如何在不删除 Actuator 的情况下在 Spring Boot 中开发我自己的 /env 端点？

Question

I have a Spring Boot application (Java 8, Spring Boot 1.5.9) with Actuator, but I need to write my own response for the /env endpoint. I tried disabling it with the property endpoints.env.enabled=false but the response that I get is an HTTP 500 instead of an HTTP 404 .

Is there any way to write my own /env endpoint without remove all the Actuator library of the project?

Thanks in advance.

I manage to do this in two steps:

First, re-map the /env path to something else in the application.properties file, eg:

management.endpoints.web.path-mapping.env=default-env

Second, write our own endpoint implementation for the /env endpoint, eg

@RestController
public class EnvController {
    @GetMapping(value="/actuator/env")
    public ResponseEntity<String> env() {
        return ResponseEntity.ok("My custom env endpoint");
    }
}
