Mastering Spring Boot's Actuator
summary
Spring Boot 2.0 Actuator groups endpoints under \/actuator base path, adds Jersey and WebFlux adapters, and provides an endpoint API using annotations like Endpoint, ReadOperation, WriteOperation with selector-to-path and query-parameter mapping; shutdown is disabled by default, health has configurable show-details rules, scheduled-tasks and sessions endpoints appear by default, per-endpoint caching and Micrometer for multi-dimensional metrics, and escape hatches (servlet/controller endpoints) plus a gotcha: compile with -parameters for JSON body binding.
