FreeMarker几种不同方式的展现数据
FreeMarker几种不同方式的展现数据
http://blog.csdn.net/xumengxing/article/details/14476007
FreeMarker是一个模板引擎,一个基于模板生成文本输出的通用工具。 本文主要写了3种方法通过freemarker与java对象数据结合,将数据展现于前台页面。

公共类: User.java代码如下
- package com.hsinghsu.test.model;
- public class User
- {
- private int id;
- private String name;
- private int age;
- public String getName()
- {
- return name;
- }
- public void setName(String name)
- {
- this.name = name;
- }
- public int getId()
- {
- return id;
- }
- public void setId(int id)
- {
- this.id = id;
- }
- public int getAge()
- {
- return age;
- }
- public void setAge(int age)
- {
- this.age = age;
- }
- }
package com.hsinghsu.test.model;
public class User
{
    private int id;
    private String name;
    private int age;
    public String getName()
    {
        return name;
    }
    public void setName(String name)
    {
        this.name = name;
    }
    public int getId()
    {
        return id;
    }
    public void setId(int id)
    {
        this.id = id;
    }
    public int getAge()
    {
        return age;
    }
    public void setAge(int age)
    {
        this.age = age;
    }
    
}
UserDao.java 代码如下,用于生成模拟数据:
- package com.hsinghsu.test.dao;
- import java.util.ArrayList;
- import java.util.List;
- import com.hsinghsu.test.model.User;
- public class UserDao
- {
- public List<User> getUserList()
- {
- List<User> list = new ArrayList<User>();
- User user = null;
- for (int i = 0; i < 10; i++)
- {
- user = new User();
- user.setId(i);
- user.setName("name" + i);
- user.setAge(i + i);
- list.add(user);
- }
- return list;
- }
- }
package com.hsinghsu.test.dao;
import java.util.ArrayList;
import java.util.List;
import com.hsinghsu.test.model.User;
public class UserDao
{
    public List<User> getUserList()
    {
        List<User> list = new ArrayList<User>();
        User user = null;
        for (int i = 0; i < 10; i++)
        {
            user = new User();
            user.setId(i);
            user.setName("name" + i);
            user.setAge(i + i);
            list.add(user);
        }
        
        return list;
    }
}
1.使用struts配置文件直接将数据渲染到ftl中
UserActionFTL.java Action代码如下:
- package com.hsinghsu.test.action;
- import java.util.List;
- import com.hsinghsu.test.dao.UserDao;
- import com.hsinghsu.test.model.User;
- import com.opensymphony.xwork2.ActionSupport;
- /**
- * 通过struts配置文件直接渲染ftl
- * @author HsingHsu
- *
- */
- public class UserActionFTL extends ActionSupport
- {
- /**
- *
- */
- private static final long serialVersionUID = 1L;
- private List<User> uList;
- public String execute()
- {
- System.out.println("===begin");
- UserDao userDao = new UserDao();
- uList = userDao.getUserList();
- return SUCCESS;
- }
- public List<User> getuList()
- {
- return uList;
- }
- public void setuList(List<User> uList)
- {
- this.uList = uList;
- }
- }
package com.hsinghsu.test.action;
import java.util.List;
import com.hsinghsu.test.dao.UserDao;
import com.hsinghsu.test.model.User;
import com.opensymphony.xwork2.ActionSupport;
/**

 * @author HsingHsu

 */
public class UserActionFTL extends ActionSupport
{
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    private List<User> uList;
    public String execute()
    {
        System.out.println("===begin");
        UserDao userDao = new UserDao();
        uList = userDao.getUserList();
        return SUCCESS;
    }
    public List<User> getuList()
    {
        return uList;
    }
    public void setuList(List<User> uList)
    {
        this.uList = uList;
    }
}
struts.xml配置文件如下:
- <?xml version="1.0" encoding="UTF-8" ?>
- <!DOCTYPE struts PUBLIC
- "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
- "http://struts.apache.org/dtds/struts-2.0.dtd">

- <action name="userListFTL" class="com.hsinghsu.test.action.UserActionFTL">
- <result name="success" type="freemarker">/templates/userStrutsTemplate.ftl</result>
- </action>
- </package>
- </struts>
<?xml version="1.0" encoding="UTF-8" ?>
  <!DOCTYPE struts PUBLIC

	<package name="hsinghsu" extends="struts-default">

			<result name="success" type="freemarker">/templates/userStrutsTemplate.ftl</result>
		</action>
	</package>
</struts>
userStrutsTemplate.ftl文件配置如下:
- <table style="text-align:center;FONT-SIZE: 11pt; WIDTH: 600px; FONT-FAMILY: 宋体; BORDER-COLLAPSE: collapse" borderColor=#3399ff cellSpacing=0 cellPadding=0 align=center border=1>
- <tr>
- <td><b>id</b></td>
- <td><b>name</b></td>
- <td><b>age</b></td>
- </tr>
- <#list uList as user>
- <tr>
- <td>${user.id}</td>
- <td>${user.name}</td>
- <td>${user.age}</td>
- </tr>
- </#list>
- </table>
<table style="text-align:center;FONT-SIZE: 11pt; WIDTH: 600px; FONT-FAMILY: 宋体; BORDER-COLLAPSE: collapse" borderColor=#3399ff cellSpacing=0 cellPadding=0 align=center border=1>   
    <tr>   
        <td><b>id</b></td>   
        <td><b>name</b></td>  
        <td><b>age</b></td>    
    </tr>
    <#list uList as user>   
    <tr>   
        <td>${user.id}</td>   
        <td>${user.name}</td>
        <td>${user.age}</td>
    </tr>
	</#list>
</table>
2.通过生成html文件,返回该html的url
FTL2HtmlFlie.java 通过ftl生成html文件类代码如下:
