Design And Implementation Of Distributed Mall Based On SSM

With the development of social economy,the rise of market vitality and the promotion of Internet technology,housing economy has become a new economic model.People can consume and buy things they need through the Internet anytime and anywhere.Electronic mall is an important part of the residential economic model.Relying on the distributed development technology,it integrates the functions of commodity display,commodity selection,shopping cart,purchase and payment,and provides one-stop online shopping service for people.Compared with offline store shopping,online virtual platform shopping is not limited by region and time.During special festivals and activities,a large number of users will log in to electronic mall at the same time to use services.And according to the changing needs,electronic mall needs to change the types of services and adjust the service capabilities in real time.Therefore,under the demand of high concurrency,high availability and extensibility,the traditional vertical single architecture of electronic mall can not meet this demand.It needs to use advanced framework technology and service-oriented distributed technology to complete the construction of electronic mall.The system uses SSM framework based on MVC design concept,i.e.Spring container framework,Spring MVC framework and Mybatis persistence layer framework.Maven,a project management tool,integrates the three frameworks for project construction and dependency management.Meanwhile,the system uses serviceoriented distributed technology,such as Dubbo,redis,ActiveMQ,etc.Based on the above technology,the functions of login and registration,shopping cart,order,search,goods management and content management of the background management system are realized.Users use the front-end portal system to complete online goods purchase,goods collection,order payment,and the system administrator uses the back-end management system to maintain and manage the goods and content of the mall.In the non functional aspect,the system is decoupled and layered,easy to expand and highly available.The introduction of the framework reduces the development cost.The repeated construction code is completed by the framework itself,and the development only needs to focus on the preparation of business logic.The introduction of distributed cluster enables the system to adjust the number of servers in real time according to the level of concurrency,saves the running cost,and conveniently replaces some problem modules without affecting the normal operation of other services,so as to keep the whole system running normally.
