Spring Boot Security 整合 OAuth2 设计安全API接口服务在项目中我们通常使用授权码模式，也是

OAuth2概述 oauth2根据使用场景不同，分成了4种模式授权码模式（authorization code）简化模式（implicit）密码模式（resource owner password credentials）客户端模式（client credentials）在项目中我们通常使用授权码模式，也是四种模式中最复杂的，通常网站中经常出现的微博，qq第三方登录，都会采用这个形式。 Oauth2授权主要由两部分组成： Authorization server：认证服务 Resource server：资源服务在实际项目中以上两个服务可以在一个服务器上，也可以分开部署。下面结合spring boot来说明如何使用。

建表

客户端信息可以存储在内存、redis和数据库。在实际项目中通常使用redis和数据库存储。本文采用数据库。Spring 0Auth2 己经设计好了数据库的表，且不可变。

创建0Auth2数据库的脚本如下:

DROP TABLE IF EXISTS clientdetails; DROP TABLE IF EXISTS oauth_access_token; DROP TABLE IF EXISTS oauth_approvals; DROP TABLE IF EXISTS oauth_client_details; DROP TABLE IF EXISTS oauth_client_token; DROP TABLE IF EXISTS oauth_refresh_token;

CREATE TABLE clientdetails ( appId varchar(128) NOT NULL, resourceIds varchar(256) DEFAULT NULL, appSecret varchar(256) DEFAULT NULL, scope varchar(256) DEFAULT NULL, grantTypes varchar(256) DEFAULT NULL, redirectUrl varchar(256) DEFAULT NULL, authorities varchar(256) DEFAULT NULL, access_token_validity int(11) DEFAULT NULL, refresh_token_validity int(11) DEFAULT NULL, additionalInformation varchar(4096) DEFAULT NULL, autoApproveScopes varchar(256) DEFAULT NULL, PRIMARY KEY (appId) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE oauth_access_token ( token_id varchar(256) DEFAULT NULL, token blob, authentication_id varchar(128) NOT NULL, user_name varchar(256) DEFAULT NULL, client_id varchar(256) DEFAULT NULL, authentication blob, refresh_token varchar(256) DEFAULT NULL, PRIMARY KEY (authentication_id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE oauth_approvals ( userId varchar(256) DEFAULT NULL, clientId varchar(256) DEFAULT NULL, scope varchar(256) DEFAULT NULL, status varchar(10) DEFAULT NULL, expiresAt datetime DEFAULT NULL, lastModifiedAt datetime DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE oauth_client_details ( client_id varchar(128) NOT NULL, resource_ids varchar(256) DEFAULT NULL, client_secret varchar(256) DEFAULT NULL, scope varchar(256) DEFAULT NULL, authorized_grant_types varchar(256) DEFAULT NULL, web_server_redirect_uri varchar(256) DEFAULT NULL, authorities varchar(256) DEFAULT NULL, access_token_validity int(11) DEFAULT NULL, refresh_token_validity int(11) DEFAULT NULL, additional_information varchar(4096) DEFAULT NULL, autoapprove varchar(256) DEFAULT NULL, PRIMARY KEY (client_id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE oauth_client_token ( token_id varchar(256) DEFAULT NULL, token blob, authentication_id varchar(128) NOT NULL, user_name varchar(256) DEFAULT NULL, client_id varchar(256) DEFAULT NULL, PRIMARY KEY (authentication_id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS oauth_code; CREATE TABLE oauth_code ( code varchar(256) DEFAULT NULL, authentication blob ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE oauth_refresh_token ( token_id varchar(256) DEFAULT NULL, token blob, authentication blob ) ENGINE=InnoDB DEFAULT CHARSET=utf8; 为了测试方便，我们先插入一条客户端信息。

INSERT INTO oauth_client_details VALUES ('dev', '', 'dev', 'app', 'password,client_credentials,authorization_code,refresh_token', 'www.baidu.com', '', 3600, 3600, '{"country":"CN","country_code":"086"}', 'false'); 用户、权限、角色用到的表如下:

DROP TABLE IF EXISTS user; DROP TABLE IF EXISTS role; DROP TABLE IF EXISTS user_role; DROP TABLE IF EXISTS role_permission; DROP TABLE IF EXISTS permission;

CREATE TABLE user ( id bigint(11) NOT NULL AUTO_INCREMENT, username varchar(255) NOT NULL, password varchar(255) NOT NULL, PRIMARY KEY (id) ); CREATE TABLE role ( id bigint(11) NOT NULL AUTO_INCREMENT, name varchar(255) NOT NULL, PRIMARY KEY (id) ); CREATE TABLE user_role ( user_id bigint(11) NOT NULL, role_id bigint(11) NOT NULL ); CREATE TABLE role_permission ( role_id bigint(11) NOT NULL, permission_id bigint(11) NOT NULL ); CREATE TABLE permission ( id bigint(11) NOT NULL AUTO_INCREMENT, url varchar(255) NOT NULL, name varchar(255) NOT NULL, description varchar(255) NULL, pid bigint(11) NOT NULL, PRIMARY KEY (id) );

