Spring 启动集成 FF4j 的 REST 应用程序。如何修复依赖库的 mvc 映射？
Spring boot REST application integrating FF4j. How to fix mvc mapping for dependent library?
在我的应用程序中集成 FF4j 我遇到了一系列问题。它最终集成在 recommendation 之后。
推荐的简短描述是：
- 删除 thymeleaf 的自动配置；
- 添加 ff4j-web
使用的旧 thymeleaf 版本 2.1.4.RELEASE
写一个配置class像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;
}
}
推荐中遗漏的细节是 maven 排除：

但是没用

可以用
修复
registry.addResourceHandler("/static/**")
.addResourceLocations("classpath:/static/");
但是 ff4j servlet 在我的应用程序中无法正常工作：
WARN o.s.w.s.PageNotFound - No mapping for GET /features
问题
我检测到 FF4jServlet 初始化并注册了所有 required 控制器，但我不清楚为什么它不起作用...
有什么解决办法吗？

有两个控制台。您要访问哪一个？
