Java解决Jackson反序列化字段名不匹配问题

{
    "id": null,
    "msg": null,
    "isSuccess": true,
    "code": null,
    "data": {
        "Total": 1700,
        "Rows": [...]
    }
}

@Data
public class ExamListResponseVo {
    private Object id;
    private String msg;
    private boolean isSuccess; // 问题1：Jackson 默认会去掉 is 前缀
    private Object code;
    private ExamListData data;

    @Data
    public static class ExamListData {
        private Integer total; // 问题2：JSON 中是 "Total"，大小写不匹配
        private List<ExamRow> rows;
    }
}

private boolean success; // 改为 success，与 Jackson 默认行为一致

@JsonProperty("isSuccess") // 强制匹配 JSON 中的 isSuccess
private boolean isSuccess;

ObjectMapper mapper = new ObjectMapper();
mapper.configure(MapperFeature.USE_STD_BEAN_NAMING, true); // 禁止自动去掉 is 前缀

private Integer Total; // 与 JSON 完全一致

@JsonProperty("Total")
private Integer total;

ObjectMapper mapper = new ObjectMapper();
mapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, true);

@Data
@JsonIgnoreProperties(ignoreUnknown = true) // 忽略 JSON 中多余的字段
public static class ExamListData {
    private Integer total;
    private List<ExamRow> rows;
}

@Data
@JsonIgnoreProperties(ignoreUnknown = true) // 可选：忽略未知字段
public class ExamListResponseVo {
    private Object id;
    private String msg;
    @JsonProperty("isSuccess") // 显式指定 JSON 字段名
    private boolean isSuccess;
    private Object code;
    private ExamListData data;

    @Data
    public static class ExamListData {
        @JsonProperty("Total") // 显式指定 JSON 字段名
        private Integer total;
        private List<ExamRow> rows;
    }
}

ObjectMapper mapper = new ObjectMapper();
// 可选：全局配置
// mapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, true);

String responseBody = "..."; // JSON 字符串
ExamListResponseVo result = mapper.readValue(responseBody, ExamListResponseVo.class);
