LCLCF

mapping

• 普通的map 映射 结构体
• mysql结构集 映射 结构体

goto mapping

sqltomodel

• 数据表转换成model文件

goto sqltomodel

package main

import (
	"modules/sqltomodel/conf"
	"modules/sqltomodel/dbtools"
)

func main() {
	// 首先初始化struct对象，用于保存配置文件信息
	var confS conf.Config
	// 通过toml.DecodeFile将toml配置文件的内容，解析到struct对象
	err := conf.GetConf("C:/Users/cyz/Desktop/git-project/Zmodules/sqltomodel/conf/mysql_map.toml", &confS)
	if err != nil {
		return
	}
	for _, v := range confS.Database {
		var MasterDbConfig = &dbtools.DbConf{
			Host:   v.Host,
			Port:   v.Port,
			User:   v.User,
			Pwd:    v.Pwd,
			DbName: "service",
		}
		dbtools.Init(MasterDbConfig)             //初始化数据库
		dbtools.Generate("C:/Users/cyz/Desktop/git-project/Zmodules/sqltomodel/models/", "service") //生成指定表信息，可变参数可传入多个表名
	}

}

pprof

• pprof的使用

goto pprof

package main

import (
	"log"
	"net/http"
	_ "net/http/pprof"
)

var dataS []string

func Add(str string) string {
	data := []byte(str)
	sData := string(data)
	dataS = append(dataS, sData)

	return sData
}

func main() {
	go func() {
		for {
			log.Println(Add("https://github.com/EDDYCJY"))
		}
	}()
	_ = http.ListenAndServe("0.0.0.0:6060", nil)
}

signal.Notify

• signal.Notify 的使用

goto signal.Notify

package main

import (
	"fmt"
	"os"
	"os/signal"
	"syscall"
)

func main() {
	fmt.Println(fmt.Sprintf("开始服务！！！"))
	quit := make(chan os.Signal)
	signal.Notify(quit, syscall.SIGKILL, syscall.SIGQUIT, syscall.SIGINT, syscall.SIGTERM)
	<-quit
	fmt.Println(fmt.Sprintf("结束服务！！！"))
}

task

• 计时的任务队列
• 可分为立即执行和定时执行

goto task

package main

import (
	"modules/task/taskFunc"
	"os"
	"os/signal"
	"syscall"
)

func main() {
	// 初始化，从文件中获取中断时间的任务
	taskFunc.Start()
	// 初始化一个计时器
	taskFunc.InitTimer()
	// 随机产生数据
	taskFunc.RandData()
	quit := make(chan os.Signal)
	signal.Notify(quit, syscall.SIGKILL, syscall.SIGQUIT, syscall.SIGINT, syscall.SIGTERM)
	<-quit
	// 中断期间会以json格式保存任务
	taskFunc.Interrupt()
}

gin + pprof

• gin框架结合pprof 的使用

goto gin + pprof

go.mod
