Hello @lin1005q - thanks for providing a sample. Will take a look tomorrow.

OlgaMaciaszek commented 2 years ago

Hello @lin1005q. This happens, because you've added the LB configuration bean to a class where your root application context is configured. As you can read in the docs, classes containing LB configuration beans should be passed as configuration argument of the @LoadBalancerClient annotation and they should not be annotated with @Configuration (or any meta-annotations that include it, such as @SpringBootApplication). This way, the beans will be created in specific child contexts, a different one for every load-balanced service. This change fixes the setup.

lin1005q commented 2 years ago

Thank you very much. How can it be set as the global default, which is automatically configured like xxx-spring-boot-starter. No need to manually add the @LoadBalancerClient annotation

OlgaMaciaszek commented 2 years ago

If you want to set a custom configuration, you need to use the annotation. If you want to have a default for many clients, you can use @LoadBalancerClients(defaultConfiguration= CustomConfig.class). Please read the docs - it's all described there.
