  • JFinal Web开发学习(九)后台添加前台显示博客

    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

    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: ${blog.author?if_exists}&nbsp;&nbsp;创建时间:${blog.create_date?if_exists}&nbsp;&nbsp;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.
