关于java：反序列化对象时忽略嵌套的json字段

Ignore a nested json field when deserializing object

我正在尝试使用JACKSON反序列化此JSON字符串，

{
"name":"United Kingdom",
"woeid": 23424975,
"placeType": {
"name":"Country",
"code": 12
}
}
]

@JsonIgnoreProperties(ignoreUnknown = true)
public class Woeid {
private String name;
private Long woeid;

public Woeid() {
}

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Long getWoeid() {
return woeid;
}
public void setWoeid(Long woeid) {
this.woeid = woeid;
}
@Override
public String toString() {
return name;
}
}

我使用此代码进行反序列化

public List<Woeid> parse(String json) throws IOException {
jp = jsonFactory.createParser(json);
Woeid[] woeids= objectMapper.readValue(jp, Woeid[].class);
return Arrays.asList(woeids);
}

但是这个错误一直存在，只有当我从json字符串中删除"placeType"时它才有用
