Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, 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 flow chart of a number generation method applied to a software system according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
s1, acquiring a first numerical value of the timestamp bit, a second numerical value of the self-increment bit and a third numerical value of the random bit at the current moment;
s2, generating the number of the target in the software system based on the first numerical value, the second numerical value and the third numerical value;
the first numerical value, the second numerical value and the third numerical value are data of a preset system, and the cardinal number of the preset system comprises numbers and letters or numbers, letters and special characters.
Specifically, in the method for generating a serial number applied to a software system provided in the embodiment of the present invention, the execution subject is the serial number generation system, the system may be configured in a server, the server may be a local server or a cloud server, and the local server may be a computer, a tablet computer, a smart phone, and the like. The number generation method provided by the embodiment of the invention can be applied to a software system to obtain the number of the target in the software system, and the target can be identified through the number so as to be tracked, inquired, searched and the like subsequently. The software system may be an order system, a flow system, or the like, may also be a system for storing and managing information of the machine device, and may also be a database system, and the like, which is not specifically limited in the embodiment of the present invention. Accordingly, the target may be an order, a pipeline, a machine device, a database data, and the like. Further, the number of the object may be an order number, a serial number, a machine device identification, a database primary key (index), and the like.
Step S1 is executed to obtain a first value of the timestamp bit, a second value of the self-increment bit, and a third value of the random bit at the current time. Here, the current time is the time at which the number is generated.
The composition structure of the number may include timestamp bits, self-increment bits, and random bits, and the positions of the timestamp bits, the self-increment bits, and the random bits in the number may be set as needed, for example, the timestamp bits, the self-increment bits, and the random bits may be arranged according to the order of the timestamp bits, the self-increment bits, and the random bits, or the timestamp bits, the self-increment bits, and the random bits may be arranged in other random orders, which is not specifically limited in this embodiment of the present invention.
The first numerical value of the timestamp bit is used for representing the timestamp of the current moment, the timestamp can be accurate to the second, the serial number of production can be guaranteed to have the time sequence, and the target can be conveniently and rapidly inquired.
The second value of the incremental bits is used for representing the incremental data of the current moment, the second value can be incremented in a single second, and the increasing form can be set according to needs, for example, the second value can be continuously increased or discontinuously increased, that is, for two codes which are successively and continuously generated, the number in a random system is increased on the basis that the second data of the incremental bits of the first code which is generated later is the second data of the incremental bits of the second code which is generated earlier.
The third value of the random bit, which is used to characterize the random data at the current time, completely avoids identically numbered collisions within a single second.
In order to reduce the length of the generated number, the carry numbers of the first numerical value, the second numerical value and the third numerical value may be set as preset carry numbers, that is, the first numerical value, the second numerical value and the third numerical value are data of the preset carry numbers. The preset scale can be set according to needs, and the base number of the preset scale comprises numbers and letters or numbers, letters and special characters.
When the base number of the preset scale includes a number and letters, since the number is 10, the letters include 26 upper case letters and 26 lower case letters, and there are 52 letters. Therefore, the maximum preset scale may be 62, and the value of the preset scale may be adjusted by increasing or decreasing the base number of the preset scale.
When the predetermined base number includes numbers, letters and special characters, since the numbers have 10, the letters include 26 upper case letters and 26 lower case letters, and there are 52 in total, and the special characters may have 26. Therefore, the highest preset system can be an 88 system, and the value of the preset system can be adjusted by increasing or decreasing the base number of the preset system.
Taking the preset scale as 62 scale as an example, the base number may include 62 elements, such as 10 digits, 26 small-case letters, and 26 large-case letters. I.e., its cardinality may include: "0123456789 abcdefghijklmnorqtuwxyzABCDEFGHIJKLMNOPQRSTHUVXYZ".
Taking the preset scale as 88 scale as an example, the base number may include 88 elements, such as 10 digits, 26 lower case letters, 26 upper case letters, and 26 special symbols, that is: "0123456789 abcdefghijklmnopqrstuvxyz! @ # $% & () - + ═ { } [ ] | \/? < > ".
Because the number system of the serial number is adjustable, the n system can be switched into the m system at will by increasing or decreasing the base number. Because of the n-system radix code table, a new code table can be generated by randomly disordering the sequence on the premise of not increasing or decreasing the radix, so that theoretically the n-system total n! The (factorial) seed code table enriches the code table.
Then, step S2 is executed to automatically generate a number of the target in the software system according to the first value of the timestamp bit, the second value of the self-increment bit and the third value of the random bit. The timestamp bits, the self-increment bits and the random bits all correspond to fixed bit numbers, so that when the numbers are automatically generated, the first numerical value, the second numerical value and the third numerical value can be expressed by the bit numbers of the corresponding bits, and the numbers of the targets in the software system can be obtained.
The serial number generation method applied to the software system provided by the embodiment of the invention comprises the steps of firstly obtaining a first numerical value of a timestamp bit, a second numerical value of a self-increment bit and a third numerical value of a random bit at the current moment; then generating a number of the target in the software system based on the first numerical value, the second numerical value and the third numerical value; the first numerical value, the second numerical value and the third numerical value are data of a preset system, and the preset system comprises a 62 system or an 88 system. By setting the timestamp bit, the obtained number has time sequence, and the target can be conveniently and rapidly inquired. By setting the self-increment bit, the number can be ensured to be increased within a single second. By setting random bits, the same numbering within a single second can be avoided. In addition, because the first numerical value, the second numerical value and the third numerical value are data in 62-system or 88-system, the length of the number can be greatly shortened, the number of the numbers which can be generated can be increased, and the method can be suitable for a system with a large number requirement.
