3.html页面
注意：html格式非常严格，图片地址这里用的是绝对路径（file:///D:/WorkSpace/IdeaProjects/pdf/src/main/resources/static/images/1.jpg）
如果是相对路径要在后台设置
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8"/>
<title>Title</title>
<style>
/*没有background-color生成的pdf一部分会是空白*/
body{ text-align:center;border: 0px;margin: 0px;background-color:#FFFFFF;}
.div{ margin:0 auto; width:1188px; height:auto;}
body {
/*中文支持*/
font-family:SimSun;
}
</style>
</head>
<body>
<div class="div">
<div>
<h2>123我</h2>
<img src="file:///D:/WorkSpace/IdeaProjects/pdf/src/main/resources/static/images/1.jpg" style="width: 20px;height: 20px"/>
<table border="1" cellspacing="0">
<tr>
<td>eE额33</td>
<td>eE额33</td>
</tr>
<tr>
<td>eE额33</td>
<td>eE额33</td>
</tr>
<tr>
<td>eE额33</td>
<td>eE额33</td>
</tr><tr>
<td>eE额33</td>
<td>eE额33</td>
</tr>
</table>
</div>
</div>
</body>
</html>4.生成pdf
超出页面长度时会自动分页
