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 }

2、生成doc

 1     // ues freemarker+xml to doc 2     public void updateuseFreemarker2doc(String abdkId) { 3         // 要填入模本的数据文件 4         Session session = sessionFactory.getCurrentSession(); 5         String hql = "from AbnmDktranssupervision as abnmDktranssupervision "; 6         AbnmDktranssupervision result = null; 7         try { 8             // System.out.println(hql); 9             result = (AbnmDktranssupervision) session.get(10                     AbnmDktranssupervision.class, Integer.parseInt(abdkId));11         } catch (Exception e) {12             e.printStackTrace();13         }14         15         16         17         // 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,18         // 这里我们的模板是放在com.havenliu.document.template包下面19         configuration = new Configuration();20         configuration.setDefaultEncoding("utf-8");21         configuration.setClassForTemplateLoading(this.getClass(),22                 "/cn/edu/bnu/land/common");23         Template t = null;24 25         try {26             // test.ftl为要装载的模板27             t = configuration.getTemplate("freemarker2doc.ftl");28             t.setEncoding("utf-8");29         } catch (IOException e) {30             e.printStackTrace();31         }32         33 34         //
