SpringCloud Feign消费Eureka服务报错

SpringCloud Feign消费Eureka服务报com.netflix.client.ClientException: Load balancer does not have available server for client: user

关于这个错误,网上一搜一大把,我抛出我遇到的问题

我把调用外部系统放在一个 client 的子model里头,用包扫描的方式

出现 Feign com.netflix.client.ClientException: Load balancer does not have available server for client: user

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})@ComponentScan(basePackages = "com.XXX")@Slf4j@Configuration@EnableScheduling@EnableTransactionManagement@EnableEurekaClient@EnableFeignClients(basePackages = "com.XXX.client")

然后改成这种class扫描方式,运行调用OK

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})@ComponentScan(basePackages = "com.XXX")@Slf4j@Configuration@EnableScheduling@EnableTransactionManagement@EnableEurekaClient@EnableFeignClients(basePackageClasses = {com.XXX.client.base.AccountClient.class,        com.XXX.client.base.ExchangeOtcClient.class,        com.XXX.client.mkt.MktClient.class})

为什么会这样,我还没搞明白,先记录下.
