Spring Boot + Spring Security 的自定义登录页面

Question

Below is my configuration. I navigate to http://localhost:8080 and is redirected to http://localhost:8080/bruceLogin which is expected. But i got page displaying "Whitelabel Error Page. This application has no explicit mapping for /error, so you are seeing this as a fallback...". Note I did have a simple html page called bruceLogin1.html under src/main/resources/template. Any idea what i am missing here?

*Side Note: One sad thing is that spring boot does not provide a mechanism for developer to configure the custom login page using solely properties file.

@SpringBootApplication
@EnableWebSecurity
public class SpringSecurityCatalogApplication  implements WebMvcConfigurer {

    public static void main(String[] args) {
        SpringApplication.run(SpringSecurityCatalogApplication.class, args);
    }


    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/bruceLogin").setViewName("bruceLogin1");
        registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
    }

    @EnableWebSecurity
    @Order(Ordered.HIGHEST_PRECEDENCE)
    class SecurityConfig extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {

             http
             .authorizeRequests()
             .antMatchers("/resources/**").permitAll()
             .anyRequest().authenticated()
             .and()
             .formLogin()
             .loginPage("/bruceLogin")
             .permitAll();
        }
    }
}

Solution: This issue is resolved after I add implementation 'org.springframework.boot:spring-boot-starter-thymeleaf' to my build.gradle. Thanks to Pham Thai Thinh for the suggestion
