In addition, the long-time cache file and the short-time cache file are cached in the server, and the client can fetch the files according to the requirement, so that the data caching pressure of the client can be reduced.
In some embodiments, the data of the long-time cached file is: dictionary data such as: gender, address, etc.; the data of the short-time cache file are: traffic data, such as: certificate type, drug catalog, medical record type, etc.
Step S11, loading the long-time cache file and the short-time cache file by matching different cache strategies;
Specifically, the long-time cache file is matched with an initial cache strategy, and is loaded when the service of the system is released;
And matching the short-time cache file with an initial cache policy, and loading the short-time cache file when the system is used.
It should be noted that, the long-time cache file is loaded when the system service is released, and the short-time cache file is loaded when the system is used, so that the pressure of the database is reduced, the related data is prevented from being modified after being preloaded, and the latest data is needed to be reloaded when the system is actually used, so that the pressure of the database is increased.
Step S12, the loaded long-time cache files and the loaded short-time cache files are distributed to different cache pools, wherein each cache pool comprises a long-time cache pool and a short-time cache pool, the long-time cache files are distributed to the long-time cache pool, and the short-time cache files are distributed to the short-time cache pool;

if yes, the short-time cache file does not need to be reloaded and updated;
If not, reloading and updating the short-time cache file.
It should be noted that, through setting up of different update intervals, timely update of the cache data and integrity of the cache data will be ensured, pressure of the database is reduced, and obtaining efficiency of the cache data is improved.
In some embodiments, the second update sub-interval may be, for example, 4min,5min,6min, etc., and the second update sub-interval may be, for example, 9min,10min,11min, etc.

and the cache pool sends a feedback code to the client, and when the client verifies that the verification code is consistent with the feedback code, the long-time cache file or the short-time cache file of the cache pool is obtained by unlocking.
In some embodiments, the client performs consistency judgment on the feedback code and the check code, if the front check code and the back check code are consistent, the client indicates that the long-time cache file or the short-time cache file of the cache pool is acquired as available data, and the client can directly use the available data; if the front check code and the back check code are inconsistent, the long-time cache file or the short-time cache file of the cache pool is obtained, and the client needs to execute calling operation to obtain the long-time cache file or the short-time cache file again.
In addition, when the client calls the long-time cache file or the short-time cache file in the server, a check code is generated to access the cache pool according to the type, the cache policy and the update policy, which specifically includes:
When the client calls the long-time cache file or the short-time cache file in the server, a character string is generated according to the type, the cache policy and the update policy;
it should be noted that, the client may also choose not to update the cached data, directly use the original long-time cached file and short-time cached file, and improve the user experience.
In some embodiments, the types include a long-time cache file and a short-time cache file, for example, 01 and 02 characters can be respectively assigned, a buffer update policy can be for example, 01 represents that no cache data is updated, 02 represents that a short-time cache pool is not called after a second update subinterval, the short-time cache file is reloaded and updated, 03 represents that the short-time cache pool is not required to be reloaded and updated when the time of calling and loading exceeds the second update subinterval, 04 represents that the short-time cache pool is not required to be called and loaded after the time of calling and loading exceeds the second update subinterval and does not exceed the second update subinterval, and the like, and the short-time cache pool is arranged and combined to form a character string.
And carrying out Kaiser password encryption on the character string to obtain a first ciphertext, adding a timestamp, carrying out Base64 operation to obtain a second ciphertext, and carrying out MD5 encryption on the second ciphertext to obtain a check code.
The setting of the check code can improve the safety of the database, realize the synchronization of the database, and meanwhile, the verification of the check code can improve the integrity and the accuracy of the update synchronization of the data.
