Spring Boot OAuth：不支持的授权类型

如果您使用的是 grant_type =“ password” ，则必须：

在自己的

WebSecurityConfigurerAdapter

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

注入

AuthorizationServerConfigurerAdapter

@Autowiredprivate AuthenticationManager authenticationManager;

在

configure(AuthorizationServerEndpointsConfigurer endpoints)

@Overridepublic void configure(AuthorizationServerEndpointsConfigurer endpoints) {   endpoints.authenticationManager(authenticationManager);}

完整示例：

@Configurationpublic class WebSecurityConfig extends WebSecurityConfigurerAdapter {    @Override    @Bean    public AuthenticationManager authenticationManagerBean() throws Exception {        return super.authenticationManagerBean();    }    @Bean    @Override    protected UserDetailsService userDetailsService(){        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();        manager.createUser(User.withUsername("a").password("123456").authorities("USER").build());        return manager;    }}@Configuration@EnableAuthorizationServerpublic class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {    private AuthenticationManager authenticationManager;    @Autowired    public AuthorizationServerConfig(AuthenticationManager authenticationManager) {        this.authenticationManager = authenticationManager;    }    @Override    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {        endpoints.authenticationManager(authenticationManager);    }    @Override    public void configure(AuthorizationServerSecurityConfigurer security) {         security.tokenKeyAccess("permitAll()")    .checkTokenAccess("isAuthenticated()")       .allowFormAuthenticationForClients();    }    @Override        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {        clients.inMemory()     .withClient("CLIEN_ID").secret("CLIENT_SECRET")     .authorizedGrantTypes("password", "refresh_token")     .authorities("CLIENT")     .scopes("read");    }}

测试：

curl -i -X POST -d "username=a&password=123456&grant_type=password&client_id=CLIENT_ID&client_secret=CLIENT_SECRET" http://localhost:8080/oauth/token
