在SpringBoot与SpringCloud环境下，使用Feign时遇到的bean注册冲突问题，具体表现为FeignClientSpecification无法注册，已有同名bean存在。解决办法是在配置文件中启用bean定义覆盖。

feign 报错:

环境:

Spring Boot : v2.1.5.RELEASE
Spring cloud: Greenwich.SR1
openfeign: 2.1.1.RELEASE
nacos discovery : 0.2.2.RELEASE

错误信息:

07-26 11:51:56.348 INFO [o.s.b.a.l.ConditionEvaluationReportLoggingListener] -

Error starting ApplicationContext. To display the conditions report re-run your application with ‘debug’ enabled.
07-26 11:51:56.351 ERROR [o.s.b.diagnostics.LoggingFailureAnalysisReporter] -

APPLICATION FAILED TO START

Description:

The bean ‘rainbowbus-ebus-service.FeignClientSpecification’, defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

错误截图:

解决:

在配置文件中添加:

spring:
  main:
    allow-bean-definition-overriding: true
