错误产生环境

SpringBoot项目 整合thymeleaf 时产生

错误描述

javax.servlet.ServletException: Circular view path [index]: would dispatch back to the current handler URL [/index] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

错误原因

• 控制层代码
  
  templates 目录下也有index.html文件

为什么我访问网站根 目录时产生错误呢

原因竟然是我thymeleaf 的依赖导入错误，导致了异常的产生

解决办法

导入正确的依赖即可

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
