<html lang="zh-Hans" xmlns:th="http://www.thymeleaf.org">
<div th:each="article,ArticleList:${articleList}"></div>
解释：如果article.getArticleCover得到的值不是‘‘ 则该div应用cover这个class属性否则noimg
<div th:class="${article.getArticleCover()!=‘‘}?cover:noimg">
<div class="stat" th:text="${#dates.format(article.getUpdateDate(), ‘yyyy-MM-dd HH:mm:ss‘)}">
<div class="article" th:each="article,ArticleBean:${articleList}">
<a th:href="‘http://localhost:8080/p/‘+${article.getArticleId()}+‘.html‘" target="_blank">
<div class="row">
<div class="title" th:text="${article.getArticleTitle()}">
</div>
<div th:class="${article.getArticleCover()!=‘‘}?cover:noimg">
<img th:src="${article.getArticleCover()}" th:class="${article.getArticleCover()!=‘‘}?img:noimg"/>
</div>
<div class="sketch" th:text="${article.getArticleSketch()}">
