1、通过String来创建模版对象,并执行插值处理

执行后,控制台输出结果:

import freemarker.template.Template; 
import java.io.OutputStreamWriter; 
import java.io.StringReader; 
import java.util.HashMap; 
import java.util.Map; 
/** * Freemarker最简单的例子 * * @author leizhimin 11-11-17 上午10:32 */
 public class Test2 {  
public static void main(String[] args) 
throws Exception{   //创建一个模版对象   
Template t = new Template(null, new StringReader("用户名:${user};URL: ${url};姓名:  ${name}"), null);  
 //创建插值的Map   
Map map = new HashMap();   
map.put("user", "lavasoft");   
map.put("url", "http://www.baidu.com/");  
 map.put("name", "百度");  
 //执行插值,并输出到指定的输出流中  
 t.process(map, new OutputStreamWriter(System.out));  } }
Copy after login
用户名:lavasoft;URL:    <a href="http://www.baidu.com/;">http://www.baidu.com/;
</a>姓名:  百度 Process finished with exit code 0<br>
Copy after login

2、通过文件来创建模版对象,并执行插值操作

import freemarker.template.Configuration;
 import freemarker.template.Template; 
import java.io.File; 
import java.io.OutputStreamWriter; 
import java.util.HashMap; 
import java.util.Map; 
/** * Freemarker最简单的例子 * * @author leizhimin 11-11-14 下午2:44 */
public class Test { private Configuration cfg; 
//模版配置对象 public void init() throws Exception { 
//初始化FreeMarker配置 //创建一个Configuration实例 cfg = new Configuration();
 //设置FreeMarker的模版文件夹位置 
cfg.setDirectoryForTemplateLoading(new File("G:\\testprojects\\freemarkertest\\src")); } 
public void process() throws Exception { //构造填充数据的Map Map map = new HashMap(); 
 map.put("user", "lavasoft"); map.put("url", "http://www.baidu.com/"); 
 map.put("name", "百度"); //创建模版对象 Template t = cfg.getTemplate("test.ftl"); 
//在模版上执行插值操作,并输出到制定的输出流中 t.process(map, new OutputStreamWriter(System.out)); }
 public static void main(String[] args) 
throws Exception { Test hf = new Test(); hf.init(); hf.process(); } }
Copy after login

创建模版文件test.ftl

<html> <head> <title>Welcome!</title> </head>
<body> <h1>Welcome ${user}!</h1> <p>Our latest product: <a href="${url}">${name}</a>! </body>
 </html> 尊敬的用户你好: 用户名:${user}; URL: ${url}; 姓名:  ${name}
Copy after login

执行后,控制台输出结果如下:

<html> <head> <title>Welcome!</title> </head>
 <body> <h1>Welcome lavasoft!</h1> <p>Our latest product: <a href="http://www.baidu.com/">百度</a>! </body> </html>
尊敬的用户你好: 用户名:lavasoft; URL: http://www.baidu.com/; 姓名:  百度 Process finished with exit code 0
Copy after login
