Serial number generation method and system

Abstract

The embodiment of the invention provides a serial number generation method and system, and the method comprises the steps: responding to a serial number generation request through gateway equipment, obtaining a business code, and generating a timestamp according to the system time when the serial number generation request is received; and enabling the service node to obtain the serial number of the serial number generation request under the timestamp, and generate the serial number corresponding to the serial number generation request according to the service code, the timestamp, the pre-generated node code and the serial number. In this way, the generation of the timestamp is carried out in advance to the gateway equipment, the gateway equipment uniformly generates the timestamp, and eachservice node generates the serial number based on the timestamp generated by the gateway equipment, so that the uniqueness of the time information source of each serial number is ensured, and the problem of time asynchronization of different service nodes is solved. Moreover, the generated serial number contains the service information, so that the inverse solution of the subsequent service information is facilitated.

Description

technical field [0001] The present application relates to the technical field of distributed systems, and in particular, to a serial number generation method and system. Background technique [0002] In many application scenarios, such as network transaction scenarios, it is necessary to generate a unique serial number for each transaction or business to record the business or transaction. Currently, there are many ways to generate the serial number, and the generated serial number also has many different forms. At present, a better way is to use the distributed system to generate the serial number, but in the prior art, when the distributed system is used to generate the serial number, due to the fluctuation of the clock oscillation frequency of the central processing unit (Central Processing Unit, CPU) of each service node It is difficult to fully synchronize the time between different service nodes, resulting in duplication of generated serial numbers, which has a seriou...

Problems solved by technology

At present, a better way is to use the distributed system to generate the serial number, but in the prior art, when the distributed system is used to generate the serial number, due to the fluctuation of the clock oscillation frequency of the central processing unit (Central Processing Unit, CPU) of each service node Differences, the time between different service nodes is difficult to fully synchronize, resulting in the possibility of duplication of generated serial numbers, which has a serious impact on business

Moreover, the generated serial number lacks business information and is not easy to understand
