基于springSecurity的双token机制(accesToken,refreshToken)以及如何刷新token
在Spring Security中实现双token机制,即访问令牌(access token)和刷新令牌(refresh token),通常用于身份验证和访问资源。访问令牌在设定的时间后过期,刷新令牌可以被用来获取新的访问令牌。
以下是实现双token机制的步骤和示例代码:
- 配置Spring Security,使其支持OAuth2登录。
- 创建一个自定义的TokenStore,用于存储生成的token。
- 在登录成功后,生成访问令牌(access token)和刷新令牌(refresh token),并存储它们。
- 实现Token Endpoint,允许客户端使用刷新令牌来获取新的访问令牌。
示例代码:
@Configuration
@EnableAuthorizationServer
public class AuthServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private TokenStore tokenStore;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("client")
.secret("secret")
.authorizedGrantTypes("refresh_token", "password")
.scopes("read", "write")
.accessTokenValiditySeconds(15); // 访问令牌15秒后过期
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
TokenEnhancer tokenEnhancer = new CustomTokenEnhancer();
endpoints
.tokenStore(tokenStore)
.authenticationManager(authenticationManager)
.userDetailsService(userDetailsService)
.tokenEnhancer(tokenEnhancer)
.reuseRefreshTokens(false)
.exceptionTranslator(new CustomWebResponseExceptionTranslator());
}
}
@RestController
@RequestMapping("/api/token")
public class CustomTokenController {
@Autowired
private TokenStore tokenStore;
@PostMapping("/refresh")
public ResponseEntity<?> refreshToken(Authentication authentication) {
OAuth2AccessToken existingAccessToken = tokenStore.getAccessToken(authentication);
OAuth2RefreshToken refreshToken = existingAccessToken.getRefreshToken();
Token token = tokenStore.readRefreshToken(refreshToken.getValue());
if (token == null) {
return new ResponseEntity<>("Invalid refresh token", HttpStatus.BAD_REQUEST
