Data access method and device

Abstract

The invention provides a data access method and device. A data access class, a cache configuration parameter and a corresponding relationship of a corresponding cache strategy class is stored in a preset cache configuration parameter area, wherein the cache configuration parameter comprises a cache table identifier configuration item, a cache type configuration item, an application service initialization loading configuration item, a query option configuration item and a cache data initialization configuration item; in this way, when a data access request sent by a user is received, the data access request is attached with the data access class of the cache annotation, a cache table identifier to which a data access class belongs can be obtained; a cache configuration parameter corresponding to the cache table identifier is searched from a preset cache configuration parameter area, and the cache strategy class corresponding to the cache type configuration item in the cache configuration parameter is calle to execute the data query operation, and the data query result is fed back to the user. Through the method and the device, the development process can be simplified, the normal access of the data can be ensured when the cache is abnormal, and the release of a shutdown announcement is avoided.

Description

technical field [0001] The present application relates to the technical field of data caching, and in particular, to a data access method and device. Background technique [0002] Bank of China's overseas core system provides services for all overseas peripheral systems in the form of distributed services, including: loan, deposit, payment, batch, debit card, teller and other application modules. The transactions are complex and the data is huge, and the access to the database is very frequent. This affects the transaction processing performance of overseas core systems. [0003] At present, the problem of transaction processing performance caused by frequent database access is mainly solved by caching technology. For complex systems, due to the large number of data access scenarios involved, different data access scenarios may require different caching methods. For example, for system parameters with a small amount of data and infrequent changes, use fast and efficient mem...

AI Technical Summary

Problems solved by technology

[0005] This application provides a data access method and device, the purpose of which is to solve the problem that in the prior art, when it is necessary to increase or modify the cache mode or the cache is abnormal, the system developer needs to re-develop the code due to the need to issue a business closure notice. After the code development is completed, the application service needs to be restarted to realize the normal access to the data, and thus cannot guarantee the normal access to the data
