[英]Spring OAuth2 Custom Authentication Manager ClassCastException
i've a big problem and no idea how to solve it... I need to use customAuthenticationManager for third party log-in in my spring boot application, but when i declare custom authenticator i get : 我有一个大问题,不知道如何解决...我需要在春季启动应用程序中使用customAuthenticationManager进行第三方登录,但是当我声明自定义身份验证器时,我会得到:
Handling error: 处理错误:
ClassCastException, java.lang.String cannot be cast to com.nexus.demooauth.models.User
If i use default authentication manager (the one that comes with spring boot) everything works fine. 如果我使用默认的身份验证管理器(Spring Boot附带的那个),则一切正常。
Here is Websecurity.java 这是Websecurity.java
@Configuration
public class WebSecurity extends WebSecurityConfigurerAdapter {
@Bean
public AuthenticationManager customAuthenticationManager() throws Exception {
return new CustomAuthenticationManager();
}
AuthorizationServerConfig.java AuthorizationServerConfig.java
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
UserDetailsService customUserDetailsService;
@Autowired
DataSource dataSource;
@Autowired
private AuthenticationManager authenticationManager;
@Bean
public PasswordEncoder passwordEncoder() {
return new Plainencoder();
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer configurer) throws Exception {
//configurer.userDetailsService(customUserDetailsService);
configurer.authenticationManager(authenticationManager);
configurer.tokenEnhancer(tokenEnhancer());
}
@Bean
public TokenEnhancer tokenEnhancer() {
return new CustomTokenEnhancer();
}
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory().withClient("gigy").secret("secret").accessTokenValiditySeconds(8400)
.scopes("read", "write").authorizedGrantTypes("password", "refresh_token");
}
CustomAuthenticationManager.java CustomAuthenticationManager.java
@Service
public class CustomAuthenticationManager implements AuthenticationManager{
private final Logger logger = LoggerFactory.getLogger(CustomAuthenticationManager.class);
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
String username = authentication.getName();
String pw = authentication.getCredentials().toString();
logger.info("was here" + username.toString() + " , " + pw.toString());
return new UsernamePasswordAuthenticationToken(username, pw, authentication.getAuthorities());
}
It actually prints in logger 它实际上在记录器中打印
2018-05-15 17:58:34.453 INFO 7212 --- [nio-8089-exec-1] c.n.d.s.CustomAuthenticationManager : was heretest , test
When debugging it breaks when returning new UsernamePasswordAuthenticationToken in some obfuscated class. 调试时,在某些混淆的类中返回新的UsernamePasswordAuthenticationToken时,它会中断。
Actually found the anserw. 居然找到了anserw。 The problem was in CustomTokenEnhancer that was making this invalid conversion. 问题出在进行这种无效转换的CustomTokenEnhancer中。
