使用freemarker生成html、doc文件【原创】
语言：java
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 // 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 41 //文件名称 42 String m_fileName = result.getTbbh() + "_" + dateString + ".doc"; 43 // 44 String realPath=this.getClass().getClassLoader().getResource("/").getPath(); 45 //System.out.println(realPath); 46 int pos=realPath.indexOf("/WEB-INF"); 47 //System.out.println(pos); 48 realPath=realPath.substring(0, pos); 49 realPath=realPath+"/Upload/abnmTransSupDoc/"; 50 //System.out.println(realPath); 51 String filePath = realPath +m_fileName; 52 result.setAbdkFilepath("/tdlzJGXT/Upload/abnmTransSupDoc/"+m_fileName); 53 54 55 56 57 58 File outFile = new File(filePath); 59 Writer out = null; 60 try { 61 out = new BufferedWriter(new OutputStreamWriter( 62 new FileOutputStream(outFile), "utf-8")); 63 } catch (Exception e1) { 64 e1.printStackTrace(); 65 } 66 67 try { 68 t.process(result, out); 69 out.close(); 70 } catch (TemplateException e) { 71 e.printStackTrace(); 72 } catch (IOException e) { 73 e.printStackTrace(); 74 } 75 76 }
