editormd实现文章详情页面预览

时间：2022-01-30 18:17:33

继之前博客写了editmd.js（国内开源的一款前端Markdown框架）实现的写文章功能之后，本博客介绍使用editormd实现文章预览功能，之前博客链接：https://blog.csdn.net/u014427391/article/details/86378811

要从上篇博客介绍的将Markdown语法的语句存储在数据库之后，读取出来，然后调用editormd的一些js脚本就可以实现

主要参考editormd提供的examples文件夹下面的html-preview-markdown-to-html.html

后台实现：

采用jpa实现

package net.myblog.repository;

import java.util.Date;

import java.util.List;

import net.myblog.entity.Article;

import org.springframework.data.domain.Page;

import org.springframework.data.domain.PageRequest;

import org.springframework.data.domain.Pageable;

import org.springframework.data.jpa.repository.Query;

import org.springframework.data.repository.PagingAndSortingRepository;

import org.springframework.data.repository.query.Param;

public interface ArticleRepository extends PagingAndSortingRepository<Article,Integer>{

	/**

	 * 获取文章详情信息

	 * @param articleId

	 * @return

	 */

	@Query("from Article a where a.articleId=:articleId")

	public Article getArticleInfo(@Param("articleId")int articleId);

Service类：

/**

	 * 获取文章详情信息

	 * @param articleId

	 * @return

	 */

	public Article getArticleInfo(int articleId) {

		return articleRepository.getArticleInfo(articleId);

	}

Controller类

/**

     * 博客详情页面

     * @return

     */

    @RequestMapping(value = "/details")

    public ModelAndView details(@RequestParam("articleId")String articleId) {

        ModelAndView mv = this.getModelAndView();

        Article article = articleService.getArticleInfo(Integer.parseInt(articleId));

        mv.addObject("article",article);

        mv.setViewName("myblog/article/article_details");

        return mv;

    }

jsp页面：

实现主要依赖于editormd.js提供的第三方库脚本:

<script src="plugins/editormd/lib/marked.min.js"></script>

<script src="plugins/editormd/lib/prettify.min.js"></script>

<script src="plugins/editormd/lib/raphael.min.js"></script>

<script src="plugins/editormd/lib/underscore.min.js"></script>

<script src="plugins/editormd/lib/sequence-diagram.min.js"></script>

<script src="plugins/editormd/lib/flowchart.min.js"></script>

<script src="plugins/editormd/lib/jquery.flowchart.min.js"></script>

<script src="plugins/editormd/editormd.js"></script>

前端的jsp页面：

<%@ page language="java" contentType="text/html; charset=UTF-8"

		 pageEncoding="UTF-8"%>

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>

<%

	String path = request.getContextPath();

	String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<!DOCTYPE html>

<html lang="zh">

	<base href="<%=basePath %>">
