java Jackson无法识别存在的字段
这是我的JSON
{"totalSize":46,"done":true,"records":[{"Name":"Wamu I","Start_Date__c":"2016-09-26T16:56:10.000+0000","Status__c":"Completed","Type__c":"Your were expecting success, but In reality it was I, Dio!!!"}]}
下面是我的两个实体类:
@JsonIgnoreProperties(ignoreUnknown = true)
public class EsidesiJobEntity {
@JsonProperty("totalSize")
private @Getter @Setter Integer totalSize;
@JsonProperty("done")
private @Getter @Setter Boolean isDone;
@JsonProperty("records")
private @Getter @Setter List<KarsEntity> records;
@Override
@JsonIgnore
public String toString(){
List<String> recordsObjectString = new ArrayList<String>();
this.records.forEach((record) ->
{
recordsObjectString.add(record.toString());
});
return "{ totalSize:"+this.totalSize+", isDone:"+this.isDone+", records:["+recordsObjectString.toString()+"]";
}
}
@JsonIgnoreProperties(ignoreUnknown = true)
public class KarsEntity {
@JsonProperty("Name")
private @Getter @Setter String name;
@JsonProperty("Start_Date__c")
private @Getter @Setter String startDate;
@JsonProperty("Status__c")
private @Getter @Setter String status;
@Override
public String toString(){
return "{ name:"+this.name+", startDate:"+this.startDate+", status:"+this.status+"}";
}
}
出于某种原因,当我将该json字符串映射到EsidesJobEntity时,会出现以下错误:
Unrecognized field "totalSize"
但它肯定存在于JSON和实体中
下面是我编写的代码,用于将字符串映射到实体以供参考:
EsidesiEntity apexJobResponseEntity;
ObjectMapper apexMapper = new ObjectMapper();
try {
apexJobResponseEntity = apexMapper.readValue(apexResponseString, EsidesiEntity.class);
} ...
我是不是错过了一些基本的东西
(顺便说一句,如果类/实体名称中存在一些不一致,那是因为我在将它们发布到网上之前对它们进行了重命名。请告诉我,我会在看到它们时修复它们。)
谢谢

您正在使用Lombok。Jackson看不到你的getter和setter方法
所以你有两个选择:
如果您使用的是maven,那么将jackson lombok添加到您的pom中。xml:
然后用以下方式配置
ObjectMapper
