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id
            int 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("../admin/article.html");

    }

}

2.写后台html模板
后台发布文章页面
WebRoot/admin/article-add.html
