I have my login.html file in the folder "/main/resource/templates" and i have configured the internal view resolver as follows

 @Bean
public InternalResourceViewResolver internalResourceViewResolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/main/resource/templates");
    resolver.setSuffix(".html");
    return resolver;
}

and my login.html is as follows

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
  xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head>
    <title>Spring Security Example </title>
</head>
<body>
    <div th:if="${param.error}">
        Invalid username and password.
    </div>
    <div th:if="${param.logout}">
        You have been logged out.
    </div>
    <form th:action="@{/home}" method="post">
        <div><label> User Name : <input type="text" name="username"/> </label></div>
        <div><label> Password: <input type="password" name="password"/> </label></div>
        <div><input type="submit" value="Sign In"/></div>
    </form>
</body>

Configure your TemplateResolver as follows:

@Configuration
public class ThymeleafConfig {

    @Bean
    public TemplateResolver defaultTemplateResolver() {
        TemplateResolver resolver = new TemplateResolver();
        resolver.setResourceResolver(thymeleafResourceResolver());
        resolver.setPrefix("classpath:/templates/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode("HTML5");
        resolver.setCharacterEncoding("UTF-8");
        resolver.setCacheable(true);
        return resolver;
    }

    @Bean
    public SpringTemplateEngine templateEngine(TemplateResolver defaultTemplateResolver) {
        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.addTemplateResolver(defaultTemplateResolver);
        return engine;
    }

    @Bean
    public ThymeleafViewResolver thymeleafViewResolver(SpringTemplateEngine templateEngine) {
        ThymeleafViewResolver resolver = new ThymeleafViewResolver();
        resolver.setTemplateEngine(templateEngine);
        resolver.setCharacterEncoding("UTF-8");
        resolver.setContentType("text/html");
        resolver.setOrder(Ordered.LOWEST_PRECEDENCE - 5);
        return resolver;
    }
}
