一、下载freemarker的jar包，到maven仓库下载
二、引入jar包，参考freemarker的手册写代码
1、Test.ftlh
<!DOCTYPE html>
<html>
<head>
<title>Welcome!</title>
</head>
<body>
<p>My name is ${username}, I'm ${age} years old, my birthday is ${date?string("yyyy-MM-dd")}</p>
</body>
</html>
2、com.freeMark.bean.User
package com.freeMark.bean; import java.util.Date; public class User { private String username; private int age; private Date date; public User(String username, int age, Date date) { this.username = username; this.age = age; this.date = date; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public Date getDate() { return date; } public void setDate(Date date) { this.date = date; } }
3、com.freeMark.FreemarkTest
package com.freeMark; import java.io.File; import java.io.OutputStreamWriter; import java.io.Writer; import java.util.Calendar; import java.util.GregorianCalendar; import com.freeMark.bean.User; import freemarker.template.Configuration; import freemarker.template.Template; import freemarker.template.TemplateExceptionHandler; public class FreemarkTest { public static void main(String[] args) { Calendar calendar = new GregorianCalendar(1994, 1, 18); User user = new User("youth", 22, calendar.getTime()); Configuration cfg = new Configuration(Configuration.VERSION_2_3_25); try { //设置模板的地址 cfg.setDirectoryForTemplateLoading(new File("src/ftl")); cfg.setDefaultEncoding("UTF-8"); //设置报错处理方式 cfg.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER); cfg.setLogTemplateExceptions(false); //取得模板 Template temp = cfg.getTemplate("Test.ftlh"); Writer out = new OutputStreamWriter(System.out); //设置模型数据 temp.process(user, out); } catch (Exception e) { e.printStackTrace(); } } }
三、输出结果
<!DOCTYPE html>
<html>
<head>
<title>Welcome!</title>
</head>
<body>
<p>My name is youth, I'm 22 years old, my birthday is 1994-02-18</p>
</body>
</html>
