该模块用于相关内容导出功能，先读取模板文件，再替换模板中的内容，最后直接以流的形式提供下载。主要代码如下：
String templateContent = "";
// 读取模板文件
FileInputStream fileinputstream = new FileInputStream(filePath);
InputStreamReader isr = new InputStreamReader(fileinputstream, "utf-8");
BufferedReader br = new BufferedReader(isr);
String line = null;
while ((line = br.readLine()) != null) {
templateContent += line;
}
br.close();
// 替换
templateContent = templateContent.replaceAll("###title###", 【替换的内容】);templateContent = templateContent.replaceAll("###htmlContent###", 【替换的内容】);
// 当前时间
String time = new SimpleDateFormat("yyyyMMdd").format(Calendar.getInstance().getTime());
// 生成文件的名称
String filename = String.valueOf(【文件名】 + "_" + time + "_" + (int) (Math.random() * (9999 - 1000 + 1) + 1000)) + ".html";
// 清空response
response.reset();
// 设置文件MIME类型
response.setContentType("text/html; charset=utf-8");
// 设置Content-Disposition
response.addHeader("Content-Disposition", "attachment;filename=" + new String(filename.getBytes("gb2312"), "ISO8859-1"));
// 读取文件
InputStream in = new ByteArrayInputStream(templateContent.getBytes("utf-8"));
OutputStream out = response.getOutputStream();
// 写文件
int b;
while ((b = in.read()) != -1) {
out.write(b);
}
in.close();
out.close();
