Json 字符串如下:

{"data":[{"created":1603336724000,"updated":1603336724000,"id":"10785697","fromImageId":"0","fromCidId":"10785696","imageData":"http://44.80.20.118/download/image/2020/10/22/2020-10-22-11-18-44-074-3357.jpg","xm":"cenzhizhi","score":0.0,"type":4,"cid":null,"realName":"","gender":"","time":1603336724000,"age":"-1"}],"errCode":0,"maxPage":0,"total":1,"count":0}

对象如下

public class IntelliUserRespVo {
    private List<IntellifUserAuthVo> data;
    private Integer errCode;
    private Integer maxPage;
    private Integer total;
    private Integer count;

    public List<IntellifUserAuthVo> getData() {
        return data;
    }

    public void setData(List<IntellifUserAuthVo> data) {
        this.data = data;
    }


...


public class IntellifUserAuthVo {

    @ApiModelProperty("姓名")
    private String xm;
    @ApiModelProperty("照片地址  暂不可访问")
    private String photo;
    @ApiModelProperty("照片Base")
    private String photoBase; // base64
    @ApiModelProperty("cid")
    private String fromCidId;
    @ApiModelProperty("手机号码,可能存在多个")
    private String sjhm;
    @ApiModelProperty("联系地址")
    private String dsmc;
    @ApiModelProperty("身份证")
    private String gmsfhm;
    @ApiModelProperty("民族名称")
    private String mzmc;


    public String getXm() {
        return xm;
    }

    public void setXm(String xm) {
        this.xm = xm;
    }

...

方法如下:

 IntelliUserRespVo respVo = Json.fromJson(IntelliUserRespVo.class, httpResponse.body());
        return respVo.getData().get(0).getFromCidId();

异常如下:

请问这个怎么处理呀

什么版本

List 用了java.awt.List ?

测试了一下, 并没有报错, 只是字段对不上, 很多数据丢了

确实是List对象引用错了,不过有一个新的问题

{"data":{"created":1603336724000,"updated":1603336724000,"id":"10785696","xm":"郭景祥","photo":"http://44.80.20.118/download/image/2020/10/22/2020-10-22-11-18-44-074-3357.jpg","dsmc":"北京大院79号","gmsfhm":"350054214141425","sjhm":"151454541,","cjsj":752083200000,"mzmc":"汉族"},"errCode":0,"maxPage":0,"total":0,"count":0}

        IntelliUserRespVo respVo = Json.fromJson(IntelliUserRespVo.class, httpResponse.body());

对象里面并没有使用created updated字段

数据都不一样, 之前data是List, 现在变成了对象
