controller method

아래 list api 호출하니 위와 같은 워닝이 떴다

public Page<AdminPatientSurveyProgressListItemReadDTO> getList() {}

해결

PageImpl Serialization 때문이어서 Application 에 어노테이션을 추가해줬다

@EnableSpringDataWebSupport(pageSerializationMode = PageSerializationMode.VIA_DTO)
@SpringBootApplication
public class MyApp {
}
