To run the example, simply type mvn verify from this directory, or mvn -PnoServer verify if you want to start and create the broker manually.
This example shows you how to configure a ActiveMQ Artemis queue with static message selectors (filters).
Static message selectors are ActiveMQ‘s extension to message selectors as defined in JMS spec 1.1. Rather than specifying the selector in the application code, static message selectors are defined in one of ActiveMQ’s configuration files, broker.xml, as an element called filter inside each queue definition, like
Once configured the queue selectorQueue only delivers messages that are selected against the filter, i.e., only the messages whose color properties are of red values can be received by its consumers. Those that don't match the filter will be dropped by the queue and therefore will never be delivered to any of its consumers.
In the example code, five messages with different color property values are sent to queue selectorQueue. One consumer is created to receive messages from the queue. Of the five sent messages, two are of red color properties, one is blue, one is green and one has not the color property at all. The result is that the consumer only gets the two red messages.
