Description

Data storage method and device

Technical Field

The invention relates to a data storage method and a data storage device, and belongs to the field of computers.

Background

Currently, it is a common trade channel for buyers and suppliers to trade on-line. During the course of a transaction, the server may generate a large amount of data. In the prior art, a bottom-layer cache framework of a server generally uses a Redis, which is an open-source, network-supporting, memory-based, optional-persistence key-value pair storage database written by using an ANSIC.

Currently, in the caching process of the Redis, the sequence of reading data is to read the cache database first and then read the database, and the sequence of writing data is to write the database first and then write the cache database. After the relevant data is updated every time, the cache data in the cache database is cleaned, the problem that the data is inconsistent with the cache data is avoided, or failure time is set for the cache database, and the cache data is automatically cleaned after the failure time is reached, so that the consistency of the data and the cache data is ensured.

However, when the number of times of updating the cache is large, the operation is not only cumbersome and long in time delay, but also may cause a sequence error due to carelessness or capacity problems of a developer, which may cause a problem of data inconsistency.

Disclosure of Invention

The invention provides a data storage method, which can reduce a large amount of redundant codes and development cost, is convenient and quick to store and reduces codes interacting with a database.

The application provides a data storage method, which comprises the following steps:

adding annotations for automatically storing the data in the database into a redis cache on a redis API; and adding annotations for synchronously updating the data in the database into a redis cache on the redis API.

The annotation for automatically storing the data in the database into the redis cache is an @ Myredis annotation, and the @ Myredis annotation comprises cache expiration time.

The annotation for synchronously updating the data in the database into the redis cache is an @ Update annotation, and the @ Update annotation comprises a scope parameter.

Wherein the scope parameter is an enumerated value UpdateType.

Wherein the enumeration value is updatetype.

Wherein, the enumeration value is updatetype.class, which indicates that all caches under the current class are updated.

Wherein, if the enumerated value is updatetype.

The present application further provides a data caching apparatus, including:

the first adding module is used for adding annotations for automatically storing the data in the database into the redis cache on the redis API;

and the second adding module is used for adding annotations for synchronously updating the data in the database to the redis cache on the redis API.

The annotation added by the first adding module is an @ Myredis annotation, and the @ Myredis annotation comprises cache invalidation time.

The annotation added by the second adding module is an @ Update annotation, and the @ Update annotation comprises scope parameters.

According to the method, the @ Myredis annotation and the @ Update annotation are added to the redisAPI, data in the database with the @ Myredis annotation can be automatically stored in a redis cache only by one line of codes, and the data in the database with the @ Update annotation is synchronously updated in the redis cache, so that a large amount of redundant codes and development cost are reduced, the storage is convenient and fast, codes interacted with the database are reduced, and the data in the database and the cache are consistent;

furthermore, the invalidation time of the object in the redis cache can be automatically set, so that the consistency of the data and the cache data is further ensured;

furthermore, the range of the updated data is determined according to the enumeration value in the parameter of the @ Update annotation, so that the range of the data Update is defined, the data Update time is saved, and the efficiency of the data Update is improved.

Detailed Description

In order to make the objects, technical solutions, advantages, and the like of the present invention clearer, practical examples are given and further description is given with reference to the drawings.

As shown in fig. 1, the present application provides a data storage method, including:

101. adding an annotation for automatically storing data in a database into a redis cache on a redis API (application programming interface, hereinafter referred to as API);

specifically, adding an @ Myredis annotation on a redisAPI, wherein the @ Myredis annotation is used for automatically storing data in a database into a redis cache;

the @ Myredis annotation includes cache expiration time in seconds, and if default parameters are not set, the default expiration time is 720 seconds.

102. And adding annotations for synchronously updating the data in the database into a redis cache on the redis API.

Specifically, adding an @ Update annotation on the redisAPI, wherein the @ Update annotation is used for synchronously updating data in the database into the redis cache.

The @ Update annotation includes a scope parameter, and in practical application, the scope parameter is represented by an enumerated value UpdateType, and the UpdateType is used for describing the scope of the @ Update annotation, namely, the refresh range of the cache. When the enumeration value is UpdateType.ALL, all redis caches are updated; when the enumeration value is UpdateType.CLASS, updating all redis caches under the current class; NOW, indicating that all redis caches under the execution method are updated.

It should be noted that, the step 101 and step 102 do not have a determined execution order relationship, and the @ Myredis annotation may be added first and then the @ Update annotation is added on the basis of the redisa api, or the @ Update annotation may be added first and then the @ Myredis annotation is added, which is not limited in this embodiment of the present invention.

According to the data storage method, the @ Myredis annotation and the @ Update annotation are added to the redisAPI, data in the database with the @ Myredis annotation can be automatically stored in the redis cache only by one line of codes, and the data in the database with the @ Update annotation is synchronously updated in the redis cache, so that a large amount of redundant codes and development cost are reduced, the storage is convenient and rapid, codes interacting with the database are reduced, and the data in the database and the cache are consistent; furthermore, the invalidation time of the object in the redis cache can be automatically set, so that the consistency of the data and the cache data is further ensured; furthermore, the range of the updated data is determined according to the enumeration value in the parameter of the @ Update annotation, so that the range of the data Update is defined, the data Update time is saved, and the efficiency of the data Update is improved.
