Add spring-cloud-openfeign support

[nightlonely7]

spring-boot: 2.4.5
spring-native: 0.9.2
when I ran my app's image after gradle bootBuildImage I got the following errors: ( no errors before spring-native integrated)

Hope it will be fixed soon :)

Hello, any news about this or a way to make feignclients work in spring native?

Edit: It would be great if this issue were incorporated into 0.12.0!

[rab2215]

Same issue here, hoping for an ETA?

I have the same issue with spring-cloud-starter-openfeign.

Is there any workaround, please?

I was able to make it work here with minimal changes (and lots of hints and jdkproxys), your specific error is because @EnableFeignClients when it receives a package tries to reflect at runtime... If you declare clients directly in the annotation:
@EnableFeignClients(clients=`{Client1.class}) it will work.

[stefanof95]

Thank you for your help. It works with the following HInts:

@configuration
@NativeHint(trigger = FeignConfiguration.class,
types = {
@typehint(types = WebServiceClient.class),
@typehint(types = FeignClient.class),
@typehint(typeNames = "org.springframework.cloud.openfeign.FeignClientSpecification"),
@typehint(types = FeignClientsConfiguration.class)
},
jdkProxies = {
@JdkProxyHint(types = WebServiceClient.class),
@JdkProxyHint(types = {PathVariable.class, SynthesizedAnnotation.class}),
@JdkProxyHint(types = {RequestHeader.class, SynthesizedAnnotation.class}),
@JdkProxyHint(types = {RequestBody.class, SynthesizedAnnotation.class}),
@JdkProxyHint(types = {RequestParam.class, SynthesizedAnnotation.class})
}
)
@EnableFeignClients(clients = {WebServiceClient.class})
public class FeignConfiguration {
}

^ this worked on Spring Native 0.10.5 and Spring Boot 2.5.x

Sadly this is broken again on Spring Native 0.11.0 and Spring Boot 2.6.1. The above workaround no longer works.

Has anyone managed to find an alternative workaround?

[sdeleuze]

@OlgaMaciaszek Could you please confirm spring-cloud-openfeign requires child application context support?

[spencergibb]

it does require child application contexts

[sdeleuze]

Thanks @spencergibb, so I confirm this won't be supported in 0.11.x, but we are well aware of that limitation in our support plan to have this proper supported in 2022. If you really need it, please use Spring Native 0.10.x. Thanks for your understanding.
