2、使用模板生成HTML代码

2.1 数据模型

public class User {PRivate String username;private String passWord;private Integer age;private String address;//省略setter和getter方法 }

2.2 FreeMarker模板

<!DOCTYPE html><html><head><meta charset="UTF-8"><title>用户信息</title><link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap.min.css" /></head><body style="font-family:'Courier New'"> <h3 class="text-center">这是用户${username}的信息页！</h3> <div class="col-md-6 column"> <table class="table table-bordered"> <tr> <th>用户名</th> <th>密码</th> <th>年龄</th> <th>地址</th> </tr> <tr> <td>${username}</td> <td>${password}</td> <td>${age}</td> <td>${address}</td> </tr> </table> </div></body></html>

2.3 使用FreeMarker生成HTML代码

/** * 使用模板生成HTML代码 */ public static void createHtmlFromModel() { FileWriter out = null; try { // 通过FreeMarker的Confuguration读取相应的模板文件 Configuration configuration = new Configuration(Configuration.VERSION_2_3_23); // 设置模板路径 configuration.setClassForTemplateLoading(CreateHtmlByFreemarker.class, "/static/ftl"); // 设置默认字体 configuration.setDefaultEncoding("utf-8"); // 获取模板 Template template = configuration.getTemplate("user.ftl"); //设置模型 User user = new User("tom", "hahahah", 28, "上海市"); //设置输出文件 File file = new File("e:/html/result.html"); if(!file.exists()) { file.createNewFile(); } //设置输出流 out = new FileWriter(file); //模板输出静态文件 template.process(user, out); } catch (TemplateNotFoundException e) { e.printStackTrace(); } catch (MalformedTemplateNameException e) { e.printStackTrace(); } catch (ParseException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (TemplateException e) { e.printStackTrace(); } finally { if(null != out) { try { out.close(); } catch (IOException e) { e.printStackTrace(); } } } }

3、使用String作为FreeMarker模板，生成HTML代码

3.1 数据模型使用2.1模型

3.2 模板使用2.2模板

3.3 使用FreeMarker生成HTML代码

/** * 把模板读入到String中，然后根据String构造FreeMarker模板 */ public static void createHtmlFromString() { BufferedInputStream in = null; FileWriter out = null; try { //模板文件 File file = new File("D:/EclipseLearnSpace/ResearchSpace/Html2Pdf/src/main/resources/static/html/user.html"); //构造输入流 in = new BufferedInputStream(new FileInputStream(file)); int len; byte[] bytes = new byte[1024]; //模板内容 StringBuilder content = new StringBuilder(); while((len = in.read(bytes)) != -1) { content.append(new String(bytes, 0, len, "utf-8")); } //构造Configuration Configuration configuration = new Configuration(Configuration.VERSION_2_3_23); //构造StringTemplateLoader StringTemplateLoader loader = new StringTemplateLoader(); //添加String模板 loader.putTemplate("test", content.toString()); //把StringTemplateLoader添加到Configuration中 configuration.setTemplateLoader(loader); //构造Model User user = new User("tom", "kkkkk", 29, "北京山东"); //获取模板 Template template = configuration.getTemplate("test"); //构造输出路 out = new FileWriter("e:/html/result.html"); //生成HTML template.process(user, out); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (TemplateException e) { e.printStackTrace(); } finally { if(null != in) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } if(null != out) { try { out.close(); } catch (IOException e) { e.printStackTrace(); } } } }

4、使用String模板，模板中使用List

4.1 数据模型

public class Classes { private String classId; // 班级ID private String className; // 班级名称 private List<User> users; public String getClassId() { return classId; } //省略settter和getter方法}

4.2 FreeMarker模板

<!DOCTYPE html><html><head><meta charset="UTF-8"><title>班级信息</title><link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.0/css/bootstrap.min.css" /><style type="text/css"> .table-align{ margin-left: 25%; }</style></head><body style="font-family:'Courier New'"> <h3 class="text-center">下面是班级ID【${classId}】，班级名称【${className}】的人员信息</h3> <div class="col-md-6 column table-align"> <table class="table"> <tr> <th>姓名</th> <th>密码</th> <th>年龄</th> <th>地址</th> </tr>  <#list users as user> <tr> <td>${user.username}</td> <td>${user.password}</td> <td>${user.age}</td> <td>${user.address}</td> </tr> </#list> </table> </div></body></html>

4.3 使用FreeMarker生成HTML代码

/** * 根据String模板生成HTML，模板中存在List循环 */ public static void createHtmlFromStringList() { BufferedInputStream in = null; FileWriter out = null; try { //模板文件 File file = new File("D:/EclipseLearnSpace/ResearchSpace/Html2Pdf/src/main/resources/static/html/class.html"); //构造输入流 in = new BufferedInputStream(new FileInputStream(file)); int len; byte[] bytes = new byte[1024]; //模板内容 StringBuilder content = new StringBuilder(); while((len = in.read(bytes)) != -1) { content.append(new String(bytes, 0, len, "utf-8")); } //构造Configuration Configuration configuration = new Configuration(Configuration.VERSION_2_3_23); //构造StringTemplateLoader StringTemplateLoader loader = new StringTemplateLoader(); //添加String模板 loader.putTemplate("test", content.toString()); //把StringTemplateLoader添加到Configuration中 configuration.setTemplateLoader(loader); //构造Model Classes classes = new Classes(); classes.setClassId("23"); classes.setClassName("实验一班"); List<User> users = new ArrayList<User>(); User user = new User("tom", "kkkkk", 29, "北京"); users.add(user); User user2 = new User("Jim", "hhhh", 22, "上海"); users.add(user2); User user3 = new User("Jerry", "aaaa", 25, "南京"); users.add(user3); classes.setUsers(users); //获取模板 Template template = configuration.getTemplate("test"); //构造输出路 out = new FileWriter("e:/html/result.html"); //生成HTML template.process(classes, out); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (TemplateException e) { e.printStackTrace(); } finally { if(null != in) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } if(null != out) { try { out.close(); } catch (IOException e) { e.printStackTrace(); } } } }
