Eureka client can not register to Eureka server with user/pass

by

Version:

  1. Spring Security: 6.1.4
  2. Spring Boot: 3.1.4
  3. Spring Clound: 2022.0.4

User need to login to access Eureka Server ‘s dashboard. So, I configured spring security for Eureka server like below

Eureka Server:

  • Config
@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);
    }
}
  • Main app:
@SpringBootApplication
@EnableEurekaServer
public class DiscoveryServerApplication {

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

}
  • application.properties
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

I have one service: product-service

  • Main app:
@SpringBootApplication
@EnableDiscoveryClient
public class ProductServiceApplication {

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

}
  • application.properties
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

To clear, my system work fine if I remove auth layer from eureka server and change

eureka.client.service-url.defautZone back to http:/localhost:8761/eureka
