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. Println ("Hell Go!") IW, err: = Gosnowflake.newi

To give you Photoshop software users to share the details of the fashion of the snowflake effect of the production of a tutorial. Tutorial Sharing: Original: 1. 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

. 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
