我有以下eureka服务器配置波姆。xml

<parent>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>Angel.SR6</version>
    <relativePath />
</parent>

<properties>
    <java.version>11</java.version>
</properties>

    <dependency>

这是eureka客户端的配置。波姆。xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.6.RELEASE</version>

        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        <version>2.2.6.RELEASE</version>
    </dependency>
</dependencies>

应用尤里卡客户的yml:

eureka:
  client:
    serviceUrl:
      default:
        zone: http://user:pass@localhost:8761/eureka/
  instance:
    hostname: localhost
    password: pass
security:
  user:
    username: user
    password: pass

Eureka服务器正常启动。然而,当我运行eureka客户端时,这是启动过程的结果。在客户端:

[WARN ] 2021-02-21 21:22:28 [DiscoveryClient-InstanceInfoReplicator-0] RetryableEurekaHttpClient - Request execution failure with status code 401; retrying on another server if available
[WARN ] 2021-02-21 21:22:28 [DiscoveryClient-InstanceInfoReplicator-0] DiscoveryClient - DiscoveryClient_ACCOUNT-SERVICE/localhost:account-service - registration failed Cannot execute request on any known server
com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

在服务器端:

2021-02-21 21:22:28.541  INFO 5208 --- [nio-8761-exec-1] o.s.b.a.audit.listener.AuditListener     : AuditEvent [timestamp=Sun Feb 21 21:22:28 CET 2021, principal=anonymousUser, type=AUTHORIZATION_FAILURE, data={type=org.springframework.security.access.AccessDeniedException, message=Access is denied}]

如果eureka客户注册过程未获得401结果的授权,但我提供了正确的凭证,这会是什么问题?

为了让Eureka工作,您需要将一些配置放在适当的位置。在您的eureka服务器服务上,您需要使用@EnableEurekaServer注释启用eureka服务器,如下所示:

@SpringBootApplication
@EnableEurekaServer
public class NamingServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(NamingServerApplication.class, args);
    }

在客户端上,需要在应用程序中配置应用程序名称。属性,比如:

spring.application.name=my-application

那应该管用!别忘了改变你的spring云版本!
