some useful tool and convertor and etc.
structAutoGenerate structEngin varBindValue
根据struct, 自动生成对应字段的Set()和Get()方法, 同时会为这些方法生成对应的接口
package main
import (
"github.com/gohouse/gocar/structAutoGenerate"
"fmt"
)
type Users struct {
Uid int `gorose:"uid"`
Name string `gorose:"name"`
Age int `gorose:"age"`
}
func main() {
//var a tt
err := structAutoGenerate.New(&structAutoGenerate.Option{
// 要生成的机构体对象
Obj: Users{},
// 生成文件包名
PackageName: "user",
// 指定生成文件保存目录
SavePath: "./users.go",
}).Generate()
fmt.Println(err)
}生成
package user
type IUsers interface {
SetUid(arg int)
GetUid() int
SetName(arg string)
GetName() string
SetAge(arg int)
GetAge() int
}
type Users struct {
Uid int `gorose:"uid"`
Name string `gorose:"name"`
Age int `gorose:"age"`
}
func NewUsers() *Users {
return new(Users)
}
func (o *Users) SetUid(arg int) {
o.Uid = arg
}
func (o *Users) GetUid() int {
return o.Uid
}
func (o *Users) SetName(arg string) {
o.Name = arg
}
func (o *Users) GetName() string {
return o.Name
}
func (o *Users) SetAge(arg int) {
o.Age = arg
}
func (o *Users) GetAge() int {
return o.Age
}结构体操作工具包, 目前提供两个工具
- 抽取结构体的字段指针, 放入一个
[]interface{}中, 同时支持嵌套结构体的循环抽取, 至于抽取出来做什么, 比如可以给他赋值, 在数据库结果集绑定的时候, 很有用 - 获取结构体的内容到一个
[]map[string]inteface{}中, 使用场景: 数据库插入或修改时, 传入结构体数据的解析 - 示例
package structEngin

type Nested2 struct {

}
type Nested3 struct {

}
type Nested struct {

Nested2
Nested3
F4 string
}
func main() {
testGetStructFields()
testStructContent2Map()
}
func testGetStructFields() {
e := structEngin.New()
var n = new(Nested)
res := e.GetStructFields(n)
fmt.Println(res)
// 绑定值
for _, item := range res {
err := varBindValue.BindVal(item, 333)
fmt.Print(err)
}
fmt.Println()
fmt.Println(n)
}
func testStructContent2Map() {
e := structEngin.New()
var n = new(Nested)
n.F1 = 1
n.F2 = 2
n.F3 = 3
n.F4 = "d"
var n2 = Nested{F1: 11, F4: "b"}
var m = []Nested{n2, *n}
res := e.StructContent2Map(m)
fmt.Println(res)
}结果
