README
Integration of the CommandBus library into Symfony2.
Installation
Require rezzza/command-bus-bundle
to your composer.json
file:
{ "require": { "rezzza/command-bus-bundle": "~2.0" } }
Register the bundle in app/AppKernel.php
:
// app/AppKernel.php public function registerBundles() { return array( // ... new Rezzza\CommandBusBundle\RezzzaCommandBusBundle() ); }
Update your config.yml
:
framework: serializer: enabled: true
Usage
$bus = $container->get('rezzza_command_bus.command_bus.synchronous'); // synchronous is the name you given to your bus in configuration. $bus->handle(new FooCommand());
Bus
Direct, SncRedis & OldSoundRabbit are currently supported.
Commands
Commands must inherit from Rezzza\CommandBus\Domain\CommandInterface
.
Register a command handler:
<service id="...." class="...."> <tag name="rezzza_command_bus.command_handler" command="FQCN\MyFirstActionCommand" /> <!-- when handle this command, method `myFirstAction` will be handled. --> <tag name="rezzza_command_bus.command_handler" command="FQCN\MySecondActionCommand" method="myMethod" /> </service>
Events
Events:
- on_consumer_response
- pre_handle_command
Register a listener:
<service id="service_id" class="Foo"> <tag name="rezzza_command_bus.event_listener" event="pre_handle_command" method="onPreHandleCommand" /> <tag name="rezzza_command_bus.event_listener" event="on_consumer_response" method="onConsumerResponse" /> </service>
Fail Strategy
See command-bus documentation.
Console Command
A Symfony console command is provided in this bundle
$ app/console rezzza:command_bus:consume "CommandToConsume"
Options available:
--consumer Which consumer should we use ? (default: "default")
--iteration-limit (-i) Limit of iterations, -1 for infinite.. (default: -1)
--time-limit During how many time this command will listen to the queue. (default: 60)
--usleep Micro seconds (default: 100000)
--lock Only one command processing ?
To watch activity of your consumer, you should register a console handler for monolog
monolog: handlers: console: type: console verbosity_levels: VERBOSITY_NORMAL: NOTICE
Configuration
rezzza_command_bus: buses: synchronous: direct asynchronous: rabbitmq: #define producer_guesser which allow to determine rigth producer for each command #producer name and command class name must be indentical #example: #producer name : source_entry_update #command class name : SourceEntryUpdateCommand producer_guesser: rezzza_command_bus.old_sound_rabbit.producer_guesser consumer_bus: synchronous #consumer handle command with synchronous bus snc_redis: client: default # snc redis client. read_block_timeout: 1 # see blpop documentation consumers: default: bus: synchronous fail_strategy: retry_then_fail: # When the command fail, it uses this strategy. # you could use too requeue, none, service. attempts: 10 requeue_on_fail: true handlers: # Do you want to use handlers provided in this bundle ? retry: synchronous # If you used retry_then_fail strategy, this handler is linked to Retry commands. failed: synchronous # If you used retry_then_fail strategy, this handler is linked to Failed commands.
