java 使用freemarker生成html

技术方案

java 1.8 + Freemarker

maven依赖

<dependency>
    <groupId>org.freemarker</groupId>
    <artifactId>freemarker</artifactId>
    <version>2.3.31</version> <!-- 请使用最新版本 -->
</dependency>

创建模板文件，保存至src/main/resources/templates/，文件名为template.html

<!DOCTYPE html>
<html lang="zh">
<head>
    <meta charset="UTF-8"></meta>
    <meta name="viewport" content="width=device-width, initial-scale=1.0"></meta>
    <title>${name}的简历</title>
    <style>
        @page {
            size: A4;
            margin: 5mm 10mm; /* 上下和左右两个方向的边距分别为 10mm 和 20mm */
        }
        body {
            font-family: Arial, sans-serif;
            margin: 0;
            padding: 0;
            background-color: #f4f4f9;
        }
        .container {
            width: 80%;
            margin: 0 auto;
            padding: 20px;
            background-color: #ffffff;
            box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
        }
        h1 {
            text-align: center;
            color: #333;
        }
        .section-title {
            color: #4CAF50;
            margin-top: 20px;
        }
        .section-content {
            margin: 10px 0;
        }
        .contact-info, .skills, .experience, .education {
            margin-bottom: 20px;
        }
        .experience, .education {
            margin-top: 10px;
        }
        ul {
            list-style-type: none;
            padding-left: 0;
        }
        li {
            margin-bottom: 10px;
        }
        .job, .degree {
            font-weight: bold;
        }
    </style>
</head>



<body>

<div class="container">
    <h1>${name}的简历</h1>

    <!-- 联系信息 -->
    <div class="contact-info">
        <h2 class="section-title">联系信息</h2>

            <p>${job.description}</p>
        </div>
        </#list>
    </div>

    <!-- 教育背景 -->
    <div class="education">
        <h2 class="section-title">教育背景</h2>
        <#list education as degree>
            <div class="degree">

            </div>
        </#list>
    </div>
</div>
