pom dependency추가

spring boot 2.3.1버전에서 아래의 의존성을 추가해주었습니다.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

Controller @Valid 사용

    @PostMapping(value = "/api/events/", produces = MediaTypes.HAL_JSON_VALUE)
        public ResponseEntity createEvent(@RequestBody @Valid EventDto eventDto) {
            // @Valid 검증 후 결과를 Errors객체에 전달해 준다.
            if (errors.hasErrors()){
                return ResponseEntity.badRequest().build();
            }
        }

Dto 검증

@Data @Builder @NoArgsConstructor @AllArgsConstructor
public class EventDto {
    @NotEmpty
    private String name;
    @NotEmpty
    private String description;
    @NotNull
    private LocalDateTime beginEnrollmentDateTime;
    @NotNull
    private LocalDateTime closeEnrollmentDateTime;
    @NotNull
    private LocalDateTime beginEventDateTime;
    @NotNull
    private LocalDateTime endEventDateTime;
    private String location;
    @Min(0)
    private int basePrice;
    @Min(0)
    private int maxPrice;
    @Min(0)
    private int limitOfEnrollment;
}
