### 问题： Spring Security – There is no PasswordEncoder mapped for the id “null” ###

解决方法一：  
问题解决：[https://blog.csdn.net/Hello\_World\_QWP/article/details/81811462][https_blog.csdn.net_Hello_World_QWP_article_details_81811462]

解决方法二：  
因为5.x版本新增了多种密码加密方式，必须指定一种，比如这样解决

@Bean
     public static NoOpPasswordEncoder passwordEncoder() {
       return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();
     }

### 问题2：调用接口/com-oauth/oauth/check\_token失败 ###

返回错误码：

{
      "timestamp": "2019-07-10T02:57:43.818+0000",
      "status": 403,
      "error": "Forbidden",
      "message": "Forbidden",
      "path": "/com-oauth/oauth/check_token"
    }

解决方法一：  
设置 security.tokenKeyAccess(“permitAll()”).checkTokenAccess(“permitAll()”);

@Configuration
    @EnableAuthorizationServer
    public class OAuth2AuthorizationServer extends AuthorizationServerConfigurerAdapter {
    
        @Override
        public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
            super.configure(security);
            security.tokenKeyAccess("permitAll()").checkTokenAccess("permitAll()");
        }
    }

### 问题3： 在使用密码模式时，抛出异常：o.s.s.o.provider.endpoint.TokenEndpoint : Handling error: UnsupportedGrantTypeException, Unsupported grant type: password ###

解决方法：配置AuthenticationManager

@Configuration
    @EnableAuthorizationServer
    public class OAuth2AuthorizationServer extends AuthorizationServerConfigurerAdapter {
    
    
       // 用户认证
       @Autowired
       private AuthenticationManager authenticationManager;
    
       @Override
       public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
           super.configure(endpoints);
           // 密码模式必须有这个参数
           endpoints.authenticationManager(authenticationManager);
       }
    }

### 问题4：Field authenticationManager in cn.springcloud.book.OAuthConfiguration required a bean of type ‘org.springframework.security.authentication.AuthenticationManager’ that could not be found ###

解决方法：  
集成WebSecurityConfigurerAdapter 类，并重写方法authenticationManager()，使用 @Bean注解标记

@ComponentScan
    @Configuration
    public class MyWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
    
        @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
        @Override
        protected AuthenticationManager authenticationManager() throws Exception {
            return super.authenticationManager();
        }
    }

### 问题5： 在passwod模式下，执行刷新token时，抛出异常Handling error: IllegalStateException, UserDetailsService is required. ###

执行以下命令，抛出异常Handling error: IllegalStateException, UserDetailsService is required

curl -i -X POST -u 'clientapp2:112233'  http://10.216.33.211:10808/com-oauth/oauth/token -H "accept: application/json" -d 'grant_type=refresh_token&refresh_token=b610dfa9-2ee4-4214-bc57-f6b2937d4b27'

解决方法：  
在AuthorizationServerConfigurerAdapter 中配置UserDetailsService对象

@Configuration
    @EnableAuthorizationServer
    public class OAuth2AuthorizationServer extends AuthorizationServerConfigurerAdapter {
    
        @Autowired
        private MyUserDetailsService myUserDetailsService;
    
        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            // 执行token刷新需要带上此参数
            endpoints.userDetailsService(myUserDetailsService);
        }
    }

### 问题6：不支持form表单提交 ###

执行命令：

curl -X POST "http://10.216.33.211:10808/com-oauth/oauth/token" -d "grant_type=client_credentials&scope=read_contacts&client_id=clientapp&client_secret=112233"

返回错误：

{"timestamp":"2019-07-11T02:27:29.962+0000","status":401,"error":"Unauthorized","message":"Unauthorized","path":"/com-oauth/oauth/token"}

解决方法：  
支持Form表达提交： security.allowFormAuthenticationForClients();

执行命令：

curl -X POST "http://10.216.33.211:10808/com-oauth/oauth/token" -d "grant_type=client_credentials&scope=read_contacts&client_id=clientapp&client_secret=112233"

返回正常结果：

{"access_token":"35ae4576-f7b3-480e-aeff-eee7ea2ce803","token_type":"bearer","refresh_token":"0493963a-22f5-4cff-8b50-3cc5da3577a6","expires_in":197,"scope":"read_contacts"}
