Session 1: Bootstrap Guidelines
Date: 2026-04-27 Task: Bootstrap Guidelines
Summary
Populated Trellis backend/frontend specs for the JSP + Servlet + MySQL + Tomcat library management system and archived the bootstrap task.
Main Changes
Project Requirements From Developer
Source
Captured on 2026-04-27 during the Trellis bootstrap-guidelines task from developer-provided project facts.
Architecture And Stack
- The system uses B/S architecture with a typical layered design.
- The application stack is JSP + Servlet, MySQL, Tomcat, developed in IDEA.
- The layers are presentation, controller, business/service, DAO, and data.
Data Layer
MySQL is the data layer and stores:
- Book information.
- Book category information.
- Reader information.
- Borrowing records.
- Administrator information.
- Role and permission information.
- System logs.
Core entity tables should include book information, book categories, reader information, borrowing records, administrators, role permissions, and system logs. Use primary keys and foreign keys to preserve data integrity.
DAO Layer
The data access layer uses DAO classes to perform database CRUD. DAOs should own SQL/database access concerns and should not contain presentation or business workflow logic.
Business And Service Layer
The service layer handles:
- Book warehousing/intake.
- Borrowing and returning.
- Inventory status updates.
- Overdue statistics.
- Permission checks.
Controller Layer
Servlet controllers handle request dispatch, parameter validation, and result return. Controllers should coordinate request/response flow and call services for business behavior.
Presentation Layer
JSP/CSS pages handle page display and user interaction.
The frontend approach is image-first: UI should be designed or generated as images first, then JSP/CSS pages should restore and implement the image faithfully.
Core Modules
- Login and permission management for administrator, librarian, and reader roles.
- Book information management for create, update, delete, category maintenance, and inventory status.
- Reader information management for profiles, borrowing eligibility, and contact information.
- Borrowing and return management for borrow, return, renew, overdue handling, and automatic collection status updates.
- Book search and statistics for combined search by title, author, category, and ID, plus borrowing rankings, inventory reports, and overdue reports.
- System maintenance and logs for key operation logs, data backup support, and exception tracing.
