java - Java 假客户端连接被拒绝

Question

我有一个针对我正在使用的微服务之一的模拟器。我的微服务和模拟器都部署在本地主机上，我可以从curl调用模拟器，但是当从Java Feign客户端调用它时，我收到来自Feign客户端的connection Refused。1)我已经检查了模拟器是否已启动并在端口上运行

netstat -a
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 0.0.0.0:http-alt        0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:19090           0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:19091           0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:19092           0.0.0.0:*               LISTEN

2) 我能够从 Curl 调用模拟器

curl -v -X GET -H "X-B3-ParentSpanId:9b9c585fae4b6909" -H "X-B3-Sampled:1" -H "X-B3-TraceId:897aa305e5cd4a0e9b9c585fae4b6909"     http://127.0.0.1:19092/restservices/oda/v1/flow/partner/BBY/reference/29920299209700018540
Note: Unnecessary use of -X or --request, GET is already inferred.

但是当通过 Feign 客户端从我的微服务调用它时，它给我连接拒绝错误

"label" : "feign.RetryableException: Connect to  [localhost/127.0.0.1] failed: Connection refused executing GET http://127.0.0.1:19092/restservices/oda/v1/flow/partner/BBY/reference/29920299209700018540"

Answer 1

我解决了这个问题
原来有两个相同的远程服务
其中一个没有开始成功
所以我拒绝了重复的服务
希望这能解决您的问题
