1、OAuth2.0信息存储方式
在前面文章中我们学习了OAuth2的一些基本概念，对OAuth2有了基本的认识，也对OAuth2.0的几种授权模式进行了实践，比如授权码模式
在前面的学习中，我们配置客户端信息，一般会如下配置，如果有多个客户端的话，就复制一遍，修改一些参数，很显然，这种在生产环境是不适应的，所以Spring Security OAuth2是有提供几种存储方式的，默认是基于内存存储
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients
// 使用内存存储
.inMemory()
//标记客户端id
.withClient(CLIENT_ID)
//客户端安全码
.secret(SECRET_CHAR_SEQUENCE)
//为true 直接自动授权成功返回code
.autoApprove(true)
.redirectUris("http://127.0.0.1:8084/cms/login") //重定向uri
//允许授权范围
.scopes(ALL)
//token 时间秒
.accessTokenValiditySeconds(ACCESS_TOKEN_VALIDITY_SECONDS)
//刷新token 时间 秒
.refreshTokenValiditySeconds(FREFRESH_TOKEN_VALIDITY_SECONDS)
//允许授权类型
.authorizedGrantTypes(GRANT_TYPE_PASSWORD , AUTHORIZATION_CODE , REFRESH_TOKEN , IMPLICIT);
}
对于token存储一遍使用内存存储
@Bean
public TokenStore memoryTokenStore() {
// 最基本的InMemoryTokenStore生成token
return new InMemoryTokenStore();
}
IDEA中，Ctrl+Alt+B，可以看到TokenStore的实现，有如下几种：
ok，其实对于token存储有如上方式，对于其它比如授权码code等的存储也基本如上几种，分别进行介绍：
- InMemoryTokenStore，默认存储，保存在内存
- JdbcTokenStore，access_token存储在数据库
- JwtTokenStore，JWT这种方式比较特殊，这是一种无状态方式的存储，不进行内存、数据库存储，只是JWT中携带全面的用户信息，保存在jwt中携带过去校验就可以
- RedisTokenStore，将 access_token 存到 redis 中。
- JwkTokenStore，将 access_token 保存到 JSON Web Key。
2、数据表schema脚本
ok，有了前面的了解之后，现在要实现客户端配置信息，access_token等等信息的数据库存储要怎么实现？
要数据库存储，肯定要先建表，当然不用自己设计，去官方github拿就可以。schema脚本：官方Spring-security-oauth2提供的所有脚本：链接，官方脚本是HSQL数据库，所以我们改成mysql版，其中oauth_client_details 用于存储客户端配置信息，oauth_code存储授权码，oauth_access_token存储access_token
-- used in tests that use MYSQL
CREATE TABLE oauth_client_details (
client_id VARCHAR(128) PRIMARY KEY,
resource_ids VARCHAR(128),
client_secret VARCHAR(128),
scope VARCHAR(128),
authorized_grant_types VARCHAR(128),
web_server_redirect_uri VARCHAR(128),
authorities VARCHAR(128),
access_token_validity INTEGER,
refresh_token_validity INTEGER,
additional_information VARCHAR(4096),
autoapprove VARCHAR(128)
);
CREATE TABLE oauth_client_token (
token_id VARCHAR(128),
token BLOB,
authentication_id VARCHAR(128) PRIMARY KEY,
user_name VARCHAR(128),
client_id VARCHAR(128)
);
CREATE TABLE oauth_access_token (
token_id VARCHAR(128),
token BLOB,
authentication_id VARCHAR(128) PRIMARY KEY,
user_name VARCHAR(128),
client_id VARCHAR(128),
authentication BLOB,
refresh_token VARCHAR(128)
);
CREATE TABLE oauth_refresh_token (
token_id VARCHAR(128),
token BLOB,
authentication BLOB
);
CREATE TABLE oauth_code (
CODE VARCHAR(128), authentication BLOB
);
CREATE TABLE oauth_approvals (
userId VARCHAR(128),
clientId VARCHAR(128),
scope VARCHAR(128),
STATUS VARCHAR(10),
expiresAt TIMESTAMP,
lastModifiedAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
-- customized oauth_client_details table
CREATE TABLE ClientDetails (
appId VARCHAR(128) PRIMARY KEY,
resourceIds VARCHAR(128),
appSecret VARCHAR(128),
scope VARCHAR(128),
grantTypes VARCHAR(128),
redirectUrl VARCHAR(128),
authorities VARCHAR(128),
access_token_validity INTEGER,
