电信 Product & Service Directory

TM Forum推出了一个在线的一站式产品和服务目录,为全球的OSS/BSS专业人士提供了一个全面的平台来查找所需的产品、解决方案和服务信息。该目录依据TM Forum的电信应用地图进行组织,方便买家快速找到合适的产品和服务,同时供应商也能更好地展示其完整的产品系列。
OSS/BSS professionals from around the world now have one place to look for the product,solution or service-related information they need:The TM Forum’s Product & Service Directory.

The TM Forum's Product & Services Directory offers an online,one-stop and comprehensive location,where buyers can get a preview of the products,solutions and services they are looking for,while suppliers can showcase their complete offerings – all at the click of
button.The Product & Services Directory is organized around the TM Forum's Telecom Application Map – a framework for categorizing
applications and services according to specific functional areas.For customers,this makes it easy to locate the right mix of items you
are looking for and for suppliers,you are able to list your offerings to the audiences you want to market to.

内容概要:本文详细介绍了“秒杀商城”微服务架构的设计与实战全过程,涵盖系统从需求分析、服务拆分、技术选型到核心功能开发、分布式事务处理、容器化部署及监控链路追踪的完整流程。重点解决了高并发场景下的超卖问题,采用Redis预减库存、消息队列削峰、数据库乐观锁等手段保障数据一致性,并通过Nacos实现服务注册发现与配置管理,利用Seata处理跨服务分布式事务,结合RabbitMQ实现异步下单,提升系统吞吐能力。同时,项目支持Docker Compose快速部署和Kubernetes生产级编排,集成Sleuth+Zipkin链路追踪与Prometheus+Grafana监控体系,构建可观测性强的微服务系统。; 适合人群:具备Java基础和Spring Boot开发经验,熟悉微服务基本概念的中高级研发人员,尤其是希望深入理解高并发系统设计、分布式事务、服务治理等核心技术的开发者;适合工作2-5年、有志于转型微服务或提升架构能力的工程师; 使用场景及目标:①学习如何基于Spring Cloud Alibaba构建完整的微服务项目;②掌握秒杀场景下高并发、超卖控制、异步化、削峰填谷等关键技术方案;③实践分布式事务(Seata)、服务熔断降级、链路追踪、统一配置中心等企业级中间件的应用;④完成从本地开发到容器化部署的全流程落地; 阅读建议:建议按照文档提供的七个阶段循序渐进地动手实践,重点关注秒杀流程设计、服务间通信机制、分布式事务实现和系统性能优化部分,结合代码调试与监控工具深入理解各组件协作原理,真正掌握高并发微服务系统的构建能力。
以下是类 `Product` 的完整定义及四个函数的实现: ```cpp #include <iostream> #include <string> using namespace std; class Product { string name; // 产品名称 int price; // 产品单价 int quantity; // 剩余产品数量 public: Product(string n, int p, int q); Product operator=(const Product& p); friend bool operator>(const Product& p1, const Product& p2); friend ostream& operator<<(ostream& out, Product& t); }; Product::Product(string n, int p, int q) { name = n; price = p; quantity = q; } Product Product::operator=(const Product& p) { name = p.name; price = p.price; quantity = p.quantity; return *this; } bool operator>(const Product& p1, const Product& p2) { if (p1.price > p2.price) { return true; } else { return false; } } ostream& operator<<(ostream& out, Product& t) { out << "Product Name: " << t.name << endl; out << "Price: " << t.price << endl; out << "Quantity: " << t.quantity << endl; return out; } int main() { Product p1("Product1", 10, 50); Product p2("Product2", 20, 30); cout << "p1: " << endl; cout << p1 << endl; cout << "p2: " << endl; cout << p2 << endl; if (p1 > p2) { cout << "p1 is more expensive than p2." << endl; } else { cout << "p2 is more expensive than p1." << endl; } p2 = p1; cout << "p2 after assignment: " << endl; cout << p2 << endl; return 0; } ``` 输出结果为: ``` p1: Product Name: Product1 Price: 10 Quantity: 50 p2: Product Name: Product2 Price: 20 Quantity: 30 p2 is more expensive than p1. p2 after assignment: Product Name: Product1 Price: 10 Quantity: 50 ``` 其中,运算符重载函数 `operator>` 用于比较两个产品的单价大小,运算符重载函数 `operator<<` 用于输出产品的信息,运算符重载函数 `operator=` 用于实现产品对象之间的赋值操作。在主函数中,我们创建了两个产品对象 `p1` 和 `p2`,并对它们进行了比较和赋值操作。
