篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了editormd实现文章详情页面预览相关的知识，希望对你有一定的参考价值。
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/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/jquery.flowchart.min.js"></script>
<script src="plugins/editormd/editormd.js"></script>前端的jsp页面：
