[스프링 기반 REST API 개발] Event 생성 API, 테스트 코드

ModelMapper 의존성 추가

<dependency>
            <groupId>org.modelmapper</groupId>
            <artifactId>modelmapper</artifactId>
            <version>2.3.9</version>
</dependency>

EventDto 추가

package me.jumen.demoinflearnrestapi.events;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.time.LocalDateTime;

@Builder
@NoArgsConstructor
@AllArgsConstructor
@Data
public class EventDto {
    private Integer id;
    private String name;
    private String description;
    private LocalDateTime beginEnrollmentDateTime;
    private LocalDateTime closeEnrollmentDateTime;
    private LocalDateTime beginEventDateTime;
    private LocalDateTime endEventDateTime;
    private String location; // (optional) 이게 없으면 온라인 모임
    private int basePrice; // (optional)
    private int maxPrice; // (optional)
    private int limitOfEnrollment;

}

 

EventController

    @PostMapping
    public ResponseEntity createEvent(@RequestBody EventDto eventDto) {
        Event event = modelMapper.map(eventDto, Event.class);

        Event newEvent = this.eventRepository.save(event);

        URI createdUri = linkTo(EventController.class).slash(newEvent.getId()).toUri();
        return ResponseEntity.created(createdUri).body(newEvent);
    }

modelMapper를 통해 EventDto -> Event 변환

Dto와 modelMapper를 통해 입력값을 제한할 수 있다. 

 

HATEOAS가 제공하는 linkTo(), methodOn() 사용해서 Location URI 만들기

linkTo()로 생성된 uri : http://localhost:8080/api/events/1

ResponseEntity에 넣어주면, Http Header에 Location  = http://localhost:8080/api/events/1로 들어간다.

@Test
    public void create() throws Exception {
        EventDto eventDto = EventDto.builder()
                .name("안녕 이벤트")
                .description("배고프다")
                .beginEnrollmentDateTime(LocalDateTime.of(2018, 11, 2, 8, 0))
                .closeEnrollmentDateTime(LocalDateTime.of(2018, 11, 3, 8, 0))
                .beginEventDateTime(LocalDateTime.of(2018, 11, 4, 8, 0))
                .endEventDateTime(LocalDateTime.of(2018, 11, 5, 8, 0))
                .basePrice(0)
                .maxPrice(0)
                .location("네이버 D2 팩토리 좁았음")
                .limitOfEnrollment(100)
                .build();

        this.mockMvc.perform(post("/api/events")
                    .contentType(MediaType.APPLICATION_JSON_UTF8)
                    .content(this.objectMapper.writeValueAsString(eventDto)))
                    .andDo(print())
                    .andExpect(status().isCreated())
                    .andExpect(header().exists("Location"))
                    .andExpect(jsonPath("free").value(false))
                    .andExpect(jsonPath("id").exists())
                    .andExpect(jsonPath("eventStatus").value(EventStatus.DRAFT.name()));
    }
