Active MQ+Redis-based synchronous message queue

Abstract

The invention discloses an Active MQ+Redis-based synchronous message queue. The Active MQ+Redis-based synchronous message queue comprises the following steps of: creating a connection and a dialogue of an Active MQ message queue; inserting messages to the Active MQ message queue; receiving the messages by consumers, and recording the sequence of the messages by a list data structure of a Redis; sending a distributed lock to the consumers by the Redis according to the sequence of the messages; enabling the consumer that obtains the distributed lock as a leader, consuming the messages, releasing the distributed lock after the consumption is finished, and continuing to monitoring the messages; and continuing to waiting for obtaining the distributed lock by the consumers that do not obtain the distributed lock. The Active MQ+Redis-based synchronous message queue has the beneficial effects of solving the problem that program faults are easy to occur when a plurality of consumers consume messages in distributed message queues in parallel, realizing the sequential consumption among the plurality of consumers, and filling the technical gap of the Active MQ+Redis-based synchronous message queue.

Description

technical field [0001] The invention belongs to the technical field of synchronous message queue execution, and in particular relates to a synchronous message queue based on ActiveMQ+Redis. Background technique [0002] In the case of a message queue with only one consumer, if the consumer's machine fails, it cannot complete the full consumption of messages. At this time, if you want to continue to consume messages, you need to switch to other machines for operation, that is, in the system Set up multiple consumer terminals; and the consumption of messages by multiple consumers requires sequential execution. In the scenario where multiple consumers consume messages from a distributed message queue in parallel, how to maintain the sequential consumption among multiple consumers? It is an important problem that needs to be solved urgently. [0003] In actual business scenarios, for example: multiple teachers import student information at the same time, and in the scenario whe...
