Integrating FF4j
in my application I've got a queue of issues. Its integrated finally following recommendation.
Short description of recommendation is:
- Remove auto-configuration of thymeleaf;
- Add the old thymeleaf version 2.1.4.RELEASE which is used by ff4j-web
Write a configuration class like 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; }
}
Missed detail in recommendation is maven exclusion:
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf</artifactId>
<version>2.1.4.RELEASE</version>
<exclusions>
<exclusion>
<artifactId>javassist</artifactId>
<groupId>org.javassist</groupId>
</exclusion>
</exclusions>
</dependency>
But it isn't work

until I've added some maven exclusion tricks

...
it can be fixed with
registry.addResourceHandler("/static/**")
.addResourceLocations("classpath:/static/");
But ff4j servlets don't work in my application any way:
WARN o.s.w.s.PageNotFound - No mapping for GET /features
Question
I've detected that FF4jServlet
initialized and registered all required controllers but I'm not clear why it doesn't work...
Is any ideas how to fix it?

Have you tried to look at
https://github.com/ff4j/ff4j-spring-boot-starter-parent/tree/master/ff4j-spring-boot-sample ?
There are two consoles. Which one are you trying to access ?
