102, obtaining configuration parameters in a preset configuration file, wherein the configuration parameters comprise a first maximum sequence number and a queue length.
According to the invention, the preset number of serial numbers are generated, and the unique serial numbers under distributed deployment can be generated through the configuration parameters in the preset configuration file without depending on other software and applications.
The configuration parameters in the file include a first maximum sequence number and a queue length, the number of sequence numbers generated at one time can be determined according to the queue length, if the queue length is 100, 100 sequence numbers are generated, the first maximum sequence number is the maximum sequence number in the system in the current state, the maximum sequence number is identified by cur _ max, and when cur _ max is 100000000, it indicates that the maximum sequence number in the distributed system is 100000000 at this time.
Optionally, the configuration parameters further include a sequence initial value; generating a preset number of sequence numbers according to the configuration parameters, including:
and under the condition that a preset number of sequence numbers are generated according to the configuration parameters for the first time, taking the sequence initial value as a first maximum sequence number.
In practical applications, the configuration parameters further include a sequence initial value, and if the sequence initial value is set to 100000000, it indicates that the sequence numbers are counted from 100000000, and when a preset number of sequence numbers are generated for the first time, the sequence initial value is the first maximum sequence number, that is, when the preset number of sequence numbers are generated for the first time, the sequence numbers are generated based on the sequence initial value.
And 104, generating a preset number of sequence numbers according to the first maximum sequence number and the queue length, and determining a second maximum sequence number, wherein the preset number is the same as the queue length.
Specifically, a preset number of sequence numbers can be generated according to the first maximum sequence number and the queue length, the queue length is a preset number value, if the queue length is 100, 100 sequence numbers are generated, if the queue length is 200, 200 sequence numbers are generated, and at this time, the second maximum sequence number can be determined according to the first maximum sequence number and the queue length.
After the second maximum sequence number is generated with the preset number of sequence numbers, the maximum sequence number existing in the system still takes the first maximum sequence number as 100000000, and the queue length as 100, and then 100 sequence numbers are generated, and at this time, the second maximum sequence number is 100000100.
And 106, updating the first maximum sequence number in the configuration file according to the second maximum sequence number.
Specifically, the second maximum sequence number is updated to the first maximum sequence number in the configuration file, which indicates that the maximum sequence number in the system is the second maximum sequence number.
Following the above example, the first maximum serial number is 100000000, and when the preset number of serial numbers are generated, the second maximum serial number is 100000100, at this time, 100000100 is updated to the configuration file, and 100000000 is updated to 100000100.
And step 108, sequentially acquiring a target serial number corresponding to the current program call from the preset number of serial numbers according to the program call times.
And sequentially acquiring the sequence number corresponding to the current program call from the generated sequence numbers according to the times of the program calls, wherein if the sequence number is 100000000 to 100000100 when the sequence number is a preset number, the sequence number corresponding to the first program call is 100000001, the sequence number corresponding to the second program call is 100000002, and so on.
Optionally, the configuration parameters further include a machine identifier;
sequentially acquiring a target sequence number corresponding to the current program call from the preset number of sequence numbers according to the program call times, wherein the method comprises the following steps:

and generating a target serial number corresponding to the current program call according to the initial serial number and the machine identifier.
In practical application, the configuration parameters of the configuration file further include a machine identifier, for example, the machine identifier is 01, the serial number corresponding to the current program call is the initial serial number, and then the initial serial number and the machine identifier are combined to generate a target serial number, the target serial number of the first program call is 01100000001, the target serial number of the second program call is 01100000002, and so on.
Optionally, after step 108, the method further includes:
counting the program calling times, and executing the steps 102 to 108 when the program calling times are larger than the queue length.
Counting the number of calls after each program call, indicating that the pre-generated sequence number is not used up when the number of calls is less than or equal to the queue length, and continuing to use the program, and executing the operation of step 102 again when the number of calls is greater than the queue length, generating a new preset sequence number, updating the new maximum value of the queue to the current maximum value of the queue, and executing the operations of steps 102 to 108 in a circulating manner.
