设计模式6——工厂方法模式实践

简单工厂模式  ：要知道参数 
工厂方法模式：要知道工厂方法

package initial2
type Cache interface {
   Set (key string,value string)
   Get(key string) string
}
type Redis struct{
   RedisValue map[string]string
}
func(this *Redis)Set(key string,value string){
   this.RedisValue=make(map[string]string)
   this.RedisValue[key]=value
}
func (this *Redis)Get(key string)string{
   return this.RedisValue[key]
}
//todo 不过这里面如果是interface 要该怎么做呢
//memCache
type MemCache struct{
   RedisValue map[string]string
}
func(this *MemCache)Set(key string,value string){
   this.RedisValue=make(map[string]string)
   this.RedisValue[key]=value
}
func (this *MemCache)Get(key string)string{
   return this.RedisValue[key]
}
type RedisFactory struct{
}
func (this *RedisFactory)DoRedisFactory()Cache{
   return &Redis{}
}
type MemCacheFactory struct{
}
func (this *MemCacheFactory)DoMemCacheFactory()Cache{
   return &MemCache{}
}

测试案例：

func TestFactoryParternImplement(t *testing.T){
   redisFactory :=initial2.RedisFactory{}
   redisStruct:=redisFactory.DoRedisFactory()
   redisStruct.Set("yuwei","bangbangda")
   fmt.Println(redisStruct.Get("yuwei"))
}
