Example 1
Next, an embodiment of the system reconstruction method of the present invention will be described with reference to fig. 1 to 3.
Fig. 1 is a flow chart of an example of a system reconstruction method of the present invention.
As shown in fig. 1, the system reconstruction method of the present invention mainly includes the following steps.
In step S101, the old financial service system is connected with a message proxy server and a wind control approval system, and provides a data query service for a business end, where the message proxy server is used for proxy of business data related to financial products, and the wind control approval system is used for receiving message consumption related information data from the old financial service system.
Step S102, a new financial service system parallel to the old financial service system is constructed, all codes of the old financial service system are transplanted to the new financial service system, and the consumption mode of the old financial service system is changed into message idempotent.
Step S103, establishing a distributed database connected with the old financial service system and the new financial service system; the distributed database is used for receiving business data received by the old financial service system and the new financial service system from the message proxy server side respectively.
Step S104, comparing the business data of the old financial service system and the new financial service system, and verifying the query interface of the new financial service system.
Step S105, after verifying that each function index is normal, closing the old financial service system and switching the query interface to the new financial service system to complete the reconstruction system.
Fig. 2 is a schematic diagram of an example of an application scenario of the system reconstruction method of the present invention.
As shown in fig. 2, in the application scenario where the new and old systems coexist, multiple systems are connected and cooperate with each other, and there is an interdependence relationship, where the multiple systems include an old financial service system, a new financial service system, a financial product system, a wind control approval system, a universal gateway system, and the like, which are connected with each other to perform data interaction, so as to realize stable switching of minimum risk of the new and old systems.
It should be noted that, in this example, the financial service system (including the old financial service system and the new financial service system) is a real-time computing system for computing the user index, where the system is mainly used for performing real-time computation on multiple dimension indexes of the user, and provides data query service for the service end through the universal gateway system; the financial product system is a system for serving user resource applications and approvals; the wind control approval system is a system for service user trust and resource approval; the universal gateway system is connected with the service end and is used for serving the inquiry of external resources of the user; a distributed database for storing relevant business data is also included. The reconfiguration process of the new financial service system will be described in more detail below.
First, in step S101, an old financial service system is connected to a message proxy server for proxy of service data related to a financial product and a wind-control approval system for receiving message consumption related information data from the old financial service system, and provides a data query service to a service end.
In particular, the financial product system (LoanPlatform System, abbreviated as LPS) includes one or more financial services products or funds management products. The financial product System sends message data related to each financial product to an old financial service System, for example, a live System, which calculates user indexes such as user behavior data in real time, provides data query service for a service end through a general gateway System, and sends a message consumption completion notification to an Approval System (APV for short).
Further, the old financial service system is connected with the universal gateway system through the Http rest interface, in other words, the Http rest interface is a query interface for calling the old financial service system.
Next, in step S102, a new financial service system is constructed in parallel with the old financial service system, all codes of the old financial service system are transplanted to the new financial service system, and the consumption mode of the old financial service system is changed to message idempotent.
As shown in fig. 3, the method further includes a step S301 of listening to business data received by the new financial service system.
In step S301, service data received by a new financial service system is monitored, specifically, service data related to the financial product sent by a monitoring message proxy server to the new financial service system, and after consumption is delayed and shielded, a consumption completion notification is sent to the wind control approval system.
Specifically, the new financial service system further comprises switches corresponding to the interception and shielding data, and the corresponding operation codes are updated according to the interception and shielding data.
More specifically, the switches include a first switch for controlling and a second switch, wherein the first switch is used for saving data to the distributed database, and the second switch is used for sending message consumption related data to the wind control approval system.
Preferably, the first switch and/or the second switch is an interface-level hot-cut switch.
Further, the wind control approval system connected with the new financial service system directly establishes connection with a business end for a user to inquire related business data.
In this example, the query interface of the service end is switched to a dubbo interface, that is, the dubbo interface is a query interface for calling a new financial service system, and further, the wind control approval system is connected with the service end through the dubbo interface.
It should be noted that the new financial service system is a msf frame-based system, unlike the basic frame of the old financial service system, which is a springboot-based system. In addition, the new financial services system includes a number of other functions such as current limiting, monitoring, log collection, etc.
Next, in step S103, a distributed database connected to the old financial service system and the new financial service system is established, the distributed database being used for receiving service data received by the old financial service system and the new financial service system from the message broker server side, respectively.
Preferably, the distributed database is an Hbase database.
In this example, the message broker server receives business data from the financial product systems and transmits the corresponding business data to the old financial service system and the new financial service system during simultaneous consumption by the old and new systems.
Further, the old financial service system and the new financial service system both calculate the received business data in real time, provide data query service for the business end, and send a message consumption completion notification to a wind control approval system, wherein the wind control approval system can ensure that the message returned by the old financial service system is idempotent.
Next, in step S104, the business data of the old financial service system and the new financial service system are compared, and the query interface of the new financial service system is verified.
Specifically, in the test environment, the message consumption result of the new financial service system is compared with the message consumption result of the old financial service system by inquiring the latest data of the Hbase database, for example, the log is printed for comparison, so as to judge whether the message consumption transmission is normal or not.
Further, as the query interface of the new financial service system is changed to the dubbo interface, the dubbo interface is compared with the Http rest interface of the old financial service system.
In this example, the message consumption calculation logic received by the new and old financial service systems is also validated for consistency.
Further, each function index of the financial service system is verified.
Step S105, after verifying that each function index is normal, closing the old financial service system and switching the query interface to the new financial service system to complete the reconstruction system.
In this example, the function metrics include a message consumption sending metric, a business data falling-down metric, and a business data query metric.
Specifically, the new and old financial service systems are verified and compared in the test environment, and the double-writing database is synchronously consumed in the production environment.
In this example, after switching to the dubbo interface of the new financial service system, the first switch and the second switch are turned on, and a predetermined period of time is consumed in parallel with the old financial service system to verify whether the dubbo interface is consistent with the query interface of the old financial service system.
Further, after verifying that the function indexes are normal, the old financial service system is closed, and the old query interface is switched to the dubbo interface of the new financial service system, so that the reconstruction of the new financial service system is completed.
Therefore, by the system reconstruction method, the minimum risk stable switching of the new system and the old system is realized, the smooth upgrading of the system is ensured, and the safety and service availability of the mutual cooperation between the whole system and other systems are improved.
The above description is given by way of example only, and the present invention is not to be construed as being limited thereto.
