创建一个新的类配置来配置我的示例中的变量

@EnableWebMvc
@Configuration
public class CORSConfig {

    @Bean
    public WebMvcConfigurer CORSConfigurer(){
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/vehicles/**")
                .allowedOrigins("*")
                .allowedHeaders("header1", "header2", "header3")
                .exposedHeaders("header1", "header2")
                .allowedMethods("GET", "POST", "PUT","DELETE");
            }
        };
    }
}
