java - Can JMS guarantee that a message in the queue can received by only one instance of receiver at a time? -

let's if there 1 sender sending 100 messages 1 1 queue , 3 receivers receiving messages queue, jms default define receivers not pick same message each receiver assigned different messages? or configurable perform so?

yes, consumers on queues compete messages.

topics on other hand publish/subscribe (all consumers them).

if consumer blows , message redelivered; there no guarantee message go same consumer.

java jms activemq spring-jms
