oauth2需要完全认证才能访问此资源错误

Question

即使进行了所有配置，我仍然收到401错误。当我请求访问令牌时，它的说法是“需要完全认证才能访问此资源。”

我使用邮递员完成了oauth config和im，其中我已经通过了用户名，密码，grantype。以及客户ID和机密。

oauth2配置......

@Configuration
public class OAuthserConfig extends WebSecurityConfigurerAdapter implements AuthorizationServerConfigurer 
{
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception 
    {
        return super.authenticationManagerBean();
    }

    @Autowired
    AuthenticationManager authenticationManager; 

    PasswordEncoder passwordencoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();

    @Override public void configure(AuthorizationServerSecurityConfigurer security) throws Exception 
    { 
        // TODO Auto-generated method stub    
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception 
    {
        clients.inMemory()
               .withClient("abc")
               .secret(passwordencoder.encode("secret"))
               .scopes("READ","WRITE")
               .authorizedGrantTypes("password","authorization code");      
    }

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

用户配置...

@Configuration
public class UserConfig extends GlobalAuthenticationConfigurerAdapter 
{
    PasswordEncoder passwordencoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();

    @Override
    public void init(AuthenticationManagerBuilder auth) throws Exception 
    {       
        auth.inMemoryAuthentication().withUser("tj")
            .password(passwordencoder.encode("tj123"))
            .roles("USER","ADMIN","MANAGER")
            .authorities("CAN_READ","CAN_WRITE","CAN_DELETE");
    }   
}
