File application.properties

logging.level.root=INFO

File CertificateSpringApplication.java

package vy.certificate_spring;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class CertificateSpringApplication {

    public static void main(String[] args) {
        SpringApplication.run(CertificateSpringApplication.class, args);
    }

}

File FooController.java

package vy.certificate_spring.account.web;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller("/foo")
public class FooController {

    @GetMapping("/bar")
    public String bar(){
        return "bar";
    }

}

The reference document at here https://docs.spring.io/spring-boot/docs/current/actuator-api/htmlsingle/#loggers.all said go to http://localhost:8080/actuator/loggers , but I see it did not work.

Why Spring Boot actuator logger end-point did not work?

Answer 1

You have to define which endpoints are exposed using the following property management.endpoints.web.exposure.include. You can add all endpoints using

management.endpoints.web.exposure.include=*
