所以弄了个模板式的东西,碰到这类需求,直接把相关函数和参数,丢到run函数去就不用管了,省得浪费时间。
先上个调用例子:
//函数执行模板 //author: Xiong Chuan Liang //date: 2015-3-19 package main import ( "fmt" "log" "os" "utils" ) func main() { log.SetOutput(os.Stdout) w := utils.NewWorker() w.Run("myPrintf()",myPrintf,"aa","bb") } func myPrintf(args ...interface{}) (int,error) { fmt.Println("myPrintf() begin.") for _,arg := range args { fmt.Println("args:",arg) } fmt.Println("myPrintf() end.") panic("尝试抛出panic错误") return 0,nil } /* 运行结果: 2015/03/19 13:49:30 [worker.Run()] 函数: myPrintf() myPrintf() begin. args: aa args: bb myPrintf() end. 2015/03/19 13:49:30 [worker.Run()] panic: myPrintf() 尝试抛出panic错误 2015/03/19 13:49:30 [worker.Run()] 函数:myPrintf() 耗时:0.004000 秒 */调用还是很方便的,传入函数和附带的参数即可.
实现也很简单:
//函数执行模板 //author: Xiong Chuan Liang //date: 2015-3-19 package utils import ( "fmt" "log" "time" ) type workerFunc func(...interface{}) (int,error) type worker struct { } func NewWorker() *worker { return &worker{} } func (w *worker) Run(name string,workerFunc workerFunc,args ...interface{}) (int,error) { now := time.Now() log.Println("[worker.Run()] 函数:",name) defer func() { if r := recover(); r != nil { log.Println("[worker.Run()] panic:\n",name,"\n",fmt.Sprint(r)) w.elasped(name,now,time.Now()) } }() ret,err := workerFunc(args...) w.elasped(name,time.Now()) return ret,err } func (w *worker) elasped(name string,beginTime,endTime time.Time) { log.Printf("[worker.Run()] 函数:%s 耗时:%f 秒 \n",endTime.Sub(beginTime).Seconds()) }
没多少东西，我也就处理func(...interface{}) (int,error)这类函数，其它没管了。
