This application has no explicit mapping for /error, so you are seeing this as a fallback.

推荐答案
I did some study in actuator use in spring boot 2.x.
The actuator use have significant changes. The default endpoint root path is '/actuator' and not'/' as in 1.x. By default only two endpoint(/health, /info) is enable.
#To make all endpoints enable set
management.endpoints.web.exposure.include=*
#To specifically enable one endpoint(/beans) set
management.endpoint.beans.enabled=true
#Or we can create a WebSecurity bean like this:
@Bean
public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http){
return http.authorizeExchange()
.pathMatchers("/actuator/**").permitAll()
.anyExchange().authenticated()
.and().build();
}
#Remember in spring boot 1.x all this issues was resolved by setting the bellow but it is #depreciated in 2.x
management.security.enabled=false
#By default the base path is '/actuator' but can be changed by setting
management.endpoints.web.base-path= /<Mypath>
