使用@AuthenticationPrincipal注入自定义OidcUser包装器

public class CustomOidcUser implements OidcUser {
    private OidcUser oidcUser;

    public CustomOidcUser(OidcUser oidcUser) {
        this.oidcUser = oidcUser;
    }

    // 添加自定义属性和方法

    @Override
    public Map<String, Object> getClaims() {
        return oidcUser.getClaims();
    }

    // 其他方法的实现...
}

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    // 其他配置...

    @Bean
    public OidcUserArgumentResolver oidcUserArgumentResolver() {
        return new OidcUserArgumentResolver();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            // 其他配置...
            .oauth2Login()
                .userInfoEndpoint()
                    .oidcUserService(oidcUserService());
    }

    @Bean
    public OidcUserService oidcUserService() {
        return new OidcUserService() {
            @Override
            public OidcUser loadUser(OidcUserRequest userRequest) throws OAuth2AuthenticationException {
                OidcUser oidcUser = super.loadUser(userRequest);
                return new CustomOidcUser(oidcUser);
            }
        };
    }
}

@GetMapping("/user")
public String getUserInfo(@AuthenticationPrincipal CustomOidcUser oidcUser) {
    // 使用自定义的OidcUser包装器对象进行处理
    // 可以访问自定义属性和方法
    return oidcUser.getName();
}
