遇到一个关于map struct，很奇怪的问题，求大牛指教，谢谢了

如题，先上代码 package main import ( "fmt" "io/ioutil" "strings" ) var ( row1 = [][]string{ {"Q-843A磷化", "2016", "2015年结转", "0", "60"}, {"Q-843A磷化", "2016", "01月_结存", "0", "60"}, {"Q-843A磷化", "2016", "02月_结存", "0", "60"}, {"Q-843A磷化", "2016", "03月_结存", "0", "60"}, {"Q-843A磷化", "2016", "04月_结存", "0", "60"}, {"Q-843A磷化", "2016", "05月_结存", "0", "60"}, {"Q-843A磷化", "2016", "06月_结存", "0", "60"}, {"Q-843A磷化", "2016", "07月_结存", "0", "60"}, {"Q-843A磷化", "2016", "08月_结存", "0", "60"}, {"Q-843A磷化", "2016", "09月_结存", "0", "0"}, {"Q-843A磷化", "2016", "09月_生产", "0", "0"}, {"Q-843A磷化", "2016", "10月_结存", "0", "0"}, {"Q-843A磷化", "2016", "11月_结存", "0", "0"}, {"Q-843A磷化", "2016", "12月_结存", "0", "0"}, {"Q-843A磷化", "2017", "2016年结转", "0", "0"}, {"Q-843A磷化", "2017", "01月_结存", "0", "0"}, {"Q-843A磷化", "2017", "02月_结存", "0", "0"}, {"Q-843A磷化", "2017", "03月_", "-13", "0"}, {"Q-843A磷化", "2017", "03月_20161109-19", "109", "0"}, {"Q-843A磷化", "2017", "03月_20161109-19", "23", "0"}, {"Q-843A磷化", "2017", "03月_结存", "0", "119"}, {"Q-843A磷化", "2017", "04月_结存", "0", "119"}, {"Q-843A磷化", "2017", "05月_结存", "0", "119"}, {"Q-843A磷化", "2017", "06月_结存", "0", "119"}, {"Q-843A磷化", "2017", "07月_结存", "0", "119"}, {"Q-843A磷化", "2017", "08月_结存", "0", "119"}, {"Q-843A磷化", "2017", "09月_结存", "0", "119"}, {"Q-843A磷化", "2017", "10月_结存", "0", "119"}, {"Q-843A磷化", "2017", "11月_结存", "0", "119"}, {"Q-843A磷化 ", "2017", "12月", "27", "0"}, {"Q-843A磷化", "2017", "12月_结存", "27", "146"}, {"Q-843A磷化", "2018", "2017年结转", "0", "146"}, {"Q-843A磷化", "2018", "01月_结存", "0", "146"}, {"Q-843A磷化", "2018", "02月_结存", "0", "146"}, {"Q-843A磷化", "2018", "03月_结存", "0", "146"}} ) type huopin struct { name string jiezhuan15 []string jiezhuan16 []string jiezhuan17 []string isruku16 bool isruku17 bool isruku18 bool jiecun16 [][]string jiecun17 [][]string jiecun18 [][]string } func MyJiangXu(src [][]string, n int) { if len(src) == 1 { return } for i := 0; i < len(src)-1; i++ { for j := i + 1; j < len(src); j++ { if src[i][n] < src[j][n] { src[i], src[j] = src[j], src[i] } } } } func main() { var huopinMap = make(map[string]*huopin) data, err := ioutil.ReadFile("F:\\workspace\\src\\mygo\\myApp1\\test1") if err != nil { fmt.Println("readfile err: ", err, data) } // for _, line := range strings.Split(string(data), "\n") { // row := strings.Split(line, "\t") for _, line := range row1 { row := line if len(row) < 2 { fmt.Println(row) continue } _, ok := huopinMap[row[0]] if !ok { huopinMap[row[0]] = new(huopin) huopinMap[row[0]].name = row[0] } if strings.Contains(row[2], "2015年结转") { huopinMap[row[0]].jiezhuan15 = row } if strings.Contains(row[2], "2016年结转") { huopinMap[row[0]].jiezhuan16 = row } if strings.Contains(row[2], "2017年结转") { huopinMap[row[0]].jiezhuan17 = row } if strings.Contains(row[2], "月_结存") { if strings.Contains(row[1], "2016") { huopinMap[row[0]].jiecun16 = append(huopinMap[row[0]].jiecun16, row) } if strings.Contains(row[1], "2017") { huopinMap[row[0]].jiecun17 = append(huopinMap[row[0]].jiecun17, row) } if strings.Contains(row[1], "2018") { huopinMap[row[0]].jiecun18 = append(huopinMap[row[0]].jiecun18, row) } } if strings.Compare(row[3], "0") != 0 { if strings.Contains(row[1], "2016") { huopinMap[row[0]].isruku16 = true } if strings.Contains(row[1], "2017") { huopinMap[row[0]].isruku17 = true } if strings.Contains(row[1], "2018") { huopinMap[row[0]].isruku18 = true } } } fmt.Println(len(huopinMap)) for k, v := range huopinMap { fmt.Println(k) fmt.Println(&v) if len(v.jiecun16) < 1 && len(v.jiecun17) < 1 && len(v.jiecun18) < 1 { fmt.Println("len 16", len(v.jiecun16)) fmt.Println("len 17", len(v.jiecun17)) fmt.Println("len 18", len(v.jiecun18)) } if len(v.jiecun16) > 0 { MyJiangXu(v.jiecun16, 2) } if len(v.jiecun17) > 0 { MyJiangXu(v.jiecun17, 2) } if len(v.jiecun18) > 0 { MyJiangXu(v.jiecun18, 2) } fmt.Println("排序后：", v) } } 如题，输出信息，如下 2 Q-843A磷化 0xc042004038 排序后： &{Q-843A磷化 [Q-843A磷化 2016 2015年结转 0 60] [Q-843A磷化 2017 2016年结转 0 0] [Q-843A磷化 2018 2017年结转 0 146] false true false [[Q-843A磷化 2016 12月_结存 0 0] [Q-843A磷化 2016 11月_结存 0 0] [Q-843A磷化 2016 10月_结存 0 0] [Q-843A磷化 2016 09月_结存 0 0] [Q-843A磷化 2016 08月_结存 0 60] [Q-843A磷化 2016 07月_结存 0 60] [Q-843A磷化 2016 06月_结存 0 60] [Q-843A磷化 2016 05月_结存 0 60] [Q-843A磷化 2016 04月_结存 0 60] [Q-843A磷化 2016 03月_结存 0 60] [Q-843A磷化 2016 02月_结存 0 60] [Q-843A磷化 2016 01月_结存 0 60]] [[Q-843A磷化 2017 12月_结存 27 146] [Q-843A磷化 2017 11月_结存 0 119] [Q-843A磷化 2017 10月_结存 0 119] [Q-843A磷化 2017 09月_结存 0 119] [Q-843A磷化 2017 08月_结存 0 119] [Q-843A磷化 2017 07月_结存 0 119] [Q-843A磷化 2017 06月_结存 0 119] [Q-843A磷化 2017 05月_结存 0 119] [Q-843A磷化 2017 04月_结存 0 119] [Q-843A磷化 2017 03月_结存 0 119] [Q-843A磷化 2017 02月_结存 0 0] [Q-843A磷化 2017 01月_结存 0 0]] [[Q-843A磷化 2018 03月_结存 0 146] [Q-843A磷化 2018 02月_结存 0 146] [Q-843A磷化 2018 01月_结存 0 146]]} Q-843A磷化 0xc042004038 len 16 0 len 17 0 len 18 0 排序后： &{Q-843A磷化 [] [] [] false true false [] [] []} 为什么这个huopinMap[Q-843A磷化] 这个会有2个？并且地址还相同，里面内容 string bool 类型的值也相同，但是切片 类型的一个有值，一个确实空。 按说这个huopinMap[Q-843A磷化] 不是应该就一个吗？为啥会出现2的？？？？ 求解，谢谢
