使用内部类转换为嵌套的pojo类

Question

我的杰森：

this.restify.use((req, res, next) => {
                      res.header("API-TOKEN", 'GHYTYEUJSJSHHEYHJSH');
                     return next();

Answer 1

您收到此错误是因为您在类的顶部放置了 @JsonFormat（shape = JsonFormat.Shape.ARRAY）批注，对于您而言，我认为这是不必要的。

您的POJO类中也存在一些错误，它缺少accountCode字段，并且createdDate字段被命名为creationDate。

public class ECCSGetExtraCustomer {

    private String accountId;
    private String accountCode;
    private String createdDate;
    //... + Getters and setters
}

要反序列化您的json为列表，您可以这样：

public class LaunchDebug {

    public void main() throws Exception {

        ObjectMapper objectMapper = new ObjectMapper();
        List<ECCSGetExtraCustomer> eccsGetExtraCustomer = Arrays.asList(objectMapper.readValue(value, ECCSGetExtraCustomer[].class));
        System.out.println(eccsGetExtraCustomer.toString());

    }

}
