Spring Cloud Bus links the nodes of a distributed system with a lightweight message
|
||||
broker. This broker can then be used to broadcast state changes (such as configuration
|
||||
changes) or other management instructions. A key idea is that the bus is like a
|
||||
distributed actuator for a Spring Boot application that is scaled out. However, it can
|
||||
also be used as a communication channel between apps. This project provides starters for
|
||||
either an AMQP broker or Kafka as the transport.

|

Spring Cloud Bus works by adding Spring Boot autconfiguration if it detects itself on the
|
||||
classpath. To enable the bus, add `spring-cloud-starter-bus-amqp` or
|
||||
`spring-cloud-starter-bus-kafka` to your dependency management. Spring Cloud takes care of
|
||||
the rest. Make sure the broker (RabbitMQ or Kafka) is available and configured. When
|
||||
running on localhost, you need not do anything. If you run remotely, use Spring Cloud
|
||||
Connectors or Spring Boot conventions to define the broker credentials, as shown in the
|
||||
following example for Rabbit:

username: user
|
||||
password: secret
|
||||
----
|
||||
|
||||
The bus currently supports sending messages to all nodes listening or all nodes for a
|
||||
particular service (as defined by Eureka). The `/bus/*` actuator namespace has some HTTP
|
||||
endpoints. Currently, two are implemented. The first, `/bus/env`, sends key/value pairs to
|
||||
update each node's Spring Environment. The second, `/bus/refresh`, reloads each
|
||||
application's configuration, as though they had all been pinged on their `/refresh`
|
||||
endpoint.
|
||||
|
||||
NOTE: The Spring Cloud Bus starters cover Rabbit and Kafka, because those are the two most
|
||||
common implementations. However, Spring Cloud Stream is quite flexible, and the binder

||||
works with `spring-cloud-bus`.

[[bus-endpoints]]
|
||||
== Bus Endpoints
|
||||
|
||||
Spring Cloud Bus provides two endpoints, `/actuator/busrefresh` and `/actuator/busenv`
|
||||
that correspond to individual actuator endpoints in Spring Cloud Commons,
|
||||
`/actuator/refresh` and `/actuator/env` respectively.
|
||||
|
||||
[[bus-refresh-endpoint]]
|
||||
=== Bus Refresh Endpoint
|
||||
The `/actuator/busrefresh` endpoint clears the `RefreshScope` cache and rebinds
|
||||
`@ConfigurationProperties`. See the <<refresh-scope,Refresh Scope>> documentation for
|
||||
more information.
|
||||
|
||||
To expose the `/actuator/busrefresh` endpoint, you need to add following configuration to your
|
||||
application:
|
||||
|
||||
[source,properties]
|
||||
----
|
||||
management.endpoints.web.exposure.include=busrefresh
|
||||
----
|
||||
|
||||
[[bus-env-endpoint]]
|
||||
=== Bus Env Endpoint
|
||||
The `/actuator/busenv` endpoint updates each instances environment with the specified
|
||||
key/value pair across multiple instances.
|
||||
|
||||
To expose the `/actuator/busenv` endpoint, you need to add following configuration to your
|
||||
application:
|
||||
|
||||
[source,properties]
|
||||
----
|
||||
management.endpoints.web.exposure.include=busenv
|
||||

|
||||
|
||||
The `/actuator/busenv` endpoint accepts `POST` requests with the following shape:
|
||||
|
||||
[source,json]
|
||||
----
|
||||
{
|

