<p>请解释Go语言中的依赖注入实现方式，并给出示例代码。</p> <pre><code class="language-go">package main import "fmt" type Service interface { Perform() } type MyService struct{} func (s MyService) Perform() { fmt.Println("Performing service") } type Controller struct { service Service } func NewController(s Service) *Controller { return &Controller{service: s} } func (c *Controller) Execute() { c.service.Perform() } func main() { service := MyService{} controller := NewController(service) controller.Execute() }</code></pre><br><p>在Go语言中，依赖注入可以通过构造函数注入实现。依赖注入有助于解耦组件，提高代码的可测试性和维护性。常见场景包括控制器依赖服务、服务依赖存储等。</p>
