Design And Research Of Distributed Auto Repair Settlement Management System Based On JavaEE

According to the latest data from the Society of Automotive Engineers of China,the number of motor vehicles in China has reached 310 million.With the convenience bringed by cars,it makes the auto repair industry more and more popular.With the development of electronic information technology in the Internet industry,it is imperative to make it easy and safe for users to interact with the auto repair platform.At present,the development of javaEE technology and the popularity of Android smart phones make it possible for the mobile phone to interact with the auto repair management system.Based on the background and current status of the conventional auto repair business,this paper designs an auto repair settlement management system based on the javaEE technology and SSH framework.The interactions among the users,the server and the Android mobile phone are realized,and the push function of personalized maintenance project for old users is provided simultaneously.Technically,the paperless and mobile phone booking service is realized,which not only facilitates the management,but also reminds users to regularly carry out the maintenance of related projects and improves the user experience.Firstly,from the perspective of software engineering,the functional requirements of the system are analyzed,the key technologies such as Model-View-Cotroller Design Pattern,Struts 、 Spring 、 Hibernate and Android are studied to realize the system function.,and these frameworks are applied to the system implementation to make the system with good reliability and expansibility.The system uses Bootstrap technology to implement the responsive layout of the interface.Secondly,this paper investigates the Nginx scheduling algorithm,which realizes the server cluster,alleviates the problem of overloading request in single server,and increases the single visits in the system.In addition,the collaborative filtering algorithm is studied to realize the function of the Android smart terminal to push personalized maintenance project messages tousers.The server realizes data storage and validation through Tomcat server and MySQL database.Using JSON data format based on Http protocol,data interaction between server side and Android intelligent terminal is realized.Finally,the high concurrent access performance and information push of the system are tested.Online test results show that the auto repair settlement management system has realized 29 functions,including system management,parts management,maintenance management and settlement management,etc.It realizes a durable,safe and reliable storage of vehicle maintenance information and the electronic maintenance process.Furthermore,it improves the vehicle maintenance efficiencyand facilitates the manager to understand the business situation of the enterprise.It improves the pressure resistance of the system and provides a safe and reliable solution for enterprise managers.It has the merits of low cost and convenience,which meet the actual needs of managers and ordinary users.
