Spring Boot Cloud ACTUATOR / конечная точка обновления: исключение: фильтры не могут быть добавлены в контекст /ROOT, так как контекст был инициализирован

Question

Получение следующего исключения при обновлении облачного приложения весенней загрузки из ACTUATOR (/Refresh). Он работает на отдельном сервере Tomcat. Он использует SpringBootServletInitializer.:

org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is java.lang.IllegalStateException: Filters can not be added to context /ROOT as the context has been initialised

Spring Boot Cloud ACTUATOR / конечная точка перезапуска: Исключение: невозможно добавить фильтры в контекст /ROOT, так как контекст был инициализирован

Следующие 4 фильтра создавали проблему: errorPageFilter, metricsFilter, webRequestLoggingFilter, applicationContextIdFilter

Вот решение:

public class XXXSpringBootServletInitializer  extends SpringBootServletInitializer {
     @Override
     public WebApplicationContext createRootApplicationContext(ServletContext servletContext) {
          // Disable errorPageFilter
          setRegisterErrorPageFilter(false);
          // Disable metricsFilter
          System.setProperty("endpoints.metrics.filter.enabled", "false");
          // Disable applicationContextIdFilter
          System.setProperty("management.addApplicationContextHeader", "false");
          WebApplicationContext oWebApplicationContext = super.createRootApplicationContext(servletContext);    
          return oWebApplicationContext;
     }
}

Отключить webRequestLoggingFilter:

@SpringBootApplication(exclude={TraceWebFilterAutoConfiguration.class})
public class SIGBootApplication {
    ........
}
