freemarker 入门
编写一个ftl文件如下
<%@ page language="java" pageEncoding="GBK" contentType="text/html;charset=GBK"%>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
</head>
<body>
The first test: ${persion.name}
</body>
</html>
写一个entity
public class User {
String name;
public User(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
用freemarker生成html文件
public class Test {
public static void main(String[] args) throws Exception{
//模板路径
String dir ="E:/e/";
Configuration cfg = new Configuration();
//加载freemarker模板文件
cfg.setDirectoryForTemplateLoading(new File(dir));
//设置对象包装器
cfg.setObjectWrapper(new DefaultObjectWrapper());
//设计异常处理器
cfg.setTemplateExceptionHandler(TemplateExceptionHandler.IGNORE_HANDLER);
//定义并设置数据
Map<String, User> data = new HashMap<String, User>();
data.put("persion", new User("zhang san"));
//获取指定模板文件
Template template = cfg.getTemplate(dir+"test.ftl");
//定义输入文件，默认生成在工程根目录
Writer out = new OutputStreamWriter(new FileOutputStream(dir+"test.html"),"GBK");
//最后开始生成
template.process(data, out);
System.out.println("successful");
}
}
运行以上代码将在E:/e/test.html,文件内容如下
<%@ page language="java" pageEncoding="GBK" contentType="text/html;charset=GBK"%>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