refresh_token_validity INTEGER,
additionalInformation VARCHAR(4096),
autoApproveScopes VARCHAR(128)
);
要进行登录验证，也可以设计一张用户数据业务表：
# 用户表
CREATE TABLE USER (
id INT(11) NOT NULL AUTO_INCREMENT,
email VARCHAR(255),
PASSWORD VARCHAR(255) NOT NULL,
phone VARCHAR(255),
username VARCHAR(255) NOT NULL UNIQUE,
last_login_time DATETIME ,
PRIMARY KEY (id)
)
INSERT INTO USER (email,PASSWORD,phone,username,last_login_time) VALUES ('[email protected]','11','15522288822','admin',SYSDATE());
3、SpringBoot环境搭建
- IntelliJ IDEA
- Maven3.+版本
新建SpringBoot Initializer项目，可以命名oauth2-jdbc-store
主要加入如下配置：
org.springframework.boot
spring-boot-starter-web
org.springframework.cloud
spring-cloud-starter-oauth2
org.springframework.cloud
spring-cloud-starter-security
数据库相关maven配置，orm框架使用mybatis
org.mybatis.spring.boot
mybatis-spring-boot-starter
2.1.1
mysql
mysql-connector-java
5.1.27
runtime
lombok也可以加进来，自行配置：
org.projectlombok
lombok
1.16.10
数据源配置：
spring:
datasource:
url: jdbc:mysql://127.0.0.1::3306/jeeplatform?autoReconnect=true&useUnicode=true&characterEncoding=utf8&characterSetResults=utf8&useSSL=false
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
Mybatis配置类：
package com.example.springboot.oauth2.config;
import org.mybatis.spring.annotation.MapperScan;
import org.mybatis.spring.boot.autoconfigure.ConfigurationCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
/**
*
* Mybatis配置
*
*
*
* @author mazq
* 修改记录
* 修改后版本: 修改人： 修改日期: 2020/06/15 15:33 修改内容:
*
*/
@Configuration
@EnableTransactionManagement
@MapperScan(basePackages = {"com.example.springboot.oauth2.mapper"})
public class MybatisConfig {
/**
* 配置支持驼峰命名和大小写自动转换
* @Author mazq
* @Date 2020/06/15 15:34
* @Param []
*/
@Bean
public ConfigurationCustomizer configurationCustomizer(){
return new ConfigurationCustomizer(){
@Override
public void customize(org.apache.ibatis.session.Configuration configuration) {
configuration.setMapUnderscoreToCamelCase(true);
}
};
}
}
4、OAuth2.0配置类实现
4.1 客户端信息
先将客户端配置信息存储到数据表：
insert into `oauth_client_details` (`client_id`, `resource_ids`, `client_secret`, `scope`, `authorized_grant_types`, `web_server_redirect_uri`, `authorities`, `access_token_validity`, `refresh_token_validity`, `additional_information`, `autoapprove`) values('cms',NULL,'{noop}secret','all','authorization_code','http://localhost:8084/cms/login',NULL,'60','60',NULL,'true');
insert into `oauth_client_details` (`client_id`, `resource_ids`, `client_secret`, `scope`, `authorized_grant_types`, `web_server_redirect_uri`, `authorities`, `access_token_validity`, `refresh_token_validity`, `additional_information`, `autoapprove`) values('oa',NULL,'{noop}secret','all','authorization_code','http://localhost:8082/oa/login',NULL,'60','60',NULL,'true');
OAuth2.0配置类加上@EnableAuthorizationServer，实现AuthorizationServerConfigurerAdapter抽象类
@Configuration
@EnableAuthorizationServer
public class OAuth2Config extends AuthorizationServerConfigurerAdapter {
...
