Spring Security OAuth2提供了默认的token生成方式,但有时我们需要自定义token的信息,例如添加一些自定义的字段,或修改过期时间等。下面是如何实现自定义token信息的攻略。
1. 自定义Token
我们可以通过实现TokenEnhancer
接口来自定义token信息。例如,在JWT token中我们可以添加自定义的claims信息。
@Component
public class CustomTokenEnhancer implements TokenEnhancer {
@Override
public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(Map.of("custom_field", "custom_value"));
return accessToken;
}
}
2. 配置token生成
在Spring Security OAuth2中,我们可以通过实现AuthorizationServerConfigurer
接口来配置token的生成方式。例如,下面是使用JWT token方式的配置:
@Configuration
@EnableAuthorizationServer
public class OAuth2AuthorizationServer extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private CustomTokenEnhancer tokenEnhancer;
@Autowired
private JwtAccessTokenConverter jwtAccessTokenConverter;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("client")
.secret("$2a$10$dfTVrVVAOPxUHBrBrQ08BOqd2v/UWLzN0doiFNqSEhDu865dPV4lS")
.authorizedGrantTypes("password","refresh_token")
.scopes("read")
.accessTokenValiditySeconds(3600)
.refreshTokenValiditySeconds(86400);
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.tokenStore(tokenStore())
.accessTokenConverter(jwtAccessTokenConverter)
.authenticationManager(authenticationManager)
.userDetailsService(userDetailsService)
.tokenEnhancer(tokenEnhancer);
}
@Bean
public TokenStore tokenStore() {
return new JwtTokenStore(jwtAccessTokenConverter);
}
@Bean
public JwtAccessTokenConverter jwtAccessTokenConverter() {
JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
converter.setSigningKey("secret");
return converter;
}
}
这样配置后,生成的token中就会包含我们自定义的字段(如custom_field
)。
3. 使用自定义Token
当我们需要使用自定义的token时,只需在调用时指定自定义的token生成方式即可。例如,在使用password
方式获取token时,可以加上如下配置:
@Configuration
public class OAuth2ResourceServer extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.antMatchers("/auth/token").permitAll()
.anyRequest().authenticated();
}
@Bean
public OAuth2RestTemplate restTemplate(OAuth2ClientContext oauth2ClientContext,
OAuth2ProtectedResourceDetails details) {
OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(details, oauth2ClientContext);
restTemplate.setAccessTokenProvider(new CustomTokenProvider());
return restTemplate;
}
private class CustomTokenProvider implements AccessTokenProvider {
private final DefaultAccessTokenProvider defaultAccessTokenProvider = new DefaultAccessTokenProvider();
@Override
public OAuth2AccessToken obtainAccessToken(OAuth2ProtectedResourceDetails details,
AccessTokenRequest request) throws UserRedirectRequiredException,
AccessTokenProviderException {
OAuth2AccessToken token = defaultAccessTokenProvider.obtainAccessToken(details, request);
OAuth2Authentication auth = new OAuth2Authentication(new DefaultOAuth2AccessToken(token), null);
DefaultOAuth2AccessToken customToken = new DefaultOAuth2AccessToken(token);
Map<String, Object> customInfo = new HashMap<>();
customInfo.put("custom_field", "custom_value");
customToken.setAdditionalInformation(customInfo);
customToken.setExpiration(token.getExpiration());
customToken.setRefreshToken(token.getRefreshToken());
customToken.setTokenType(token.getTokenType());
customToken.setScope(token.getScope());
return customToken;
}
@Override
public boolean supportsResource(OAuth2ProtectedResourceDetails resource) {
return defaultAccessTokenProvider.supportsResource(resource);
}
@Override
public boolean supportsRefresh(OAuth2ProtectedResourceDetails resource) {
return defaultAccessTokenProvider.supportsRefresh(resource);
}
}
}
在这个示例中,我们使用了CustomTokenProvider
来生成自定义的token信息。其中,我们在obtainAccessToken
方法中,通过调用默认的token生成方式获取到token信息,并在原有的token信息上添加自定义的字段信息。
至此,我们已经实现了Spring Security OAuth2中自定义token信息的攻略。
