• FeignClient 2.2.X使用okHttpClient初探

    关于feign发送请求目前收集一共有3+1种client。

    1. Jdk自带urlconnection(默认且无池化）
    2. ApachHttpClient
    3. okHttpClient
    4. google 客户端（未求证）

    Yaml配置项目见文章底部

    目前在网络上看到此写法（反正2.2.10版本下面参数红色不会生效，请不要乱抄）

    feign:
      client:
        config:
          default: # default全局的配置
            loggerLevel: BASIC # 日志级别，BASIC就是基本的请求和响应信息
      httpclient:
        enabled: true # 开启feign对HttpClient的支持
        max-connections: 200 # 最大的连接数
        max-connections-per-route: 50 # 每个路径的最大连接数

     上述两个值在httpclient 里配置，okhttp仅仅只提供  enabled 属性，池化参数在httpclient 参数项目里配置

     

    正确的配置方法在下方，已经求证，最终请参考官方文档，在本文底部

     

     

    关于timeout，连接超时默认是毫秒单位。

     

    Yaml配置文件属性见官方文档（官方提供2.2.10文档）
