Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention discloses a serial number generation method, which comprises the following steps of:
101. and in the process of starting the target application, sending a numbering request to an application numbering server so that the application numbering server queries the machine number in a numbering database according to the numbering request.
Wherein, the number database stores a T_APP_INFO table, and the table stores n machine numbers. And according to the application name, inquiring the corresponding machine number in a number database. If the machine number is not found, the current machine number section in the number database is set to 1-n, and the machine number corresponding to the target application is set to 1.
If the largest machine number segment in the current number database is found to be greater than the set threshold, for example, the threshold is set to 16383, the machine number needs to be numbered again from 1.
In actual use, typically, each application arranges a plurality of nodes, each of which generates a serial number accordingly. For example, an application has 10 nodes, and when the machine number is acquired for the first time, the machine number acquired in the number database is 1-10; in the second acquisition of the machine number, the machine numbers obtained in the number database are 11-20 … …, and so on, until the machine number to be obtained is greater than the set threshold, the cycle is restarted from 1. Since the node of each application is not greater than the set threshold, there is no situation where the machine number is not used enough or is repeated.
Specifically, step 101 includes:
generating a numbering request in the process of starting a target application, wherein the numbering request comprises an application name, a host name and a local area network address; and sending the numbering request to the application numbering server in a protocol link mode.
In this embodiment, during the application starting process, the serial number request may be generated by the distributed serial number component in the application.
There are various specific protocol links, such as hypertext transfer http protocol, user datagram UDP protocol, etc.
102. And receiving the machine number returned by the application number server.
In this embodiment, the machine number is acquired during the starting process of the target application, and then interaction with an external server such as an application number server is no longer performed, so that performance is improved, and dependence is reduced.
103. And generating serial number information of the target application, and generating a serial number corresponding to the target application according to the serial number information and the machine number.
Wherein, the serial number information includes: at least one of a sign bit, a version number, a timestamp, a clock callback identification, and a serial number. The binary 64 bits are used to store the 6 information of sign bit, version number, timestamp, clock callback identification, serial number and machine number.
1) The position of the sign bit in the binary digit is the 64 th bit, and the default value is 0;
2) The position of the second-level timestamp in the binary digits is 35 bits to 63 bits, and the value is the acquired current system timestamp;
3) The position of the version number in the binary digits is 32 to 34 bits, and the value range is 1 to 999;
4) The machine number is located from bit 17 to bit 31 in the binary digit and the value is the value obtained in step 102.
5) The positions of the clock callback identification in the binary digits are the 15 th and 16 th bits. When the current timestamp is found to be smaller than the previously acquired timestamp, this identification bit is incremented by 1.
6) The position of the serial number in the binary digit is 1 to 14 bits. The value range is 0 to 16383, the initial value is 0 in the current second, the serial number is automatically increased by 1 each time, and if the serial number is equal to 16383, the serial number is delayed until the next second to reacquire the time stamp to generate the serial number.
Referring to Table 1 below, table 1 shows a structural representation of a serial number.
TABLE 1
According to the serial number generation method provided by the embodiment of the invention, in the process of starting the target application, the machine number is queried through the request application number server, and after the machine number is queried, the server is not accessed any more, and the serial number is generated by the request application number server, so that the serial number can be generated rapidly, efficiently and accurately.
The embodiment of the invention discloses a serial number generation method, which is shown in fig. 2 and comprises the following steps 201 to 208:
201. and in the process of starting the target application, sending a numbering request to an application numbering server.
Specifically, step 201 includes: in the process of starting the target application, a numbering request is generated through a distributed serial number component, wherein the numbering request comprises an application name, a host name and a local area network address. The distributed serial number component sends the numbering request to the application numbering server in the manner of hypertext transfer protocol (http).
202. After receiving the numbering request, the application numbering server obtains the network address for sending the numbering request.
203. And the application numbering server requests the distributed lock by taking the application name as a primary key according to the network address.
In this embodiment, the application numbering server automatically obtains the IP address of the requester after receiving the numbering request. And the application name is used as a primary key, and the distributed lock is performed by utilizing the setnx command characteristic of Redis so as to ensure that the machine number is distributed and the problem is solved.
