s101: and judging whether a cache rule exists in the cache system.
That is, when the external system searches and matches data in the cache system, the external system first obtains the preset cache rule and corresponding data from the cache system to determine whether the corresponding cache rule exists. And executing corresponding operation according to whether the corresponding cache rule exists. The cache rule refers to a specific rule for searching, matching or obtaining data in a cache system, and if only data related to A, B parameters are searched, only A, B parameters are configured; if data related to the A, B, C parameters is found, the A, B, C parameters need to be reconfigured.
S102: and if so, matching data from the cache system according to the cache rule.
Namely, if the cache rule can be successfully acquired from the cache system, data search or data matching is performed from the cache system according to the cache rule. The specific process of data search or data matching from the cache system in the present application is as follows:
firstly, data is taken from a cache system; then, converting the acquired data into a hash code (HashCode) according to the acquired caching rule; then matching the hash codes according to a caching rule; if the matching is successful, returning a matching value; if the failure occurs, the next step is performed, namely, rule data is acquired from the outside. The acquiring of the rule data from the outside may include acquiring the corresponding rule data in a preset path or passively accepting rule data incoming from the outside.
S103: if not, the data and rule data are obtained from the outside.
That is, if the corresponding cache rule cannot be obtained from the cache system, data and rule data for specifying the cache rule of the cache system, that is, the cache rule of the cache system is specified, are obtained from the outside. The method specifically comprises the following operations:
firstly, judging whether a cache rule changes; if the rule data are changed, updating the rule data and storing the updated cache data into the cache system, wherein the updating means that the original rule data are covered by new rule data, and the new rule data prescribe a new cache rule, so that the system can operate according to the new cache rule when caching the data; on the contrary, if there is no change, the acquired data and rule data are directly stored in the cache system, and the new rule data is made unavailable.
S104: and storing the data and the rule data into a cache system.
After acquiring corresponding rule data from the outside, the rule data is stored in the cache system, so that a user can search data or match data according to the cache rule specified by the rule data when the user requests the data.
As can be seen from the foregoing technical solutions, the present embodiment provides a rule configuration method for a cache system, where the method specifically includes determining whether a cache rule exists in the cache system; if yes, performing data matching from the cache system according to the cache rule; if not, acquiring data and rule data from the outside; and storing the data and the rule data into a cache system. Through the process, the cache rule in the cache system can be automatically updated, and the manual configuration of the cache rule is not needed again, so that the development cost is reduced.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