INSERT INTO user (id, username, password) VALUES (1,'user','e10adc3949ba59abbe56e057f20f883e'); INSERT INTO user (id, username , password) VALUES (2,'admin','e10adc3949ba59abbe56e057f20f883e'); INSERT INTO role (id, name) VALUES (1,'USER'); INSERT INTO role (id, name) VALUES (2,'ADMIN'); INSERT INTO permission (id, url, name, pid) VALUES (1,'/','',0); INSERT INTO permission (id, url, name, pid) VALUES (2,'/','',0); INSERT INTO user_role (user_id, role_id) VALUES (1, 1); INSERT INTO user_role (user_id, role_id) VALUES (2, 2); INSERT INTO role_permission (role_id, permission_id) VALUES (1, 1); INSERT INTO role_permission (role_id, permission_id) VALUES (2, 2); 项目结构

            return res;

}

} AuthorizationServerConfiguration 认证服务器配置

/**

/**
- 注入权限验证控制器来支持 password grant type */ @Autowired private AuthenticationManager authenticationManager;
/**
- 注入userDetailsService，开启refresh_token需要用到 */ @Autowired private MyUserDetailsService userDetailsService;
/**

/**

@Autowired private WebResponseExceptionTranslator webResponseExceptionTranslator;

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

@Override public void configure(AuthorizationServerSecurityConfigurer security) throws Exception { /** * 配置oauth2服务跨域 / CorsConfigurationSource source = new CorsConfigurationSource() { @Override public CorsConfiguration getCorsConfiguration(HttpServletRequest request) { CorsConfiguration corsConfiguration = new CorsConfiguration(); corsConfiguration.addAllowedHeader(""); corsConfiguration.addAllowedOrigin(request.getHeader( HttpHeaders.ORIGIN)); corsConfiguration.addAllowedMethod("*"); corsConfiguration.setAllowCredentials(true); corsConfiguration.setMaxAge(3600L); return corsConfiguration; } };
```
 security.tokenKeyAccess("permitAll()")
         .checkTokenAccess("permitAll()")
         .allowFormAuthenticationForClients()
         .addTokenEndpointAuthenticationFilter(new CorsFilter(source));
```
}

@Override public void configure(ClientDetailsServiceConfigurer clients) throws Exception { clients.jdbc(dataSource); }

@Override public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception { //开启密码授权类型 endpoints.authenticationManager(authenticationManager); //配置token存储方式 endpoints.tokenStore(tokenStore); //自定义登录或者鉴权失败时的返回信息 endpoints.exceptionTranslator(webResponseExceptionTranslator); //要使用refresh_token的话，需要额外配置userDetailsService endpoints.userDetailsService( userDetailsService );

}

} ResourceServerConfig 资源服务器配置

/**

/**
- 这里设置需要token验证的url
- 这些url可以在WebSecurityConfigurerAdapter中排查掉，
- 对于相同的url，如果二者都配置了验证

验证密码授权模式 [ 密码模式需要参数：username , password , grant_type , client_id , client_secret ]

请求token

curl -X POST -d "username=admin&password=123456&grant_type=password&client_id=dev&client_secret=dev" http://localhost:8080/oauth/token 返回

{ "access_token": "d94ec0aa-47ee-4578-b4a0-8cf47f0e8639", "token_type": "bearer", "refresh_token": "23503bc7-4494-4795-a047-98db75053374", "expires_in": 3475, "scope": "app" } 不携带token访问资源，

curl http://localhost:8080/hi?name=zhangsan 返回提示未授权

{ "error": "unauthorized", "error_description": "Full authentication is required to access this resource" } 携带token访问资源

curl http://localhost:8080/hi?name=zhangsan&access_token=164471f7-6fc6-4890-b5d2-eb43bda3328a 返回正确

hi , zhangsan 刷新token

curl -X POST -d 'grant_type=refresh_token&refresh_token=23503bc7-4494-4795-a047-98db75053374&client_id=dev&client_secret=dev' http://localhost:8080/oauth/token 返回

{ "access_token": "ef53eb01-eb9b-46d8-bd58-7a0f9f44e30b", "token_type": "bearer", "refresh_token": "23503bc7-4494-4795-a047-98db75053374", "expires_in": 3599, "scope": "app" } 客户端授权模式 [ 客户端模式需要参数：grant_type , client_id , client_secret ]

请求token

curl -X POST -d "grant_type=client_credentials&client_id=dev&client_secret=dev" http://localhost:8080/oauth/token 返回

{ "access_token": "a7be47b3-9dc8-473e-967a-c7267682dc66", "token_type": "bearer", "expires_in": 3564, "scope": "app" } 授权码模式获取code

浏览器中访问如下地址：

http://localhost:8080/oauth/authorize?response_type=code&client_id=dev&redirect_uri=http://www.baidu.com 跳转到登录页面，输入账号和密码进行认证：

认证后会跳转到授权确认页面（oauth_client_details 表中 “autoapprove” 字段设置为true 时，不会出授权确认页面）：

通过code换token

curl -X POST -d "grant_type=authorization_code&code=qS03iu&client_id=dev&client_secret=dev&redirect_uri=http://www.baidu.com" http://localhost:8080/oauth/token

{ "access_token": "90a246fa-a9ee-4117-8401-ca9c869c5be9", "token_type": "bearer", "refresh_token": "23503bc7-4494-4795-a047-98db75053374", "expires_in": 3319, "scope": "app" }
