1.引入jar包（pom）
<dependency>
<groupId> freemarker</groupId>
<artifactId> freemarker </artifactId>
<version>2.3.19</version>
2.准备html模板(此处指粘贴部分)
3.撸代码
//替换参数
Map map =new HashMap();
map.put("title",record.getTitle());
map.put("summary", record.getSummary());
map.put("url", record.getUrl());//链接
map.put("coverImgUrl",faviconIco);
map.put("ideaForwardId",record.getId());
Configuration configuration =new Configuration();
configuration.setDirectoryForTemplateLoading(new File(templatePath));//此文件为上文贴出模板
configuration.setObjectWrapper(new DefaultObjectWrapper());
configuration.setDefaultEncoding("utf-8");
Template template = configuration.getTemplate("forwardTemplate.html", "UTF-8");
template.setEncoding("UTF-8");
String path =new StringBuilder(localForwardHtml).append(md5).append("/index.html").toString();
File file =new File(path);
if (!file.exists()) {
FileUtil.createFile(path);//创建新文件
}
Writer writer =new OutputStreamWriter(new FileOutputStream(new File(path)), "utf-8");
template.process(param, writer);//替换参数
writer.flush();
writer.close();
注：模板中替换参数后加“！”是站位符，防止传入参数为空报错！
