【解决问题】Springboot 启动报错：FactoryBean threw exception on object creation； nested exception is java.lang.

Springboot项目整合了Feign，一直都启动好好的，加了几个接口后准备测试时就启动不了了，一直报以下错误：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.ks.feign.xxxFeign': FactoryBean threw exception on object creation; nested exception is java.lang.UnsupportedOperationException

value值缺少一致报错
加上value就好了
