Description
Technical Field
The invention relates to the technical field of data communication, can be used in the financial field, and particularly relates to a message processing method and device based on a message queue.
Background
Due to the fact that different systems are involved, message transmission between banks is achieved through Message Queue (MQ) middleware, and messages are stored and transmitted between every two systems through the MQ queues. When the message sent by the sending end is not taken away by the receiving end, the message stays in the queue all the time, which is itself worthy of celebration because the message is not lost as long as it is not taken away.
However, sometimes, the number of messages in the MQ queue is accumulated due to the problems of the network or the system itself, and if the network or the system cannot recover in a short time, when the maximum number of messages that can be stored in the queue is reached, the subsequent messages cannot be received, and the messages are lost. If the existing messages in the MQ queue are important at this point, then neither the messages already stored in the queue can be deleted, nor subsequent messages can continue to be received.
In addition, the messages accumulated in the MQ queue sometimes cause the queue manager to crash, and at this time, the messages in the MQ queue cannot be read even if the network or the system recovers, and the queue manager can only be restarted by deleting the messages in the MQ queue, so that unexpected serious results can be caused.

Detailed Description
The embodiment of the invention provides a message processing method and a message processing device based on a message queue, which can be used in the financial field and other fields.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
As shown in fig. 1, which is a schematic flow chart of a message processing method based on a message queue provided in an embodiment of the present application, a message sending party sends a message to a message queue in a gateway or a front-end system in detail, and then a message receiving party extracts a message from the message queue, where this embodiment is a description of the present application from a gateway or a front-end system side, and the method includes the following steps:
step S101: a message depth in a message queue from a sender message is detected.
The MQ queue has the maximum depth, namely the maximum upper limit of the number of messages that the queue can store, and the receiver in the prior art has the message interception function, namely the MQ queue is intercepted in real time, and when the messages exist in the MQ queue, the messages are automatically taken away, so that the message accumulation condition generally does not exist in the message queue. But when a network or system anomaly occurs and the data in the MQ queue is not taken by the receiver, a message pile-up condition occurs. The step is to embed a detection unit in the gateway or the front-end processor system for detecting the message depth of the MQ queue, namely the number of messages in the MQ queue in real time.
Step S102: and judging whether the message depth in the message queue reaches a preset value.
Step S103: and when the depth of the message in the message queue reaches a preset value, taking out the message from the message queue and storing the message in the local storage equipment.
In this embodiment, when an abnormality occurs in the network or system and the recovery does not occur in a short time, the messages in the MQ queue start to be accumulated, and when it is detected that the message depth reaches a preset value, that is, the number of messages reaches a preset value, the messages are taken away by using a message collecting unit arranged in the gateway or the front-end system and stored in a local storage device arranged in the gateway or the front-end system. The preset value in this step may be, for example, 50% of the maximum depth of the MQ queue, or 30%, and may be set according to practical situations and requirements, which is not limited in this embodiment of the application.
According to the technical scheme, when network or system faults occur and messages in the message queue are accumulated, all messages are taken out of the message queue and stored in the local storage device, so that the messages cannot be lost, the queue is smooth, and subsequent messages can be normally received by the message queue.
Fig. 2 is a schematic flow chart of a message processing method based on a message queue according to another embodiment of the present application, and this embodiment also describes the present application from a gateway or a front-end processor system side, where the method includes the following steps:
step S201: a message depth in a message queue from a sender message is detected.
Step S202: and judging whether the message depth in the message queue reaches a preset value, if so, entering the step S203, and if not, returning to the step S201.
Step S203: and taking out the message from the message queue.
Step S204: and judging whether a message storage file with the current date as the name exists in the local storage equipment, if so, entering the step S205, and if not, entering the step S206.
Step S205: and writing the extracted message into the message storage file.
Step S206: and creating a message storage file with the current date as the name and writing the taken message into the message storage file.
In this embodiment, when a message queue has message accumulation, only the message is taken out and stored, and when the message queue is recovered, the taken-out message is not operated, but it can be ensured that the message queue remains unblocked and the message is not lost when the network or system is abnormal.

step S301: a message depth in a message queue from a sender message is detected.
Step S302: and judging whether the message depth in the message queue reaches a preset value, if so, entering the step S303, and if not, returning to the step S301.
Step S303: and taking out the message from the message queue.
Step S304: and creating a message storage file for each message, and writing all the messages into the corresponding message storage file.
In this embodiment, in order to retransmit the taken messages after the network or system is recovered from an abnormal condition, a corresponding storage file is created for each message, so that the messages can be conveniently retransmitted to the message queue in the following process, and the message receivers can listen to and take away the messages.
Step S305: and continuously detecting the message depth of the messages in the message queue, judging whether the message depth meets the preset condition, and if so, taking out the messages from the local storage equipment and sending the messages to the message queue one by one.
