How to realize online Flower Shop Mall by Java

Editor to share with you how Java realizes the online florist mall. I hope you will get something after reading this article. Let's discuss it together.

I. brief introduction of the project

Function: a complete online florist shopping mall system, which supports the registration and landing system messages of foreground members, flower variety selection, details browsing, joining shopping cart, buying flowers, etc.; backstage support administrator's flower species addition, flower details addition and modification, user management, message management, shopping mall news management and so on.

II. Project operation

Environment configuration: Jdk1.8 + Tomcat8.5 + mysql + Eclispe (both supported by IntelliJ IDEA,Eclispe,MyEclispe,Sts)

Project technology: JSP + Servlert + html+ css + JavaScript + JQuery + Ajax + Fileupload and so on.

Mall merchandise query and display code: mall merchandise query: @ Controllerpublic class GoodsController {@ Resource private NewBeeMallGoodsService newBeeMallGoodsService; @ Resource private NewBeeMallCategoryService newBeeMallCategoryService; @ GetMapping ({"/ search", "/ search.html"}) public String searchPage (@ RequestParam Map params, HttpServletRequest request) {if (params.get ("page")) {params.put ("page", 1) } params.put ("limit", Constants.GOODS_SEARCH_PAGE_LIMIT); / / encapsulating classified data if (params.containsKey ("goodsCategoryId") & &!
