我使用Spring Boot和thymeleaf时遇到以下问题,我无法修复它。 在错误发生后立即运行Application类时发生错误。
我与百里香的布局是
主要\资源\模板
的HomeController
@Controller
public class HomeController {
@GetMapping("/")
public String root() {
return "page/home";
}
}
应用
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

答案 1 :(得分:6)
开始将classnotfoundexception: org.thymeleaf.spring5.ispringtemplateengine
升级到Spring Boot 1.5.14
时出现错误Spring Boot 2.0.4.
,在谷歌搜索时,该线程是最重要的结果。
我已经在使用Thymeleaf 3.0.7
。在Spring Boot升级之后,它不再起作用。经过一番尝试和错误之后,我注意到我没有将依赖项thymeleaf-spring4
升级到thymeleaf-spring5
,而在此期间,我将Thymeleaf升级到了3.0.9
。这对我来说很成功。

我的应用程序中出现了相同的错误,原因是我包括了依赖项
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>
没有
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
就我而言,我只是删除了我不需要的弹簧安全性并且可以工作。

您需要为Thymeleaf添加此依赖项:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
</dependency>
