Я написал класс распознавателя представления, когда использовал для этого InternalResourceViewResolver.MvcConfiguration.class


    @Configuration
    @EnableWebMvc
    @ComponentScan
        public class MvcConfiguration extends WebMvcConfigurerAdapter {
        @Override
        public void configureViewResolvers(ViewResolverRegistry registry) {
            InternalResourceViewResolver resolver = new 
    InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/jsp/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        resolver.setViewNames("jsp");
        registry.viewResolver(resolver);
    }
    }

То же самое я упоминал и в application.yml. application.yml is 

spring:
  mvc:
    view:
      prefix: /WEB-INF/jsp/
      suffix: .jsp
      view-names: jsp
  cloud:
    stream:
      kafka:
        binder:
          brokers: localhost:9092
      bindings:
        greetings-in:
          destination: greetings
          contentType: application/json
        greetings-out:
          destination: greetings
          contentType: application/json

Это мой класс контроллера, который отвечает за рендеринг index.jsp MainController.class 

    import java.util.Map;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;

    @Controller
    public class MainController {

        @RequestMapping("/")
        public String home(Map<String, Object> model) {
            model.put("message", "HowToDoInJava Reader !!");
            return "index";
        }
    }

Первый вариант: у нас есть проект [Spring Boot], где у нас нет создал любые конфиги для использования тимелина. Вам просто нужно создать файлы в каталоге ресурсов -> шаблоны [index.html] и просто просто используйте его в вашем контроллере

Вариант два: Установите spring.thymeleaf.template-resolver-order = 0 в файле application.properties. В качестве части следующего шага создайте пользовательский ClassLoaderTemplateResolver

@ Configuration Открытый класс CustomConfig реализует WebMvcConfigurer {

@Bean
public ClassLoaderTemplateResolver yourTemplateResolver() {
    ClassLoaderTemplateResolver configurer = new ClassLoaderTemplateResolver();
    configurer.setPrefix("customLocation/");
    configurer.setSuffix(".html");
    configurer.setTemplateMode(TemplateMode.HTML);
    configurer.setCharacterEncoding("UTF-8");
    configurer.setOrder(0);  // this is important. This way spring //boot will listen to both places 0 and 1
    configurer.setCheckExistence(true    return configurer;
}}

Более подробную информацию можно найти здесь

Если вам нужна также конфигурация безопасности, добавьте следующий код в gradle 

//----------------------------------Thymeleaf----------------------------------//
// https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-thymeleaf
compile group: 'org.springframework.boot', name: 'spring-boot-starter-thymeleaf', version: '2.1.2.RELEASE'
// https://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4
compile group: 'org.thymeleaf.extras', name: 'thymeleaf-extras-springsecurity5', version: '3.0.4.RELEASE'

Создать один файл для 

 @Configuration
@ConditionalOnClass(SpringSecurityDialect::class)
class ThymeleafSecurityDialectConfiguration protected constructor() {

    @Bean
    @ConditionalOnMissingBean
    fun securityDialect(): SpringSecurityDialect {
        return SpringSecurityDialect()
    }
}

Если вы хотите установить каталог JSP для ресурсов -> папка шаблонов, просто обратитесь к этому ответу. этот вопрос уже решен
