无法在Spring Security中为oauth/token端点启用CORS

我无法在SpringRESTAPI上为oauth/token端点启用CORS支持

资源服务器配置：

@配置
@EnableResourceServer
受保护的静态类ResourceServerConfiguration扩展了ResourceServerConfigurerAdapter{
@自动连线
私有CustomAuthenticationEntryPoint CustomAuthenticationEntryPoint；
@自动连线
私有CustomLogoutSuccessHandler CustomLogoutSuccessHandler；
@自动连线
私人授权服务角色服务；
@豆子
公共访问决策管理器访问决策管理器（）{
List我通过从configure（HttpSecurity http）Override方法中删除.addFilterBefore（corsFilter（），ChannelProcessingFilter.class）修复了它。
希望它有意义为什么？
