当内容为Application/JSON时，Spring不会反序列化Object

Question

我试图在spring中创建一个端点，在那里我发送了原始JSON，它不会反序列化到对象，但如果我使用表单Data，它可以正常工作。我只是想知道我做错了什么？

这是目标

@Document("Boats")
@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
public class Boat{
@Id
private String id;
private Boolean online;
private String boatName;
private String lastOnline;
private String password;
@JsonIgnore
@Transient
private java.net.InetAddress inetAddress;
private String displayAddress;
private String displayStatus;
public Boat(String boatName, InetAddress inetAddress,Boolean online) {
this.online = online;
this.boatName = boatName;
this.inetAddress = inetAddress;
this.displayAddress = inetAddress.getHostAddress();
if(online){
String pattern = "E, dd MMM yyyy HH:mm:ss z";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);
simpleDateFormat.setTimeZone(TimeZone.getTimeZone("CST"));
this.lastOnline = simpleDateFormat.format(new Date());
}
updateDisplayStatus();
}
public void updateDisplayStatus(){
if(getOnline()){
setDisplayStatus(BoatStatus.ONLINE.getDisplayText());
}else{
setDisplayStatus(BoatStatus.OFFLINE.getDisplayText());
}
}
}

这是终点

@PostMapping(path= "/boat/update")
public ResponseEntity updateBoat(@RequestBody Boat boat){
boatFacade.updateBoat(boat);
return ResponseEntity.ok().build();
}

这是请求的正文

{
"id":"62ca4f7c5a3e0f1411445065",
"online":"false",
"boatName":"dfsjkdfsd",
"lastOnline":"null",
"password":"null",
"displayAddress":"10.50.50.50",
"displayStatus":"ONLINE"
}

这些是我正在使用的POM依赖项，不确定是否缺少依赖

始终建议指定端点使用/生成的数据的类型/种类。

@PostMapping(value = "/boat/update", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
