1、我的controller

@Controller
public class LoginController {
	@RequestMapping("/login")
	public String login() {

		return "login";
	}

}

2.私のhtmlページlogin.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>登录</title>
</head>
<body>
<h1>欢迎登录!</h1>
<form >
    <input type="text" name="username" />   <br />
    <input type="password"name="password"/> <br />
    <input type="submit" value="提交" />
</form>
</body>
</html>

login.htmlファイルはtemplatesフォルダーに配置されます。当初の意図はlocalhost：8080 / loginにアクセスして、login.htmlインターフェイスにジャンプすることでしたが、エラーが報告されました。エラーは次のとおりです。

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

3.解決策、pomファイルに次の依存関係を追加します

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