Description
When upgrading from Spring Boot 3.4.6 ou Spring Boot 3.5.0 my application is unable to start due to the following error:
APPLICATION FAILED TO START
Description:
Parameter 2 of method registrationClient in de.codecentric.boot.admin.client.config.SpringBootAdminClientAutoConfiguration$RestClientRegistrationClientConfig required a bean of type 'org.springframework.boot.http.client.ClientHttpRequestFactoryBuilder' that could not be found.
Thank you for helping in solving this issue.
Hi @bigluds,
SBA is not yet Spring Boot 3.5 ready as Spring Cloud is not yet released for Spring Boot 3.5.
Anyways. When not using Spring Cloud dependencies, SBA should work ootb. We have upgraded to Spring Boot 3.5 in a branch and for Servlet and WebFlux based implementations, SBA starts up as usual. Can you post the spring dependencies you are using in your project and check if your local setup is correct since all dependant ClientHttpRequestFactoryBuilder classes are part of org.springframework.boot:spring-boot:3.5.0.
Dear @SteKoe,
Thanks for reminding that SBA is not yet Spring Boot 3.5 ready. But I require Spring Boot 3.5 because it fixes an issue we have.
You can find below the full dependency tree we have :

Hi @dkorotych, hi @bigluds,
can you share a minimal project that reproduces the issue? I have just added your dependencies and Spring Boot 3.5.0 to this runtime sample (https://github.com/codecentric/spring-boot-admin-runtime-playground/tree/main/eureka/apps/spring-boot-admin) and it just starts.

Hi @SteKoe
You are right, it is not only about libraries, but also about settings. If you turn off virtual threads or client URL, then the application starts normally
Hello @SteKoe
I confirm the feedback given by @dkorotych when I have the spring property spring.threads.virtual.enabled: true the error occurs otherwise it seems to work correctly.
Hello @dkorotych,
thanks for providing the minimal sample. I was able to see the very same effect and the team will dig deeper into it. Accoding to Spring Boot 3.5.0 release notes there might be a breaking change.
@bigluds thanks for confirming the issue with virtual threads, too!
The root cause is this change in Spring Boot 3.5.0:
RestClientAutoConfiguration now applies for reactive web applications that are using virtual threads and have a applicationTaskExecutor bean.
(see Spring Boot 3.5 Release Notes)
We currently assume, that if a RestClient.Builder bean is available that a ClientHttpRequestFactoryBuilder bean is available, too. With the change in Spring Boot, the former will be available in reactive web applications using virtual threads, but the latter won't. Note that a prerequisit for virtual threads in Spring is a Java version >= 21.
As a workaround, you can define your own ReactiveRegistrationClient:
@Bean
public RegistrationClient registrationClient(ClientProperties client, WebClient.Builder webClient) {
if (client.getUsername() != null && client.getPassword() != null) {
webClient = webClient.filter(basicAuthentication(client.getUsername(), client.getPassword()));
}
return new ReactiveRegistrationClient(webClient.build(), client.getReadTimeout());
}
We are still looking for a proper fix in Spring Boot Admin.
