Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the defect that the Mybatis system in the prior art is not suitable for the multi-database system of the sharding framework, provide a method for accessing the fragmented database and its database system, and utilize the existing Mybatis and Spring framework , realize the operation of the sharding database through the routing strategy

Embodiment Construction

[0056] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0057] The database system of this embodiment adopts Mybatis and Spring framework to realize the operation on the sharding database, that is, to realize the configurability of database access. It is convenient to configure the database access routing strategy through the configuration file. And it makes the development of database applications transparent. In addition, the problem that the efficiency of data access is likely to decrease with the increase of the database is suppressed. And ensure the correctness of data access. That is, multi-database commit or multi-database rollback is implemented in multi-database transaction operations to ensure data consistency and correctness. SQL operations such as summation, counting, query maximum value, query minimum value, sorting, paging, etc. of the multi-database can be used no...

Abstract

The invention discloses a fragmentation database access method and a database system. The fragmentation database access method is used for frameworks of Mybatis and Spring and includes the following steps that 1 databases to be accessed are located through a Spring configuration file based on a database affair; 2 an access thread is built for each database to be accessed; 3 a database operation interface of the Mybatis operates the databases to be accessed and correlated to the access threads through the access threads, collects fed back data of the access threads and generates an execution result; 4 an affair management interface of the Spring detects whether the database affair is executed successfully based on the execution result of the database operation interface and executes corresponding submitting and rolling back. A database system using the fragmentation database access method is further provided. By means of the method and the system, the existing frameworks are utilized to achieve paging database operation through a routing strategy.

Description

technical field [0001] The invention relates to a sliced ​​database access method and a database system, in particular to a sliced ​​database access method and a database system suitable for Mybatis and Spring frameworks. Background technique [0002] Database expansion is an eternal topic. For traditional relational databases, the method of vertical expansion (ScaleUp) is adopted, that is, to buy better machines and add more resources to achieve better performance (such as hardware upgrades, faster and more CPUs (central processing units) , more memory, more and larger disks, etc.). Relational databases have dominated the traditional enterprise application environment for nearly thirty years through the ScaleUp approach. However, with the surge in data volume in recent years, especially the emergence of the cloud computing model, this expansion mode is not suitable for some applications. At this time, a horizontal expansion (ScaleOut) mode appears, and sharding is one of ...
