The MyBatis plus configuration primary key generation strategy is 2, which is to generate IDs using the Twitter snowflake algorithmThe spring boot is configured as:Globalconfiguration conf = new Globalconfiguration (new Logicsqlinjector ());Conf.setidtype (5);This generates a long type, and if you want to convert the ID to a string type, configure the primary key generation strategy to 5.https://gitee.com/baomidou/mybatis-plus/blob/dev/mybatis-plus-su

The recent project used the snowflake algorithm to generate ID, and in the actual running environment will generate duplicate ID, so wrote a go program to verify, by the way also practice the go to the process and channel.As for the process of go and the basic knowledge of the channel, please own Baidu.The code is as follows:Package Mainimport ("FMT" "Github.com/zheng-ji/gosnowflake") func main () {FMT.

First we get the original image into the camera Raw, first we see the data straight square, the upper right corner, there is a white triangle description of the picture, but is white to show the color of the explosion, If it is the other color descr

The IDs generated by Snowflake are divided into four parts:1. First placeConsumes 1bit, and its value is always 0, with no practical effect.2. Time stampTakes up to 41bit, accurate to milliseconds, and can hold a total of approximately 69 years.3. Work Machine IDOccupy 10bit, where high 5bit is the data center ID (datacenterid), low 5bit is the work Node ID (workerid), long can accommodate 1024 nodes.4. Serial numberOccupies 12bit, this value is accum

. Implementing this method requires implementing the Nscoding protocol, which is already implemented by default because of the UIView created.You can go to the head file to view:TimerThe first one:[Nstimer scheduledtimerwithtimeinterval:0.1 target:self selector: @selector (updateimage) Userinfo:nil Repeats:YES];Description: Nstimer is generally used to periodically update some non-interface data, telling how long to call onceThe second one: CADisplayLink *display= [CADisplayLink displayLinkWi

This is a creation in Article, where the information may have evolved or changed. The snowflake algorithm is particularly efficient when generating IDs, and can be consulted: https://segmentfault.com/a/1190000011282426 it guarantees: * All generated IDs are incremented by time trend * Duplicate IDs are not generated throughout the distributed system (because there are datacenterid and Workerid) but in the shadow of a datacenterid, workerid do not nee

Comments: The canvas label and three. js of HTML5 are used to achieve the 3D snowflake flying effect. You can drag the mouse to rotate it. You need to browse it in a browser that supports the CSS3 attribute. The Code is as follows:Var SCREEN_WIDTH = window. innerWidth;Var SCREEN_HEIGHT = window. innerHeight; Var scene;Var renderer; Var mouseY = 0; Var empty whalfy = window. innerHeight/2; Var participant = [];Var participant Image = new Image (); // T
