搭建一个基于Spring Boot的数码分享网站可以涵盖多个功能模块，例如用户管理、数码产品分享、评论、点赞、收藏、搜索等。以下是一个简化的步骤指南，帮助你快速搭建一个基础的数码分享平台。

1. 项目初始化

使用 Spring Initializr 生成一个Spring Boot项目：

访问 Spring Initializr。
选择以下依赖：
- Spring Web（用于构建RESTful API或MVC应用）
- Spring Data JPA（用于数据库操作）
- Spring Security（用于用户认证和授权）
- Thymeleaf（可选，用于前端页面渲染）
- MySQL Driver（或其他数据库驱动）
- Lombok（简化代码）
点击“Generate”下载项目。

2. 项目结构

项目结构大致如下：

src/main/java/com/example/digitalshare├── controller├── service├── repository├── model├── config└── DigitalShareApplication.java
src/main/resources├── static├── templates└── application.properties

3. 配置数据库

在application.properties中配置数据库连接：

spring.datasource.url=jdbc:mysql://localhost:3306/digital_share
spring.datasource.username=root
spring.datasource.password=yourpassword
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

4. 创建实体类

在model包中创建实体类，例如User、Product、Comment、Like等。

用户实体类 (`User`)

package com.example.digitalshare.model;import javax.persistence.*;
import java.util.Set;@Entity
public class User {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long id;private String username;private String password;private String email;@OneToMany(mappedBy = "user", cascade = CascadeType.ALL)private Set<Product> products;@OneToMany(mappedBy = "user", cascade = CascadeType.ALL)private Set<Comment> comments;@OneToMany(mappedBy = "user", cascade = CascadeType.ALL)private Set<Like> likes;// Getters and Setters
}

数码产品实体类 (`Product`)

package com.example.digitalshare.model;import javax.persistence.*;
import java.util.Set;@Entity
public class Product {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long id;private String name;private String description;private String imageUrl;@ManyToOne@JoinColumn(name = "user_id")private User user;@OneToMany(mappedBy = "product", cascade = CascadeType.ALL)private Set<Comment> comments;@OneToMany(mappedBy = "product", cascade = CascadeType.ALL)private Set<Like> likes;// Getters and Setters
}

评论实体类 (`Comment`)

package com.example.digitalshare.model;import javax.persistence.*;@Entity
public class Comment {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long id;private String content;@ManyToOne@JoinColumn(name = "user_id")private User user;@ManyToOne@JoinColumn(name = "product_id")private Product product;// Getters and Setters
}

点赞实体类 (`Like`)

package com.example.digitalshare.model;import javax.persistence.*;@Entity
public class Like {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long id;@ManyToOne@JoinColumn(name = "user_id")private User user;@ManyToOne@JoinColumn(name = "product_id")private Product product;// Getters and Setters
}

5. 创建Repository接口

在repository包中创建JPA Repository接口。

package com.example.digitalshare.repository;import com.example.digitalshare.model.Product;
import org.springframework.data.jpa.repository.JpaRepository;public interface ProductRepository extends JpaRepository<Product, Long> {
}

6. 创建Service层

在service包中创建服务类。

package com.example.digitalshare.service;import com.example.digitalshare.model.Product;
import com.example.digitalshare.repository.ProductRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;@Service
public class ProductService {@Autowiredprivate ProductRepository productRepository;public List<Product> getAllProducts() {return productRepository.findAll();}public Product getProductById(Long id) {return productRepository.findById(id).orElse(null);}public Product saveProduct(Product product) {return productRepository.save(product);}public void deleteProduct(Long id) {productRepository.deleteById(id);}
}

7. 创建Controller层

在controller包中创建控制器类。

package com.example.digitalshare.controller;import com.example.digitalshare.model.Product;
import com.example.digitalshare.service.ProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;@Controller
@RequestMapping("/products")
public class ProductController {@Autowiredprivate ProductService productService;@GetMappingpublic String listProducts(Model model) {model.addAttribute("products", productService.getAllProducts());return "products";}@GetMapping("/new")public String showProductForm(Model model) {model.addAttribute("product", new Product());return "product-form";}@PostMappingpublic String saveProduct(@ModelAttribute Product product) {productService.saveProduct(product);return "redirect:/products";}@GetMapping("/edit/{id}")public String showEditForm(@PathVariable Long id, Model model) {model.addAttribute("product", productService.getProductById(id));return "product-form";}@GetMapping("/delete/{id}")public String deleteProduct(@PathVariable Long id) {productService.deleteProduct(id);return "redirect:/products";}
}

8. 创建前端页面

在src/main/resources/templates目录下创建Thymeleaf模板文件。

`products.html`

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head><title>Products</title>
</head>
<body><h1>Products</h1><a href="/products/new">Add New Product</a><table><thead><tr><th>ID</th><th>Name</th><th>Description</th><th>Image</th><th>Actions</th></tr></thead><tbody><tr th:each="product : ${products}"><td th:text="${product.id}"></td><td th:text="${product.name}"></td><td th:text="${product.description}"></td><td><img th:src="${product.imageUrl}" width="100" /></td><td><a th:href="@{/products/edit/{id}(id=${product.id})}">Edit</a><a th:href="@{/products/delete/{id}(id=${product.id})}">Delete</a></td></tr></tbody></table>
</body>
</html>

`product-form.html`

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head><title>Product Form</title>
</head>
<body><h1>Product Form</h1><form th:action="@{/products}" th:object="${product}" method="post"><input type="hidden" th:field="*{id}" /><label>Name:</label><input type="text" th:field="*{name}" /><br/><label>Description:</label><input type="text" th:field="*{description}" /><br/><label>Image URL:</label><input type="text" th:field="*{imageUrl}" /><br/><button type="submit">Save</button></form>
</body>
</html>
