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。
—
使用 Spring Initializr 生成一个Spring Boot项目:
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
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
在model
包中创建实体类,例如User
、Product
、Comment
、Like
等。
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
}
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
}
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
}
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
}
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> {
}
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 {
@Autowired
private 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);
}
}
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 {
@Autowired
private ProductService productService;
@GetMapping
public 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";
}
@PostMapping
public 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";
}
}
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>Productstitle>
head>
<body>
<h1>Productsh1>
<a href="/products/new">Add New Producta>
<table>
<thead>
<tr>
<th>IDth>
<th>Nameth>
<th>Descriptionth>
<th>Imageth>
<th>Actionsth>
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})}">Edita>
<a th:href="@{/products/delete/{id}(id=${product.id})}">Deletea>
td>
tr>
tbody>
table>
body>
html>
product-form.html
DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Product Formtitle>
head>
<body>
<h1>Product Formh1>
<form th:action="@{/products}" th:object="${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">Savebutton>
form>
body>
html>
在IDE中运行DigitalShareApplication.java
,访问http://localhost:8080/products
即可看到数码产品列表页面。
