In this embodiment, before the third step is performed, the request path of the user side is switched from the redis cache to the database, and after the third step is completed, the request path of the user side is switched from the database to the redis cache.
The second aspect of the present invention discloses a hotel information updating apparatus based on redis, comprising: the device comprises a timing acquisition module, a first information updating module and a second information updating module;
the timing acquisition module is used for acquiring hotel information at preset time intervals;
the first information updating module is used for updating the hotel information acquired by the timing acquisition module into a database;
and the second information updating module is used for storing the updated hotel information in the database into a redis cache.
The hotel information updating device based on redis further comprises a path switching module, wherein the path switching module is used for switching the request path of the user side from the redis cache to the database when the second information updating module is about to operate, and switching the request path of the user side from the database to the redis cache after the second information updating module operates.
In a third aspect of the present invention, a terminal device is disclosed, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, and when the processor executes the computer program, the steps of the hotel information updating method are implemented.
A fourth aspect of the present invention discloses a computer-readable storage medium, which stores a computer program, which, when executed by a processor, implements the steps of the hotel information update method as described above.
Compared with the prior art, the invention has the following advantages: according to the invention, the hotel information is updated to the redis cache while being updated to the database at regular intervals, so that the accuracy of the hotel information is ensured, the instantaneous pressure of the database is reduced, and the stability of a hotel system is ensured.
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.
Drawings
Fig. 1 is a flowchart of a hotel information updating method according to the present invention.
Fig. 2 is a schematic diagram of the hotel information update apparatus of the present invention.
Detailed Description
As shown in fig. 1, a method for updating hotel information based on redis includes:
step one, acquiring hotel information at preset time intervals;
the method comprises the steps of setting a timing task, obtaining hotel information once from a third-party server at intervals of preset time, wherein the hotel information mainly comprises room information and room price information, and obtaining the hotel information once at intervals of preset time can ensure that the hotel information has certain real-time performance and can reduce access times to a database and the third-party server.
Step two, updating the acquired hotel information into a database;
and step three, storing the updated hotel information in the database into a redis cache.
The hotel information in the database is mainly used for user side query, but in order to improve user experience, the opening speed of a user side page is improved, updated hotel information in the database is stored into a redis cache by additionally arranging the redis cache, so that the speed is higher when the user side queries, the database is prevented from being directly accessed, and the pressure of the database is reduced.
In this embodiment, before the third step is performed, the request path of the user side is switched from the redis cache to the database, and after the third step is completed, the request path of the user side is switched from the database to the redis cache.
By switching the request path of the user side, the accuracy of the information inquired by the user side is ensured, and the fraud problem caused by the inconsistency between the price information inquired by the user and the actual price information is avoided.
As shown in fig. 2, a hotel information updating apparatus based on redis includes: the device comprises a timing acquisition module, a first information updating module and a second information updating module;
the timing acquisition module is used for acquiring hotel information at preset time intervals;
the timing acquisition module sets a timing task, acquires hotel information once from the third-party server at intervals of preset time, the hotel information mainly comprises room information and room price information, and the hotel information acquired at intervals of preset time can ensure that the hotel information has certain real-time performance and can also reduce the access times to the database and the third-party server.
The first information updating module is used for updating the hotel information acquired by the timing acquisition module into a database;
and the second information updating module is used for storing the updated hotel information in the database into a redis cache.
The hotel information in the database is mainly used for user side query, but in order to improve user experience, the opening speed of a user side page is improved, updated hotel information in the database is stored into a redis cache by additionally arranging the redis cache, so that the speed is higher when the user side queries, the database is prevented from being directly accessed, and the pressure of the database is reduced.
In this embodiment, the hotel information updating apparatus further includes a path switching module, where the path switching module is configured to switch the request path of the user side from the redis cache to the database when the second information updating module is about to operate, and switch the request path of the user side from the database to the redis cache after the second information updating module finishes operating.
By switching the request path of the user side, the accuracy of the information inquired by the user side is ensured, and the problem of fraud caused by inconsistency between the price information inquired by the user and the actual price information is avoided
A terminal device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, the processor implementing the steps of the hotel information updating method as described above when executing the computer program.
A computer-readable storage medium, storing a computer program which, when executed by a processor, implements the steps of the hotel information update method as described above.
