Spring Oauth2 授权服务器

我设置如下 Spring 配置：

@EnableAuthorizationServer
@EnableWebSecurity
@Configuration
public class Oauth2Provider extends WebSecurityConfigurerAdapter implements
        AuthorizationServerConfigurer {

    /*
     * @Autowired private TokenStore tokenStore;
     */

    @Configuration
    protected static class AuthenticationConfiguration extends
            GlobalAuthenticationConfigurerAdapter {

        @Override
        public void init(AuthenticationManagerBuilder auth) throws Exception {
            auth.inMemoryAuthentication().withUser("user").password("password")
                    .roles("USER").and().withUser("admin").password("password")
                    .roles("USER", "ADMIN");
        }

    }

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

    }

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

        // TODO Auto-generated method stub
        clients.inMemory()
                .withClient("my-trusted-client")
                .authorizedGrantTypes("password", "authorization_code", "refresh_token", "implicit")
                .authorities("ROLE_CLIENT", "ROLE_TRUSTED_CLIENT", "ROLE_ANONYMOUS")
                .scopes("read", "write", "trust")
                .secret("secret")
                .accessTokenValiditySeconds(60);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints)
            throws Exception {
        // TODO Auto-generated method stub

    }

}  

Maven 设置如下：

<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
    <version>2.0.5.RELEASE</version>
</dependency>

我访问：http://localhost:8080/oauth/token http://localhost:8080/oauth/token有效载荷 grant_type=密码&密码=密码&用户名=用户&范围=读取&client_id=我的可信客户端&client_secret=秘密

但我收到以下错误：

{
error: "unsupported_grant_type"
error_description: "Unsupported grant type: password"
}

要使用密码授予，您需要向授权服务器提供身份验证管理器（在示例中带有 TODO 的空方法中），以便它可以对用户进行身份验证。如果它是 Spring Boot 应用程序，那么总会有一个AuthenticationManager可以成为@Autowired.
