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
