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;
}
}
