[문제] properties에 아래와같이 설정하면 #spring.resources.cache.cachecontrol.max-age=3600 #spring.resources.chain.enabled=true favicon.ico , data? 만 캐싱되고 js파일들은 캐싱되지 않는 문제 발생.

[해결] WebMvcConfigurer에서 설정.

@Configuration
@EnableWebMvc
public class WebConfig implements WebMvcConfigurer {
	@Override
	public void addResourceHandlers(ResourceHandlerRegistry registry) {
		registry.
			.setCachePeriod(3600)
			.resourceChain(true);
	}
}
