spring-boot - 使用KeycloakWebSecurityConfigurerAdapter时控制器中的spring boot null MultipartFile

Question

我正在使用带有用于 Oauth2 的 keycloak 适配器的 Spring Boot 2.6.3，在带有文件上传或多部分文件上传的端点上，所有部分都是空的，并且控制器在没有使用 KeycloakWebSecurityConfigurerAdapter 的项目上接收 null 作为 MultipartFile 文件值，它可以解决盒子。

有趣的是，如果我手动调用 ((HttpServletRequest) request).getParts(); 在调用控制器之前的最后一个过滤器中，部件设置正常。

对此有任何线索吗？

我的安全配置

  @KeycloakConfiguration
@EnableGlobalMethodSecurity(prePostEnabled = true)

    private final String swaggerUrl;

        this.swaggerUrl = swaggerUrl;
        this.corsFilter = corsFilter;
        this.customSecurityConfig = customSecurityConfig;
    }

        FilterRegistrationBean registrationBean = new FilterRegistrationBean(filter);
        registrationBean.setEnabled(false);

        customSecurityConfig.configureEndpointSecurity(http);
