利用freemaker实现合同管理

1.创建合同模板：

2.然后将word转换成XML：

    然后将里面的内容改成标准的${name}；

3.然后保存成 .ftl格式：

4.代码：

引入Jar：

		
			org.freemarker
			freemarker
			2.3.23
		

controller：

/***
	 * 导出Word材质单
	 * 
	 * @return
	 * @throws Exception
	 */
	@RequestMapping(value = "exportMillCertificate", method = RequestMethod.GET)
	@ResponseBody
	public void exportMillCertificate(HttpServletRequest request, HttpServletResponse response) throws Exception {
		// 获得数据，系统相关，就不展示了
		Map map = new HashMap();
		map.put("name", "老杨");
		map.put("desName", "老铁");
		WordUtils.exportMillCertificateWord(request, response, map);
	}

工具类utils：
