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