web.xml을 Java 구성으로 이식 한 후 다음 문제가 발생합니다.
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:63342' is therefore not allowed access.
몇 가지 Spring 참조를 기반으로 다음 시도가 시도되었습니다.
@Configuration
@ComponentScan(basePackageClasses = AppConfig.class, useDefaultFilters = false, includeFilters = {
@Filter(org.springframework.stereotype.Controller.class) })
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/*").allowedOrigins("*").allowedMethods("GET", "POST", "OPTIONS", "PUT")
.allowedHeaders("Content-Type", "X-Requested-With", "accept", "Origin", "Access-Control-Request-Method",
"Access-Control-Request-Headers")
.exposedHeaders("Access-Control-Allow-Origin", "Access-Control-Allow-Credentials")
.allowCredentials(true).maxAge(3600);
}
}
선택한 값은 작동중인 web.xml 필터에서 가져 왔습니다.

Spring Java 구성 접근 방식이 web.xml 파일처럼 작동하지 않는 이유는 무엇입니까?
