您可以通过注册 ClientRegistrationRepository 豆子：

@Bean
public ReactiveClientRegistrationRepository clientRegistrations() {
    ClientRegistration clientRegistration = ClientRegistration.withRegistrationId("gateway")
        .clientId("gateway")
        .clientSecret("secret")
        .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
        .redirectUriTemplate("{baseUrl}/login/oauth2/code/{registrationId}")
        .scope("openid", "profile", "email", "resource.read")
        .authorizationUri("http://localhost:8090/uaa/oauth/authorize")
        .tokenUri("http://uaa:8090/uaa/oauth/token")
        .userInfoUri("http://uaa:8090/uaa/userinfo")
        .userNameAttributeName(IdTokenClaimNames.SUB)
        .jwkSetUri("http://uaa:8090/uaa/token_keys")
        .build();
    return new InMemoryReactiveClientRegistrationRepository(clientRegistration);
}

并提供 WebSecurityConfigurerAdapter （或 SecurityFilterChain 如果您使用的是springsecurity5.4或更高版本），则可以通过 httpSecurity.oauth2Login() :

@EnableWebSecurity
public class UiSecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests(authorize -> authorize
                .anyRequest().authenticated()
            )
            .oauth2Login(withDefaults());
    }
}
