[microservices openfeign] timeout of openfeign

What I am currently using spring cloud Version is Hoxton.SR9, from spring-cloud-2020.0.0 Started removing a lot of Netflix Components , This is just for better application ribbon.

Because this version openfeign Internally integrated ribbon, Therefore, the ribbon Configuration to achieve changes openfeign And so on .

spring-cloud-2020.0.0 Version start , This configuration is invalidated , Available by change Request.Options, In order to achieve ribbon This effect .

Global configuration

ribbon Method to modify the timeout

# Set up feign Client timeout (OpenFeign The default support ribbon)
ribbon:
  # The time taken to establish a connection , It is suitable for normal network conditions , The time taken to connect the two ends 
  ReadTimeout: 5000
  # It refers to the time taken to read the available resources from the server after the connection is established 
  ConnectTimeout: 5000

Request.Options Method to modify the timeout

problem ：if the request should follow 3xx redirections.

Configuration class mode

import feign.Request;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.concurrent.TimeUnit;

/** * @author issavior */

    /** *  Timeout configuration  */
    @Bean
    public Request.Options options() {
    
        
        return new Request.Options(5, TimeUnit.SECONDS,
                5, TimeUnit.SECONDS, true);
    }

Configuration file mode

feign:
  client:
    config:
      #  Provider's service name 
      default:
        # Request log level 
        loggerLevel: FULL
        # Set as default contract （ Revert to native annotations ）
#        contract: feign.Contract.Default
        #  Connection timeout , Default 2s, The setting unit is milliseconds 
        connectTimeout: 5000
        #  Request processing timeout , Default 5s, The setting unit is milliseconds .
        readTimeout: 5000

Local configuration

feign:
  client:
    config:
      #  Provider's service name 
      ossa-service-producer:
        # Request log level 
        loggerLevel: FULL

        connectTimeout: 5000
        #  Request processing timeout , Default 5s, The setting unit is milliseconds .
        readTimeout: 5000

The source code parsing

Relevant source code sorting 【 I only cut a few source images , I'm sure you old fans can understand // The dog's head lives 】

1. Here, first initialize , The default connection and read times are 1000 millisecond , Load into memory .
   
   
   

2. If in the configuration file , Yes ribbon Related configuration , Then refresh / Overwrite the corresponding value in memory .