In order to prevent interference between processes of multiple applications in a distributed system, a distributed coordination technique is required to schedule the processes of the applications. The core of the distributed coordination technology is realized through distributed locks.
204. The application numbering server determines whether a distributed lock is acquired, if so, step 205 is executed, and if not, step 206 is executed.
205. The application numbering server queries the numbering database for machine numbers according to the numbering request and then performs step 207.
Specifically, referring to FIG. 3, step 205 includes the following steps 301-305:
301. the application numbering server judges whether to query the current largest machine number in a numbering database according to the application name in the numbering request, and if not, the step 302 is executed; if yes, go to step 303.
Wherein the numbering database comprises n machine numbers.
302. If the current maximum machine number is not found, the current machine number segment is determined to be 1 to n, and then step 305 is performed.
303. If the current maximum machine number is obtained, it is determined whether the current maximum machine number is greater than or equal to the first threshold, if yes, step 304 is executed, and if not, step 305 is executed.
304. The current machine number segment is updated to 1 to n and then step 305 is performed.
305. And sequentially determining the machine numbers corresponding to the number requests in the current machine number section according to the order from small to large, and updating the n machine numbers into the next adjacent number section after the current machine number section is used.
Taking n=10 as an example, the first numbered segment is 1 to 10, the next adjacent numbered segment is 11 to 20, … …, and so on. When the largest number of the n machine numbers exceeds the first threshold, this means that the machine numbers should restart counting.
The first threshold may be set according to actual requirements, for example, 16383.
When the method is specifically set, the number of the nodes in one application is smaller than or equal to n, and the first threshold value should not exceed the number of the nodes in one application, so that the situation that the machine number required for updating after restarting each time exceeds the first threshold value can not occur when the nodes of the application update the serial number.
206. The application numbering server retries requesting the distributed lock for an interval period and performs step 204.
207. And the target application receives the machine number returned by the application number server.
The distributed serial number component is arranged in the target application, and can be used for receiving the machine number and generating the serial number in the subsequent step.
208. And the target application generates a sign bit, a version number, a time stamp, a clock callback identifier and a serial number of the target application through the distributed serial number component, and generates a serial number corresponding to the target application through the distributed serial number component according to the sign bit, the version number, the time stamp, the clock callback identifier, the serial number and the machine number of the target application.
The clock callback identifier is generated by the following steps S281 to S283:
s281, acquiring a time stamp, and judging whether the currently acquired time stamp is larger than the previous time stamp;
s282, if yes, acquiring a clock callback identification bit;
and S283, if not, the clock callback identification bit is automatically increased by 1, and the clock callback identification bit is obtained.
The clock callback identification bit is generated, so that the uniqueness of the serial number can be guaranteed under the severe condition that the machine clock is callback.
Wherein, referring to fig. 4, the serial number is generated by the following steps 401-406:
401. whether the current time stamp is within the same second as the previous time stamp is determined, if not, step 402 is executed, and if yes, step 403 is executed.
402. The serial number is set to 0 and the marking is performed after waiting for the next second to reacquire the timestamp.
It should be explained that for the case that the time stamps are not in the same second, the two serial numbers should belong to different serial numbers. Through the processing of step 402, the serial numbers which do not belong to the same serial number sequence are prevented from being generated in the same serial number sequence, and the accuracy of serial number generation is ensured.
403. The sequence number is incremented by 1.
404. And judging whether the sequence number after the self-increment of 1 is larger than a second threshold value.
405. If the serial number after the self-increment of 1 is larger than the second threshold value, the serial number is set to 0, and the marking is carried out after the next second of re-acquisition of the time stamp is waited.
Wherein the second threshold may be 16383.
406. And if the sequence number after the self-increment of 1 is smaller than or equal to a second threshold value, outputting the sequence number.
According to the serial number generation method, in the process of starting the target application, the application number server is requested to inquire the machine number, and after the machine number is inquired, the server is not accessed any more, the serial number is generated by the server, so that the serial number can be generated rapidly, efficiently and accurately.
In addition, in the method for generating the serial number, the clock callback identification bit is generated through the time stamp, and the clock callback identification bit is automatically increased by 1 under the condition that the currently acquired time stamp is smaller than the previous time stamp, so that the uniqueness of the generated serial number can be ensured even when the clock callback occurs.
