typical e-commerce system ( online shopping platform ) . Dangdang system simulates some features .
2. functional requirements
1) user management module ( 3 days ) user
realized login, registration function
2) Products Module ( 2 days ) main
achieve the main interface and category browsing
3) shopping cart module ( 1.5 days ) cart
to buy it , the number of changes , delete functions
4) generate orders module ( 1.5 days ) order
order confirmation , fill in the shipping address , function generate orders
3. Technique
1) Technical Architecture
Struts2, JDBC ( connection pools ), jQuery, Ajax
2) design ideas
MVC and hierarchical design ideas
a display layer :. JSP components (jQuery, Ajax) .
b control layer : Struts2 controller components , Action Component
c business layer :. Bean Components
d Data Access Layer :. DAO component (JDBC)
4. database design
1) Database import
create database dangdang; / / Create a library
use dangdang; / / enter dangdang library
set names utf8; / / set the connection and send SQL coding
source path / dangdang.sql; / / import the sql file
2) Data table function
a.d_user ( user information table )
stores user information, login and registration functions involving
b.d_receive_address ( shipping address information table )
stores shipping address information, fill out the shipping address function involving
c.d_category ( Class Information Sheet )
category information stored books involving the left main interface menu features category
d.d_book ( Book Information Sheet )
book stores specific information , browsing and other functions related to product
e.d_product ( Product Information Sheet )
storing various types of products common information field.
f.d_category_product ( category and product mapping table )
stores and products containing relations between classes , involving product browsing
g. d_order ( Order Information Sheet )
stores order information, involve creating order functions
h. d_item ( Order Details )
stores product information in the purchase order , involves creating order functions.
5. structures engineering structures
1) the need to introduce development package
struts2 Development Kit
jdbc Development Kit
dbcp connection pool Development Kit
2) src file structure
org.tarena.dang.action: control layer action of the user module :
org.tarena.dang.action.user
org.tarena.dang.action.main: Products of action
org.tarena.dang.action.order: Orders for action
org.tarena.dang.action.cart: shopping cart action
org.tarena.dang.service: business layer
org.tarena.dang.dao: Data Access Layer
org.tarena.dang.entity: entity class
org.tarena.dang.util: Tools
org.tarena.dang.interceptor: Interceptor
3) struts configuration file structure
web.xml ( Configuration Filter Controller )
struts.xml (struts main configuration file )
struts-user.xml ( user module configuration file )
struts-main.xml ( Read module configuration file )
struts-order.xml ( Orders module configuration file )
struts-cart.xml ( shopping cart module configuration file )
4) WebRoot file structure
/ user / *: User Management JSP
/ cart / *: JSP shopping cart
/ order / *: JSP Order
/ main / *: product browsing JSP
/ common / *: headers, footers and other common JSP
/ js / *: Place js script file
/ css / *: place the css style file
/ images / *: Place page image files
/ productImages / *: Place Product Image
Advantages
----------------- ----------------- connection pool
a. Connection object can manage and control the Connection number in a safe range. Improve access security database.
b. connection pool of Connection objects remain connected with the database , to avoid frequent connections created and destroyed .
============ user management module ==============
1. registration requirements
1) form validation ( using js + Ajax)
Email: non-empty , format, uniqueness (ajax)
Nickname: non-empty , the format
Password: non-empty , the format
Confirm Password: non-empty , consistent with the password
verification code : non-empty , correctness (ajax)
2) information into the form data sheet d_user
entity class writing , DAO, Action
3) send a verification code to the user's mailbox
introduced commons-email.jar, email.jar
reference EmailUtil tools code
4) into the mailbox authentication page verify_form.jsp
2. mail verification
1) Forms Authentication
verification code : non-empty , correctness (ajax)
right after the jump to success prompt interface : window.location = "register_ok.jsp";
2) Action Logic
a. use verification code to d_user check .
b if correct, will update is_email_verify field d_user into Y; incorrect verify_form.jsp prompted "Authentication failed"
c. jumps to register_ok.jsp
3. User Login
1) Forms Authentication
Email: non-empty , the format
Password: non-empty
2) Action Logic
a. Detection Email and password are correct , failed back login_form.jsp Tips
b. detection is_email_verify mailbox is validated, not by going verify_form.jsp
c. last_login_time update last login time and IP address last_login_ip.
d. the user information into the session.
e. correctly enter / main / main.jsp
4.main.jsp page header section , showing the status of the user is logged in
If a user is logged in, display the "Welcome XXX, [ Logout ]"
If the user is not logged Show "[ Login ] [ Register ]"
database model
Home Show :
registration page :
Verify E-mail:
authentication is successful :
user login status:
In fact, there are many defects in the project need to complete projects , we can modify , which has a bug on the shopping cart , into question , we all look for it
