该博客探讨了一个使用Go语言实现的生产者消费者模型。通过`zhoulin`函数生成随机数作为产品，`baodelu`函数进行计算求和，利用通道`jobchan`和`resultchan`进行数据传递。此模型展示了并发处理和同步的基本概念。

生产消费者模型

package main

import "fmt"
import "time"
import "sync"
import "math/rand"

type job struct{
	value int64
}

type result struct{
	job *job
	sum int64
}

var jobchan = make(chan *job, 100)
var resultchan = make(chan *result, 100)
var wg sync.WaitGroup

func zhoulin(zl chan <- *job){
	defer wg.Done()
	for {
		x := rand.Int63()
		newjob := &job{
			value :x,
		}
		zl <- newjob
		time.Sleep(time.Microsecond * 500)
	}
}

func baodelu(zl <-chan *job, resultchan chan<- *result){
	defer wg.Done()
	for {
		job := <-zl
		sum := int64(0)
		n := job.value
		for n > 0{
			sum += n % 10
			n = n / 10
		}
		newresult := &result{
			job :job,
			sum :sum,
		}
		resultchan <- newresult
	}
}


func main () {
	
	wg.Add(1)
	go zhoulin(jobchan)
	wg.Add(5)
	for i := 0; i < 5; i++{
		go baodelu(jobchan,resultchan)
	}
	for result := range resultchan{
		fmt.Printf("value:%d,sum:%d",result.job.value,result.sum)
	}
	wg.Wait()
}
