Java Spring启动OAuth，在JwtTokenStore类中获取空指针异常

我第一次将OAuth2实现到Spring引导API中

我已经设法从API中获取了一个访问令牌，但是当我试图使用它来调用API时，我得到了以下错误：

java.lang.NullPointerException: null

这是配置OAuthServer的类

@Configuration
public class OAuth2ServerConfiguration {

    private static final String RESOURCE_ID = "myapi";

    @Configuration
    @EnableResourceServer
    protected static class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {
        @Autowired
        private JwtAccessTokenConverter jwtAccessTokenConverter;

        @Override
        public void configure(ResourceServerSecurityConfigurer resources) {
            // @formatter:off
            resources
                    .resourceId(RESOURCE_ID).tokenStore(new JwtTokenStore(jwtAccessTokenConverter));
            // @formatter:on
        }

        @Override
        public void configure(HttpSecurity http) throws Exception {
            // @formatter:off
            http
                    .csrf().disable()
                    .authorizeRequests()
                    .antMatchers("/api/**").authenticated();
            // @formatter:on
        }
    }

    @Configuration
    @EnableAuthorizationServer
    protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
        @Autowired
        private JwtAccessTokenConverter jwtAccessTokenConverter;

        private TokenStore tokenStore = new JwtTokenStore(jwtAccessTokenConverter);

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

        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            // @formatter:off
            endpoints
                    .tokenStore(tokenStore)
                    .authenticationManager(authenticationManager)
                    .accessTokenConverter(jwtAccessTokenConverter);
            // @formatter:on
        }

        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            // @formatter:off
            clients
                    .inMemory()
                    .withClient("12345")
                    .authorizedGrantTypes("password", "refresh_token")
                    .authorities("USER")
                    .scopes("read", "write")
                    .resourceIds(RESOURCE_ID)
                    .secret("54321")
                    .accessTokenValiditySeconds(2592000) // 30 days
                    .refreshTokenValiditySeconds(3888000); // 15 days more than access token
            // @formatter:on
        }
    }

}

我在生成错误的行上放置了一个断点，在我看来，TokenEnhancer是null，我猜这就是导致问题的原因，但我不明白为什么它是null？看看文档，TokenEnhancer只是一个TokenConverter，我在这个类中将它定义为一个Bean

@Configuration
@EnableWebSecurity
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private Environment env;

    @Autowired
    private CustomUserDetailsService userDetailsService;

    @Autowired
    private AccountAuthenticationProvider accountAuthenticationProvider;

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

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

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

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        final JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
        jwtAccessTokenConverter.setSigningKey(env.getProperty("jwt.secret"));
        return jwtAccessTokenConverter;
    }

}

我设法弄明白了这一点。我需要将令牌存储设置为JdbcTokenStore（），现在它可以正常工作了。下面是我在数据库中用于oauth方面的数据库结构

DROP TABLE IF EXISTS `oauth_access_token`;
CREATE TABLE `oauth_access_token` (
  `token_id` varchar(255) DEFAULT NULL,
  `token` mediumblob,
  `authentication_id` varchar(255) NOT NULL,
  `user_name` varchar(255) DEFAULT NULL,
  `client_id` varchar(255) DEFAULT NULL,
  `authentication` mediumblob,
  `refresh_token` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`authentication_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

DROP TABLE IF EXISTS `oauth_approvals`;
CREATE TABLE `oauth_approvals` (
  `userId` varchar(255) DEFAULT NULL,
  `clientId` varchar(255) DEFAULT NULL,
  `scope` varchar(255) DEFAULT NULL,
  `status` varchar(10) DEFAULT NULL,
  `expiresAt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `lastModifiedAt` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00'
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

DROP TABLE IF EXISTS `oauth_client_details`;
CREATE TABLE `oauth_client_details` (
  `client_id` varchar(255) NOT NULL,
  `resource_ids` varchar(255) DEFAULT NULL,
  `client_secret` varchar(255) DEFAULT NULL,
  `scope` varchar(255) DEFAULT NULL,
  `authorized_grant_types` varchar(255) DEFAULT NULL,
  `web_server_redirect_uri` varchar(255) DEFAULT NULL,
  `authorities` varchar(255) DEFAULT NULL,
  `access_token_validity` int(11) DEFAULT NULL,
  `refresh_token_validity` int(11) DEFAULT NULL,
  `additional_information` varchar(4096) DEFAULT NULL,
  `autoapprove` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`client_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

DROP TABLE IF EXISTS `oauth_client_token`;
CREATE TABLE `oauth_client_token` (
  `token_id` varchar(255) DEFAULT NULL,
  `token` mediumblob,
  `authentication_id` varchar(255) NOT NULL,
  `user_name` varchar(255) DEFAULT NULL,
  `client_id` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`authentication_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

DROP TABLE IF EXISTS `oauth_code`;
CREATE TABLE `oauth_code` (
  `code` varchar(255) DEFAULT NULL,
  `authentication` mediumblob
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

DROP TABLE IF EXISTS `oauth_refresh_token`;
CREATE TABLE `oauth_refresh_token` (
  `token_id` varchar(255) DEFAULT NULL,
  `token` mediumblob,
  `authentication` mediumblob
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

例如，在我的代码中，我引用了TokenStore

private TokenStore tokenStore = new JwtTokenStore(jwtAccessTokenConverter);

及

我创建了一个令牌存储bean

@Autowired
    DataSource dataSource;

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

然后将其用作令牌存储

@Autowired
private TokenStore tokenStore;

及

@Autowired
    DataSource dataSource;

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

@Autowired
private TokenStore tokenStore;

public void configure(ResourceServerSecurityConfigurer resources) {
            resources.resourceId(RESOURCE_ID).tokenStore(tokenStore);
        }
