To build a solid **e-commerce backend using Spring Boot**, you need to design it around core business domains, security, scalability, and integrations.
|
||
|
||
Here’s a structured roadmap 👇
|
||
|
||
---
|
||
|
||
# 1️⃣ Core Functional Modules
|
||
|
||
## 🧑💼 1. User & Authentication Module
|
||
|
||
* User registration & login
|
||
* Role-based access (ADMIN, CUSTOMER, SELLER)
|
||
* JWT or OAuth2 authentication
|
||
* Password encryption (BCrypt)
|
||
* Email verification
|
||
* Forgot/reset password
|
||
|
||
**Technologies**
|
||
|
||
* Spring Security
|
||
* JWT
|
||
* OAuth2 (optional)
|
||
* BCryptPasswordEncoder
|
||

||
# 2️⃣ Recommended Architecture
|
||
|
||
### 🔹 Layered Architecture
|
||
|
||
* Controller layer (REST APIs)
|
||
* Service layer (Business logic)
|
||
* Repository layer (Data access)
|
||
* DTO & Mapper layer (MapStruct recommended)
|
||
|
||
### 🔹 Database
|
||
|
||
* PostgreSQL / MySQL
|
||
* Redis (caching, cart)
|
||
* Elasticsearch (for search, optional)
|
||
|

|
||
|
||
# 3️⃣ Important Technical Features
|
||
|
||
## 🔐 Security
|
||
|
||
* Spring Security
|
||
* JWT authentication
|
||
* CSRF protection
|
||
* CORS config
|
||
* Rate limiting
|
||
* Input validation
|
||
|

|
||
|
||
## ⚡ Performance & Scalability
|
||
|
||
* Caching (Redis)

||
* Pagination
|
||
* Indexing DB columns
|
||
* Async processing
|
||
* Connection pooling (HikariCP)
|
||
|
||
---
|
||
|
||
## 📡 API Design
|
||
|
||
* RESTful endpoints
|
||
* Proper HTTP status codes
|
||
* Exception handling (GlobalExceptionHandler)
|
||
* Swagger / OpenAPI documentation
|
||
|
||

|
||
|
||
## 🧾 Logging & Monitoring
|
||
|
||
* Logback
|
||
* ELK stack
|
||
* Actuator
