이 글의 내용은 SpringBoot에 커스텀 인터셉터를 추가하는 메소드 구현(코드)에 대한 내용입니다. 필요한 친구들이 참고하시면 좋을 것 같습니다.
Controller 계층에서 작업할 때 특정 작업을 확인하거나 확인해야 하는 경우가 많으며, 각 Controller에서 반복되는 코드를 작성하려면 상대적으로 큰 작업 부하가 필요합니다. 여기 Springboot 프로젝트에서는 WebMvcConfigurerAdapter를 상속하여 인터셉터를 추가합니다.
1. WebMvcConfigurerAdapter 소스 코드

이 클래스는 예외 처리, 도메인 간 요청 및 기타 구성과 같은 다른 많은 작업도 구성할 수 있음을 볼 수 있습니다.
2. 자동 웹 구성 클래스
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; @Configuration public class WebMvcConfig extends WebMvcConfigurerAdapter { @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(getMyInterceptor()).addPathPatterns("/**"); } @Bean public MyInterceptor getMyInterceptor(){ return new MyInterceptor(); } }
여러 인터셉터를 추가해야 하는 경우 InterceptorRegistry Registry.addInterceptor 메소드
public InterceptorRegistration addInterceptor(HandlerInterceptor interceptor) { InterceptorRegistration registration = new InterceptorRegistration(interceptor); this.registrations.add(registration); return registration; }
registrations는 배열 구조이므로 여러
