public interface MatsTestBrokerInterface
RuntimeException
, or the special MatsRefuseMessageException
due to some
internal validation performed.
Usage: If employing the Mats test tools, one of these should have been created for you. For the JUnit
Rule_Mats
, and JUnit Jupiter Extension_Mats
, there's a getter directly on the
rule/extension instance. For Spring, employing the @MatsTestContext
or corresponding
MatsTestInfrastructureConfiguration
, an instance is put into the Spring context for you. If you do not
use those tools, you will have to create a instance of this class as a Spring bean yourself - either directly by
using the create(..)
methods taking parameters, or indirectly by
using the createForLaterPopulation()
variant, and rely on the SpringJmsMatsFactoryWrapper
finding it from the Spring context and populating it for you.Modifier and Type | Interface and Description |

_latePopulate(javax.jms.ConnectionFactory connectionFactory,

This method is most probably not for you!.
|
static MatsTestBrokerInterface |
create(javax.jms.ConnectionFactory connectionFactory,
MatsFactory matsFactory)
If you have both the JMS ConnectionFactory and a JmsMatsFactory available from start, then you can create a
working instance right away.

createForLaterPopulation()
Special factory variant, where the needed parameters must be supplied by
_latePopulate(ConnectionFactory, MatsFactory) , which typically will be handled by the
SpringJmsMatsFactoryWrapper . |

getDlqMessage(java.lang.String endpointOrStageId)
Waits a couple of seconds for a message to appear on the Dead Letter Queue for the provided endpoint- or stageId
(Queue name "DLQ."+matsendpointPrefix+endpointOrStageId) - and also checks the standard common ActiveMQ DLQ
(Queue name "ActiveMQ.DLQ") in case the broker is not configured with specific DLQs per Queue, which is relevant
if you fire up an unmodified ActiveMQ distribution on the command line, check the
MatsTestBroker class
JavaDoc for how to use an external MQ instead of the in-VM which otherwise is fired up. |

class
JavaDoc for how to use an external MQ instead of the in-VM which otherwise is fired up. (NOTE: It is HIGHLY
suggested to use the "specific DLQ" pattern in any production setting, as this is much easier to reason about
when ugly things starts hitting fans).endpointOrStageId

SpringJmsMatsFactoryWrapper
, by
reflection invocation when it is both on classpath and as an instance in the Spring context, to perform "late
setting" of the properties which the tool needs to perform its job. (Reason for reflection: This class resides in
the 'mats-test' project - which is for testing, while the SpringJmsMatsFactoryWrapper
is in the
'mats-spring-jms' project - which is for "production").
The matsFactory parameter currently needs to be a JmsMatsFactory. We need all of the following from it
matsFactory.getFactoryConfig().getMatsDestinationPrefix()
(standard MatsFactory)matsFactory.getFactoryConfig().getMatsTraceKey()
(standard MatsFactory)MatsInterceptable
, which JmsMatsFactory is)MatsSerializer
to provide access to contents from messages (from JmsMatsFactory)MatsFactory.MatsFactoryWrapper
, but it must resolve to a
JmsMatsFactory
via the MatsFactory.unwrapFully()
! Otherwise, it'll throw an
IllegalArgumentException
