适配器模式

被适配目标接口

package adapter

type source  interface {
    SpecificRequest() string
}

被适配的目标

package adapter

type sourceImpl struct {}

func NewSourceImpl() source {
    return &sourceImpl{}
}

func (a *sourceImpl)SpecificRequest() string {
    return "adapter message"
}

适配的目标接口

package adapter

type target interface {
    Request() string
}

适配的目标

package adapter

type targetImpl struct {
    source
}

func NewTargetImpl(a source) target {
    return &targetImpl{source:a}
}

func (t *targetImpl)Request() string {
    return t.source.SpecificRequest()
}

使用者

package adapter

type User struct{
    tg target
}

func NewUser(tg target) *User {
    return &User{tg:tg}
}

func (u *User)getResult() {
    fmt.Println(u.tg.Request())
}

测试文件

package adapter

func TestAdapter(t *testing.T) {
    a := NewSourceImpl()
    tg := NewTargetImpl(a)
    u := NewUser(tg)
    u.getResult()
}
