/actuator/info Endpoint not working with spring boot 2.5.0

Question

I upgraded spring boot version in my app from 2.4.4 to 2.5.0 and it stopped exposing /actuator/info endpoint. Here is the pom.xml and application.yml

application.yml

management:
  endpoints:
    jmx:
      exposure:
        include: "health,info"

With spring boot parent version 2.4.4, the application is able to expose info endpoint but not with 2.5.0.

Answer 1

The correct property for exposing actuator urls over http is management.endpoints.web.​exposure.exclude (web instead of jmx).

In your case, info was exposed earlier not because you had the property you've provided but because it was exposed by default (along with health). But in 2.5.0 it becomes hidden, so now you need to expose it manually.

Answer 2

Add this to application properties to expose the /info endpoint.

management.info.env.enabled = true

Answer 3

In my case, which was a silly mistake, I had the following dependency:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-actuator</artifactId>
    </dependency>

Instead of:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

So I kept on getting Whitelabel Error Page 404 Not found on all /actuator calls

In application.properties

#Actuator
management.endpoints.jmx.exposure.include=health,info,env,beans
management.endpoints.web.exposure.include=health,info,env,beans

Answer 4

Here is a basic gradle build (kotlin dsl) to have three default available endpoints for actuator:

gradle.build.kts

build.gradle.kts
    //Global variables
    val junitVersion = "5.8.2"
    val springVersion = "2.6.4"
    val springWebVersion = "5.3.16"
    
    plugins {
        java
        id("org.springframework.boot") version "2.6.4"
    
    }
    
    group = "org.example"
    version = "1.0-SNAPSHOT"
    
    repositories {
        mavenCentral()
    }
    
    dependencies {
        testImplementation("org.junit.jupiter:junit-jupiter-api:$junitVersion")
        testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:$junitVersion")
    
        //spring boot
        implementation("org.springframework:spring-web:$springWebVersion")
        implementation("org.springframework.boot:spring-boot-starter-web:$springVersion")
        implementation("org.springframework.boot:spring-boot-starter-actuator:$springVersion")
        testImplementation("org.springframework.boot:spring-boot-starter-test:$springVersion")
    
    }
    
    tasks.getByName<Test>("test") {
        useJUnitPlatform()
    }

application.yml

#tomcat
server:
  port: 7999

#actuator
management:
  endpoints:
    web:
      exposure:
        include: health,info,env,beans

gradlew bootRun:

Actuator endpoint, e.g.:

http://localhost:7999/actuator/health
