SpringBoot - 使用Thymeleaf ---- Controller返回view报错

报错信息

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

Controller代码

package com.flyange.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {

    @RequestMapping("/test")
    public String test(Model model){
        model.addAttribute("msg","Hello,Thymeleaf!");
        return "test";
    }
}

html代码

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<div th:text="${msg}">test</div>
</body>
</html>

解决方法

pom.xml中添加 Thymeleaf starter

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

<!-- Thymeleaf 引入，
    如果Springboot版本是 1.x 就用2.x的
    如果Springboot版本是 2.x 就用3.x的
    -->
<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf</artifactId>
</dependency>
<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-java8time</artifactId>
</dependency>
