使用freemark，导出word，

1：准备一份.doc的word文档作为模板

2：将.doc模板另存为.xml

3:格式化xml文件，将要输出的数据替换为对应的el表达式

如果是图片：不要折行和空格

4：导入freemark所需的jar包

5：获取要导出的数据

public static void exportMillCertificateWord(HttpServletRequest request, HttpServletResponse response, Map map,
String title, String ftlFile) throws IOException {
Template freemarkerTemplate = configuration.getTemplate(ftlFile);
File file = null;
InputStream fin = null;
ServletOutputStream out = null;
try {
// 生成Word文档
file = createDoc(map, freemarkerTemplate);
fin = new FileInputStream(file);
//设置编码及相应类型
response.setCharacterEncoding("utf-8");
response.setContentType("application/msword");
// 告诉浏览器下载的方式处理该文件名，防止乱码
String fileName = title;
response.setHeader("Content-Disposition","attachment;filename=".concat(String.valueOf(URLEncoder.encode(fileName, "UTF-8"))));
out = response.getOutputStream();
// 缓冲区
byte[] buffer = new byte[512];
int bytesToRead = -1;
// 将读入的Word文件的内容写入到浏览器
while ((bytesToRead = fin.read(buffer)) != -1) {
out.write(buffer, 0, bytesToRead);
}
} finally {
if (fin != null)
fin.close();
if (out != null)
out.close();
if (file != null)
file.delete(); // 删除临时文件
}

}

private static File createDoc(Map<?, ?> dataMap, Template template) {
String name = "model.doc";
File f = new File(name);
Template t = template;
try {
//指定编码：如果不指定模板，文件将打不开
Writer w = new OutputStreamWriter(new FileOutputStream(f), "utf-8");
t.process(dataMap, w);
w.close();
} catch (Exception ex) {
ex.printStackTrace();
throw new RuntimeException(ex);
}
return f;
}
