如何使用反射对比三个 Golang 结构体并处理差异？

type person struct {
    name      string
    age       uint8
    married   bool
    hobbies   []string
    education map[string]string
}

package main

import (
    "fmt"
    "reflect"
)

type person struct {
    name      string
    age       uint8
    married   bool
    hobbies   []string
    education map[string]string
}

func main() {
    a := person{
        name:      "john",
        age:       19,
        married:   false,
        hobbies:   []string{"dance", "music"},
        education: map[string]string{"university": "xx school"},
    }

    b := person{
        name:      "jim",
        age:       19,
        married:   false,
        hobbies:   []string{"singing", "music"},
        education: map[string]string{"university": "xx school"}
    }

    c := person{}

    avalue := reflect.valueof(a)
    atype := reflect.typeof(a)

    bvalue := reflect.valueof(b)

    cvalue := reflect.valueof(&c) // 需要使用c的引用，因为后面会给c赋值

    for i := 0; i < avalue.numfield(); i++ {
        afield := avalue.field(i)    // 当前字段的value对象
        afieldtype := atype.field(i) // 当前字段的成员类型，用于获取字段名称afieldtype.name
        bfield := bvalue.field(i)

        fmt.printf("%v: %v - %v\n", afieldtype.name, afield.interface(), bfield.interface())
        fmt.printf("========================\n")

        // 切片和map不能直接比较，需要特殊处理。这里用interface断言判断类型，然后处理。
        switch afield.kind() {
        case reflect.map:
            aedu := afield.interface().(map[string]string)
            bedu := afield.interface().(map[string]string)
            fmt.printf("%+v - %+v\n", aedu, bedu)
        case reflect.slice:
            // ...略
        default:
            // 其他字段，直接赋值给c，否则用b的成员赋值给c
            if afield.interface() != bfield.interface() {
                cvalue.elem().field(i).set(afield)
            } else {
                cvalue.elem().field(i).set(bfield)
            }
        }
    }

    fmt.printf("%+v\n", c)
}
