Could you help me to solve a problem with passing two objects through @RequestBody?
As far as I know you can’t pass 2 @RequestBody parameters, so I’ve created Tuple class to store custom data.
In my case I need to pass a Book object and int value in json representation. I’ve already tried different ways but each time it cannot be parsed aright.
@NoArgsConstructor
@AllArgsConstructor
@Getter
@EqualsAndHashCode
@ToString
public final class Tuple<K, V> {
private K key;
private V value;
}
I use Tuple in this method.
@PutMapping("action/returnBook")
public ResponseEntity<Void> returnBook(@RequestBody final Tuple<Long, Long> userIdBookInstanceId) {
leasingHistoryService.returnBook(userIdBookInstanceId.getKey(), userIdBookInstanceId.getValue());
return new ResponseEntity<>(HttpStatus.OK);
}
@Entity
@NoArgsConstructor
@AllArgsConstructor
@Getter
@EqualsAndHashCode
@ToString
public final class Book {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String title;
@ManyToOne(cascade = CascadeType.ALL, optional = false)
private Author author;
}
@Entity
@NoArgsConstructor
@AllArgsConstructor
@Getter
@EqualsAndHashCode
@ToString
public final class Author {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
private String name;
private LocalDate dateOfBirth;
private String bio;
}
What is the structure of the json that I should pass in the PUT request?
Answer
I’ve found a way to do it. In this case it’s the following json:
{
"key" : {
"title": "The Girl in the Spider's Web v17",
"author": {
"id": 2,
"name": "Larsson",
"dateOfBirth": "1954-08-15",
"bio": "Author of the Millennium trilogy"
}
},
"value": 3
}
