Spring actuator in 2.7 not available get 404 - spring-boot

Question

i am trying to get actuator refresh to work and i cant seem to get it to work. I keep getting 404. The application is basic hello world, have not added anything other than a controller which responds with "Hello". That all works.. but i cant seem to get access to the health or info endpoints.. i read these should be available
my versions are:
Gradle:
plugins {
id 'org.springframework.boot' version '2.7.3'
id 'io.spring.dependency-management' version '1.0.13.RELEASE'
id 'java'
}
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'
repositories {
mavenCentral()
}
ext {
set('springCloudVersion', "2021.0.3")
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.cloud:spring-cloud-starter-config'
implementation 'org.projectlombok:lombok:1.18.22'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
implementation 'org.springframework.boot:spring-boot-starter-actuator:2.7.3'
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
tasks.named('test') {
useJUnitPlatform()
}
Tried:
Application.properties
server:
port: 9999
server:
port: 9999
management:
health:
refresh:
enabled: true
This too:
management:
info:
env:
enabled: true
i dont think the last one is even available in 2.7
Im using the latest actuator which is 2.7.3, and the url im trying is
http://localhost:9999/actuator/health

I'm upgrading our application's spring boot version from 2.6 to 2.7. I had a similar problem, the actuator endpoint did not show up when I changed spring-boot-starter-actuator version from 2.6.11 to any 2.7.* version.
But when I added spring-boot-actuator-autoconfigure dependency manually, the actuator started to work as before.
So try to add org.springframework.boot:spring-boot-actuator-autoconfigure to your to dependencies.
I cant figure out why this solves the problem. It should work without adding this dependency manually. Maybe the changes in the spring autoconfiguration somehow affected the actuator auto configuration.
