Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram of an implementation principle of an information synchronization method in the prior art. As shown in fig. 1, in the prior art, a first service system produces a message, then pushes the message to a message queue, and then the message queue sends the message to a second service system subscribing to the message, and the second service system consumes the message. The first service system in the synchronization mode cannot acquire the consumption condition of the message receiver to the message, and data of the first service system and the second service system may be inconsistent.
For example, after the policy issuing system of the insurance system and the internet area successfully issues the policy, the policy data is sent to the message queue, but at this time, the policy data is not really taken away by the core service system due to various reasons such as the network, and the data of the policy issuing system and the core service system are inconsistent. If the settlement cannot be found in time, the settlement amount of the two systems is inconsistent during settlement, so that the settlement fails. The embodiment of the invention optimizes the scheme and ensures the consistency of data among systems.
Fig. 2 is a schematic diagram of the main steps of the information synchronization method at the message sender according to the embodiment of the present invention. As shown in fig. 2, the information synchronization method according to the embodiment of the present invention is executed by a message sender, and mainly includes the following steps:
step S201: and storing the produced service data into a first local file, initializing the synchronous state of the service data and recording the synchronous state of the service data into the first local file. The message sender produces the service data, stores the service data into a local file of the message sender, and records the synchronous state of the service data in the local file. The synchronous state comprises a storage state and a feedback state, and during initialization, the storage state of the service data is set to be stored, and the feedback state of the service data is set to be not fed back. In one embodiment, custom characters may be used to indicate various states, such as the letter Y indicating sent, fed back, and the letter N indicating not sent, not fed back.
Step S202: and sending the service data to a first message queue, so that the first message queue sends the service data to a message receiver subscribed with the service data. And a first message queue is established in advance, and a message receiving party subscribes service data from the first message queue. And the message sending party sends the service data to the first message queue. And then the first message queue sends the service data to a message receiver subscribing the service data. And after receiving the service data, the message receiver generates corresponding feedback information and sends the feedback information to the second message queue.
Step S203: and updating the synchronization state when the pre-subscribed feedback information from the second message queue is received. The feedback information is generated by the message receiving party when the service data exists in the second local file, and then is sent to the second message queue. And a second message queue is pre-established, and a message sender subscribes feedback information of the service data from the second message queue. The second message queue sends the feedback information to the message sender who subscribes to the feedback information. And then the message receiver can update the synchronization state of the service data in the local file, namely, the feedback state of the service data is updated to be fed back.
Step S204: and scanning the first local file to acquire the current synchronization state of the service data, and resending the service data to the first message queue according to the current synchronization state. The message sending party can scan the local file regularly or irregularly, obtain the current synchronization state of the service data produced by the message sending party from the local file, if the feedback state in the current synchronization state is not feedback and the synchronization time is greater than the set time threshold, the message receiving party can be considered to consume the service data abnormally, and the service data is pushed to the first message queue again to be sent to the message receiving party again.
Fig. 3 is a schematic diagram of the main steps of the information synchronization method at the message receiver according to the embodiment of the present invention. As shown in fig. 3, the information synchronization method according to the embodiment of the present invention is executed by a message receiver, and mainly includes the following steps:
step S301: and receiving pre-subscribed service data from the first message queue, and inquiring a second local file according to the set dimension field of the service data. And a first message queue is established in advance, and a message receiving party subscribes service data from the first message queue. And after the message sending party generates the service data, the service data is sent to the first message queue, and the first message queue is sent to the message receiving party. And the message receiver inquires the local file according to the set dimension field of the service data and judges whether the service data exists in the local file of the message receiver. For example, whether the service data exists in the local file of the user is queried through the service identification of the service data.
Step S302: and when the business data do not exist in the second local file, storing the business data into the second local file. If the message receiver does not inquire the service data in the local file, the message receiver stores the service data in the local file, that is, adds the data record of the service data in the local file, and then executes step S303. If the message receiver inquires the service data in its local file, step S303 is directly executed.
Step S303: and generating corresponding feedback information for the service data, and sending the feedback information to a message sender subscribing the feedback information in advance by using a second message queue so that the message sender updates the synchronization state of the service data stored in the first local file. And a second message queue is pre-established, and a message sender subscribes feedback information of the service data from the second message queue. And the message receiving party generates feedback information for the service data and sends the feedback information to the second message queue. And then the second message queue sends the feedback information to the message sender. And the message receiver can update the synchronization state of the service data in the local file after receiving the feedback information.
Fig. 4 is a timing diagram of an information synchronization method according to an embodiment of the present invention. As shown in fig. 4, the information synchronization method according to the embodiment of the present invention is executed by a first service system (i.e., a message sending side), a message queue, and a first service system (i.e., a message receiving side), so as to implement information synchronization between systems, and the systems are decoupled from each other, and the method mainly includes the following steps:
step S401: a first message queue and a second message queue are established. A first message queue Q1 and a second message queue Q2 are established. The first message queue Q1 is mainly used for receiving a subscription request of the second service system and forwarding service data; the second message queue Q2 is mainly used for receiving a subscription request of the first service system and forwarding feedback information. Taking the insurance system as an example, the first business system can be an order issuing system and is responsible for carrying traffic and completing the work of underwriting and issuing orders; the second service system may be a core service system, and is responsible for settlement of claims, supervision and delivery, channel settlement, and the like.
