我正在开发核心银行解决方案。我有两个微服务，分别称为 account-cmd-service 和 customer-service。我一直在尝试使用 FeignClient 通过客户服务的 id 获取客户。开发环境没有问题，但是Docker端有问题。
我一直在尝试覆盖 docker-compose.yml 文件中的 spring.feign.customer.client 属性 http://客户服务:5000/。
如何联系客户服务？
{
"message": "Error while processing - feign.RetryableException: Connection refused (Connection refused) executing GET http://localhost:5000/api/v1/customer/get/1.",
"id": "21d65b99-c85f-44ff-9763-ed82ff1c39cc"
}
这是我用于获取客户的 ICustomerService。
@Service
@FeignClient(name = "customer-service", url = "${spring.feign.customer.client}")
public interface ICustomerService {
@GetMapping("/api/v1/customer/get/{customerId}")
Object getCustomerById(@PathVariable Long customerId);
}
这是 account-cmd-service 的 application.properties。
server.port=5002
#Mongo Config
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=accountcmdb
# RabbitMQ Setup
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
feign.client.config.default.connectTimeout=160000000
feign.client.config.default.readTimeout=160000000
spring.feign.customer.client = http://localhost:5000/
这里是 docker-compose.yml 文件实现。

通过在 docker-compose 文件中将容器置于同一网络中已经解决了这个问题。
