Custom metrics can be measured using Meter primitives such as Counter, Gauge, Timer, and DistributionSummary: Spring Boot Actuator Metrics allows you to define and measure custom metrics using various Meter primitives.

A. Allow access to a method based on user identity.

This is true because the @PreAuthorize annotation can use the principal object to access the user identity and check if it matches a certain condition. For example, we can use the following expression to allow access only to the user with the username “admin”:

@PreAuthorize(“principal.username == ‘admin’”)

This is true because the @PreAuthorize annotation can use the hasRole, hasAnyRole, or hasAuthority methods to check if the user has a certain role or authority. For example, we can use the following expression to allow access only to users who have the role “ADMIN” or “USER”:

@PreAuthorize(“hasAnyRole(‘ADMIN’, ‘USER’)”)
