前言
直接使用Thymeleaf获取当前时间，并进行格式化
实施
- 添加pom文件
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-java8time</artifactId>
</dependency>
- Thymeleaf格式如下
th:text="${#dates.format(#dates.createNow(), 'yyyy-MM-dd HH:mm')}"
- 实例：
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>巡检ES索引模板shard个数不合理</title>
</head>
<body>
<h3>巡检时间：<span style="font-size: 25px" th:text="${#dates.format(#dates.createNow(), 'yyyy-MM-dd HH:mm')}"></span>, 巡检ES索引模板shard个数不合理处理详情如下!</h3>
<pre>------------------------------</pre>
<table style="width:100%;" cellpadding="2" cellspacing="0" border="1" bordercolor="#337FE5">
<tr>
<th>索引模式名称:</th>
<th>修改索引模板结果</th>
<th>修改索引模板状态</th>
</tr>
<tr th:each="info : ${ajaxResultList}" >
<td th:text="${info.data}"></td>
<td th:text="${info.msg}"></td>
<td th:text="${info.code}"></td>
</tr>
</table>
</body>
</html>
问题一：
报错信息：

解决方案：
查找相关资料，发现thymeleaf对于此类报错，增加了一个增强包，maven工程中需要在pom中引入如下包：
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-java8time</artifactId>
</dependency>
