你忘记了一个依赖关系。请添加

implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'

对你的依赖。

您可以在这里看到运行示例https://github.com/ozkanpakdil/spring-examples/tree/master/gradle-thymeleaf

我正在使用基于Git的Spring Cloud项目。在这个项目中，我指出了https://github.com/rseroter/pluralsight-spring-cloudconfig-wa-tolls。当我简单地启动URL:http://localhost:8888/actuator/s1rates/default或http://localhost:8888/s1rates/defaul

我通过cmd为Django设置网页。然而，我在访问127.0的索引页时遇到了问题。0.1:8001. 我试图更新URL。但是仍然有问题。浏览器页面错误：找不到页面（404）请求方法：获取请求URL:http://127.0.0.1:8001/index使用barry中定义的URLconf。Django尝试了以下URL模式，顺序如下：管理员/当前路径索引与这些路径中的任何一个都不匹配。

落后再循环视图

我的循环视图滚动太慢了。当我通过触摸Recyclerview开始滚动时，它会滞后，但当从上方的视图开始滚动时不会滞后。我还禁用了recyclerview上的嵌套滚动。这是我的布局: 这是一个滞后的视频。就像滚动跳过了一些布局。