||||
|
||||
[[addressing-an-instance]]
|
||||
== Addressing an Instance
|
||||
|
||||
Each instance of the application has a service ID, whose value can be set with
|
||||
`spring.cloud.bus.id` and whose value is expected to be a colon-separated list of
|
||||
identifiers, in order from least specific to most specific. The default value is
|
||||
constructed from the environment as a combination of the `spring.application.name` and
|
||||
`server.port` (or `spring.application.index`, if set). The default value of the ID is
|
||||
constructed in the form of `app:index:id`, where:
|
||||
|
||||
* `app` is the `vcap.application.name`, if it exists, or `spring.application.name`
|
||||
* `index` is the `vcap.application.instance_index`, if it exists,
|
||||
`spring.application.index`, `local.server.port`, `server.port`, or `0` (in that order).
|
||||
* `id` is the `vcap.application.instance_id`, if it exists, or a random value.
|
||||
|
||||
The HTTP endpoints accept a "`destination`" path parameter, such as
|
||||
`/busrefresh/customers:9000`, where `destination` is a service ID. If the ID
|
||||
is owned by an instance on the bus, it processes the message, and all other instances
|
||||
ignore it.
|
||||
|
||||
[[addressing-all-instances-of-a-service]]
|
||||
== Addressing All Instances of a Service
|
||||
|
||||
The "`destination`" parameter is used in a Spring `PathMatcher` (with the path separator
|
||||
as a colon -- `:`) to determine if an instance processes the message. Using the example
|
||||
from earlier, `/busenv/customers:**` targets all instances of the
|
||||
"`customers`" service regardless of the rest of the service ID.
|
||||
|
||||
[[service-id-must-be-unique]]
|
||||
== Service ID Must Be Unique
|
||||
|
||||
The bus tries twice to eliminate processing an event -- once from the original
|
||||
`ApplicationEvent` and once from the queue. To do so, it checks the sending service ID
|
||||
against the current service ID. If multiple instances of a service have the same ID,
|
||||
events are not processed. When running on a local machine, each service is on a different
|
||||
port, and that port is part of the ID. Cloud Foundry supplies an index to differentiate.
|
||||
To ensure that the ID is unique outside Cloud Foundry, set `spring.application.index` to
|
||||
something unique for each instance of a service.
|
||||
|
||||
[[customizing-the-message-broker]]
|
||||
== Customizing the Message Broker
|
||||
|
||||
Spring Cloud Bus uses https://cloud.spring.io/spring-cloud-stream[Spring Cloud Stream] to
|
||||
broadcast the messages. So, to get messages to flow, you need only include the binder
|
||||
implementation of your choice in the classpath. There are convenient starters for the bus
|
||||
with AMQP (RabbitMQ) and Kafka (`spring-cloud-starter-bus-[amqp|kafka]`). Generally
|
||||
speaking, Spring Cloud Stream relies on Spring Boot autoconfiguration conventions for
|
||||
configuring middleware. For instance, the AMQP broker address can be changed with
|
||||
`spring.rabbitmq.{asterisk}` configuration properties. Spring Cloud Bus has a handful of
|
||||
native configuration properties in `spring.cloud.bus.{asterisk}` (for example,
|
||||
`spring.cloud.bus.destination` is the name of the topic to use as the external
|
||||
middleware). Normally, the defaults suffice.
|
||||
|
||||
To learn more about how to customize the message broker settings, consult the Spring Cloud
|
||||
Stream documentation.

