我想用Spring授权服务器项目构建一个授权服务器。现在我想使用AuthorizationGrantType. PASSWORD。
我从Spring授权服务器项目的示例中开发了一个演示项目，但是，当我尝试使用 http：//localhost：9000/oauth2/token？grant_type=password&username=user&password=pass（我使用client_id和client_secret作为Postman中的基本授权）请求获取令牌时，我得到了403。
我错过了什么？

授权服务器配置类：

        RSAKey rsaKey = generateRsa();
        JWKSet jwkSet = new JWKSet(rsaKey);
        return (jwkSelector, securityContext) -> jwkSelector.select(jwkSet);
    }
    
    private static RSAKey generateRsa() {
        KeyPair keyPair = generateRsaKey();
        RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
        RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate();
        return new RSAKey.Builder(publicKey)
                .privateKey(privateKey)
                .keyID(UUID.randomUUID().toString())
                .build();
    }
    
    private static KeyPair generateRsaKey() {
        KeyPair keyPair;
        try {
            KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
            keyPairGenerator.initialize(2048);
            keyPair = keyPairGenerator.generateKeyPair();
        } catch (Exception ex) {
            throw new IllegalStateException(ex);
        }
        return keyPair;
    }    
}

默认安全配置类：

import org.springframework.security.web.SecurityFilterChain;

@EnableWebSecurity
public class DefaultSecurityConfig {
    
    @Bean
    SecurityFilterChain defaultSecurityFilterChain(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .cors().disable()
                .authorizeRequests(authorizeRequests ->
                        authorizeRequests
                                .anyRequest()
                                .authenticated()
                );
        return http.build();
    }
    
    @Bean

        UserDetails userDetails = User.withDefaultPasswordEncoder()
                .username("user")

                .build();
        return new InMemoryUserDetailsManager(userDetails);

我在日志中发现了这条消息，可能与此相关：
