The Design And Implementation Of Auto-Aftermarket Search System Based On JavaWeb

Auto-Aftermarket refers to all kinds of services after automobile sale,such as maintenance,cosmetology,modification and so on.At present,compared tothe Japan's and United States' Auto-Aftermarket,there have many shortcomings onChinese.Taking the Internet as a platform,some of the automotive service e-commerce platform is gradually accepted by people,but it is still in the exploratory stage.Different standards,incomplete information,uneven levels,and other issues that make the Auto-Aftermarket chain and Internet is still a long way to go.This paperget referencesfrom United States' Repairpal,AutoMD,Be Car Care Aware and other sites of successful experience,different from most of the domestic electricity supplier nature of the site and the nature of the APP all in one service,pay attention to the national manufacturers of businesses and other basic data collection,design and development of the Auto-Aftermarket information search system.Taking into account the cross platform of the search system and the requirements of reusability and maintainability of the system development and maintenance,the development of the search system uses MVC framework model,which is implemented by JSP+Servlet+JavaBean.The system interface uses jQuery and AJAX technology to realize the asynchronous update of the page,and improve the performance of the software.In order to ensure the user's satisfaction with the search results,the string processing flow is designed by the way of inputting the search string.According tothe characteristics that it have many proper nouns on the industry,thesis uses word omni-segmentationalgorithmbased on a dictionary for Chinese word segmentation,and use the N-Gram model to select the optimal solution of the segmentation results.At the same time,in order to protect the interests of the owners of the system,and improve the security of enterprise informationand other important content.Based on the comparison of the previous algorithms,a database encryption and decryption model is established.Research into the process of encryption and decryption of the AES algorithm,and put forward the improvement scheme of key expansion algorithm.The encryption model of search system is also established.Finally,the improved algorithm and function of the system are tested,and the solutions to the problems are put forward.theAuto-Aftermarket information search system is mainly for the industry,manufacturers,merchants and repair shop and other users,to provide a nationwide business communication and advertising media platform.At the same time take into account the individual owners of users,for the user to choose auto parts shop,repair shop,etc.provides a way.The system has established the perfect enterprise information database,has established the data base for the future business expansion,has gathered the popularity.At the same time,the national automobile market is more closely linked to promote the industrial chain and the Internet,better with international standards.
