The generation of order numbers under a distributed system needs to satisfy the following six characteristics: 1. uniqueness: non-repeatable, unique identification; 2. increment: order numbers need to be added in order, and the next order number must be larger than the previous order number; 3. safety: the order numbers can not be continuous, thus preventing malicious stealing; 4. high efficiency: the generation of the order number needs low consumption and meets the high concurrency requirement; 5. the storage is convenient: easier to store and identify; 6. distributed: and high concurrency requirements of a distributed system are met.
The characters of the existing UUID are long, 36 characters are totally formed, and the UUID is not easy to store and index in a database.
Based on this, the method and the device for generating the order number by the distributed architecture provided by the embodiment of the invention can satisfy the six characteristics.
To facilitate understanding of the embodiment, a detailed description is first given of a method for generating an order number in a distributed architecture disclosed in the embodiment of the present invention.
The embodiment of the invention provides a method for generating an order number by a distributed architecture, which is shown in a flow chart of the method for generating the order number by the distributed architecture in figure 1, and comprises the following steps:
in step S102, date data is acquired.
In the embodiment of the present invention, the date data may be a system date, and may be represented in a "YYYYMMDD" format, where "YYYY" represents a year, "MM" represents month data, and "DD" represents date data.
Step S104, determining the bit number of the self-increment ID.
In an embodiment of the present invention, the self-increment ID includes machine code information, time stamp information, serial number information, and security code information. The bit number of the self-increment ID can be obtained by respectively determining the bit number required for expressing the machine code information, the timestamp information, the serial number information and the security code information.
For example, in the embodiment of the present invention, referring to the bit number structure diagram of the self-increment ID shown in fig. 2, the time stamp bit number may be determined to be 27 bits, the machine code bit number may be set to be 8 bits, the serial number bit number may be set to be 5 bits, and the security code bit number may be set to be 10 bits, so that the bit number of the self-increment ID is the sum of the above-mentioned several bits, and is 50 bits.
And step S106, generating a machine code, a time stamp, a serial number and a safety code according to the bit number of the self-increment ID.
In the embodiment of the invention, the machine code is used for representing the machine position information or the machine address information in the distributed system and is used for ensuring the safety in the distributed system. The time stamp is used to describe the duration of the current time from a specified time, and thus, the time stamp has an incremental nature. The sequence numbers are sequentially increased within a certain range, for example, if the sequence numbers include 5 bit numbers, that is, 32 sequence numbers are supported, the 32 sequence numbers are sequentially increased. The range of the sequence number depends on the number of bits it comprises. The security code is used to guarantee the discontinuity of order numbers and prevent malicious stealing.
Step S108, combine date data, machine code, time stamp, serial number and security code to generate order number.
In the embodiment of the invention, the order number can be obtained by splicing the machine code, the timestamp, the serial number and the security code and then combining the spliced machine code, the timestamp, the serial number and the security code with date data. It should be noted that the machine code, the timestamp, the serial number, and the security code may be concatenated in any order.
The embodiment of the invention provides a method for generating an order number by a distributed architecture, which comprises the steps of firstly acquiring date data, then obtaining the bit number of a self-increment ID by determining the bit number of a machine code, the bit number of a timestamp, the bit number of a serial number and the bit number of a safety code, obtaining the bit number of the self-increment ID, namely obtaining the selectable range of the machine code, the timestamp, the serial number and the safety code, and combining the machine code, the timestamp, the serial number, the safety code and the date data to obtain the order number with uniqueness. The embodiment of the invention can ensure the increment of the order number after being combined with the time stamp because the serial number has the increment, and ensures the safety because the safety code is discontinuous and the obtained order number is discontinuous, and ensures the generation efficiency of the order number because the database connection and the network transmission are not involved.
In order to obtain a better-performance order number, a machine code, a time stamp, a serial number and a security code are generated according to the bit number of the self-increment ID, and the method can be implemented according to the following steps:
(1) the destination IP address or machine ID is taken as the machine code.
In the embodiment of the present invention, for example, if the bit number of the machine code is set to 8 bits, 0 to 255 different machine codes can be represented. The fourth segment of the IP address may be used as a machine code. If the cluster nodes IP are not in the same network segment, the machine ID can be used as the machine code.
(2) And determining the number of milliseconds between the current time and the target time, and generating a timestamp according to the obtained number of milliseconds.
In the embodiment of the present invention, the target time may be set to be 0 th day, and the timestamp is the number of milliseconds from the 0 th day of the current time, that is, the maximum 86400000 milliseconds, and a plurality of timestamps less than or equal to 86400000 millimeters may be represented by 27 bits.
(3) And generating a plurality of serial numbers corresponding to the time stamps according to the serial number bit number.
In the embodiment of the present invention, if it is determined that the sequence number bit number is 5 bits, the 5-bit sequence number supports a maximum of 32 order numbers for the same millisecond, and if it exceeds 32, the time stamp is regenerated. Specifically, the number of bits of the serial number is determined according to actual requirements, and the embodiment of the present invention is not limited specifically.
(4) A security code is generated for each serial number based on the number of bits of the security code.
In the embodiment of the invention, a security code is generated for each order number, and the security codes of different orders are discontinuous, so that the discontinuity of the order numbers is ensured. The number of bits of the security code is specifically used, and the embodiment of the present invention is not particularly limited.
In order to improve the security of the order number, a security code is generated for each serial number according to the bit number of the security code, and the method can be implemented according to the following steps:
determining the encryption bit number in the bit number of the security code; and generating the security code according to the bit number of the security code and the encryption bit number.
In the embodiment of the invention, the operation of signing can be realized through the security code, the time stamp, the machine code and the serial number are signed, the falsification, the manual generation and the like are prevented, and the security is improved. One or more bits in the bit number of the security code can be determined as the encryption bit number, the position of the encryption bit number is determined, and a specific code is generated for the position of the secret bit number, so that the security of the security code is higher.
