 struct定义的属性如果是小写开头的,那么该属性不是public的,不能跨包调用 (implicit assignment of unexported field)

type Rect struct {
    x, y float64
    width, height float64
}

// 定义一个对象,以下四种等价。
rect1 := new(Rect)
rect2 := &Rect{}
rect3 := &Rect{0, 0, 100, 200}
rect4 := &Rect{100, height:200}
   
//===================================

package entities

type Company struct {
    Id string
    Name string
    Phone string
    Address string
}


// 声明一个类型
r := entities.Company{Id:"001", Name:"test name", Phone:"test phone", Address:"test address"}
