问题 I'm messing around (for the first time) with Socket programming in C#, I'm making a Skype like application(Video call, IM, file share, screen share) and i have a couple of questions... 1) How should sockets truly work? On the client side I have a while loop which is effictively keeping the socket open, Is this correct? Or should i be closing the socket after each Send/Recieve (Im using BeginSend() and BeginRecieve()) and creating a new socket? interact() is called after the connection has

问题 I am trying to build application by spring boot and Domain Driven Design. I have a problem about Domain model (match with fields of table DB) and View Model (response API). Domain Model: EX: class Name @Getter @NoArgsConstructor @AllArgsConstructor class Name { String value; } class Product @Getter @NoArgsConstructor @AllArgsConstructor class Product{ Name name; } ViewModel: @Data @NoArgsConstructor @AllArgsConstructor class ProductView { //int prodId; String prodName; } Select data DB by

问题 There are so many types of diagrams in UML. I am little confused about which one to use for what. I designed a 3-tier architecture for my web application software using UML Component Diagram. Please see the attached image and tell me if I'm doing this right or wrong. Is this a good idea to use Component Diagram for this architecture? 回答1: Basically I agree with @KeizerHarm's answer. However, there's a flaw in your diagram. Rather than packages you should use components since you put ports on

问题 My system uses a bunch of micro service to process an item and I am planning to create a Stateful MicroService which holds the latest state of the item. In that service, I am planning to store all the item state in a reliable dictionary and whenever an item is accessed update the Last accessed field of the item. My requirement is that, I only want to store the recently used items in the reliable collection and need to move the items that are not accessed for long time to an external storage

问题 After reading different sources about the Ports & Adapters architecture including Alistair Cockburn's original article I am still not sure about the definite meaning of the terms "port" and "adapter" - especially when it comes to mapping these concepts to implementation artifacts. Several sources (e. g. this post) imply that the ports in this architecture pattern are artifacts at the very outside, followed by the adapters in the intermediate layer that translate between the ports and the
