What versions do SpringBoot, Springcloud and feign-reactive support?

[SnowZhouJ]

In my project，2.2.1 Springboot , Hoxton.RC1 SpringCloud, 1.0.41 reactivefeign，But it doesn't start。 error: Caused by: java.lang.IllegalStateException: Failed to introspect annotated methods on class reactivefeign.spring.config.ReactiveFeignClientsConfiguration I tried all 2.2.x versions, none of which started. Why? I tried 2.1.2 springboot, 1.0.22 reactivefeign, Greenwich SpringCloud is available.

Here is the reactive feign sample project that I'v just updated to latest feign and Hoxton reactive feign sample. It starts and works well. I'd like you to provide full stack trace of your error. And the best option is the reproducible test (you can create it in your fork of the sample project)

[SnowZhouJ]

@kptfh Thanks. I used the Feign sample project from reactive feign sample. . I think it might be a jar version compatibility issue. `2019-12-17 09:43:18.856 WARN 59124 --- [ main] s.c.a.AnnotationConfigApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [reactivefeign.spring.config.ReactiveFeignClientsConfiguration]; nested exception is java.lang.IllegalStateException: Failed to introspect annotated methods on class reactivefeign.spring.config.ReactiveFeignClientsConfiguration 2019-12-17 09:43:18.864 WARN 59124 --- [ main] onfigReactiveWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'feignReactiveApplication': Unsatisfied dependency expressed through field 'reactiveFeignClient'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.example.demo.GreetingReactive': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [reactivefeign.spring.config.ReactiveFeignClientsConfiguration]; nested exception is java.lang.IllegalStateException: Failed to introspect annotated methods on class reactivefeign.spring.config.ReactiveFeignClientsConfiguration 2019-12-17 09:43:18.925 INFO 59124 --- [ main] ConditionEvaluationReportLoggingListener :

[kptfh]

what is the Java version? seems that now auto-configuration of Reactive Feign is compatible with java 11 only

[SnowZhouJ]

@kptfh I'm using java 8 .

[SnowZhouJ]

Is it compatible with java8?

[kptfh]

fixed try 1.0.44 with java 8

[SnowZhouJ]

@kptfh Thanks, After the update, the project can run normally. I have another question, how to forward the header? Could you provide a sample? @Headers is invalid.

[kptfh]

check this pass header
