java将html转成图片

java 将html转成图片

- 1.导入jar
- 2.代码
- 3.展示结果
- 4.注意事项

最近有一个需求需要根据指定的样式生成图片，使用java原生技术有些麻烦，所以上网搜了下案例，最后发现最好用的还是html2image，这里进行简单总结下。

1.导入jar

 <!-- 用于将html转图片--><dependency><groupId>gui.ava</groupId><artifactId>html2image</artifactId><version>2.0.1</version></dependency>

2.代码

下面是示例代码，这里使用String的方式传入html信息，除了直接传入还支持传入文件流、传入文件等其他方式，差距不大，这里不列举其他方式的细节了。

import gui.ava.html.parser.HtmlParser;
import gui.ava.html.parser.HtmlParserImpl;
import gui.ava.html.renderer.ImageRenderer;
import gui.ava.html.renderer.ImageRendererImpl;public class TestTableToImage {public static void main(String[] args) throws Exception {HtmlParser htmlParser = new HtmlParserImpl();String HtmlTemplateStr = "<html lang=\"zh-CN\">\n" +"<head>\n" +"    <meta charset=\"UTF-8\">\n" +"    <title>入库单</title>\n" +"</head>\n" +"<body>\n" +"\t<!--外层的表格 -->\n" +"\t<table style=\"border: 2px solid black;padding: 10px \"  cellpadding=\"5\" align=\"center\" >\n" +"\t\n" +"\t\t<tr >\n" +"\t\t\t<th style=\"font-size:25px;height: 60px;\" align=\"center\">入库单</th>\n" +"\t\t</tr>\n" +"\t\t\n" +"\t\t<tr>\n" +"\t\t\t<th>\n" +"\t\t\t\t<table border=\"1\" style=\"border-color: #ccc;\" cellspacing=\"0\" cellpadding=\"15\" width=\"900px\">\n" +"\t\t\t\t\t<tr  style=\"color: #696969;height: 60px;\">\n" +"\t\t\t\t\t\t<th style=\"width: 150px;\">调度单号</th> <th colspan=\"2\" style=\"width: 300px;\">调度单号22</th>\n" +"\t\t\t\t\t\t<th style=\"width: 150px;\">客户名称</th> <th colspan=\"2\" style=\"width: 300px;\">客户名称22</th>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t\n" +"\t\t\t\t\t<tr  style=\"color: #696969;height: 50px;\">\n" +"\t\t\t\t\t\t<th >车牌照号</th> <th colspan=\"2\" style=\"width: 300px;\">车牌照号22</th>\n" +"\t\t\t\t\t\t<th>装运时间</th> <th colspan=\"2\" style=\"width: 300px;\">装运时间22</th>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t<tr height=\"50px;height: 50px;\">\n" +"\t\t\t\t\t\t<td colspan=\"6\" style=\"font-size:23px;color: #696969\" align=\"center\">货物信息</td>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t<tr  style=\"color: #696969;height: 50px;\">\n" +"\t\t\t\t\t\t<th>钢卷号</th> <th colspan=\"2\" style=\"width: 300px;\">钢卷号22</th>\n" +"\t\t\t\t\t\t<th>磅单号</th> <th colspan=\"2\" style=\"width: 300px;\">磅单号22</th>\n" +"\t\t\t\t\t\t\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t<tr  style=\"color: #696969;height: 50px;\">\n" +"\t\t\t\t\t\t<th>材质</th><th style=\"width: 150px;\">材质22</th>\n" +"\t\t\t\t\t\t<th>规格型号</th><th style=\"width: 150px;\">规格型号22</th>\n" +"\t\t\t\t\t\t<td>货物名称</td><th style=\"width: 150px;\">货物名称22</th>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t<tr  style=\"color: #696969;height: 50px;\" align=\"center\">\n" +"\t\t\t\t\t\t\n" +"\t\t\t\t\t\t<td>件数</td> <th colspan=\"2\" style=\"width: 300px;\">件数22</th>\n" +"\t\t\t\t\t\t<td>重量</td> <th colspan=\"2\" style=\"width: 300px;\">重量22</th>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t<tr  style=\"color: #696969;height: 50px;\" align=\"center\">\n" +"\t\t\t\t\t\t<td colspan=\"6\" style=\"font-size:23px;color: #696969\">客户信息</td>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t<tr  style=\"color: #696969;height: 50px;\">\n" +"\t\t\t\t\t\t<th>收货联系人</th> <th colspan=\"2\" style=\"width: 300px;\">收货联系人22</th>\n" +"\t\t\t\t\t\t<th>收货人电话</th> <th colspan=\"2\" style=\"width: 300px;\">收货人电话22</th>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t<tr  style=\"color: #696969;height: 50px;\">\n" +"\t\t\t\t\t\t<th >库房名称</th> <th colspan=\"2\" style=\"width: 300px;\">库房名称22</th>\n" +"\t\t\t\t\t\t<th >库房地址</th> <th colspan=\"2\" style=\"width: 300px;\">库房地址22</th>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t\n" +"\t\t\t\t\t<!--\n" +"\t\t\t\t\t<tr style=\"color: #696969;height: 50px;\">\n" +"\t\t\t\t\t\t<th >收货地点</th> <th colspan=\"5\" style=\"width: 750px;\">收货地点22</th>\n" +"\t\t\t\t\t</tr>\n" +"\t\t\t\t\t -->\n" +"\t\t\t\t</table>\n" +"\t\t\t</th>\n" +"\t\t\t\n" +"\t\t</tr>\n" +"\t\t\n" +"\t\t<tr style=\"height: 150px;\">\n" +"\t\t\t<th></th>\n" +"\t\t</tr>\n" +"\t\t\n" +"\t</table>\n" +"</body>\n" +"</html>";htmlParser.loadHtml(HtmlTemplateStr);ImageRenderer imageRenderer = new ImageRendererImpl(htmlParser);imageRenderer.setWidth(955);imageRenderer.saveImage("D:\\66.png");}}
