SSM distributed Architecture e-commerce project-10 build front-Office system

The technology used

Background technology: Spring SPRINGMVC Mybatis (NO).
Foreground technology: HTML, CSS, JS
If you do not use MyBatis, the product's data comes from. – from MySQL Database
Ways to get Data:
1. Getting from JDBC
A) advantages
I. Direct, access to short, simple
b) Disadvantages
I. Data is unsafe for back-end system teams (as long as the open account is a read-only account)
Ii. the front-end system team needs to have the learning cost to use the database
Iii. dependency, coupling is too high, the backend team modifies the database structure, then other teams must follow the change logic to use
Iv. go directly to the database query, unable to add cache logic
2, through the background system interface to obtain
A) advantages
I. The coupling is reduced, and the back-end team simply ensures that the return data format of the interface does not change, and other teams do not need to upgrade
II. Data security
Iii. front-end team does not need to learn the underlying database structure of the backend team
Iv. back-end teams can add cache logic at the interface
b) Disadvantages
I. Get a long path (not a real disadvantage) create Taotao-web

Writing Indexcontroller

Package Com.taotao.web.controller;

Import Org.springframework.stereotype.Controller;
Import org.springframework.web.bind.annotation.RequestMapping;
Import Org.springframework.web.bind.annotation.RequestMethod;
Import Org.springframework.web.servlet.ModelAndView;


@RequestMapping ("index")
@Controller public
class Indexcontroller {


    /**
     * Home
     * * 
     @return
     *
    /@RequestMapping (method = requestmethod.get) public
    Modelandview Index () {
        Modelandview mv = New Modelandview ("index");
        return mv;
    }

}

Configuring hosts and Nginx

To run a test discovery:
Www.taotao.com will not find the page:

www.taotao.com/index.html to get the page

Because the input www.taotao.com, the default is to find the index.jsp, does not meet the *.html rules.

re-Test after modification:
