我正在使用java应用程序中的两个应用程序我想使用httppost将报告发送到spring应用程序，我创建了端点，在尝试发送报告之后，我得到了关于成功身份验证的响应，另外我得到了异常：

JSON parse error: Cannot deserialize instance of `java.lang.String` out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.lang.String` out of START_OBJECT token
 at [Source: (PushbackInputStream); line: 1, column: 153] (through reference chain: pl.mr.form.ReportDataForm["reportData"])]

我的报告看起来如何：

public class FileResult {
    private String filePath;
    private String diskName;
    private String status;

另一个类具有fileresult对象列表：

public class FileSystemResult extends ReportData {
    private List<FileResult> fileResults;
}

reportdata类是空类，只是为了添加posibility extend others类而创建的，我的报表类看起来：

public class Report implements Serializable {
    private Type type;  // enum
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = DATE_TYPE)
    private ZonedDateTime scanDate;
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = DATE_TYPE)
    private ZonedDateTime reportDate;
    private ReportData reportData;
    private String serailId;

这是我发报告的班级：

public void sendReport(final Report report) {
        if (report == null) {
            log.error("Can't send null");
        }
        try (CloseableHttpClient client = HttpClients.createDefault()) {
            String token = getTokenFromProperties();
            if (token != null) {
                log.info("Token is equals = " + token);
            } else {
                log.error("Token not found");
            }
            HttpPost httpPost = new HttpPost("http://localhost:8080/marcin/sendReport");
            String json = convertReportToJson(report);
            log.info(json);
            StringEntity entity = new StringEntity(json);
            httpPost.setEntity(entity);
            httpPost.setHeader("Accept", "application/json");
            httpPost.setHeader("Authorization", "Bearer " + token);
            httpPost.setHeader("Content-type", "application/json;charset=UTF-8");
            CloseableHttpResponse response = client.execute(httpPost);
            log.info(response.toString());
        } catch (IOException e) {
            e.printStackTrace();
            log.error("" + e.getMessage());
        }
    }
    private String convertReportToJson(Report report) {
        ObjectMapper mapper = new ObjectMapper();
        try {
            mapper.registerModule(new JavaTimeModule());
            return mapper.writeValueAsString(report);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
            return null;
        }
    }

我要发这个报告的主要课程是：

public static void main(String[] args) {
        FileSystemResult fileSystemResult = new FileSystemScanResult();
        fileSystemResult.setFileResults(List.of(new FileResult("ABC", "mroma", "OK"),
                new FileScanResult("POL", "mroma", "ERROR")));
        Report newReport = new Report(Report.Type.FILE_SCAN, ZonedDateTime.now(ZoneId.of("UTC")), ZonedDateTime.now(ZoneId.systemDefault()),  fileSystemResult);
        ReportService rs = new ReportService();
        rs.sendReport(newReport);
    }

另外，当我从report类中删除reportdata时，一切正常
