spring cloud provider报“Error parsing HTTP request header”，feign端报“Read timed out“

这两天在调试spring cloud feign+hystrix报了如下错误：

spring cloud provider报“Error parsing HTTP request header”，feign端报“Read timed out“

provider报错信息：

-- ::, [http-nio--exec-] DEBUG org.apache.coyote.http11.Http11Processor: - Error parsing HTTP request header
java.io.EOFException: null
    at org.apache.tomcat.util.net.NioEndpoint$NioSocketWrapper.fillReadBuffer(NioEndpoint.java:)
    at org.apache.tomcat.util.net.NioEndpoint$NioSocketWrapper.read(NioEndpoint.java:)

    at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:)

feign报错信息：

Exception in thread "pool-10-thread-14" feign.RetryableException: Read timed out executing 

针对provider报错信息需要修改的配置如下：

server:
  port:
  tomcat:
      max-http-header-size:     --这里

针对feign端报错信息需要调整的配置如下：

feign:
  client:
    default:
      #这里时间一定要调长，否则feign客户端会报ReadTimeOut  服务端报Error parsing HTTP request header
      connectTimeout:
      readTimeout:
      loggerLevel: basic
