@Entity
public class MemberSchedule {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Getter @Setter
private long id;
@ManyToOne
@JoinColumn(name = "member_id")
@Getter @Setter
private Member member;
@Getter @Setter
private String content;
@Getter @Setter
private LocalDateTime start_time;
@Getter @Setter
private LocalDateTime end_time;
@Getter @Setter
private Boolean finish;
@ManyToOne
@JoinColumn(name = "interest_id")
@JsonProperty("interest")
@Getter @Setter
private Interest interest;
}
@GetMapping
public Iterable<MemberSchedule> getMemberSchedule(@PathVariable long user_id) {
return memberScheduleRepository.findAll(Sort.by("start_time"));
}
I have MemberSchedule Entity and I want to get all items sorted by "start_time", but error occurs with message No property start found for type Member Schedule!.
I think the reason is Sort.by() didn’t recognize _ string. Because using other property like "content" works well.
@GetMapping
public Iterable<MemberSchedule> getMemberSchedule(@PathVariable long user_id) {
return memberScheduleRepository.findAll(Sort.by("content"));
}
How can I solve this problem?
error log
org.springframework.data.mapping.PropertyReferenceException: No property start found for type MemberSchedule!

Answer
Adding my comment as an answer:
You should use camelCase for naming variables in Java. If you need to then match the variable with one in snake case (let’s say it’s named start_time in a json file) you can use annotations like @JsonProperty
