1. 引入 Thymeleaf 依赖

首先，你需要在 pom.xml 文件中引入 Thymeleaf 的依赖。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

2. 创建控制器

在 Spring Boot 中创建一个控制器，用来处理请求并传递热点资源和推荐资源的数据到前端。

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

import java.util.ArrayList;
import java.util.List;

@Controller
public class ResourceController {

    @GetMapping("/resources")
    public String showResources(Model model) {
        // 假设从数据库或者其他服务中获取热点资源和推荐资源
        HotResource hotResource = new HotResource("热点资源1", "12345", "67890");

        List<RecommendedResource> recommendedResources = new ArrayList<>();
        recommendedResources.add(new RecommendedResource("推荐资源1", "54321"));
        recommendedResources.add(new RecommendedResource("推荐资源2", "98765"));
        recommendedResources.add(new RecommendedResource("推荐资源3", "45678"));
        recommendedResources.add(new RecommendedResource("推荐资源4", "87654"));
        recommendedResources.add(new RecommendedResource("推荐资源5", "12321"));

        // 将数据传递到模板中
        model.addAttribute("hotResource", hotResource);
        model.addAttribute("recommendedResources", recommendedResources);

        return "resources"; // 返回模板名称，Thymeleaf 会渲染 resources.html
    }
}

class HotResource {
    private String name;
    private String resourceId;
    private String recordId;

    // 构造函数、getter和setter
    public HotResource(String name, String resourceId, String recordId) {
        this.name = name;
        this.resourceId = resourceId;
        this.recordId = recordId;
    }

    public String getName() {
        return name;
    }

    public String getResourceId() {
        return resourceId;
    }

    public String getRecordId() {
        return recordId;
    }
}

class RecommendedResource {
    private String name;
    private String resourceId;

    // 构造函数、getter和setter
    public RecommendedResource(String name, String resourceId) {
        this.name = name;
        this.resourceId = resourceId;
    }

    public String getName() {
        return name;
    }

    public String getResourceId() {
        return resourceId;
    }
}

3. 修改 Thymeleaf 模板

在 resources/templates 目录下创建 resources.html，并使用 Thymeleaf 语法动态渲染数据。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>资源推荐</title>
    <style>
        /* 样式部分和前面的保持一致 */
        body {
            font-family: 'Arial', sans-serif;
            background-color: #e0f7fa; /* 清爽的淡蓝色背景 */
            margin: 0;
            padding: 0;
            height: 100vh;
        }
        .container {
            width: 70vw;
            padding: 20px;
            background-color: #fff;
            border-radius: 8px;
            box-shadow: 0 4px 10px rgba(0, 0, 0, 0.1);
            margin: 0 auto;
            position: relative;
            top: 0;
        }
        .section {
            margin-bottom: 30px;
        }
        .section h2 {
            text-align: center;

            font-size: 20px;
            border-bottom: 2px solid #eee;
            padding-bottom: 10px;
        }
        .section .item {
            margin: 10px 0;
            padding: 15px;

            transition: all 0.3s ease;
        }
        .section .item:hover {
            box-shadow: 0 6px 12px rgba(0, 0, 0, 0.1);
            transform: translateY(-3px);
        }
        .section .item a {
            display: block;
            text-decoration: none;
            color: #00796b;
            font-size: 16px;
            font-weight: bold;
            transition: color 0.3s ease;
        }
        .section .item a:hover {
            color: #004d40;
        }
        .section .item p {
            margin: 5px 0;
            color: #555;
            font-size: 14px;
        }
        .hot-resource {
            border: 2px solid #f44336;
            background-color: #ffebee;
        }
        .recommended-resource {
            border: 2px solid #4caf50;

        }
        .scrollable-content {
