SpringBoot项目使用视图解析器解决Circular view path 问题

1、我的controller
@Controller
public class LoginController {
@RequestMapping("/login")
public String login() {

return "login";
}

}
2、我的html页面login.html

<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>

login.html文件放在templates文件夹下，我的本意是想访问localhost:8080/login然后跳转到login.html界面，但是报错了，错误如下：

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、解决方法，在pom文件中添加如下依赖

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