freemarker获取封装类中对象的属性（六）

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>
