具有嵌套JSON和名称为变量的Jackson模型的映射不正确

Question

我在尝试使用RoboSpice与Jackson映射做出错误的映射时发现以下错误JSON返回的错误

POST request for "https://****/api/register?email=jam@yum.com&first_name=Vege&last_name=Mite&password=qwerty12345&invite_token=oXlTvAvbVR5fiQP6DKCEVQ" 
resulted in 422 (Unprocessable Entity); invoking error handler
E//RequestRunner.java:134﹕ 19:01:34.881 Thread-15097 An exception occurred during request network execution :422 Unprocessable Entity

使用Curl我得到以下正确答案：

{"object":"Error","errors":{"email":["has already been taken"]}}

我的模型对象失败的休息如下，问题是“错误”项目没有正确映射但我不确定它应该是什么，因为变量名称“email”可以改变（即“代理” ，“供应商”等。）

@JsonIgnoreProperties(ignoreUnknown = true)
public class BaseModel {
private String id;
private String email;
private String first_name;
private String last_name;
private String street1;
private String street2;
private String city;
private String state;
private String zipcode;
private String country;
private String phone;
private String create_at;
private String object;
private Map<String, ArrayList<String>> errors;
