requestMappingHandlerMapping has 2 potential beans when actuator is active from spring boot version 2.7

I did small sample project to show behavior which we are getting on bigger project. We are using actuator endpoints and same time we have a service where we are autowiring RequestMappingHandlerMapping. Our code was working in spring boot 2.6.x, but in version 2.7.x (even in latest 2.7.2) it is not working. When actuator is not put as dependency then this autowiring works, but in our case application will not start and we are getting this error:

Parameter 0 of constructor in com.example.demo.VersionInfoService required a single bean, but 2 were found:
	- requestMappingHandlerMapping: defined by method 'requestMappingHandlerMapping' in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]
	- controllerEndpointHandlerMapping: defined by method 'controllerEndpointHandlerMapping' in class path resource [org/springframework/boot/actuate/autoconfigure/endpoint/web/servlet/WebMvcEndpointManagementContextConfiguration.class]

sample application for reproducing build.gradle

plugins {
    id 'org.springframework.boot' version '2.7.2'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-web'
}

VersionInfoService.java

package com.example.demo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

@Service
public class VersionInfoService {

RequestMappingHandlerMapping handlerMapping;

  @Autowired
  public VersionInfoService(RequestMappingHandlerMapping handlerMapping) {
    this.handlerMapping = handlerMapping;
  }
}

Demo1Application.java

package com.example.demo;

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

@SpringBootApplication
public class Demo1Application {

    public static void main(String[] args) {
        SpringApplication.run(Demo1Application.class, args);
    }

}

Or alternatively handling just multiple beans of that type - that’s what we ended up doing. E.g.

@Service
public class VersionInfoService {

  List<RequestMappingHandlerMapping> handlerMappings;

  public VersionInfoService(List<RequestMappingHandlerMapping> handlerMappings) {
    this.handlerMappings = handlerMappings;
  }
}

Plus whatever changes are needed that call the handlerMapping. In our case these were relatively straight-forward - we’re just looking in a list of mappings instead of a single one now.

Thanks for clarification, solution and extending release notes.
