Eureka客户端无法使用用户名/密码注册到Eureka服务器

Question

版本：

1. 春季安全：6.1.4
2. 春季启动：3.1.4
3. 春云：2022.0.4

用户需要登录才能访问Eureka Server的仪表板。因此，我为 Eureka 服务器配置了 Spring Security，如下所示。

尤里卡服务器：

配置：

@Configuration
@EnableWebSecurity
public class SecurityConfig {

    @Value("${app.eureka.username}")
    private String username;
    @Value("${app.eureka.password}")
    private String password;

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http.csrf(csrf->csrf.ignoringRequestMatchers("/eureka/**"))
                .authorizeHttpRequests((authorize) -> authorize.anyRequest().authenticated())
                .httpBasic(Customizer.withDefaults())
                .formLogin(Customizer.withDefaults());
        return http.build();
    }

    @Bean
    public UserDetailsService userDetailsService() {
        PasswordEncoder encoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
        UserDetails user = User
                .withUsername(username)
                .password(encoder.encode(password))
                .roles("USER")
                .build();
        return new InMemoryUserDetailsManager(user);
    }
}

主要应用程序：

@SpringBootApplication
@EnableEurekaServer
public class DiscoveryServerApplication {

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

}

应用程序属性：

eureka.instance.hostname=localhost
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

server.port=8761
app.eureka.username=eureka
app.eureka.password=password

我只有一项服务：产品服务

主要应用程序：

@SpringBootApplication
@EnableDiscoveryClient
public class ProductServiceApplication {

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

}

应用程序属性：

spring.data.mongodb.uri=mongodb://127.0.0.1:27017/product

eureka.client.service-url.defautZone=http://eureka:password@localhost:8761/eureka
eureka.client.fetch-registry=true
eureka.client.register-with-eureka=true
eureka.instance.prefer-ip-address=true
spring.application.name=product-service
server.port=8080

如果我从尤里卡服务器中删除身份验证层并将

eureka.client.service-url.defautZone

更改回

http:/localhost:8761/eureka

，我的系统工作正常。

如何解决这个问题？

我在 Stack Overflow 上发现了一些与我的情况相同的问题。但有两种情况：

1. 该解决方案不适合我的版本（通常是旧版本）：

   • 如何通过基本身份验证确保 Spring Cloud Eureka 服务的安全？
   • https://howtodoinjava.com/spring-boot2/security-rest-basic-auth-example/

2. 该解决方案无法正确解决我的问题：

   • -SpringBoot 3 -Eureka注册服务器-（用户名密码注册问题）
   • spring cloud eureka 服务器示例登录挑战
   • 无法将服务注册为 Eureka 客户端
   • 无法将客户端注册到eureka服务器
   • 无法将服务注册到发现服务器（EUREKA）
   • Spring Eureka 要求用户名密码认证

Answer 1

我遇到了类似的问题，我通过更改我的 application.yaml 文件解决了它。之前是这样的：

eureka:
   client:
     service-url:
       default-zone: http://eureka:password@localhost:8761/eureka

我把它改为：

eureka:
   client:
     serviceUrl:
       defaultZone: http://eureka:password@localhost:8761/eureka
