Request processing failed; nested exception is feign.codec.EncodeException: Could not write JSON: Infinite recursion (*Error); nested exception is com.fasterxml.jackson.databind.JsonMappingException:

（微服务间的内部调用，使用 feign ，出现的问题）

原因，我在 feign 里面，加了  HttpServletRequest request 参数 (feign方法所包含的参数就像个对象，不能带 HttpServletRequest request )

删除 HttpServletRequest request 就行了

报错：Request processing failed; nested exception is feign.codec.EncodeException
