structA 和 structB 如何判断是否相等

需要用到 反射 reflect.DeepEqual() 进行对比

package main
import (
 "fmt"
 "reflect"
)

type A struct {
    s string
}

func main() {
    //结构体
     a1 := A{s: "abc"}
     a2 := A{s: "abc"}
     if reflect.DeepEqual(a1, a2) {
          fmt.Println(a1, "==", a2)
     }
   //切片
     b1 := []int{1, 2}
     b2 := []int{1, 2}
     if reflect.DeepEqual(b1, b2) {
          fmt.Println(b1, "==", b2)
     }
     //map
     c1 := map[string]int{"a": 1, "b": 2}
     c2 := map[string]int{"a": 1, "b": 2}
     if reflect.DeepEqual(c1, c2) {
        fmt.Println(c1, "==", c2)
     }
}

执行结果

{abc} == {abc}
[1 2] == [1 2]
map[a:1 b:2] == map[a:1 b:2]
