executable JARs.
Issue: #55580628
Opinionated defaults for WebSockets:
* If spring-websocket is on the classpath and so is
the Tomcat WSci initializer then it is added to the context
* A DefaultSockJsService is added if none is present
* User has only to define @Beans of type WebSocketHandler with
name starting "/"
* Each one is converted to a SockJsHttpRequestHandler and
mapped to "/<beanName>/**"
Rework main build POM to be an aggregator pom that does not inherit
from any parent. Introduce new spring-boot-dependencies module to
act as a parent for both spring-boot-starter-parent and
spring-boot-parent.
