spring-boot - CORS Origin Spring Boot Jhipster - 飞行前失败

Question

我正在使用 jhipster v2.27.2
我通过取消注释 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 token 时，我仍然看到这个错误

http://localhost:8080/oauth/token?username=admin&password=admin&grant_type=password&scope=read. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9090' is therefore not allowed access. The response had HTTP status code 401.

看起来像在默认 SecurityConfiguration ，它不会跳过 OPTIONS 的安全检查。

尝试添加以下内容 antMatcher到 protected void configure(HttpSecurity http) SecurityConfiguration.java 中的方法

.antMatchers(org.springframework.http.HttpMethod.OPTIONS, "/api/**").permitAll()
