Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic diagram of a serial number application system provided in the present invention. As shown in fig. 1, the system includes a terminal device 101, a terminal device 102, and a server 103, where the server 103 may also be a server cluster. The user can send a request to the server through the terminal device 102 and the terminal device 102 to generate the serial number, the server 103 can obtain the identifier of the serial number pool of the user after receiving the request, further sequentially generate the offset according to the current sequence position of the serial number pool, and assemble the identifier of the serial number pool and the offset into the serial number according to the preset rule, and the uniqueness of the generated serial number can be ensured due to the uniqueness of the identifier of the serial number pool and the offset. The following describes an example of a serial number generation method provided by the present invention with reference to an embodiment.

Fig. 2 is a schematic flow chart of a serial number generation method provided in the present invention. The method may be performed by a server in the system shown in fig. 1. As shown in fig. 2, the method includes:

s201, obtaining an identifier of the serial number pool, wherein the identifier is used for uniquely marking the serial number pool.

The server may have at least one sequence number pool therein, each sequence number pool having a unique identifier to distinguish it from other sequence number pools. The serial number pool can be created by a serial number pool generation module that creates several pools of serial number objects in a single resource, such as a database or a redis, for example. Each serial number pool has a space for storing serial numbers, which is created when the serial number pool is initialized. As shown in fig. 3, each sequence number pool includes a plurality of sequence number arrays, each sequence number array includes a plurality of sequence number blocks, and each sequence number block stores a sequence number. If the space of the serial number pool is full, a new serial number pool can be automatically created, and the new serial number pool can be uniquely marked according to the time stamp of the natural day and the precision of the time stamp of the natural day to millisecond. It can be understood by those skilled in the art that the serial number pool may also be uniquely marked by using other identifiers, which is not limited in this embodiment. Taking the identifier of the serial number as the unique timestamp as an example, the identifier of the serial number pool is obtained as 20190707221123234.

S202, generating offsets in sequence according to the current sequence position of the sequence number pool.

The offset is generated in each sequence number pool according to the sequence, the current sequence position is the offset of the sequence number generated last time, for example, the current sequence position is 23456, that is, the offset of the sequence number generated last time is 23456, and then the offset generated according to the sequence when the sequence number is generated this time is 23457. Because the offsets are generated in sequence, the offset obtained in the serial number pool at each time can be guaranteed to be unique.

S203, assembling the identification and the offset of the serial number pool into a serial number according to a preset rule.

The preset rules can be set according to actual needs, for example, the assembly sequence of serial numbers, the addition of preset fixed character strings, and the like can be set. For example, the sequence numbers 2019070722112323423457 are obtained by splicing according to the sequence of the serial number pool identification and offset. Because the mark of the serial number pool is unique and the offset in the serial number pool is also unique, the serial number can be ensured to be unique. The sequence number generated after completion of assembling is marked as invalid after being extracted and sent to the application requester requesting the sequence number.

In the serial number generation method provided by this embodiment, an identifier of a serial number pool is obtained, where the identifier is used to uniquely mark the serial number pool; sequentially generating offsets according to the current sequence position of the serial number pool; and assembling the identification and the offset of the serial number pool into a serial number according to a preset rule. Because the identification of the serial number pool is unique, the offset of each production in the serial number pool is also unique, thereby ensuring the uniqueness of the serial number obtained by splicing the identification and the offset of the serial number pool and avoiding the occurrence of abnormity of various applications depending on the uniqueness of the serial number.

On the basis of the foregoing embodiment, since there may be a plurality of serial number pools in the server, before obtaining the identifier of the serial number pool in S201, the method further includes:

selecting the sequence number pool from at least one target sequence number pool; the current sequence position of the sequence number pool is locked.

The number of the sequence number pools in the server may be multiple, when the server generates the sequence number, one available sequence number pool is selected from the multiple sequence number pools, for example, if a sequence number space of one sequence number pool is filled, the sequence number pool is not available, one sequence number pool is selected from the available sequence number pools as the sequence number pool for generating the sequence number this time, for example, one sequence number pool may be randomly selected from the multiple available sequence number pools. After the sequence number pool is selected, the current sequence position of the current sequence number pool is locked, so that the sequence number repetition caused by other requests using the current sequence position of the sequence number pool to carry out sequence generation offset can be avoided.

In one possible approach, the generating the offset in S202 according to the current sequence position of the sequence number pool in sequence includes:

and generating the offset in sequence according to the current sequence position of the sequence number pool in the offset interval which is pre-allocated to the sequence number pool.

