在我的SpringBoot应用程序中,我用以下方式定义了一个Controller:
@RestController
@RequestMapping("/api/book")
@Slf4j
public class BookController {
@PostMapping("/create")
public ResponseEntity<String> createBook(@RequestBody BookCreationPayload payload) {
log.info(payload.getName());
log.info(payload.getAuthor());
log.info(payload.getEBookReference());
return ResponseEntity.ok().body("Created successfully!");
}
}
相应的有效载荷定义如下:
@Data
public class BookCreationPayload {
private String name;
private String author;
private String eBookReference;
}
当我用下面的requestbody访问端点时,eBookReference
属性为null。
{
"name":"Kafka on the Shore",
"author": "Haruki Murakami",
"eBookReference": "https://www.pdfdrive.com/kafka-on-the-shore-e191718472.html"
}
现在,如果我将属性名更改为electronicBookReference
,它工作得很好。我认为Jackson由于一些命名约定问题而无法序列化它,但我不知道到底发生了什么。
这是我的pom.xml。

正如@xerx593在评论中提到的,问题是关于命名约定和由Lombok生成的Getter Setter方法,如果你不想使用@JsonProperty @JsonCreator,解决方案是手动创建Getter & Setter方法,如下所示。
这与上面提到的请求有效负载一起工作,因为Jackson使用类getters和setters方法进行序列化和反序列化。这些方法中的“get”,“is”和“set”后面的内容将用作JSON字段的键。
