標籤 jfinal web 開發學習後臺添加前臺顯示博客欄目 Java開源简体版

原文原文鏈接

效果：
發博客：javascript

顯示博客： php

後臺：使用hui-admin，文章編輯器是百度開源的ueditor
前臺：使用layui前端框架
1.寫控制器BlogController
controller包中css

package cn.pangpython.controller;

import com.jfinal.core.Controller;

import cn.pangpython.model.Blog;
import cn.pangpython.utils.DateUtils;


/**
 * @author pangPython
 *  博客模塊控制器
 *
 */
public class BlogController extends Controller{

    //訪問URL：/blog/
    public void index(){
    }

    //訪問URL：/blog/adminAddBlog
    //後臺添加博客文章
    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("添加失敗！");
        }

    }

    // 訪問URL：/blog/article/1
    //前臺根據傳入id顯示博客頁面
    public void article(){
            //獲取博客id
            int blog_id = getParaToInt(0);
            //查詢實例化blog對象
            Blog blog = Blog.dao.findById(blog_id);
            //設置模板攜帶參數
            setAttr("blog", blog);
            //渲染模板
            render("../admin/article.html");

    }

}

2.寫後臺html模板
後臺發佈文章頁面
WebRoot/admin/article-add.htmlhtml
