错误记录 - This may be the result of an unspecified view, due to default view name generation

• 问题描述
  初学尝试使用springboot 无法跳转页面 ，报错500
• 异常信息:

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.)

• 问题原因
  未引入Thymeleaf模板依赖,

• 解决方案

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

`

但我在加入依赖后仍无法引入Thymeleaf包，发现libraries仍未引入包，reimport 无效，后指定thymeleaf版本成功引入

 <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputeEncoding>UTF-8</project.reporting.outputeEncoding>
        <java.version>1.8</java.version>
        <thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>
        <thyeleaf-layout-dialect.version>2.1.1</thyeleaf-layout-dialect.version>
    </properties>
