spring boot 如何配置RequestContextListener - java报错
如题，我想在初始化完成后加载一些数据到当前内存里，但是spring boot里好像没办法配置RequestContextListener，我的配置如下：
@Configuration
public class Listener {
@Bean
public ServletListenerRegistrationBean<EventListener> getDemoListener(){
ServletListenerRegistrationBean<EventListener> registrationBean
=new ServletListenerRegistrationBean<>();
registrationBean.setListener(new RequestContextListener());
// registrationBean.setOrder(1);
return registrationBean;
}
}
Java获取如下：
((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
一直是空指针，没办法获取HttpServletRequest
