【Example function】
front desk:
1). User module functions include:
* User registration:
> The form page is verified by jQuery (including ajax asynchronous requests)
# Check when the input box loses focus;
# Validate all input boxes when submitting;
# Hide the error message when the input box gets focus.
> The form page uses a one-time graphic verification code;
> Do the form validation again in the servlet.
> When the registration is successful, use javaMail to send an activation email to the registered user, the email contains a link for activation, and the link contains the activation code parameter;
* User activation: query the user through the activation code, if the user cannot be queried, then the activation code is invalid! The activation code is generated using uuid!
* User login:
> The form validation is the same as the registration function;
> When the login is successful, the current user name will be saved in the cookie, so that it can be displayed in the input box of the login page!
* User exit: destroy session
2). Classification module
* Query all categories:
> There are 1 and 2 classifications
> Use accordion menus (Javascript components) to display categories in the page.
3). Book module:
* Query by category
* Search by author
* Search by publisher
* Fuzzy query by book title
* Multi-condition combination query
* Query by id
Except for querying by id, the others are paging queries.
Technical Difficulties:
> Combined query: Piece together SQL statements based on multiple conditions.
> Conditional paging query: Conditions may be lost. Use a custom PageBean to pass pagination data!
> Pagination on the page: the display of the page number list is not easy to calculate!
4). Shopping cart module:
* add entry
* Modify the number of entries
* delete entry
* Bulk delete entries
* my shopping cart
* Query the checked item
The shopping cart is not using sesson or cookies, but is stored to the database.
Technical Difficulties:
> When adding an entry, if the entry for the same book is added twice, it is not added, but merged;
> Request the server side when using ajax when modifying the quantity, and the server side returns json.
> A lot of js code
5). Order module:
* Generate orders
* My Order
* View order details
* s
* Order confirmation receipt
* cancel order
Technical Difficulties:
> Using epay online payment platform:
# Connect with the Yibao payment gateway according to the payment scope of Yibao.
# Receive the two response mechanisms of Yibao, and reply to the point-to-point response.
# Handle the repeated confirmation of the database generated by multiple responses.
Backstage
1). Administrator
* Admin login
2). Classification management
* Added 1st class category
* Add 2-level category: You need to specify the 1-level category for the 2-level category
* Edit level 1 category
* Edit Level 2 Category: You can modify the Level 1 category you belong to
* Delete level 1 category: When there is a subcategory, it cannot be deleted
* Delete Level 2 Category: Books cannot be deleted when there are books under the current Level 2 category
* View all categories
3). Book management
* Various inquiries: same as the front desk
* Add books:
> Upload Image
> The page uses a dynamic drop-down list to display the second-level category. When the first-level category is specified, the second-level category drop-down list dynamically displays the names of all the second-level categories under the first-level category.
* Modify Book: Similar to adding a book, also uses a dynamic drop-down list
* Deleting a book: You need to delete the picture corresponding to the book, and then delete the book
4). Order management
* Various inquiries
* Order shipped
* cancel the order