Step S402: the first service system stores the produced service data into a first local file, and records the synchronization state in the first local file. Taking the insurance system as an example, the service data is policy data, and the first local file may be a policy table stored in the first service system. In an embodiment, the policy data may include: policy number, order number, product number, time of application, time of endorsement, policy validation day, policy expiration day, payment method, information on the person to be insured, premium, payment information, etc.
In an embodiment, the policy table may include: all policy data, synchronization status, creation time, update time, version number. And storing the policy data into a policy table, namely adding a data record of the policy data in the policy table, wherein the data record contains the initial synchronization state of the policy data. The synchronous state comprises a storage state and a feedback state, and the storage state is Y at the beginning and represents that the service data is sent; the feedback state is N.
Step S403: the first business system sends the business data to the first message queue, and the first message queue sends the business data to a second business system which subscribes the business data. The first business system pushes the policy data to a first message queue Q1. The first message queue Q1 sends the service data to a second service system that subscribes to the service data.
Step S404: the second service system determines whether the second local file has service data, and if the second local file does not have service data, step S404 is executed; if the second local file has the service data, step S405 is performed. In an embodiment, the second local file may be a policy table stored in the second service system. The specific contents of the policy table may be the same as the policy table of the first service system. And the second service system judges whether policy data exist in the policy table of the second service system or not, and performs different processing according to the judgment result.
Step S405: and the second service system stores the service data into a second local file. When there is no policy data in the policy table of the second service system, the policy data needs to be stored in the policy table in the same transaction.
Step S406: and the second service system generates corresponding feedback information and sends the feedback information to the first service system subscribed with the feedback information from the second message queue. If the policy data exists in the policy table of the second service system or the policy data does not exist in the policy table of the second service system but is stored in the policy table, the second service system generates corresponding feedback information for the policy data and pushes the feedback information to the second message queue. In an embodiment, the feedback information may include: warranty number, processing result code, processing result text description and processing time. And the second message queue sends the feedback information to the first service system subscribed with the feedback information.
Step S407: and the first service system updates the synchronization state of the service data in the first local file. And after receiving the feedback information corresponding to the service data, the first service system updates the synchronization state of the service data in the policy table, namely, the feedback state is updated to be fed back. For example, the feedback status of the service data in the policy table is updated to Y. If the synchronization state and the feedback state are Y, the policy data is successfully stored in the policy table, and the feedback information is successfully sent, which indicates that the synchronization is successful. If any one of the two environments of storing the policy table and sending the feedback information fails, the synchronization fails, and the policy table rolls back.
Step S408: the first service system scans the first local file at regular time to acquire the current synchronization state of the service data, so as to automatically retransmit the service data or send alarm information according to the current synchronization state. In order to implement real-time processing on the service data which fails to be synchronized, the first service system may scan the first local file at regular time to obtain a current synchronization state of the service data, and if a feedback state in the current synchronization state is unrevealed and the synchronization time is greater than a set time threshold, the service data is re-sent to the first message queue. The synchronization time can be obtained by the difference between the current system time and the time for sending the service data. If the synchronization time is greater than the time threshold, the service data can be automatically retransmitted. It should be noted that the present embodiment does not limit the execution sequence of the steps, and as long as the timing time is reached, the steps may be executed in any one of the above-mentioned flows.
In another preferred embodiment, in the case of no feedback after timeout, in order to determine whether synchronization fails due to a failure of the second service system, the first service system may scan the first local file to obtain current synchronization states of the plurality of service data; then counting the number of data records of which the feedback state in the current synchronization state is unrevealed and the synchronization time is greater than a time threshold; comparing the number of the data records with the set alarm threshold value, and if the number of the data records is greater than or equal to the alarm threshold value, sending alarm information; and if the number of the data records is less than the alarm threshold value, retransmitting the plurality of service data to the first message queue.
The alarm threshold value can be set by self-definition. For example, the alarm threshold is 100. And if the number of the data records is less than 100, the business data with the synchronization failure is pushed to the first message queue again. And if the number of the data records is more than or equal to 100, sending alarm information to inform system operation and maintenance personnel to check whether the second service system has a fault, receiving a manual instruction after the fault is eliminated, and pushing the service data which fails in synchronization to the first message queue again.
It should be noted that the embodiment of the present invention does not limit the number of the first message queue Q1 and the second message queue Q2, that is, the first message queue Q1 and the second message queue Q2 may include a plurality of sub message queues, and the sub message queues implement the synchronization function.
According to the information synchronization method, the message sending party subscribes the feedback information of the produced service data to the second message queue, the message receiving party generates feedback information after receiving the service data and sends the feedback information to the message sending party through the second message queue, so that the message sending party can acquire the synchronization result in time and the subsequent processing is convenient; the synchronization state comprises a storage state and a feedback state of the service data, and whether the synchronization is successful can be determined according to the values of the two states, so that the method is simple to implement; the local file is scanned at regular time, and whether the service data is not synchronized to a message receiver after timeout is determined, so that the subsequent automatic resending is facilitated, and the data consistency is ensured; and counting the number of the data records which are not synchronized overtime, and carrying out alarm processing or automatic retry according to the number of the data records and the size of a set alarm threshold value to ensure the data consistency.
