《SpringBoot2.0 实战》系列-整合thymeleaf 实现模板文件转word打印

前言

最近，有小伙伴看了我的《模板文件转pdf打印》文章后，私信问我，有没有转word的demo。当时只能遗憾的说没有。所以就有了这篇文章。

如何开始

thymeleaf 依赖包

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

thymeleaf配置

spring:
  # thymeleaf
  thymeleaf:
    prefix: classpath:/templates/
    check-template-location: true
    suffix: .html
    encoding: UTF-8
    mode: HTML
    cache: false
    servlet:
      content-type: text/html

模板准备，此处模板和导出pdf的模板一样

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" xmlns:layout="http://www.w3.org/1999/xhtml" layout:decorator="layout">
<head lang="en">
    <title>Spring Boot Demo - PDF</title>
    <style>
        @page {
            size: 210mm 297mm; /*设置纸张大小:A4(210mm 297mm)、A3(297mm 420mm) 横向则反过来*/
            margin: 0.25in;
            padding: 1em;
            @bottom-center{
                content:"葫芦科技 © 版权所有";
                font-family: SimSun;
                font-size: 12px;
                color:red;
            };
            @top-center { content: element(header) };
            @bottom-right{
                content:"第" counter(page) "页  共 " counter(pages) "页";
                font-family: SimSun;
                font-size: 12px;
                color:#000;
            };
        }
        body{font-family: 'SimSun'}
        h2{color: crimson}
        #myheader{
            width: 500px;
            height: 22px;
            border: 1px solid #000000;
        }
        table, th , td  {
            border: 1px solid grey;
            border-collapse: collapse;
            padding: 5px;
        }
        table tr:nth-child(odd) {
            background-color: #f1f1f1;
        }
        table tr:nth-child(even) {
            background-color: #ffffff;
        }
        #input1{
            border-bottom: 1px solid #000000;
        }
    </style>
</head>
<!--这样配置不中文不会显示-->
<!--<body style="font-family: 宋体">-->
<body style="font-family: 'SimSun'">
<div>1.标题-中文</div>
<h2 th:text="${title}"></h2>

<div>2.按钮:按钮的边框需要写css渲染</div>
<button class="a" style="border: 1px solid #000000"> click me t-p</button>
<div id="divsub"></div>

<div>3.普通div</div>
<div id="myheader">Alice's Adventures in Wonderland</div>

<div>4.图片 绝对定位到左上角(注意:图片必须用全路径或者http://开头的路径,否则无法显示)</div>
<img th:src="${imageUrl}"/>

<div>5.普通table表格</div>
<div>
    <table style="width: 700px">
        <tr>
            <th>姓名</th>
            <th>昵称</th>
            <th>年龄</th>
        </tr>
        <tr th:each="info : ${demoList}">
            <td th:text="${info.name}"></td>
            <td th:text="${info.nick}"></td>
            <td th:text="${info.age}"></td>
        </tr>
    </table>

</div>

<div>6.input控件,边框需要写css渲染 (在模板中一般不用input,因为不存在输入操作)</div>
<div>
    <label>姓名:</label>
    <input id="input1" aria-label="葫芦胡" type="text" value="葫芦胡"/>
</div>
</body>
</html>
