Java Eureka客户端无法使用用户通行证注册到Eureka服务器

版本:

1. spring 安全:6.1.4
2. 春舟:3.1.4
3. 春雨:2022.0.4

用户需要登录才能访问Eureka服务器的仪表板.因此，我为Eureka服务器配置了Spring安全性，如下所示.

Eureka服务器:

请注意，情况并非如此.

@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);
    }
}

主打APP:

@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

主打APP:

@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eureka服务器上删除auth Layer并将eureka.client.service-url.defautZone改回http:/localhost:8761/eureka，我的系统就能正常工作.

我怎么才能解决这个问题呢？

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(正常情况下，它是旧版本):

   • How to secure spring cloud eureka service with basic auth?个
   • https://howtodoinjava.com/spring-boot2/security-rest-basic-auth-example/个

2. 该解决方案没有正确解决我的问题:

   • -SpringBoot 3 -Eureka registry server -(username & password registration problem)个
   • spring cloud eureka server example login challenge个
   • Not able to register a service as Eureka Client个
   • Unable to register client to eureka server个
   • Unable to register services to the discovery server (EUREKA)个
   • Spring Eureka asks for username password authentication个
