[Golang]嵌套struct转换成json时丢失信息

[cw03192]

code如下：

package aaa

import (
	"encoding/json"
	"fmt"
)

type Person struct {
	ID   string
	Name string
}

type Class struct {
	ID    string
	Name  string
	stuff []Person
}

func Check() {

	pa := Person{ID: "001", Name: "赵大"}
	pb := Person{"002", "刘二"}
	ca := Class{"001", "初一（3）班", []Person{pa, pb}}
	
	fmt.Println(ca)

	data, _ := json.MarshalIndent(ca, "", "    ")

	fmt.Printf("%s\n", data)

}

运行结果（Person对象信息没了）：
{001 初一（3）班 [{001 赵大} {002 刘二}]}
{
"ID": "001",
"Name": "初一（3）班"
}

没导出 struct里stuff []Person要大写开头
