我想使用两种类型的用户:普通用户和管理员。现在,我已经拥有一个基础结构,其中管理员和用户是两种完全不同的类型:用户拥有许多仅与它们相关的内容(控制器,表,服务等),与管理员相同。因此,它们是数据库中的不同实体和不同表,并且我不想合并它们,因为它们是不同的。但是现在只有用户可以使用Spring Security OAuth2登录,而管理员不能使用主体,因此他们无法登录。请注意,我使用自己的授权和资源服务器。
因此,我想允许Spring Security对用户和管理员进行身份验证。我还想为用户和管理员使用两个不同的登录端点以及两个不同的实体和表。
这怎么办?我应该怎么做?
UPD:
我认为我应该为用户和管理员创建2个OAuth客户端,分别在grant_types
和2个oauth_client_details
中使用2个不同的AbstractTokenGranters
。
我已经有一个自定义AbstractTokenGranter
用户,可以像这样对用户进行身份验证:
//getOAuth2Authentication()
User user = userService.getUserByPhone(username);
if(user == null)
throw new BadCredentialsException("Bad credentials");
Authentication authentication = authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(Long.toString(user.getId()), password)
);
//I use Long.toString(user.getId()) because some users use FB instead of the phone,
//so I have one more `AbstractTokenGranter` for social networks,
//I don't mention about it in this post, so don't be confused
据我了解,AuthenticationManager
呼叫UserDetailsService
,现在看起来像这样:
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
UserDetails user = userRepository.findById(Long.parseLong(username)).orElseThrow(
() -> new UsernameNotFoundException("User not found with id : " + id)
);
return user;
}
但是,如果我为管理员再创建一个AbstractTokenGranter
,则当前的UserDetailsService
将不知道收到了谁的ID-管理员ID或用户ID。
作为一种解决方案,我认为我需要为管理员再创建一个UserDetailsService
。但是如何使用多个UserDetailsService
?另外,也许我应该使用完全不同的方案?

您可以定义定制的clientDetailService并覆盖loadUserByUserName方法。 是否可以查询不同的表和授权取决于您,还可以更改结构。这就是我无需多说就可以说的
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
ClientDetails clientDetails;
try {
clientDetails = clientDetailsService.loadClientByClientId(username);
} catch (NoSuchClientException e) {
throw new UsernameNotFoundException(e.getMessage(), e);
}
String clientSecret = clientDetails.getClientSecret();
if (clientSecret== null || clientSecret.trim().length()==0) {
clientSecret = emptyPassword;
}
return new User(username, clientSecret, clientDetails.getAuthorities());
}
可以修改此部分以更改结构:> authentication-manager-ref =“ clientAuthenticationManager”

1。在oauth_client_details
中的custom_grant
中,在authorized_grant_types
表中创建新的OAuth2客户端。
2。创建:
public class CustomTokenGranter extends AbstractTokenGranter {
//...
protected OAuth2Authentication getOAuth2Authentication(ClientDetails client, TokenRequest tokenRequest) {
Map<String, String> params = tokenRequest.getRequestParameters();
String username = params.getOrDefault("username", null);
String password = params.getOrDefault("password", null);
if(username == null || password == null)
throw new BadCredentialsException("Bad credentials");
CustomAuthenticationToken token = new CustomAuthenticationToken(username, password);
Authentication authentication = authenticationManager.authenticate(token);
}
}
3。在AuthorizationServerConfigurerAdapter
中添加此授予者:
private TokenGranter tokenGranter(final AuthorizationServerEndpointsConfigurer endpoints) {
List<TokenGranter> granters = new ArrayList<TokenGranter>(Arrays.asList(endpoints.getTokenGranter()));
granters.add(new CustomGrantTokenGranter(endpoints.getTokenServices(), endpoints.getClientDetailsService(), endpoints.getOAuth2RequestFactory(), "custom_grant"));
return new CompositeTokenGranter(granters);
}
现在CustomGrantTokenGranter
将收到所有custom_grant
授权类型的授权请求。
4。创建CustomAuthenticationToken extends UsernamePasswordAuthenticationToken
5。创建:
@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
@Autowired
private PasswordEncoder adminPasswordEncoder;
@Autowired
private UserDetailsService adminDetailsService;
@Override
public Authentication authenticate(Authentication auth) throws AuthenticationException {
String username = auth.getName();
String password = auth.getCredentials().toString();
UserDetails adminDetails = adminDetailsService.loadUserByUsername(username);
//adminDetailsService.loadUserByUsername(username) returns Admin inside UserDetails
if (adminPasswordEncoder.matches(password, adminDetails.getPassword()))
return new UsernamePasswordAuthenticationToken(adminDetails, password, adminDetails.getAuthorities());
else
throw new BadCredentialsException("Bad credentials");
}
@Override
public boolean supports(Class<?> auth) {
return auth.equals(CustomAuthenticationToken.class);
}
}
在这里您可以使用与其他提供商不同的UserDetailsService
6。在CustomAuthenticationProvider
中添加WebSecurityConfigurerAdapter
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomAuthenticationProvider customAuthenticationProvider;
@Override
public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) {
authenticationManagerBuilder.authenticationProvider(customAuthenticationProvider);
}
//...
}
摘要::使用此方案,您可以根据需要使用任意数量的用户类型。如果为Admin implements UserDetails
,则可以轻松地将其作为Principal
在服务器上使用。
