Technical Field
The invention belongs to the technical field of databases, and particularly relates to a method and a device for generating a service order number.
Background
In the e-commerce property platform, the generation logic of the unique order number is not bypassed. In the early stage of platform development, under the background of low single quantity, the generation algorithm of single numbers generally does not cause the problem of generating the same single number. However, under the condition that the single number is increased at a high speed as the platform is rapidly developed, the serious problem of generating the same single number can be avoided only by optimizing and upgrading and gradually iterating the order number generation algorithm. Techniques for implementing uniqueness include algorithms based on time stamps and fixed prefixes, and also methods based on random number generation.
Order number encoding methods based on a time stamp and a fixed prefix, which use the time stamp as part of the order number and add a fixed prefix or suffix before or after the time stamp. However, due to the accuracy limitations of the time stamps and the limited nature of the fixed prefix or suffix, there is still the risk that different members and different product lines will generate the same order number. An order number encoding method based on a random number, which uses a random number as a part of an order number to increase the uniqueness of the order number. However, the generation of random numbers may have a possibility of repetition, and the uniqueness of the order number cannot be fully ensured. The prior art has the risk of generating the same order number by the same member and the same product line, and the uniqueness and the efficiency of generating the order number are also challenged under the high concurrency condition.

Locks ensure the risk of concurrency. And extracting the encrypted member code and business line code of the data packet. And inserting a record into a table with the self-increasing main key and the creation time field with the unique constraint, returning the main key ID, and generating a retry mechanism with failure. After the main key ID is obtained, the system time, the product line, the Hash value of the member number and a section of random number are spliced into a character string, an order unique number is generated, and then the character string is inserted into a table with the order number as the unique main key, so that the uniqueness of the order number is ensured.

Fig. 1 is a main flow chart of the technical scheme of the present invention. As shown in fig. 1, the method for generating an order unique number across service lines provided by the invention comprises the following steps:
(1) Newly built in a database are an automatic adding main key table (table 1) and a single number unique table (table 2), and the data structures of the two tables are as follows:
self-increasing primary key table: ID field, time field. The ID field is an auto-increment key, and the step size is 1. The time field is accurate to the millisecond level and sets a unique constraint.
Single number unique table: order number field. This field is set to the primary key.
(2) Firstly, the pre-generated order number is tried to be obtained from the cache, and if the pre-generated order number is obtained, the pre-generated order number is directly returned to the service end.
(3) In step (2), after no order number is obtained, the redis distributed lock is obtained. Only one request is allowed to generate an order number. The same order number is generated in case of high concurrency is prevented. And if the request of the distributed lock is not acquired, entering a waiting state.
(4) A record is inserted into table 1 and the primary key ID is returned. With the auto-increment primary key feature of the MSSQL database table, the ID column automatically increases from 1, i.e., 1, 2, 3, 4, for each record inserted. When the sql statement is written in the program, the time field is assigned with the value: dateTime. Now. ToString ("yyyy-MM-dd HH: MM: ss. Fff"). If the insertion fails, retry. The uniqueness of the time field in table one further ensures the uniqueness of the data.
(5) And (3) splicing the main key ID returned in the step (4) and other metadata. The specific rules are as follows:
product line number + current time (accurate millisecond) +membership ID + Gui hash value multiplied by current seconds is used as a random number seed, and the random number + self-increasing primary key ID is taken from 10-99.
Product line number: in the business system, codes of various product lines, such as hotel 1, air ticket 2, train ticket 3, etc., are predefined.
The current time: to the nearest millisecond, the value format is DateTime. Now. ToString ("MMddssff"), such as: 07273779.
membership ID: such as 93.
Random number: the hash value of the GUID multiplied by the number of timing cycles at the current time is used as the seed value of the random number, and then a value is randomly taken from 10 to 99. Such as: 35.
self-increasing primary key ID: the auto-increased primary key ID value of table 1. Such as: 100.
according to the above rule, the generated cases are: 2072737799335100.
if the length of the order number spliced above exceeds 25, the character string with the length of 25 is reserved by cutting from the end.
The order number fields in the service line are all provided with indexes, so that the efficiency of searching according to the order numbers is improved.
(6) Inserting the order number generated in the step (5) into the table (2), and verifying whether the generated order number is unique by using a field primary key unique mechanism. If the insertion is successful, the redis queue is written. Otherwise, regenerating the order number.
(7) Repeating the steps (4) to (6). In order to improve the efficiency of acquiring order numbers, the order numbers are pre-generated in batches each time and put into a redis queue for subsequent requests.
It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate technical solution, and this description is for clarity only, and those skilled in the art should consider the disclosure as a whole, and the technical solutions of the embodiments may be combined appropriately to form other embodiments that can be understood by those skilled in the art.
