导出html(带自选地址)

1.创建需要导出的html模板，我创的模板是template.html，放到项目WEB-INF/content下面。

	###content###

2.工具类

public class JspToHtml {
	
     /**
            * 根据本地模板生成静态页面
      * @param JspFile    jsp路经
      * @param HtmlFile html路经
      * @return
      */
        public static boolean JspToHtmlFile(String filePath, String title,String context,String fileName) {
    		HttpServletResponse response = ServletActionContext.getResponse();
    		HttpServletRequest request = ServletActionContext.getRequest();
    		
            String str = "";
            long beginDate = (new Date()).getTime();
            try {
                    String tempStr = "";
                    FileInputStream is = new FileInputStream(filePath);//读取模块文件
                    BufferedReader br = new BufferedReader(new InputStreamReader(is));
                    while ((tempStr = br.readLine()) != null)
                    str = str + tempStr ;
                    is.close();
            } catch (IOException e) {
                    e.printStackTrace();
                    return false;
            }
            
    		//新建文件
    		OutputStream out = null;
            try {
               
                str = str.replaceAll("###title###",title);
                str = str.replaceAll("###content###",context);//替换掉模块中相应的地方
                
				//否则，直接写到输出流中
				out = response.getOutputStream();
				BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out));
				fileName = fileName+".html";
				response.setContentType("application/x-msdownload");
				final String userAgent = request.getHeader("USER-AGENT");  //获取浏览器的代理
				//下面主要是让文件名适应不同浏览器的编码格式
				String finalFileName = null;
				if(StringUtils.contains(userAgent, "MSIE")) {
					finalFileName = URLEncoder.encode(fileName,"UTF8");
				}else if(StringUtils.contains(userAgent, "Mozilla")){//google,火狐浏览器
					finalFileName = new String(fileName.getBytes(), "ISO8859-1");
				}else{
					finalFileName = URLEncoder.encode(fileName,"UTF8");//其他浏览器
				}
				response.setHeader("Content-Disposition", "attachment; filename=\"" + 
						finalFileName + "\"");
                System.out.println("共用时：" + ((new Date()).getTime() - beginDate) + "ms");

                writer.write(str);
                writer.close();
            } catch (IOException e) {
                    e.printStackTrace();
                    return false;
            } finally {  
    			try {
    				out.close();
    			} catch (IOException e) {
    				e.printStackTrace();
    			}
    		} 
            return true;
        }
}

3.调用

//导出html
//获得项目的根路径
String path = request.getSession().getServletContext().getRealPath("/");
//将根路径与模板地址拼接，从而才能找到html模板
String url = path+"WEB-INF\\content\\template.html";//模板文件根地址
//标题，对应模板中###title###
String title = "标题";
//内容，对应模板中###context###
String context = "内容";
//导出的html的名字+时间戳
String fileName = "名字"+System.currentTimeMillis();
JspToHtml c = new JspToHtml();
c.JspToHtmlFile(url, title, context, fileName);

4.完成
