我正在尝试使用spring Boot 和keycloak来运行一些简单的应用程序。

这是我的应用程序.yml，其中keycloak监听本地主机上的端口8080。

server:
  port: "80"
spring:
  application.name: ${APPLICATION_NAME:spring-security-keycloak-oauth}
  security:
    oauth2:
      client:
        provider:
          keycloak:
            issuer-uri: http://localhost:8080/realms/webReport
        registration:
          keycloak:
            client-id: testK

有效的重新导向URI：地址：
对于测试，我使用控制器：

@RestController
@RequestMapping("/api")
public class SampleController {

    @GetMapping("/anonymous")
    public String getAnonymousInfo() {
        return "Anonymous";
    }

    @GetMapping("/user")
    @PreAuthorize("hasRole('USER')")
    public String getUserInfo() {
        return "user info";
    }

    @GetMapping("/admin")
    @PreAuthorize("hasRole('ADMIN')")
    public String getAdminInfo() {
        return "admin info";
    }

    @GetMapping("/service")
    @PreAuthorize("hasRole('SERVICE')")
    public String getServiceInfo() {
        return "service info";
    }

    @GetMapping("/me")
    public Object getMe() {
        final Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        return authentication.getName();
    }
}

这是我的Web安全配置

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests(authorizeRequests -> authorizeRequests
                        .antMatchers("/api/anonymous/**").permitAll()
                        .anyRequest().authenticated())
                .oauth2Login(oauth2Login -> oauth2Login
                        .userInfoEndpoint(userInfoEndpoint -> userInfoEndpoint
                                .oidcUserService(this.oidcUserService())
                        )
                );

    }

    @Bean
    public OAuth2UserService<OidcUserRequest, OidcUser> oidcUserService() {
        final OidcUserService delegate = new OidcUserService();

        return (userRequest) -> {
            OidcUser oidcUser = delegate.loadUser(userRequest);

            final Map<String, Object> claims = oidcUser.getClaims();
            final JSONArray groups = (JSONArray) claims.get("groups");

            final Set<GrantedAuthority> mappedAuthorities = groups.stream()
                    .map(role -> new SimpleGrantedAuthority(("ROLE_" + role)))
                    .collect(Collectors.toSet());

            return new DefaultOidcUser(mappedAuthorities, oidcUser.getIdToken(), oidcUser.getUserInfo());
        };
    }
}

但当我试着去举例时：“http：//localhost：80/api/admin”我收到一个错误：“无效参数：redirect_uri”控制台输出：“获取http：//本地主机：8080/领域/Web报告/协议/开放ID连接/身份验证？响应类型=代码&客户端ID=我的Web报告&状态=***重定向URI=http：//本地主机/登录/oauth2/代码/密钥伪装400（错误的请求）”
从其他线程的建议没有帮助，所以我只是不知道，该怎么办。
