Question

我正在创建一个spring Boot应用程序，我在其中使用Restful Api并通过POSTMAN以JSON格式发送数据。我希望数据与我的模型类一起映射，即请求数据类，但我得到空值。

主要班级

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ContactApplication {

    public static void main(String[] args) {
        SpringApplication.run(ContactGEApplication.class, args);
    }
}

控制器类 - 这个是控制器类。在这个类中，我们将使用/ rfs映射url import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.http.MediaType; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

@RestController
public class ContactController {

    private static Log log = LogFactory.getLog(ContactController.class);

    @RequestMapping(value = "/rfs", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
    public ServiceResponse<String> serviceRequest(@RequestBody RequestData requestData) throws JsonProcessingException {

        System.out.println(requestData);
        System.out.println("M in controller");
        return ServiceResponse.success();

    }
}

请求Data.java-这是我的模型类。在此我定义了所有字段和getter以及setter

public class RequestData {

    private static final long serialVersionUID = 1L;
    private String EquipmentID;
    private String Modality;
    private String FacilityID;
    private String CountryCode;
    private String ISOCode;
    private String ProblemType;
    private String ProblemArea;
    private String EquipmentStatus;
    private String Name;
    private String PhoneNumber;
    private String Extension;
    private String Description;
    private String ShortDescription;
    private String TimePeriod;
    private String ServiceCode;
    private String Locale;
    private String RequestingApp;
    private String ExamNumber;
    private String SeriesNumber;
    private String ImageNumber;

    public String getEquipmentID() {
        return EquipmentID;
    }

    public void setEquipmentID(String equipmentID) {
        EquipmentID = equipmentID;
    }

    public String getModality() {
        return Modality;
    }

    public void setModality(String modality) {
        Modality = modality;
    }

    public String getFacilityID() {
        return FacilityID;
    }

    public void setFacilityID(String facilityID) {
        FacilityID = facilityID;
    }

    public String getCountryCode() {
        return CountryCode;
    }

    public void setCountryCode(String countryCode) {
        CountryCode = countryCode;
    }

    public String getISOCode() {
        return ISOCode;
    }

    public void setISOCode(String iSOCode) {
        ISOCode = iSOCode;
    }

    public String getProblemType() {
        return ProblemType;
    }

    public void setProblemType(String problemType) {
        ProblemType = problemType;
    }

    public String getProblemArea() {
        return ProblemArea;
    }

    public void setProblemArea(String problemArea) {
        ProblemArea = problemArea;
    }

    public String getEquipmentStatus() {
        return EquipmentStatus;
    }

    public void setEquipmentStatus(String equipmentStatus) {
        EquipmentStatus = equipmentStatus;
    }

    public String getName() {
        return Name;
    }

    public void setName(String name) {
        Name = name;
    }

    public String getPhoneNumber() {
        return PhoneNumber;
    }

    public void setPhoneNumber(String phoneNumber) {
        PhoneNumber = phoneNumber;
    }

    public String getExtension() {
        return Extension;
    }

    public void setExtension(String extension) {
        Extension = extension;
    }

    public String getDescription() {
        return Description;
    }

    public void setDescription(String description) {
        Description = description;
    }

    public String getShortDescription() {
        return ShortDescription;
    }

    public void setShortDescription(String shortDescription) {
        ShortDescription = shortDescription;
    }

    public String getTimePeriod() {
        return TimePeriod;
    }

    public void setTimePeriod(String timePeriod) {
        TimePeriod = timePeriod;
    }

    public String getServiceCode() {
        return ServiceCode;
    }

    public void setServiceCode(String serviceCode) {
        ServiceCode = serviceCode;
    }

    public String getLocale() {
        return Locale;
    }

    public void setLocale(String locale) {
        Locale = locale;
    }

    public String getRequestingApp() {
        return RequestingApp;
    }

    public void setRequestingApp(String requestingApp) {
        RequestingApp = requestingApp;
    }

    public String getExamNumber() {
        return ExamNumber;
    }

    public void setExamNumber(String examNumber) {
        ExamNumber = examNumber;
    }

    public String getSeriesNumber() {
        return SeriesNumber;
    }

    public void setSeriesNumber(String seriesNumber) {
        SeriesNumber = seriesNumber;
    }

    public String getImageNumber() {
        return ImageNumber;
    }

    public void setImageNumber(String imageNumber) {
        ImageNumber = imageNumber;
    }

    public static long getSerialversionuid() {
        return serialVersionUID;
    }

    @Override
    public String toString() {
        return "RequestData [EquipmentID=" + EquipmentID + ", Modality=" + Modality + ", FacilityID=" + FacilityID
                + ", CountryCode=" + CountryCode + ", ISOCode=" + ISOCode + ", ProblemType=" + ProblemType
                + ", ProblemArea=" + ProblemArea + ", EquipmentStatus=" + EquipmentStatus + ", Name=" + Name
                + ", PhoneNumber=" + PhoneNumber + ", Extension=" + Extension + ", Description=" + Description
                + ", ShortDescription=" + ShortDescription + ", TimePeriod=" + TimePeriod + ", ServiceCode="
                + ServiceCode + ", Locale=" + Locale + ", RequestingApp=" + RequestingApp + ", ExamNumber=" + ExamNumber
                + ", SeriesNumber=" + SeriesNumber + ", ImageNumber=" + ImageNumber + "]";
    }

}

Answer 1

问题似乎是RequestData中的字段全部大写。这似乎导致getter和反序列化器出现问题。如果您将字段更改为以小写字母开头，并且在JSON请求中使用匹配的小写字段，则会填充RequestData。

Answer 2

在Rest中的方法之前添加@ResponseBody

@RestController
public class ContactGEController {

    private static Log log = LogFactory.getLog(ContactGEController.class);

    @RequestMapping(value = "/rfs", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
    public ServiceResponse<String> serviceRequest(@RequestBody RequestData requestData) throws JsonProcessingException {

        System.out.println(requestData);
        System.out.println("M in controller");
        return ServiceResponse.success();

    }
}

无法将数据从JSON绑定到模型类
