我对Spring Security 和使用oauth2身份验证和授权开发springrestapi还很陌生。一切正常，但当我请求刷新令牌时，我得到的错误状态是什么-
org.springframework.security.oauth2.provider.endpoint.tokenendpoint handleexception非法状态异常，需要userdetailsservice。
注意：我正在使用自定义身份验证提供程序对数据库中的用户凭据进行身份验证。
这是我的密码：
web安全配置适配器：

@Configuration
@EnableWebSecurity
public class OAuth2SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Autowired
private ClientDetailsService clientDetailsService;

@Autowired
private CustomAuthenticationProvider authProvider;

@Override
protected void configure(
  AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(authProvider);
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
    .csrf().disable()
    .anonymous().disable()
    .authorizeRequests()
    .antMatchers("/oauth/token").permitAll();
}

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

@Bean
public TokenStore tokenStore() {
    return new InMemoryTokenStore();
}

@Bean
@Autowired
public TokenStoreUserApprovalHandler userApprovalHandler(TokenStore tokenStore){
    TokenStoreUserApprovalHandler handler = new TokenStoreUserApprovalHandler();
    handler.setTokenStore(tokenStore);
    handler.setRequestFactory(new DefaultOAuth2RequestFactory(clientDetailsService));
    handler.setClientDetailsService(clientDetailsService);
    return handler;
}

@Bean
@Autowired
public ApprovalStore approvalStore(TokenStore tokenStore) throws Exception {
    TokenApprovalStore store = new TokenApprovalStore();
    store.setTokenStore(tokenStore);
    return store;
}

}

自定义身份验证提供程序

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {

@Override
public Authentication authenticate(Authentication authentication) 
  throws AuthenticationException {

    String username = authentication.getName();
    String password = authentication.getCredentials().toString();
    Ss_admin_service ss_admin_service = new Ss_admin_service();
    Ss_admin ss_admin = new Ss_admin();
    ss_admin.setA_password(password);
    ss_admin.setA_username(username);
    ss_admin_service.doLogin(ss_admin);
    if(!ss_admin_service.doLogin(ss_admin)) {
        throw new BadCredentialsException("Invalid username/password");
    }
    return new UsernamePasswordAuthenticationToken(username, password, (Collection<? extends GrantedAuthority>) new ArrayList<>());
}

@Override
public boolean supports(Class<?> authentication) {
    return authentication.equals(UsernamePasswordAuthenticationToken.class);
}

}

授权服务器配置

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

private static String REALM="MY_OAUTH_REALM";

@Autowired
private TokenStore tokenStore;

@Autowired
private UserApprovalHandler userApprovalHandler;

@Autowired
@Qualifier("authenticationManagerBean")
private AuthenticationManager authenticationManager;

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {

    clients.inMemory()
        .withClient("my-trusted-client")
        .authorizedGrantTypes("password", "authorization_code", "refresh_token", "implicit")
        .authorities("ROLE_CLIENT", "ROLE_TRUSTED_CLIENT")
        .scopes("read", "write", "trust")
        .secret("secret")
        .accessTokenValiditySeconds(10).//Access token is only valid for 10 sec for testing.
        refreshTokenValiditySeconds(10);//Refresh token is only valid for 10 sec for testing.
}

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    endpoints.tokenStore(tokenStore).userApprovalHandler(userApprovalHandler)
            .authenticationManager(authenticationManager);
}

@Override
public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
    oauthServer.realm(REALM+"/client");
}

}

资源服务器配置

@Configuration
@EnableResourceServer
public class OAuth2ResourceServerConfig extends ResourceServerConfigurerAdapter {

private static final String RESOURCE_ID = "SPRING_REST_API";

@Override
public void configure(ResourceServerSecurityConfigurer resources) {
    resources.resourceId(RESOURCE_ID).stateless(false);
}

@Override
public void configure(HttpSecurity http) throws Exception {
    http
    .anonymous().disable()
    .requestMatchers().antMatchers("/admin/**")
    .and().authorizeRequests()
    .antMatchers("/admin/**").access("hasRole('ADMIN')")
    .and().exceptionHandling().accessDeniedHandler(new OAuth2AccessDeniedHandler());
}

}
