Problems solved by technology

[0009] Thread copy: The reason why multi-thread concurrency is unsafe is because threads do not own resources, they share and compete for resources of the process, so threads are not safe to start concurrently, and the general solution is to use locks to ensure that one resource at a time Can only be owned by at most one thread

Embodiment Construction

[0036] Such as figure 1 As shown, the present invention relies on the annotation mechanism of SpringBoot to design a set of annotations, complete the dynamic database connection pool structure, and inject it into the Spring context. The dynamic data source determines which data source to use by obtaining the data source name of the local thread copy. At the same time, through the principle of aspect programming, the business layer uses annotations to parse out the name of the data source configured on the calling method and store it in the local thread copy.

[0037] Data source configuration: application.yml is the default configuration file of SpringBoot. We use the style of SpringBoot to configure the database architecture of Master-Slaves and support multiple Slave nodes;

[0038] Initialize the data source: According to the data source configuration items and different database addresses, different database connection pools are formed and called when needed;

[0039] Def...

Abstract

The invention provides a method for realizing database dynamic switching, which comprises the following steps of analyzing a data source configuration file to form a corresponding database connectionpool; defining a set of annotations of data source switching; analyzing the annotation, and placing the database name in a local thread copy; returning the database object corresponding to the database name in the thread copy to the Spring framework to realize dynamic switching of the database. The invention further provides a computer readable storage medium, high cohesion and low coupling can beachieved without other service control codes, and the performance is not affected. On the basis, database read-write separation can be realized through configuration.

Description

technical field [0001] The invention relates to a method for realizing dynamic database switching and a computer-readable storage medium. Background technique [0002] For large-scale Internet applications, the number of records in a single table of the database may reach tens of millions, and the database is faced with extremely high concurrent access. In order to meet high concurrent access and ensure high availability of the database, an effective way is to adopt a read-write separation architecture to ease the read-write pressure of a single data database; the read-write separation architecture refers to: a main database is used to write data , multiple slave databases complete the operation of reading data, and the master-slave database synchronizes data through a certain mechanism; to achieve read-write separation in a project, the database connection pool must be distinguished, which ones are read connection pools, and which ones are written Connection pool; the trad...
