FreeMarker小例子一枚

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;

public class Class1 {
public void 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);
}
}

复制代码

 

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 >

复制代码

 

页面的显示效果为：
