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：

2018-06-20 18:23:51,595 [http-nio-8086-exec-5] DEBUG org.apache.coyote.http11.Http11Processor:182 - Error parsing HTTP request headerjava.io.EOFException: null    at org.apache.tomcat.util.net.NioEndpoint$NioSocketWrapper.fillReadBuffer(NioEndpoint.java:1250)    at org.apache.tomcat.util.net.NioEndpoint$NioSocketWrapper.read(NioEndpoint.java:1190)    at org.apache.coyote.http11.Http11InputBuffer.fill(Http11InputBuffer.java:717)    at org.apache.coyote.http11.Http11InputBuffer.parseRequestLine(Http11InputBuffer.java:366)    at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:687)

 

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: 8087  tomcat:      max-http-header-size: 3145728    --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: 60000      readTimeout: 60000      loggerLevel: basic
