对应的切片实现sort的这3个接口Len, Less, Swap.就好了.
import "sort"
type user struct {
id int
name string
}
type users []user
func (u users) Len() int {
return len(u)
}
func (u users) Less(i, j int) bool {
if u[i].id == u[j].id {
return u[i].name < u[j].name
}
return u[i].id < u[j].id//sort by id if id is the same sort by name...
}
func (u users) Swap(i ,j int) {
u[i].id, u[j].id = u[j].id, u[i].id
u[i].name, u[j].name = u[j].name, u[i].name
}
uu := []user{{1,"aa"}, {20,"bb"}, {3, "cc"}, {3, "cb"}}
fmt.Println(uu)
sort.Sort(users(uu))
fmt.Println(uu)
