调用Rest WebService POST方法时出现HTTP 400错误请求

Question

请找到相关的类和JSON请求，我无法理解我的请求有什么问题，我得到400 BAD请求。请求可能甚至没有到达服务器。我没有找到丢失的线索。感谢您对此的帮助

Json请求有效负载

似乎问题在于有效负载json到控制器中的POJO广告系列的映射。我使用String转换了所有Date和LocalDate，然后尝试映射到POJO，如下所示。

我稍微修改了您的广告系列 POJO：

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

import org.springframework.format.annotation.DateTimeFormat;

@Entity
@Table(name = "Campaigns")
public class Campaigns {
    @Id
    @Column(name = "CampaignID", nullable = false)
    private Integer campaignID;

    @Column(name = "CampaignDesc", nullable = false)
    private String campaignDescription;

    @Column(name = "CampaignOption", nullable = false)
    private String campaignOption;

    @Column(name = "CountryID", nullable = false)
    private String countryID;

    @DateTimeFormat(pattern = "dd/MM/yyyy")
    @Column(name = "StartDateTime", nullable = false)
    private String startDateTime;

    @DateTimeFormat(pattern = "dd/MM/yyyy")
    @Column(name = "EndDateTime", nullable = false)
    private String endDateTime;

    @Column(name = "ChannelID", nullable = false)
    private Integer channelID;

    @Column(name = "LastUpdateBy", nullable = false)
    private String lastUpdateBy;

    @DateTimeFormat(pattern = "dd/MM/yyyy")
    @Column(name = "LastUpdateTime", nullable = false)
    private String lastUpdateTime;

    private String timestamp;

    @Column(name = "CampaignIdCRM", nullable = true)
    private String campaignIdCRM;

    @Column(name = "ClassificationCPC", nullable = true)
    private String classificationCPC;

    @Column(name = "FormCode", nullable = true)
    private String formCode;

    public Campaigns() {

    public String getLastUpdateTime() {

    }

    public void setLastUpdateTime(String lastUpdateTime) {
        this.lastUpdateTime = lastUpdateTime;

    public String getCampaignIDCRM() {
        return campaignIdCRM;
    }

    public void setCampaignIDCRM(String campaignIDCRM) {

    }

    @Override
    public String toString() {
        return "CampaignId: " + this.campaignID;
    }
}

<强> Driver.java

public static void main(String[] args) throws JsonParseException, JsonMappingException, IOException {
            String str = "{\"campaignID\":1,\"campaignDescription\":\"A Campaign #1\",\"campaignOption\":\"C\",\"countryID\":\"CI\",\"startDateTime\":\"02/04/2010\",\"endDateTime\":\"02/04/2017\",\"channelID\":3,\"lastUpdateBy\":\"bbblsdcdo\",\"lastUpdateTime\":\"02/04/2017\",\"timestamp\":\"2016-11-10 23:26:10.285\",\"campaignIdCRM\":null,\"classificationCPC\":null,\"formCode\":null}";
            ObjectMapper mapper = new ObjectMapper();
            mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
            Campaigns obj = mapper.readValue(str, Campaigns.class);
            System.out.println(obj);
    }

我希望这可以帮助您解决此问题。
