Spring Boot 中 跨域配置

@Configuration
public class GlobalCorsConfig {

    @Bean
    public CorsFilter corsFilter() {

        //1. 添加 CORS配置信息
        CorsConfiguration config = new CorsConfiguration();
    
        //放行哪些原始域
        config.addAllowedOrigin("*");

        //是否发送 Cookie
        config.setAllowCredentials(true);

        //放行哪些请求方式
        config.addAllowedMethod("*");

        //放行哪些原始请求头部信息
        config.addAllowedHeader("*");
        
        //暴露哪些头部信息
        config.addExposedHeader("*");

        //2. 添加映射路径
        UrlBasedCorsConfigurationSource corsConfigurationSource = new UrlBasedCorsConfigurationSource();

        corsConfigurationSource.registerCorsConfiguration("/**", config);

        //3. 返回新的CorsFilter
        return new CorsFilter(corsConfigurationSource);
    }


}

@Configuration
public class CorsConfig implements WebMvcConfigurer {
    
    @Override
    public void addCorsMappings(CorsRegistry registry) {

        registry.addMapping("/**")

                //是否发送Cookie
                .allowCredentials(true)

                //放行哪些原始域
                .allowedOrigins("*")

                .allowedMethods("GET", "POST", "PUT", "DELETE")

                .allowedHeaders("*")

                .exposedHeaders("*");

    }
