### 问题 ### 问题
+ 手动管理: main, 自己组装对象, 业务越复杂，组装难度越高
![](./docs/oop.png)
+ ioc: 引入了一个中间层, 这个中间层负责对象的管理, 自己对象自己去ioc获取依赖，而不是我们开发者 把依赖传递给他，完成 对象的 依赖 由被动 变成主动, ioc, 依赖倒置
![](./docs/ioc.png)
### 基于mcube ioc来改造
![alt text](image.png)
https://www.mcube.top/docs/framework/
1. 对象注册到ioc: 把我们的对象实现了1个IOC对象(符合Ioc接口定义的对象), 可以通过继承基础类，直接实现接口ObjectImpl
+ 2 APIHandler: TokenApiHandler, BlogApiHandler
+ 3 Controller: UserServiceImpl, TokenServiceImpl, BlogServiceImpl
对象注册
```go
func init() {
ioc.Controller().Registry(&TokenServiceImpl{})
}
// 定义一个struct, 用于实现 UserService就是刚才定义的接口
// 怎么才能判断这个结构体没有实现这个接口
type TokenServiceImpl struct {
ioc.ObjectImpl
// user service
user user.AdminService
}
func (*TokenServiceImpl) Name() string {
return token.AppName
}
// 他需要自己去获取依赖，通过ioc
func (i *TokenServiceImpl) Init() error {
i.user = user.GetService()
return nil
}
```
对象获取
```go
func GetService() Service {
return ioc.Controller().Get(AppName).(Service)
}
```
