Интеграция FF4j
в мое приложение У меня есть очередь проблем. Интегрированный в конечном итоге рекомендация .
Краткое описание рекомендации:
- Удалить автоконфигурацию тимелина;
- Добавьте старую версию 2.1.4 тимилиста. RELEASE, которая используется ff4j-web
Написать класс конфигурации, например FF4JWebConfiguration:
@Configuration
@ConditionalOnClass({ConsoleServlet.class, FF4jDispatcherServlet.class})
@AutoConfigureAfter(FF4JConfiguration.class)
public class FF4JWebConfiguration extends SpringBootServletInitializer {
@Bean
public ServletRegistrationBean servletRegistrationBean(ConsoleServlet ff4jConsoleServlet) {
return new ServletRegistrationBean(ff4jConsoleServlet, "/ff4j-console");
}
@Bean
@ConditionalOnMissingBean
public ConsoleServlet getFF4jServlet(FF4j ff4j) {
ConsoleServlet ff4jConsoleServlet = new ConsoleServlet();
ff4jConsoleServlet.setFf4j(ff4j);
return ff4jConsoleServlet;
}
@Bean
public ServletRegistrationBean ff4jDispatcherServletRegistrationBean(FF4jDispatcherServlet ff4jDispatcherServlet) {
return new ServletRegistrationBean(ff4jDispatcherServlet, "/ff4j-web-console/*");
}
@Bean
@ConditionalOnMissingBean
public FF4jDispatcherServlet getFF4jDispatcherServlet(FF4j ff4j) {
FF4jDispatcherServlet ff4jConsoleServlet = new FF4jDispatcherServlet();
ff4jConsoleServlet.setFf4j(ff4j);
return ff4jConsoleServlet;
}
}

...
это можно исправить с помощью
registry.addResourceHandler("/static/**")
.addResourceLocations("classpath:/static/");
Но сервлеты ff4j не работают в моем приложении:
WARN o.s.w.s.PageNotFound - No mapping for GET /features
Вопрос
Я обнаружил, что FF4jServlet
инициализировал и зарегистрировал все необходимые контроллеры, но мне не ясно, почему он не работает ...
Есть идеи как это исправить?