}
配置数据从oauth_client_details表读取来存储，先加上如下配置
@Autowired
@Qualifier("dataSource")
private DataSource dataSource;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
// 配置数据从oauth_client_details表读取来存储
clients.withClientDetails(clientDetailsService());
}
@Bean
public ClientDetailsService clientDetailsService() {
Assert.state(dataSource != null, "DataSource must be provided");
return new JdbcClientDetailsService(dataSource);
}
启动过程可能出现ClientDetailsService 不能被重写，可以加上如下配置：
spring:
main:
allow-bean-definition-overriding: true
4.2 授权码和token配置
授权码和token同样配置
@Bean
public AuthorizationCodeServices authorizationCodeServices() {
Assert.state(dataSource != null, "DataSource must be provided");
return new JdbcAuthorizationCodeServices(dataSource);
}
@Bean
public TokenStore jdbcTokenStore() {
Assert.state(dataSource != null, "DataSource must be provided");
return new JdbcTokenStore(dataSource);
}
4.3 TokenStoreUserApprovalHandler
自定义TokenStoreUserApprovalHandler：
package com.example.springboot.oauth2.component;
import com.example.springboot.oauth2.entity.dto.OauthClientDetailsDto;
import com.example.springboot.oauth2.service.OAuthService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.oauth2.provider.AuthorizationRequest;
import org.springframework.security.oauth2.provider.approval.TokenStoreUserApprovalHandler;
/**
*
* 自定义TokenStoreUserApprovalHandler
*
*
*
* @author mazq
* 修改记录
* 修改后版本: 修改人： 修改日期: 2020/06/15 14:48 修改内容:
*
*/
//@Component
public class JdbcTokenStoreUserApprovalHandler extends TokenStoreUserApprovalHandler {
Logger LOG = LoggerFactory.getLogger(JdbcTokenStoreUserApprovalHandler.class);
@Autowired
OAuthService oAuthService;
@Override
public boolean isApproved(AuthorizationRequest authorizationRequest, Authentication userAuthentication) {
if (super.isApproved(authorizationRequest, userAuthentication)) {
return true;
}
if (!userAuthentication.isAuthenticated()) {
return false;
}
String clientId = authorizationRequest.getClientId();
LOG.info("clientId:[{}]",clientId);
OauthClientDetailsDto clientDetails = oAuthService.loadOauthClientDetails(clientId);
return clientDetails != null;
}
}
OauthClientDetailsDto类：
package com.example.springboot.oauth2.entity.dto;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import java.io.Serializable;
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class OauthClientDetailsDto implements Serializable {
private String clientId;
private String resourceIds;
/**
* Encrypted
*/
private String clientSecret;
/**
* Available values: read,write
*/
private String scope;
/**
* grant types include
* "authorization_code", "password", "assertion", and "refresh_token".
* Default value is "authorization_code,refresh_token".
*/
private String authorizedGrantTypes = "authorization_code,refresh_token";
/**
* The re-direct URI(s) established during registration (optional, comma separated).
*/
private String webServerRedirectUri;
/**
* Authorities that are granted to the client (comma-separated). Distinct from the authorities
* granted to the user on behalf of whom the client is acting.
*
* For example: ROLE_USER
*/
private String authorities;
/**
* The access token validity period in seconds (optional).
* If unspecified a global default will be applied by the token services.
*/
private Integer accessTokenValidity;
/**
* The refresh token validity period in seconds (optional).
* If unspecified a global default will be applied by the token services.
