spring-native is there any certain result for support resttemplate with eureka and loadbalancer

get demo [BlockingLoadbalancer] from https://github.com/spring-projects-experimental/spring-native/pull/1143 native compile is ok，then native-image run successfully

after add hits in main class [BlockingLoadbalancerClienSampleApplication]

but i get error when try a rest test ,and i have no idea to fix，so is there any certain result for support resttemplate with eureka

need help @OlgaMaciaszek

I get a weird thing，rewrite class can work on jvm run，but not on native run

May 07 '22 02:05 enderwsp

change to webclient instead of resttemplate

I get same error，

Hello @enderwsp , Spring Cloud LoadBalancer does not yet have native support.

May 16 '22 13:05 OlgaMaciaszek

Waiting for child context support in Spring Framework to be introduced before we can provide Spring Cloud LoadBalancer support.

Spring Native is now superseded by Spring Boot 3 official native support, see the related reference documentation for more details.

As a consequence, I am closing this issue, and recommend trying your use case with latest Spring Boot 3 version. If you still experience the issue reported here, please open an issue directly on the related Spring project (Spring Framework, Data, Security, Boot, Cloud, etc.) with a reproducer.

Thanks for your contribution on the experimental Spring Native project, we hope you will enjoy the official native support introduced by Spring Boot 3.
