在Spring Boot中禁用“视图中打开”功能会使CORS停止工作

Question

我的Spring Boot应用程序中的CORS配置有效。我想自己管理交易，因此我决定通过将application.yaml设置为false来禁用视图中的打开：

spring:
  jpa:
    open-in-view: false

CORS配置：

@Bean
    public CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.addAllowedOrigin("http://localhost:4200");
        configuration.addExposedHeader("Authorization");
        configuration.addExposedHeader("Concurrency");
        configuration.addAllowedMethod("*");
        configuration.addAllowedHeader("*");
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

出于某种原因，我无法弄清楚，这会阻止CORS正常工作，浏览器一直在说：

Access to XMLHttpRequest at 'http://localhost:8080/api/batch' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

即使该标头实际上存在于飞行前OPTIONS请求中。 Tomcat不会记录可能解释此情况的异常或感兴趣的日志条目。
