【Thymeleaf】获取Thymeleaf的当前日期

直接使用Thymeleaf获取当前时间，并进行格式化

1. 添加pom文件

  
     org.springframework.boot
      spring-boot-starter-thymeleaf
  
  
      org.thymeleaf.extras
      thymeleaf-extras-java8time
  

2. Thymeleaf格式如下

th:text="${#dates.format(#dates.createNow(), 'yyyy-MM-dd HH:mm')}"

3. 实例：

    
    



巡检时间：, 巡检ES索引模板shard个数不合理处理详情如下!

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：

    org.thymeleaf.extras
    thymeleaf-extras-java8time
