package freemarker;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.HashMap;
import java.util.Map;
import freemarker.template.Configuration;
import freemarker.template.Template;
public classTest2{
 private Configurationcfg;
 public ConfigurationgetCfg(){
  return cfg;
 }
 public void init()throws Exception{
  cfg=new Configuration();
  cfg.setDirectoryForTemplateLoading(newFile("bin/freemaker"));
 }
 public static void main(String[]args)throws Exception{
  Test2 obj=new Test2();
  obj.init();
  Map root=new HashMap();
  root.put("user","java2000.net");
  Map latestProduct=new HashMap();
  latestProduct.put("url","http://www.java2000.net");
  latestProduct.put("name","Java世纪网");
  root.put("latestProduct",latestProduct);
  Templatet=obj.getCfg().getTemplate("Test2.ftl");
  Writer out=new OutputStreamWriter(new FileOutputStream("Test2.html"),"GBK");
  t.process(root,out);
  System.out.println("Successfull................");
 }
}


模板
<html>
<head>
 <title>Welcome!</title>
</head>
<body>
 <h1>Welcome${user}!</h1>
 <p>Ourlatestproduct:
 <a href="${latestProduct.url}">${latestProduct.name}</a>!
</body>
</html>

运行结果
<html>
<head>
 <title>Welcome!</title>
</head>
<body>
 <h1>Welcomejava2000.net!</h1>
 <p>Ourlatestproduct:
 <a href="http://www.java2000.net">Java世纪网</a>!
</body>
</html>


分析:

  数据结构为

(root)
|
+- user = "java2000.net"
|
+- latestProduct
|
+- url = "http://www.java2000.net"
|
+- name = "Java世纪网"

  我们使用嵌套的Map给其传递参数
