我正在学习Spring boot，遇到了一个问题。我创建了一个Expense类，如下所示:
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Data
@Table(name="expense")
public class Expense {
@Id
private Long id;
private Instant expensedate;
private String description;
private String location;
@ManyToOne
private Category category;
@JsonIgnore
@ManyToOne
private User user;
}
现在我正试图创建一个 "控制 "来 "添加/删除 "支出对象。以下是创建Expense对象的方法:
@PostMapping("/expenses")
ResponseEntity<Expense> createExpense(@Valid @RequestBody Expense expense) throws URISyntaxException{
Expense result = expenseRepository.save(expense);
return ResponseEntity.created(new URI("/api/expense" + result.getId())).body(result);
}
但在这个方法中，我得到了以下错误:
The method getId() is undefined for the type Expanse
