如何将带有反斜杠的json从mysql db转换为普通json

Question

我必须将带有反冲格式的JSON从MySQL数据转换为普通的Json。

我尝试执行以下代码时出现

错误

"{"billing_street_address":"","billing_street_address_2":"","billing_city_town":"","billing_state_province":"","billing_country":"","billing_postal_code":"","shipping_street_address":"7047 N Ashland Blvd","shipping_street_address_2":"","shipping_city_town":"Chicago","shipping_state_province":"IL","shipping_country"}"

将反斜杠Json转换为普通Json并单独获取的类

dkpilog = dkpiLogService.readDkpiById((long) 70752);

 String request = dkpilog.getApiRequest();
ObjectMapper mapper = new ObjectMapper();
Dkpi readValue1 = mapper.readValue(request1, Dkpi.class);


if (readValue1!= null) {
                firstName = readValue1.getUserName();
                msg = readValue1.getMessageId();
            }
            System.out.println("firstname - " + firstName + "msg - " + msg);

来自DB的Json数据

\"billing_street_address\":\"\",
\"billing_street_address_2\":\"\",
\"billing_city_town\":\"\",
\"billing_state_province\":\"\",
\"billing_country\":\"\",
\"billing_postal_code\":\"\",
\"shipping_street_address\":\"7047 N Ashland Blvd\",
\"shipping_street_address_2\":\"\",
\"shipping_city_town\":\"Chicago\",
\"shipping_state_province\":\"IL\",
\"shipping_country\":\"US\",

pojo类可以安全地存储json

public class Dkpi {

@JsonProperty("billing_street_address")
    private String billingStreetAdd;

    @JsonProperty("billing_street_address_2")
    private String billingStreetAdd2;

    @JsonProperty("billing_city_town")
    private String billingCityTown;

    @JsonProperty("billing_state_province")
    private String billingStatePro;

    @JsonProperty("billing_country")
    private String billingCountry;

    @JsonProperty("billing_postal_code")
    private String billingPosCode;

    @JsonProperty("shipping_street_address")
    private String shippingStreetAdd;

    @JsonProperty("shipping_street_address_2")
    private String shippingStreetAdd2;

    @JsonProperty("shipping_city_town")
    private String shippingCityTown;

    @JsonProperty("shipping_state_province")
    private String shippingStatePro;

    @JsonProperty("shipping_country")
    private String shippingCountry;


 public String getBillingStreetAdd() {
        return billingStreetAdd;
    }

    public void setBillingStreetAdd(String billingStreetAdd) {
        this.billingStreetAdd = billingStreetAdd;
    }

    public String getBillingStreetAdd2() {
        return billingStreetAdd2;
    }

    public void setBillingStreetAdd2(String billingStreetAdd2) {
        this.billingStreetAdd2 = billingStreetAdd2;
    }

    public String getBillingCityTown() {
        return billingCityTown;
    }

    public void setBillingCityTown(String billingCityTown) {
        this.billingCityTown = billingCityTown;
    }

    public String getBillingStatePro() {
        return billingStatePro;
    }

    public void setBillingStatePro(String billingStatePro) {
        this.billingStatePro = billingStatePro;
    }

    public String getBillingCountry() {
        return billingCountry;
    }

    public void setBillingCountry(String billingCountry) {
        this.billingCountry = billingCountry;
    }

    public String getBillingPosCode() {
        return billingPosCode;
    }

    public void setBillingPosCode(String billingPosCode) {
        this.billingPosCode = billingPosCode;
    }

    public String getShippingStreetAdd() {
        return shippingStreetAdd;
    }

    public void setShippingStreetAdd(String shippingStreetAdd) {
        this.shippingStreetAdd = shippingStreetAdd;
    }

    public String getShippingStreetAdd2() {
        return shippingStreetAdd2;
    }

    public void setShippingStreetAdd2(String shippingStreetAdd2) {
        this.shippingStreetAdd2 = shippingStreetAdd2;
    }

    public String getShippingCityTown() {
        return shippingCityTown;
    }

    public void setShippingCityTown(String shippingCityTown) {
        this.shippingCityTown = shippingCityTown;
    }

    public String getShippingStatePro() {
        return shippingStatePro;
    }

    public void setShippingStatePro(String shippingStatePro) {
        this.shippingStatePro = shippingStatePro;
    }

    public String getShippingCountry() {
        return shippingCountry;
    }

    public void setShippingCountry(String shippingCountry) {
        this.shippingCountry = shippingCountry;
    }
}

我希望将Json数据转换为java对象POJO，以便将它们分别保存在各自的列中。
