Embodiment Construction

[0091] The present invention will be further described below in conjunction with specific examples.

[0092] An efficient cache management method based on data version, which makes up for the lack of MyBatis secondary cache control, improves the synchronization and consistency of secondary cache Cache and database data, and handles the relationship between each cache; accurately manages MyBatis Second-level cache, to achieve fine-grained control of MyBatis second-level cache; when the update operation on the database table is performed, you can specify to clear the cache generated by the query statement represented by a specific StatementId; the maintenance of the cache is independent , the caches will not affect each other. The statements in the specified Mapper will only affect the Cache corresponding to the Mapper. When some update operations are performed, the cache generated by a specific query statement can be refreshed or cleared to avoid data inconsistency .

Abstract

The invention discloses a method for efficiently managing caches based on data versions, and belongs to the technical field of software development. The method for efficiently managing the caches based on the data versions makes up insufficiency of MyBatis second-level cache control, synchronization and consistency of second-level caches and database data are improved, and correlations between each cache are processed; the second-level cashes of MyBatis are accurately managed, and fine granularity of the MyBatis second-level caches is controlled; when updating operation is executed on a database table, caches generated by a query statement which is represented by a specific StatementId can be specifically cleared. According to the method for efficiently managing the caches based on the data versions, the problem is solved that database pressure is caused by a large amount of interaction between a system and a database in an existing software development process, the requirement of consistency of business data is met, at the same time, the difficulty of code development is reduced, and the performance and concurrent capability of existing or newly-established systems are improved.

Description

technical field [0001] The invention relates to the technical field of software development, in particular to a method for efficiently managing caches based on data versions. Background technique [0002] In software development, quite a lot of content needs to interact with the database. The general processing is to exchange data directly with the database. However, the processing tasks of the database are quite heavy, and often become the key link of slow system operation or downtime. Even if caching technology is used, the cache will be directly operated by the developer, which requires high development ability and code quality of the developer. [0003] MyBatis is a technical framework for data persistence, which mainly supports the interaction between business applications and databases. It has been widely used in J2EE-based development technology platforms. MyBatis provides a second-level cache mechanism that can simply cache corresponding data, but the synchronizatio...
