org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/bonita] No Spring WebApplicationInitializer types detected on classpath

Hi people, What is this error ?

The Bonita Server 7.5.4 worked well several days, but surprisingly the browser is empty and waiting for the server.

This made the server not work.
