我正在使用jhipster v2.27.2，已通过取消注释application.yml中的行来启用cors

jhipster:
async:
    corePoolSize: 2
    maxPoolSize: 50
    queueCapacity: 10000

cors: #By default CORS are not enabled. Uncomment to enable.
    allowed-origins: "*"
    allowed-methods: GET, PUT, POST, DELETE, OPTIONS
    allowed-headers: "*"
    exposed-headers:
    allow-credentials: true
    max-age: 1800

在“ WebConfigurer”中

@Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = props.getCors();
        if (config.getAllowedOrigins() != null && !config.getAllowedOrigins().isEmpty()) {
            source.registerCorsConfiguration("/api/**", config);
            source.registerCorsConfiguration("/v2/api-docs", config);
            source.registerCorsConfiguration("/oauth/**", config);
        }
        return new CorsFilter(source);
    }

但是当我请求访问令牌时，仍然看到此错误

http：// localhost：8080 / oauth / token？username = admin＆password =
admin＆grant_type = password＆scope =
read。对预检请求的响应未通过访问控制检查：请求的资源上不存在“
Access-Control-Allow-Origin”标头。因此，不允许访问源’ http：//
localhost：9090 ‘。响应的HTTP状态码为401。
