golang日期转字符串，仿照C#中的日期格式结构体

1、日期格式集合、日期转字符串方法

package util

import (
	"strings"
	"time"
)
//日期格式：模仿java中的结构体
type DateStyle string

const (
	MM_DD                           = "MM-dd"
	YYYYMM                          = "yyyyMM"
	YYYY_MM                         = "yyyy-MM"
	YYYY_MM_DD                      = "yyyy-MM-dd"
	YYYYMMDD                        = "yyyyMMdd"
	YYYYMMDDHHMMSS                  = "yyyyMMddHHmmss"
	YYYYMMDDHHMM                    = "yyyyMMddHHmm"
	YYYYMMDDHH                      = "yyyyMMddHH"
	YYMMDDHHMM                      = "yyMMddHHmm"
	MM_DD_HH_MM                     = "MM-dd HH:mm"
	MM_DD_HH_MM_SS                  = "MM-dd HH:mm:ss"
	YYYY_MM_DD_HH_MM                = "yyyy-MM-dd HH:mm"
	YYYY_MM_DD_HH_MM_SS             = "yyyy-MM-dd HH:mm:ss"
	YYYY_MM_DD_HH_MM_SS_SSS         = "yyyy-MM-dd HH:mm:ss.SSS"

	MM_DD_EN                        = "MM/dd"
	YYYY_MM_EN                      = "yyyy/MM"
	YYYY_MM_DD_EN                   = "yyyy/MM/dd"
	MM_DD_HH_MM_EN                  = "MM/dd HH:mm"
	MM_DD_HH_MM_SS_EN               = "MM/dd HH:mm:ss"
	YYYY_MM_DD_HH_MM_EN             = "yyyy/MM/dd HH:mm"
	YYYY_MM_DD_HH_MM_SS_EN          = "yyyy/MM/dd HH:mm:ss"
	YYYY_MM_DD_HH_MM_SS_SSS_EN      = "yyyy/MM/dd HH:mm:ss.SSS"

	MM_DD_CN                        = "MM月dd日"
	YYYY_MM_CN                      = "yyyy年MM月"
	YYYY_MM_DD_CN                   = "yyyy年MM月dd日"
	MM_DD_HH_MM_CN                  = "MM月dd日 HH:mm"
	MM_DD_HH_MM_SS_CN               = "MM月dd日 HH:mm:ss"
	YYYY_MM_DD_HH_MM_CN             = "yyyy年MM月dd日 HH:mm"
	YYYY_MM_DD_HH_MM_SS_CN          = "yyyy年MM月dd日 HH:mm:ss"

	HH_MM                           = "HH:mm"
	HH_MM_SS                        = "HH:mm:ss"
	HH_MM_SS_MS                     = "HH:mm:ss.SSS"
)

//日期转字符串
func FormatDate(date time.Time, dateStyle DateStyle) string {
	layout := string(dateStyle)
	layout = strings.Replace(layout, "yyyy", "2006", 1)
	layout = strings.Replace(layout, "yy", "06", 1)
	layout = strings.Replace(layout, "MM", "01", 1)
	layout = strings.Replace(layout, "dd", "02", 1)
	layout = strings.Replace(layout, "HH", "15", 1)
	layout = strings.Replace(layout, "mm", "04", 1)
	layout = strings.Replace(layout, "ss", "05", 1)
	layout = strings.Replace(layout, "SSS", "000", -1)

	return date.Format(layout)
}

　　2、测试代码

package main

import (
    "fmt"
    "time"
    "util"
)

func main() {
	fmt.Println(util.FormatDate(time.Now(), util.HH_MM))
	fmt.Println(util.FormatDate(time.Now(), util.HH_MM_SS))
	fmt.Println(util.FormatDate(time.Now(), util.HH_MM_SS_MS))

	fmt.Println(util.FormatDate(time.Now(), util.MM_DD_HH_MM_SS_EN))
	fmt.Println(util.FormatDate(time.Now(), util.YYMMDDHHMM))
	fmt.Println(util.FormatDate(time.Now(), util.YYYYMM))
	fmt.Println(util.FormatDate(time.Now(), util.YYYYMMDD))
	fmt.Println(util.FormatDate(time.Now(), util.YYYYMMDDHH))
	fmt.Println(util.FormatDate(time.Now(), util.YYYYMMDDHHMM))
	fmt.Println(util.FormatDate(time.Now(), util.YYYYMMDDHHMMSS))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_CN))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_DD))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_DD_CN))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_DD_EN))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_DD_HH_MM))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_DD_HH_MM_CN))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_DD_HH_MM_EN))

	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_DD_HH_MM_SS_SSS_EN))
	fmt.Println(util.FormatDate(time.Now(), util.YYYY_MM_EN))

	fmt.Println(util.FormatDate(time.Now(), "yyyy/MM/dd HH:mm:ss.SSSSSSSSS"))
	fmt.Println(util.FormatDate(time.Now(), "2006 01 02 15:04:05.00000000"))
