本文主要是介绍JFinal Web开发学习(九)后台添加前台显示博客,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
代码:
https://code.csdn.net/u012995856/jfinaltest/tree/master
效果:
发博客:
显示博客:
后台:使用hui-admin,文章编辑器是百度开源的ueditor
前台:使用layui前端框架
1.写控制器BlogController
controller包中
package cn.pangpython.controller;import com.jfinal.core.Controller;import cn.pangpython.model.Blog;
import cn.pangpython.utils.DateUtils;/*** @author pangPython* 博客模块控制器**/
public class BlogController extends Controller{//访问URL:/blog/public void index(){}//访问URL:/blog/adminAddBlog//后台添加博客文章public void adminAddBlog(){Blog blog = getModel(Blog.class);blog.setTitle(getPara("blog.title"));blog.setAuthor(getPara("blog.author"));blog.setContent(getPara("blog.content"));blog.setCreateDate(DateUtils.getNowTime());blog.setUpdateDate(DateUtils.getNowTime());if(blog.save()){renderText("添加成功!");}else{renderText("添加失败!");}}// 访问URL:/blog/article/1//前台根据传入id显示博客页面public void article(){//获取博客idint blog_id = getParaToInt(0);//查询实例化blog对象Blog blog = Blog.dao.findById(blog_id);//设置模板携带参数setAttr("blog", blog);//渲染模板render("article.html");}}
2.写后台html模板
后台发布文章页面
WebRoot/admin/article-add.html

</script>
<!--/请在上方写此页面业务相关的脚本-->
</body>
</html>
前台显示博客页面
WebRoot/blog/article.html
<!doctype html>
<html>
<head><meta charset="utf-8"><title>${blog.title?if_exists}</title><meta name="renderer" content="webkit"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"><link rel="stylesheet" href="/static/layui/css/layui.css" media="all">
</head>
<body><ul class="layui-nav"><li class="layui-nav-item"><a href="">Logo</a></li><li class="layui-nav-item "><a href="">首页</a></li><li class="layui-nav-item layui-this"><a href="">博客</a></li><li class="layui-nav-item"><a href="">关于我们</a></li>
</ul><fieldset class="layui-elem-field layui-field-title" style="margin-top: 50px;"><legend>BLOG</legend>
</fieldset><br>
<div class="layui-main"><fieldset class="layui-elem-field"><legend>${blog.title?if_exists}</legend>作者: ${blog.author?if_exists} 创建时间:${blog.create_date?if_exists} 更新时间:${blog.update_date?if_exists}<hr><blockquote class="layui-elem-quote">${blog.content?if_exists}</blockquote></fieldset></div><script src="/static/layui/layui.js"></script><script>
//配置自己的js加载路径
layui.config({base:'/static/js/modules/'}).use('index');</script></body>
</html>
3.配置路由
routers包中
FrontRouters.java
config方法中添加
add("/blog",BlogController.class);
4.简单测试
添加文章:
localhost/admin/index
博客管理->文章管理->添加资讯
注:此处添加文章的方法未做权限控制
查看文章:
localhost/blog/article/1
注:此处article后边是博客id,根据自己添加的博客的id进行查看,此处未做异常处理,试图访问不存在的id后台会报错.
