Research And Implement Of Constructing Shopping System Based On The J2EE Framework And Search Engine

With the popularity of Internet,the development of E-commerce,as well as changes of the concept of people's lives and consumption,Online Shopping has drawn more attentions increasingly.Combined with Online Shopping System project,the thesis introduces the significance of the research,the status quo and the development of domestic and international Online Shopping System,the main contents of researching of this thesis and the paper's organizational structure.Based on the research of the J2EE specification,the framework technology and MVC pattern,the mechanisms,principles and integrating.approach of Struts,Spring, Hibernate and DWR framework were analyzed carefully.Combined with the application requirements,the system's Use Case Diagram,the function division of modules,the Activity Diagram of some modules,the system process flow,the brief design of all levels and the database design were given.Combined with the example of merchandise management of Online Shopping System,the Sequence Diagram of the system,the Class Diagram,the technical elements, details and the process of application achievement of using the integrated framework at all levels were given.Combined with the application instance of building Blog application,the concrete methods and steps of integrating Spring,Hibernate and DWR framework together were discussed.Aimed at the the discussion of the method of building Data storage,the thesis focuses on building the search engine based on Heritrix,Lucene,Regular Expression and HTMLParser.Heritrix's configuration in the Eclipse environment was summarized. The product information pages of designated web site were analyzed carefully,the Heritrix crawl components was extended.The thesis achieves the information collection, filtration,extraction,storage and indexing of the entire process of application through utilizing relevant techniques and methods.Finally.the thesis summarizes the research work of this subject and gives the future development of the related technologies and further research for the author.
