功能：使用freemarker生成html、doc
1、生成html
1 public void updateuseFreemarker2html(String abdkId) { 2 // 要填入模本的数据文件 3 Session session = sessionFactory.getCurrentSession(); 4 String hql = "from AbnmDktranssupervision as abnmDktranssupervision "; 5 AbnmDktranssupervision result = null; 6 try { 7 // 根据id用hql语言获取一个对象的数据 8 result = (AbnmDktranssupervision) session.get( 9 AbnmDktranssupervision.class, Integer.parseInt(abdkId));10 } catch (Exception e) {11 e.printStackTrace();12 }13 14 15 16 // 设置模本装置方法和路径,FreeMarker支持多种模板装载方法。可以重servlet，classpath，数据库装载，17 // 这里我们的模板是放在cn.edu.bnu.land.common包下面18 configuration = new Configuration();19 configuration.setEncoding(Locale.CHINA, "utf-8"); 21 configuration.setClassForTemplateLoading(this.getClass(),22 "/cn/edu/bnu/land/common");23 Template t = null;24 25 try {26 // freemarker2html.ftl为要装载的html模板27 t = configuration.getTemplate("freemarker2html.ftl");28 t.setEncoding("utf-8");29 } catch (IOException e) {30 e.printStackTrace();31 }32 33 34 // 输出文档路径及名称35 Calendar ca = Calendar.getInstance();36 Date date = ca.getTime();37 java.text.DateFormat format2 = new java.text.SimpleDateFormat(38 "yyyyMMddhhmmss");39 String dateString = format2.format(date);40 //文件名称41 String m_fileName = result.getTbbh() + "_" + dateString + ".html";42 //43 String realPath=this.getClass().getClassLoader().getResource("/").getPath();44 System.out.println(realPath);45 int pos=realPath.indexOf("/WEB-INF");46 System.out.println(pos);47 realPath=realPath.substring(0, pos);48 realPath=realPath+"/Upload/abnmTransSupHtml/"; 49 System.out.println(realPath);50 String filePath = realPath +m_fileName;51 result.setAbdkFilepath("/tdlzJGXT/Upload/abnmTransSupHtml/"+m_fileName);53 54 55 File outFile = new File(filePath);56 Writer out = null;57 try {58 out = new BufferedWriter(new OutputStreamWriter(59 new FileOutputStream(outFile), "utf-8"));60 } catch (Exception e1) {61 e1.printStackTrace();62 }63 64 try {65 t.process(result, out);66 out.close();67 } catch (TemplateException e) {68 e.printStackTrace();69 } catch (IOException e) {70 e.printStackTrace();71 } 72 }73 74 }
