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.
The embodiment of the invention discloses a serial number generation method, which is shown in figure 1 and comprises the following steps:
101. in the starting process of the target application, a numbering request is sent to an application numbering server, so that the application numbering server queries a machine number in a numbering database according to the numbering request.
Wherein, the serial number database stores a T _ APP _ INFO table, and the table stores n machine numbers. And inquiring the corresponding machine number in the number database according to the application name. If the machine number cannot be inquired, setting the current machine number segment in the number database to be 1-n, and setting the machine number corresponding to the target application to be 1.
If the largest machine number segment in the current number database is found to be larger than the set threshold, for example, the threshold is set to 16383, it means that the machine number needs to be numbered from 1 again.
In actual use, generally, a plurality of nodes are arranged for each application, and each node generates a serial number correspondingly. For example, one application has 10 nodes, and when a machine number is acquired for the first time, the machine number acquired in the number database is 1-10; and when the machine number is acquired for the second time, the machine numbers 11-20 … … acquired in the number database are analogized until the machine number to be acquired is greater than the set threshold value, and the loop is started from 1 again. Since the node of each application is not larger than the set threshold, the case where the machine number is not sufficient or duplicated does not occur.
Specifically, step 101 includes:
generating a numbering request in the starting process of 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, in the application starting process, the numbering request may be generated by a distributed serial number component in the application.
There are many specific protocol links, such as hypertext transfer http protocol, user datagram UDP protocol, and so on.
102. And receiving the machine number returned by the application number server.
In the embodiment, the machine number is acquired in the starting process of the target application, and then the machine number is not interacted with an application number server and other external servers, so that the performance is improved, and the 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 sequence number. The sign bit, version number, time stamp, clock callback identification, serial number and machine number 6 information are stored with binary 64 bits.
1) The position of the sign bit in the binary digit is bit 64, 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 32-34 bits, and the value range is 1-999;
4) the machine number is located 17 th to 31 th bits in the binary digit, and the value is the value obtained in step 102.
5) The positions of the clock callback identifications in the binary digits are 15 th and 16 th bits. This identification bit is incremented by 1 when the current timestamp is found to be less than the previously acquired timestamp.
6) The position of the sequence 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 sequence number is generated by increasing by 1 each time, and if the sequence number is 16383, the sequence number is delayed until the timestamp is acquired again to generate the sequence number in the next second.
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 starting process of the target application, the server inquires the machine number by requesting the application number, and after the machine number is inquired, the server is not accessed any more, but the serial number is generated by the server, so that the serial number can be generated quickly, efficiently and accurately.
The embodiment of the invention discloses a serial number generation method, which is shown in figure 2 and comprises the following steps 201-208:
201. and in the starting process of the target application, sending a numbering request to an application numbering server.
Specifically, step 201 includes: in the starting process of 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. And the distributed serial number component sends the numbering request to an application numbering server in a hypertext transfer protocol http mode.
202. And after receiving the numbering request, the application numbering server acquires 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 main key according to the network address.
In this embodiment, after receiving the numbering request, the application numbering server automatically obtains the IP address of the requester. And the application name is used as a main key, and distributed locking is performed by utilizing the setnx command characteristic of Redis to ensure the concurrence problem of machine number distribution.
To prevent the processes of multiple applications in a distributed system from interfering with each other, a distributed coordination technique is needed to schedule the processes of the applications. The core of the distributed coordination technology is realized by distributed locks.
204. The application number 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 machine number in the numbering database 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 number server judges whether to inquire the current maximum machine number in a number database according to the application name in the number request, if not, the step 302 is executed; if yes, go to step 303.
Wherein, the serial number database comprises n machine serial 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 executed.
303. If the current maximum machine number is obtained through inquiry, whether the current maximum machine number is larger than or equal to a first threshold value is judged, if yes, step 304 is executed, and if not, step 305 is executed.
304. The current machine number segments are 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 from small to large, and updating the n machine numbers to the next adjacent number section after the current machine number section is used.
Taking n as 10 as an example, the first number segment is 1-10, the next adjacent number segment is 11-20, … … and so on. When the maximum number of the n machine numbers exceeds the first threshold, it means that the machine number should restart counting.
The first threshold value may be set according to actual requirements, for example, 16383.
During specific setting, the number of nodes in one application is less than or equal to n, and the first threshold value should not exceed the number of nodes in one application, so that when the serial number of the applied node is updated, the situation that the machine number required for updating after each restart exceeds the first threshold value does not occur.
206. The application number server retries requesting the distributed lock for the interval period and performs step 204.
207. And the target application receives the machine number returned by the application number server.
The target application is provided with a distributed serial number component, and the function of receiving the machine serial number and generating the serial number in the subsequent steps can be realized through the component.
208. The target application generates a sign bit, a version number, a timestamp, 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 according to the sign bit, the version number, the timestamp, the clock callback identifier, the serial number and a machine number of the target application through the distributed serial number component.
Wherein, the clock callback identifier is generated through the following steps S281 to S283:
s281, acquiring a timestamp, and judging whether the currently acquired timestamp is larger than a previous timestamp;
s282, if yes, acquiring a clock callback identification bit;
and S283, if not, increasing the clock callback identification bit by 1 to obtain the clock callback identification bit.
Through the generation of the clock callback identification bit, the uniqueness of the serial number can be guaranteed under the severe condition that the machine clock generates callback.
Referring to fig. 4, the serial number is generated through the following steps 401 to 406:
401. and judging whether the current time stamp and the previous time stamp are in the same second, if not, executing the step 402, and if so, executing the step 403.
402. And setting the sequence number to be 0, and marking after the timestamp is acquired again in the next second.
It should be explained that for the case that the time stamps are not in the same second, the two sequence numbers should belong to different serial number sequences. Through the processing of step 402, sequence 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. And if the sequence number after the self increment of 1 is larger than a second threshold value, setting the sequence number to be 0, and marking after waiting for reacquiring the timestamp in the next second.
Wherein the second threshold may be 16383.
406. And if the sequence number after the self increment of 1 is less than or equal to a second threshold value, outputting the sequence number.
In the serial number generation method provided by this embodiment, in the process of starting the target application, the application number server is requested to query the machine number, and after the machine number is queried, the server is not accessed any more, but the serial number is generated by the server, so that the serial number can be generated quickly, efficiently and accurately.
In addition, in the severe condition of clock dial-back, the serial number generation method generates the clock dial-back identification bit through the timestamp, and increases the clock dial-back identification bit by 1 when the current acquired timestamp is smaller than the previous timestamp, so that the uniqueness of the generated serial number can be ensured even when the clock dial-back occurs.