== Tracing Bus Events
|
||||
|
||||
Bus events (subclasses of `RemoteApplicationEvent`) can be traced by setting
|
||||
`spring.cloud.bus.trace.enabled=true`. If you do so, the Spring Boot `TraceRepository`
|
||||
(if it is present) shows each event sent and all the acks from each service instance. The
|
||||
following example comes from the `/trace` endpoint:
|
||||
|
||||
[source,json]
|
||||
----
|
||||
{
|
||||
"timestamp": "2015-11-26T10:24:44.411+0000",
|
||||
"info": {
|
||||
"signal": "spring.cloud.bus.ack",
|
||||
"type": "RefreshRemoteApplicationEvent",
|
||||
"id": "c4d374b7-58ea-4928-a312-31984def293b",
|
||||
"origin": "stores:8081",
|
||||
"destination": "*:**"
|
||||
}
|
||||
},
|
||||
{
|
||||
"timestamp": "2015-11-26T10:24:41.864+0000",
|
||||
"info": {
|
||||
"signal": "spring.cloud.bus.sent",
|
||||
"type": "RefreshRemoteApplicationEvent",
|
||||
"id": "c4d374b7-58ea-4928-a312-31984def293b",
|
||||
"origin": "customers:9000",
|
||||
"destination": "*:**"
|
||||
}
|
||||
},
|
||||
{
|
||||
"timestamp": "2015-11-26T10:24:41.862+0000",
|
||||
"info": {
|
||||
"signal": "spring.cloud.bus.ack",
|
||||
"type": "RefreshRemoteApplicationEvent",
|
||||
"id": "c4d374b7-58ea-4928-a312-31984def293b",
|
||||
"origin": "customers:9000",
|
||||
"destination": "*:**"
|
||||
}
|
||||
}
|
||||
----
|
||||
|
||||
The preceding trace shows that a `RefreshRemoteApplicationEvent` was sent from
|
||||
`customers:9000`, broadcast to all services, and received (acked) by `customers:9000` and
|
||||
`stores:8081`.
|
||||
|
||||
To handle the ack signals yourself, you could add an `@EventListener` for the
|
||||
`AckRemoteApplicationEvent` and `SentApplicationEvent` types to your app (and enable
|
||||
tracing). Alternatively, you could tap into the `TraceRepository` and mine the data from
|
||||
there.
|
||||
|
||||
NOTE: Any Bus application can trace acks. However, sometimes, it is
|
||||
useful to do this in a central service that can do more complex
|
||||
queries on the data or forward it to a specialized tracing service.
|
||||
|
||||
[[broadcasting-your-own-events]]
|
||||
== Broadcasting Your Own Events
|
||||
|
||||
The Bus can carry any event of type `RemoteApplicationEvent`. The default transport is
|
||||
JSON, and the deserializer needs to know which types are going to be used ahead of time.
|
||||
To register a new type, you must put it in a subpackage of
|
||||
`org.springframework.cloud.bus.event`.
|
||||
|
||||
To customise the event name, you can use `@JsonTypeName` on your custom class or rely on
|
||||
the default strategy, which is to use the simple name of the class.
|
||||
|
||||
NOTE: Both the producer and the consumer need access to the class definition.
|
||||
|
||||
[[registering-events-in-custom-packages]]
|
||||
=== Registering events in custom packages
|
||||
|
||||
If you cannot or do not want to use a subpackage of `org.springframework.cloud.bus.event`
|
||||
for your custom events, you must specify which packages to scan for events of type
|
||||
`RemoteApplicationEvent` by using the `@RemoteApplicationEventScan` annotation. Packages
|
||||
specified with `@RemoteApplicationEventScan` include subpackages.
|
||||
|
||||
For example, consider the following custom event, called `MyEvent`:
|
||||
|
||||
[source,java]
|
||||
----
|
||||
package com.acme;
|
||||
|
||||
public class MyEvent extends RemoteApplicationEvent {
|
||||
...
|
||||
}
|
||||
----
|
||||
|
||||
You can register that event with the deserializer in the following way:
|
||||
|
||||
[source,java]
|
||||
----
|
||||
package com.acme;
|
||||
|
||||
@Configuration
|
||||
@RemoteApplicationEventScan
|
||||
public class BusConfiguration {
|
||||
...
|
||||
}
|
||||
----
|
||||
|
||||
Without specifying a value, the package of the class where `@RemoteApplicationEventScan`
|
||||
is used is registered. In this example, `com.acme` is registered by using the package of
|
||||
`BusConfiguration`.
|
||||
|
||||
You can also explicitly specify the packages to scan by using the `value`, `basePackages`
|
||||
or `basePackageClasses` properties on `@RemoteApplicationEventScan`, as shown in the
|
||||
following example:
|
||||
|
||||
[source,java]
|
||||
----
|
||||
package com.acme;
|
||||
|
||||
@Configuration
|
||||
//@RemoteApplicationEventScan({"com.acme", "foo.bar"})
|
||||
//@RemoteApplicationEventScan(basePackages = {"com.acme", "foo.bar", "fizz.buzz"})
|
||||
@RemoteApplicationEventScan(basePackageClasses = BusConfiguration.class)
|
||||
public class BusConfiguration {
|
||||
...
|
||||
}
|
||||
----
|
||||
|
||||
All of the preceding examples of `@RemoteApplicationEventScan` are equivalent, in that the
|
||||
`com.acme` package is registered by explicitly specifying the packages on
|
||||
`@RemoteApplicationEventScan`.
|
||||
|
||||
NOTE: You can specify multiple base packages to scan.
|
||||

||||

The idea of this script is to update gh-pages branch with the generated docs. Without any options
|
||||
the script will work in the following manner:
|
||||
|
||||
- if there's no gh-pages / target for docs module then the script ends
|
||||
- for master branch the generated docs are copied to the root of gh-pages branch
|
||||
- for any other branch (if that branch is allowed) a subfolder with branch name is created
|
||||
and docs are copied there
|
||||
- if the version switch is passed (-v) then a tag with (v) prefix will be retrieved and a folder
|
||||
with that version number will be created in the gh-pages branch. WARNING! No allow verification will take place
|
||||
- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
|
||||
switch to gh-pages of that repo and copy the generated docs to `docs/<project-name>/<version>`
|
||||
- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
|
||||
switch to gh-pages of that repo and copy the generated docs to `docs/<project-name>/<version>`
|
||||
|
||||
USAGE:
|
||||
|
||||
You can use the following options:
|
||||
|
||||
-v|--version - the script will apply the whole procedure for a particular library version
|
||||
-d|--destination - the root of destination folder where the docs should be copied. You have to use the full path.
|
||||
E.g. point to spring-cloud-static folder. Can't be used with (-c)
|
||||
-b|--build - will run the standard build process after checking out the branch
|
||||
-c|--clone - will automatically clone the spring-cloud-static repo instead of providing the destination.
|
||||
Obviously can't be used with (-d)
