NIST Under Federal Audit for NVD Processing Backlog and Delays
As vulnerability data bottlenecks grow, the federal government is formally investigating NIST’s handling of the National Vulnerability Database.
github.com/framework-arp/arp4g-mongodb
这是ARP4G的MongoDB实现。
//定义仓库
type OrderRepository interface {
Take(ctx context.Context, id any) (order *Order, found bool)
}
//定义Service
type OrderService struct {
orderRepository OrderRepository
}
//获得mongodb客户端
mongoClient, err := mongo.Connect(context.Background(), options.Client().ApplyURI(
"mongodb://localhost:27017/orders"))
if err != nil {
panic(err)
}
//生成仓库的mongodb实现
mongoOrderRepo := mongorepo.NewMongodbRepository(mongoClient, "orders", "Order", func() *Order { return &Order{} })
//使用仓库生成Service
orderService := &OrderService{mongoOrderRepo}
这里使用NewMongodbRepository打包生成了MongoDB的仓库实现,仓库会使用MongoDB持久化,也会用MongoDB实现互斥锁。
func NewMongodbRepositoryWithMutexesimpl[T any](client *mongo.Client, database string, collection string, newEmptyEntity arp.NewZeroEntity[T], mutexesimpl arp.Mutexes) arp.QueryRepository[T]
也可以使用NewMongodbRepositoryWithMutexesimpl函数选择不同的互斥锁实现,比如,持久化到MongoDB,但是用Redis实现互斥锁
