java根据提供word模板导出word文档_javal根据浏览器模板导出word

涉及主要jar包为 freemarker-2.3.10.jar，servlet-api-2.4.jar。

（1）首先修改 word模板如下形式，把需要查询写入word的值用${}形式封装

（2）把 word改为ftl格式

首先word另存为选择xml

然后重命名直接将XML文件修改后缀名为ftl文件

（3）关键代码

  public void agentWordDownload(String agentCode, HttpServletRequest request,
        HttpServletResponse response) {
        //首先把word生成保存在某一地址
        boolean Wordsave = this.Wordsave(agentCode, request, response);
 
        //如果生成成功则可以下载
        if (Wordsave) {
            String url = AgentManageServiceSpringImpl.class.getResource("")
                                                           .toString();

            //获取项目路径
            url = "/" + url.substring(6, url.indexOf("WEB-INF")) +
                "downloadFiles" + "/" + "agentInfo" + "/";
