# OAuth2.0數據庫JDBC存儲客戶端的示例
## 引言
OAuth2.0作為當前主流的授權框架,廣泛應用于各類Web應用和移動應用中。在實際開發中,我們通常需要將客戶端信息存儲在數據庫中以便動態管理。本文將詳細介紹如何通過JDBC方式在關系型數據庫中存儲OAuth2.0客戶端信息,并提供完整的代碼示例。
---
## 一、OAuth2.0客戶端存儲基礎
### 1.1 客戶端核心字段
根據RFC 6749標準,OAuth2.0客戶端至少需要包含以下信息:
- `client_id`: 客戶端唯一標識
- `client_secret`: 客戶端密鑰
- `scope`: 授權范圍
- `authorized_grant_types`: 允許的授權類型
- `redirect_uri`: 回調地址
- `access_token_validity`: 訪問令牌有效期
- `refresh_token_validity`: 刷新令牌有效期
### 1.2 數據庫表設計
推薦的表結構設計:
```sql
CREATE TABLE oauth_client_details (
client_id VARCHAR(256) PRIMARY KEY,
client_secret VARCHAR(256) NOT NULL,
scope VARCHAR(256),
authorized_grant_types VARCHAR(256),
web_server_redirect_uri VARCHAR(256),
access_token_validity INTEGER,
refresh_token_validity INTEGER,
additional_information VARCHAR(4096)
);
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>2.5.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
spring:
datasource:
url: jdbc:mysql://localhost:3306/oauth_db
username: root
password: password
driver-class-name: com.mysql.cj.jdbc.Driver
public class CustomJdbcClientDetailsService extends JdbcClientDetailsService {
private static final String CLIENT_FIELDS_FOR_UPDATE =
"client_secret, scope, authorized_grant_types, " +
"web_server_redirect_uri, access_token_validity, " +
"refresh_token_validity, additional_information";
public CustomJdbcClientDetailsService(DataSource dataSource) {
super(dataSource);
setSelectClientDetailsSql(
"select client_id, " + CLIENT_FIELDS_FOR_UPDATE +
" from oauth_client_details where client_id = ?");
}
}
@Override
public ClientDetails loadClientByClientId(String clientId) {
try {
return jdbcTemplate.queryForObject(
selectClientDetailsSql,
new ClientDetailsRowMapper(),
clientId);
} catch (EmptyResultDataAccessException e) {
throw new NoSuchClientException(...);
}
}
@Configuration
@EnableAuthorizationServer
public class AuthServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private DataSource dataSource;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.jdbc(dataSource)
.withClient("sampleClientId")
.secret(passwordEncoder().encode("secret"))
.scopes("read", "write")
.authorizedGrantTypes("authorization_code", "refresh_token")
.redirectUris("http://localhost:8080/callback");
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/oauth/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin().permitAll();
}
}
@RestController
@RequestMapping("/api/clients")
public class ClientRegistrationController {
@Autowired
private JdbcClientDetailsService clientDetailsService;
@PostMapping
public ResponseEntity<?> registerClient(@RequestBody ClientDetailsDTO dto) {
BaseClientDetails client = new BaseClientDetails(
dto.getClientId(),
null,
dto.getScope(),
dto.getGrantTypes(),
null,
dto.getRedirectUri()
);
client.setClientSecret(passwordEncoder.encode(dto.getSecret()));
clientDetailsService.addClientDetails(client);
return ResponseEntity.created(...).build();
}
}
@GetMapping("/{clientId}")
public ClientDetails getClient(@PathVariable String clientId) {
return clientDetailsService.loadClientByClientId(clientId);
}
curl -X POST \
http://localhost:8080/oauth/token \
-H 'Authorization: Basic c2FtcGxlQ2xpZW50SWQ6c2VjcmV0' \
-d 'grant_type=client_credentials'
{
"access_token": "a1b2c3d4-e5f6-7890",
"token_type": "bearer",
"expires_in": 3599,
"scope": "read write"
}
通過JDBC存儲OAuth2.0客戶端信息,我們實現了客戶端的動態管理和持久化存儲。這種方案既保持了靈活性,又能滿足企業級應用的安全需求。讀者可以根據實際業務場景,在此基礎上進行擴展和優化。
