/**
 * 首页
 *
 * @return
 */
@RequestMapping("/")
public ModelAndView index() {
    PageBean pageBean = new PageBean(1, 20);
    System.out.println("首页");
    ModelAndView mav = new ModelAndView();
    Page<Article> articlePage = articleService.page(new Page<>(pageBean.getPage(), pageBean.getPageSize()), new QueryWrapper<Article>().orderByDesc("publish_date"));
    mav.addObject("articleList", articlePage.getRecords());
    mav.setViewName("index");
    return mav;
}

网页上 显示数据：

<div class="post_list">
    <div class="post_item" th:each="article,status:${articleList}">
        <div class="post_item_text">
            <a class="post_item_title" th:href="'/article/'+${article.id}" target="_blank" th:text="${article.title}"></a>
            <div class="post_item_summary">
                <a th:href="'/article/'+${article.id}" target="_blank"><img class="avatar" th:src="'/randomImages/'+${(status.index)%10+1}+'.png'"/></a>
                <p th:text="${article.summary}"></p>
            </div>
        </div>
        <div class="publishDate" th:text="${#dates.format(article.publishDate, 'yyyy-MM-dd HH:mm:ss')}"></div>
    </div>
</div>

帖子随机小图标，映射路径：

randomImagesFilePath: D:\\randomImages\\

@Value("${randomImagesFilePath}")
private String randomImagesFilePath;

registry.addResourceHandler("/randomImages/**").addResourceLocations("file:"+randomImagesFilePath);  // 随机头像图片映射

分页实现：

mav.addObject("pageCode", PageUtil.genPagination("/article/list", articlePage.getTotal(), 1, pageBean.getPageSize(), ""));

<div class="pageCode" th:utext="${pageCode}"></div>
