JAVA-服务之间调用,报错:java.io.IOException：你的主机中的软件中止了一个已建立的连接

 首先说下业务场景吧,A服务(流程服务)去调用B服务(应用服务),然后在B服务(应用服务)中对业务数据处理时,需要去循环调用A服务(流程服务)的流程数据去进行返回对象的数据组装.

然后问题就出现在A服务调用B服务的时候,B服务还在跑,A服务已经挂了,报错如下:

刚开始看见这个,以为是前端的问题,是不是前端接口超时的时间设短了,因为我这个接口数据量有点大.

排除前端的问题后,开始看服务调用的接口传参,然后就发现不对劲.

页面上调用接口,直接返回500,服务异常了,用api工具调用

 信息更详细了,发现服务之间调用用的GET请求,表单提交,导致这个接口拼接了N个参数,看着太难受了.....看报错是连接超时,马上看下nacos配置,看看超时的配置是怎么配的

feign:
  httpclient:
    enabled: true
  client:
    config:
      default:
        #超时时间默认为1s
        #建立连接所用的时间，适用于网络状况正常的情况下，两端连接所需要的时间
        ConnectTimeOut: 10000
        #指建立连接后从服务端读取到可用资源所用的时间
        ReadTimeOut: 10000

加上这段配置后,连接超时的问题就完美解决了,返回也就正常了
