PortfolioController.java
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class PortfolioController {
@GetMapping("/portfolio")
public String portfolio() {
return "portfolio";
}
}
TokenController.java
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.oauth2.core.oidc.user.DefaultOidcUser;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TokenController {
@GetMapping("/token")
public String getAccessToken() {
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
DefaultOidcUser principal = (DefaultOidcUser) auth.getPrincipal();
return principal.getIdToken().getTokenValue();
}
}
推荐答案
可以尝试使用@身份验证主体，如下所示：
@RestController
public class TokenController {
@GetMapping("/token")
public String getAccessToken(@AuthenticationPrincipal OidcUser principal) {
OidcIdToken idToken = principal.getIdToken();
String idTokenValue = idToken.getTokenValue();
return idTokenValue ;
}
}
