freemarker获取封装类中对象的属性
1、设计思路
（1）封装学生类
（2）创建数据模型
（3）新建student.ftl
（4）运行Junit测试文件，生成HTML文件

2、封装学生类
Student.java：
/** * @Title:Student.java * @Package:com.you.freemarker.model * @Description:学生类 * @author:Youhaidong(游海东) * @date:2014-5-26 下午11:41:05 * @version V1.0 */package com.you.freemarker.model;import java.io.Serializable;import java.util.Date;/** * 类功能说明 * 类修改者 修改日期 * 修改说明 * <p>Title:Student.java</p> * <p>Description:游海东个人开发</p> * <p>Copyright:Copyright(c)2013</p> * @author:游海东 * @date:2014-5-26 下午11:41:05 * @version V1.0 */public class Student implements Serializable { /** * @Fields serialVersionUID:序列化 */ private static final long serialVersionUID = 1L; /** * 学生姓名 */ private String studentName; /** * 学生性别 */ private String studentSex; /** * 学生年龄 */ private int studentAge; /** * 学生生日 */ private Date studentBirthday; /** * 学生地址 */ private String studentAddr; /** * QQ */ private long studentQQ; /** * @return the studentName */ public String getStudentName() { return studentName; } /** * @param studentName the studentName to set */ public void setStudentName(String studentName) { this.studentName = studentName; } /** * @return the studentSex */ public String getStudentSex() { return studentSex; } /** * @param studentSex the studentSex to set */ public void setStudentSex(String studentSex) { this.studentSex = studentSex; } /** * @return the studentAge */ public int getStudentAge() { return studentAge; } /** * @param studentAge the studentAge to set */ public void setStudentAge(int studentAge) { this.studentAge = studentAge; } /** * @return the studentBirthday */ public Date getStudentBirthday() { return studentBirthday; } /** * @param studentBirthday the studentBirthday to set */ public void setStudentBirthday(Date studentBirthday) { this.studentBirthday = studentBirthday; } /** * @return the studentAddr */ public String getStudentAddr() { return studentAddr; } /** * @param studentAddr the studentAddr to set */ public void setStudentAddr(String studentAddr) { this.studentAddr = studentAddr; } /** * @return the studentQQ */ public long getStudentQQ() { return studentQQ; } /** * @param studentQQ the studentQQ to set */ public void setStudentQQ(long studentQQ) { this.studentQQ = studentQQ; } /** * <p>Title:</p> * <p>Description:无参构造函数</p> */ public Student() { super(); } /** * <p>Title:</p> * <p>Description:有参构造函数</p> * @param studentName * @param studentSex * @param studentAge * @param studentBirthday * @param studentAddr * @param studentQQ */ public Student(String studentName, String studentSex, int studentAge, Date studentBirthday, String studentAddr, long studentQQ) { super(); this.studentName = studentName; this.studentSex = studentSex; this.studentAge = studentAge; this.studentBirthday = studentBirthday; this.studentAddr = studentAddr; this.studentQQ = studentQQ; }}3、创建数据模型
Map<String,Object> root = null; /** * * @Title:testStudent * @Description: * @param: * @return: void * @throws */ @Test public void testStudent() { //创建数据模型 root = new HashMap<String,Object>(); root.put("student", new Student("张三丰","男",34,new Date(1988-12-12),"湖北省武汉市武昌洪山区",78451214)); student("student.ftl"); studentFile("student.ftl","student.html"); } /** * * @Title:student * @Description: * @param:@param name * @return: void * @throws */ private void student(String name) { ft.printFtl(name,root); } /** * * @Title:studentFile * @Description: * @param:@param name * @param:@param fileName * @return: void * @throws */ private void studentFile(String name,String fileName) { ft.printFile(name, root, fileName); }4、新建student.ftl
student.ftl：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <title>学生信息</title> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="this is my page"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> 姓名：${student.studentName} 性别：${student.studentSex} 年龄：${student.studentAge} 生日：${(student.studentBirthday)?string("yyyy-MM-dd")} 地址：${student.studentAddr} QQ：${student.studentQQ} </body></html>5、运行Junit测试文件，生成HTML文件
6、控制台输出结果
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <title>学生信息</title> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="this is my page"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> 姓名：张三丰 性别：男 年龄：34 生日：1970-01-01 地址：湖北省武汉市武昌洪山区 QQ：78,451,214 </body></html>给我老师的人工智能教程打call！http://blog.csdn.net/jiangjunshow
