FreeMarker 真实案例使用

FreeMarker 真实案例应用
定义模板

这个模板很简单，就是定义了一个显示文章的指今，然在的显示最新文章和热门文章的时候调用即可

模板文件源代码：

<#macro showNewArticles articles>    <#list articles as article>        <li>        ${article_index+1}.        <a target="_blank" href="/article/${article.id }">${article.title }</a>    </li>    </#list></#macro><%@ page language="java" contentType="text/html; charset=UTF-8"   pageEncoding="UTF-8"%><link rel="stylesheet" type="text/css" href="/resources/css/foot.css" /><div id="footer_area">    <div id="footer_area_content">    <div name="code">package com.naxsu.service;  import java.util.HashMap;import java.util.List;import java.util.Map;  import javax.annotation.Resource;  import org.springframework.stereotype.Service;  import com.naxsu.entity.Article;import com.naxsu.utils.FreemarkerUtil;@Service("freemarkerService")public class FreeMarkerService {    @Resource(name="articleService")    private ArticleService articleservice;                public void getFootPage() {    Map<String,Object> root = new HashMap<String,Object>();    List<Article> newDESCArticles = articleservice.getNewDESCArticle();    List<Article> viewCountDescArticles = articleservice.getViewCountDESCArticle();    root.put("newDESCArticles", newDESCArticles);    root.put("viewCountDescArticles", viewCountDescArticles);              String path =  this.getClass().getProtectionDomain()                           .getCodeSource().getLocation().getPath();    path = path.substring(0,path.indexOf("/WEB-INF"));    FreemarkerUtil.getInstance().fprint("foot.ftl", root,                      path+"/WEB-INF/jsp/template/foot.jsp");    }      }

用spring aop实现切面拦截文章的增删改的服务

在增删改文章的时候都会调用freemarkerService，从而生成相应的jsp。FreeMarker与SpringMVC整合在这里不做多说，请看相关的文章。

源代码如下：

<aop:config>    <aop:aspect ref="freemarkerService">    <aop:pointcut id="createFootTemplate"        expression="execution(* com.naxsu.service.ArticleService.insert*(..))||        execution(* com.naxsu.service.ArticleService.update*(..))||        execution(* com.naxsu.service.ArticleService.delete*(..))"/>    <aop:after method="getFootPage" arg-names="id" pointcut-ref="createFootTemplate"/>    </aop:aspect></aop:config>

jsp的嵌入

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ include file="../template/foot.jsp"%>
