Spring Boot中禁止选项请求

Question

我阅读了很多关于这个问题的线程和解决方案（包括这个SO解决方案），但在发送预飞行请求时仍然有403错误。

我使用的是Spring Data Rest，只要没有发送选项，我就可以很好地处理我的存储库。我还没有使用Spring Security，但我计划很快配置它。以下是我当前的配置：

@Configuration
public class GlobalRepositoryRestConfigurer extends RepositoryRestConfigurerAdapter {

    @Override
    public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
        config.getCorsRegistry().addMapping("/**").allowedOrigins("*").allowedHeaders(
                "*").exposedHeaders("Location").allowedMethods("GET", "PUT", "POST", "DELETE",
                                                               "OPTIONS");
    }

    @Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
    public DispatcherServlet dispatcherServlet() {
        DispatcherServlet dispatcher = new DispatcherServlet();
        dispatcher.setDispatchOptionsRequest(true);
        return dispatcher;
    }
}

Accept           text/html,application/xhtml+xm…plication/xml;q=0.9,*/*;q=0.8
Accept-Encoding  gzip, deflate
Accept-Language  fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3
Access-Control-Request-Headers   content-type
Access-Control-Request-Method    POST

Host             localhost:8080

User-Agent       Mozilla/5.0 (Windows NT 10.0; …) Gecko/20100101 Firefox/64.0

Allow            GET, HEAD, POST, PUT, DELETE, OPTIONS, PATCH

我仍然不知道为什么我的配置不能用于OPTIONS请求，但我设法使它与WebMVCConfigurer一起工作。下面的配置类解决了我的问题：

@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
                .allowedOrigins("*")
                .allowedHeaders("*")
                .exposedHeaders("Location", "Access-Control-Allow-Origin");
    }
}