*/
private Integer refreshTokenValidity;
// optional
private String additionalInformation;
/**
* Value is 'true' or 'false', default 'false'
*/
private String autoApprove;
}
加上UserApprovalHandler bean
@Bean
public OAuth2RequestFactory oAuth2RequestFactory() {
return new DefaultOAuth2RequestFactory(clientDetailsService());
}
@Bean
public UserApprovalHandler userApprovalHandler() {
JdbcTokenStoreUserApprovalHandler approvalHandler = new JdbcTokenStoreUserApprovalHandler();
approvalHandler.setTokenStore(jdbcTokenStore());
approvalHandler.setClientDetailsService(clientDetailsService());
approvalHandler.setRequestFactory(oAuth2RequestFactory());
return approvalHandler;
}
配置类配置启动：
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.tokenStore(jdbcTokenStore()).authenticationManager(authenticationManager)
//自定义AccessToken
//.accessTokenConverter(accessTokenConverter)
//设置userDetailsService
.userDetailsService(userDetailsService)
//授权码储存
.authorizationCodeServices(authorizationCodeServices())
//设置userApprovalHandler
.userApprovalHandler(userApprovalHandler())
//设置tokenServices
//.tokenServices(tokenServices())
//支持获取token方式
.allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST,HttpMethod.PUT,HttpMethod.DELETE,HttpMethod.OPTIONS)
//刷新token
.reuseRefreshTokens(true);
}

import java.util.Arrays;
import java.util.List;
@Service("userDetailService")
public class UserDetailServiceImpl implements UserDetailsService {
Logger LOG = LoggerFactory.getLogger(UserDetailServiceImpl.class);
@Autowired
UserDao userDao;
@Override
@Transactional(propagation = Propagation.SUPPORTS,rollbackFor = Exception.class,readOnly = true)
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userDao.findByUsername(username);
if(user == null){
//LOG.info("登录用户[{}]没注册!",username);
throw new UsernameNotFoundException("登录用户["+username + "]没注册!");
}
return new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(), getAuthority());
}
private List getAuthority() {
return Arrays.asList(new SimpleGrantedAuthority("ROLE_ADMIN"));
}
}
5、SpringSecurity配置类

*/
@Configuration
@EnableWebSecurity
@Order(1)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Resource(name = "userDetailService")
private UserDetailsService userDetailsService;
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception { //auth.inMemoryAuthentication()
auth.userDetailsService(userDetailsService)
.passwordEncoder(new CustomPasswordEncoder());
auth.parentAuthenticationManager(authenticationManagerBean());
}
@Override
public void configure(WebSecurity web) throws Exception {
//解决静态资源被拦截的问题
web.ignoring().antMatchers("/asserts/**");
web.ignoring().antMatchers("/favicon.ico");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http // 配置登录页并允许访问
.formLogin().permitAll()
// 配置Basic登录
//.and().httpBasic()
// 配置登出页面
.and().logout().logoutUrl("/logout").logoutSuccessUrl("/")
.and().authorizeRequests().antMatchers("/oauth/**", "/login/**", "/logout/**").permitAll()
// 其余所有请求全部需要鉴权认证
.anyRequest().authenticated()
// 关闭跨域保护;
.and().csrf().disable();
}
}
6、OAuth2.0授权功能简单测试
访问授权链接，在浏览器访问就可以，授权码模式response_type参数传code：
http://localhost:8888/oauth/authorize?client_id=cms&client_secret=secret&response_type=code
因为没登录，所以会返回SpringSecurity的默认登录页面，具体代码是 http .formLogin().permitAll();，如果要弹窗登录的，可以配置http.httpBasic();，这种配置是没有登录页面的，自定义登录页面可以这样配置http.formLogin().loginPage("/login").permitAll()
如图，输入SpringSecurity配置的数据库密码
登录成功，返回redirect_uri，拿到授权码
重定向回redirect_uri，http://localhost:8084/cms/login?code=???
查询数据库SELECT * FROM oauth_code; ， 授权码code保存成功：
配置一下请求头的授权参数，用Basic Auth方式，username即client_id，password即client_secret
拿到授权码之后去获取token，本教程使用授权码方式
查询数据库SELECT * FROM oauth_access_token;，token是保存成功的：
