1.首先从官方下载freemarker的包，下载地址：http://freemarker.sourceforge.net/freemarkerdownload.html
2.把包lib/freemarker.jar拷贝到项目中
3.新建模板文件WEB-INF/templates/test.ftl，内容如下：
Hello,${name}!
4.新建一个操作类Class1.java，内容如下：
package com.abc.web;
import java.io.Writer;
import java.util.HashMap;
import java.util.Map; import javax.servlet.jsp.PageContext; import freemarker.template.Configuration;
import freemarker.template.Template; publicclass Class1 {
publicvoid execute(PageContext pageContext) throws Exception
{
Configuration cfg =new Configuration();
cfg.setServletContextForTemplateLoading(pageContext.getServletContext(), "WEB-INF/templates");
root.put("name", "Tom");
import java.util.HashMap;
import java.util.Map; import javax.servlet.jsp.PageContext; import freemarker.template.Configuration;
import freemarker.template.Template; publicclass Class1 {
publicvoid execute(PageContext pageContext) throws Exception
{
Configuration cfg =new Configuration();
cfg.setServletContextForTemplateLoading(pageContext.getServletContext(), "WEB-INF/templates");
Map root
=new HashMap();root.put("name", "Tom");
Template t
= cfg.getTemplate("test.ftl");Writer out
= pageContext.getResponse().getWriter();t.process(root, out);
}
}
5.新建一个jsp页面test1.jsp，内容如下：
<%@ page language="java" contentType="text/html; charset=GB2312"
pageEncoding="GB2312"%>
<%@ page import="com.abc.web.Class1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB2312">
<title>Insert title here</title>
</head>
<body>
<%
Class1 c1 =new Class1();
c1.execute(pageContext);
%>
</body>
</html>
pageEncoding="GB2312"%>
<%@ page import="com.abc.web.Class1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB2312">
<title>Insert title here</title>
</head>
<body>
<%
Class1 c1 =new Class1();
c1.execute(pageContext);
