[Spring]WebMvcConfigure인터페이스

Spring MVC에 대한 Java 기반 구성을 사용자 정의하기위한 콜백 메소드를 정의합니다

@Configuration
@ComponentScan
@EnableWebMvc
public class WebConfig {
    
    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver();
        internalResourceViewResolver.setPrefix("/WEB-INF/");
        internalResourceViewResolver.setSuffix(".jsp");

        return internalResourceViewResolver;
    }
}

여기서 WebMvcComfigurer를 implements 한다면 위 처럼 ViewResolver를 일일이 Bean으로 등록할 필요없이 손쉽게 EnableWebMvc 등록한 ViewResolver를 커스터마이징하면서 사용할 수 있습니다.

@Configuration
@ComponentScan
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.jsp("/WEB-INF/",".jsp");
    }
}