Each sequence number pool has an offset interval, i.e. a fragment interval of an offset, and when generating a sequence number, the offset is sequentially taken from the fragment interval. For example, the offset of the sequence number pool is 00001-99999, so that the offset of the sequence number generated by the sequence number pool is from 00001, and is sequentially increased by 1 to 99999.

Optionally, the offset interval of the sequence number pool may be obtained from a global database or redis to ensure that there is no duplicate value in the offset interval of each sequence number pool, and the start value of the offset interval may be obtained when the sequence number pool is initialized or a new sequence number pool is generated. Further, each sequence number pool may also have a machine number that is used to mark which virtual machine or which container node the sequence number pool owns. And recording the offset interval record acquired by the serial number pool of the virtual machine or the container node corresponding to each machine number, so as to conveniently and quickly locate the virtual machine or the container node on which a serial number is generated when a fault occurs or maintenance is carried out.

For example, if the offset interval obtained from the serial number pool of the container with the machine number 001 is 0 to 100 when the container is started, the offset when the serial number is generated will be automatically filled as: 00001. 00002, 00003 … until 00100 is filled. Since the offset interval obtained from the serial number pool of the 002 # container is 101-200 when the 002 # container is started from the global acquisition interval, the offset amount is automatically filled to 000101, 000102 and 000103 … until 00200 when the serial number is generated. At this time, the offset interval obtained again for container number 001 is: 201-.

In addition, in this embodiment, the servers may be in a cluster mode, and in the cluster mode, the machine number of each server is recorded in the memory and the database, where a server serial number and a network card MAC address are also recorded. If a node is dynamically expanded in the cluster mode, comparing whether the node is the existing record in the memory and the database, if not, re-allocating a new machine number for the dynamically expanded node and storing the new machine number, thereby ensuring the non-stop dynamic generation of the machine number in the cluster mode.

Correspondingly, assembling the identifier and the offset of the serial number pool into the serial number according to the preset rule in S203 may include:

sequentially splicing the identifier and the offset of the serial number pool and the machine number of the node where the serial number pool is located into a serial number;

the machine number of the node where the serial number pool is located corresponds to the offset interval of the serial number pool, and the offset interval of the serial number pool is not overlapped with the offset intervals of other serial number pools except the serial number pool.

For example, if the serial number pool is identified as 20190707221123234, the offset is 23457, and the machine number is 001, then the generated serial number is 2019070722112323423457001. The serial number generated in the embodiment not only guarantees the uniqueness of the serial number through the identification of the serial number pool and the uniqueness of the offset, but also improves the efficiency of problem location through the machine number carried in the serial number.

In practical application, an application requester requesting a serial number generation service may need to generate a custom serial number according to its own needs, and in order to implement a user-defined function, in S201, obtaining an identifier of a serial number pool may include: and determining the user-defined code as the identification of the serial number pool.

For example, a user-defined code can be configured in the custom configuration table as an identifier of the serial number pool, for example, the first five fixed numerical values of the school number are used as the user-defined code, and a value range of the offset can be configured, for example, the number of students is 1000, and the value range of the offset is 0001-1000, so that when the serial number is generated, the ascending operation can be automatically performed in the value range of the offset, the current latest sequence can be read in each ascending operation, then the ascending operation is performed on the specified number according to the rule, and the ascending uniqueness is ensured by using a thread safety cable mechanism. This allows 1000 serial numbers to be generated as student numbers, each unique.

Further, determining the user-defined code as an identifier of the serial number pool may further include:

executing a preset script to obtain a dynamic code defined by a user; the dynamic code is determined as an identification of a pool of sequence numbers.

The user-defined serial number may be dynamically loaded when the serial number is generated, for example, the user-defined code is a region code, a country code, or the like, in addition to the fixed code, and when the serial number is generated, the program execution script reads the current user-defined code.

On the basis of the above embodiment, assembling the identifier and the offset of the serial number pool into the serial number according to the preset rule in S203 includes:

and splicing the preset prefix and/or the preset suffix, the identification of the serial number pool and the offset into the serial number.

For example, an application requester using the serial number generation service needs to generate a serial number with its own flag, and assuming that the service abbreviation used by the application requester for the serial number is abc, and the application requester needs to embody the abbreviation in the serial number, the sequence number obtained by splicing abc as a prefix or a suffix can be spliced in the serial number, for example, the serial number pool is identified as 20190707221123234, and the offset is 23457, and then the sequence number obtained by splicing abc as a prefix is abc 2019070722112323423457.

The method can add prefix and/or suffix in the serial number according to the actual requirement of the serial number requester, thereby improving the practicability and diversity of the serial number.
