您需要创建用户来完成此操作。请参见下面所附的示例。我正在使用内存中的用户进行身份验证。注意，内存中的用户仅用于测试目的。

@Configuration
public class InMemoryUserSecurityAdapter {

@Bean
public SecurityWebFilterChain filterChain(ServerHttpSecurity http) {
    return http
            .authorizeExchange()
            .pathMatchers("/school-library-service/**").authenticated()
            .and().authenticationManager(reactiveAuthenticationManager())
            .authorizeExchange().anyExchange().permitAll().and()
            .httpBasic().and()
            .build();
}

@Bean
ReactiveAuthenticationManager reactiveAuthenticationManager(){
    return new UserDetailsRepositoryReactiveAuthenticationManager(getInMemoryUserDetails());
}

@Bean
public MapReactiveUserDetailsService getInMemoryUserDetails() {
    UserDetails admin = User.withDefaultPasswordEncoder().username("admin1").password("password")
            .roles("ADMIN")
            .build();
    return new MapReactiveUserDetailsService(admin);
}

}