On the basis of the foregoing embodiment, the number generation method applied to the software system provided in the embodiment of the present invention generates a number of a target in the software system based on the first numerical value, the second numerical value, and the third numerical value, and before that, the method further includes:
acquiring a fourth numerical value of the number of accumulated downtime at the current moment, wherein the fourth numerical value is data of the preset system;
correspondingly, the generating a number of the target in the software system based on the first numerical value, the second numerical value, and the third numerical value specifically includes:
generating the number based on the first, second, third, and fourth numerical values.
Specifically, in the embodiment of the present invention, before generating the number of the target in the software system, a fourth numerical value of the number of the accumulated downtime at the current time may also be obtained. And the fourth numerical value of the downtime accumulated number is used for representing the downtime accumulated number of the numbering generation system before the current moment.
The position of the downtime accumulation number in the number may be set according to needs, for example, the downtime accumulation number may be set after the random bit, or may be set in any position.
It should be noted that the fourth value, the first value, the second value, and the third value are data of a preset system, so that consistency of numbered system numbers can be ensured.
Thereafter, when generating the number of the target in the software system, the number may be generated according to the first numerical value, the second numerical value, the third numerical value, and the fourth numerical value. Because the number of the downtime accumulated times is also corresponding to the fixed bit number, when the number is automatically generated, the first numerical value, the second numerical value, the third numerical value and the fourth numerical value can be expressed by the bit number of the corresponding bit at the same time, and the number of the target in the software system can be obtained.
In the embodiment of the invention, the downtime state of the number generation system can be early warned through the fourth numerical value of the number of the downtime accumulated times, so that a user can master the working state of the number generation system by checking whether the fourth numerical value of the number of the downtime accumulated times changes. Moreover, the accumulated number of times of downtime is different before the system is crashed by numbering generation and during the restarting operation after the system is crashed, so that the phenomenon of time rollback caused by the system crashed by numbering generation can be further prevented. The method can be applied to a master multi-slave cluster to prevent the numbering generation system from being down and being incapable of providing services to the outside.
On the basis of the above embodiment, the number generation method applied to the software system provided in the embodiment of the present invention further includes:
monitoring the working state of the serial number generation system to obtain a monitoring result;
if the monitoring result is that the serial number generation system is in a downtime state, adding 1 to the downtime accumulated times to obtain new downtime accumulated times;
and when the serial number generation system is restarted, taking the new downtime accumulated times as a fourth numerical value of the downtime accumulated times.
On the basis of the foregoing embodiment, in the number generation method applied to the software system provided in the embodiment of the present invention, the number of bits of the timestamp bits, the self-incrementing bits, the random bits, and the total number of times of downtime is determined based on the following method:
determining a target number of bits of the number;
and determining the bit number of the timestamp bits, the self-increment bits, the random bits and the downtime accumulated number of bits based on the target bit number and the preset scale.
Specifically, in the embodiment of the present invention, when determining the bit numbers of the timestamp bits, the self-increment bits, the random bits, and the downtime accumulated number of bits, the target number of bits of the serial number may be determined first. The target number of bits may be set by the user as desired, and may be set to 12, 15, or the like, for example.
And then, according to the target digit and a preset system, determining the bit digits of the timestamp digit, the self-increment digit, the random digit and the downtime accumulated number digit. The bit digits of the timestamp bits, the random bits and the downtime accumulated number of bits can be fixed values given by a user according to values of a preset scale, and then the self-increment bit digits are obtained based on the target digit, the given timestamp bits, the given random bits and the bit digits of the downtime accumulated number of bits.
In the embodiment of the invention, the target digit of the number needs to be determined firstly, so that the length of the number can be adjusted, and the length can be completely adjusted according to the specific actual condition.

Specifically, in the embodiment of the present invention, the timestamp bits, the random bits, and the number of bits of the downtime accumulated number of bits may be given by the user in advance according to actual needs under the condition of determining the preset scale. Thereafter, the number of bits to self-increment is determined by calculating the difference between the target number of bits and the number of bits of the timestamp bits, the random bits, and the downtime accumulated number of bits. For example, if the preset scale is a 62 scale, the bit number of the timestamp bit may be 7, the bit number of the random bit may be 3, the bit number of the downtime accumulated number of bits may be 1, the target number of bits is n (n > 11), and if the self-increment bit number is n-7-3-1.

Specifically, in the embodiment of the present invention, the timestamp bits, the random bits, and the number of bits of the downtime accumulated number of bits may be given by the user in advance according to actual needs under the condition of determining the preset scale. Thereafter, the number of bits to self-increment is determined by calculating the difference between the target number of bits and the number of bits of the timestamp bits, the random bits, and the downtime accumulated number of bits. For example, if the predetermined scale is 88, the number of bits of the timestamp bit may be 7, the number of bits of the random bit may be 3, the number of bits of the downtime accumulated number of bits may be 1, the target number of bits is n (n > 10), and if the number of bits of the self-increment is n-7-3-1.
