将JSON解析为自定义POJO，该POJO将Map作为其类成员之一

Question

我有下面的JSON，我想解析到下面的bean类。

{
    "timeStamp": "123123123123",
    "pznFlowFlag": "true",
    "pznRequestFlag": "true",
    "sessionId": "SampleSessionId",
    "ipAddress": "172.148.0.1",
    "offers": [
    {
            "111": {
                "eep" : "44279",
                "spl_ind" : "true"},
            "121": {
                "eep" : "44520",
                "spl_ind" : "false"},
            "333": {
                "eep" : "45419",
                "spl_ind" : "false" }
    }]
}

豆类 1

public class DistributedCookieBean {

    @JsonProperty("timeStamp")
    private String timeStamp;

    @JsonProperty("pznFlowFlag")
    private String pznFlowFlag;

    @JsonProperty("pznRequestFlag")
    private String pznRequestFlag;

    @JsonProperty("sessionId")
    private String sessionId;

    @JsonProperty("ipAddress")
    private String ipAddress;

    @JsonProperty("offers")
    private Map<String, OfferCookieBean> offers = new HashMap<String, OfferCookieBean>();

...<setters & getters>
}

Bean类2

public class OfferCookieBean {

    @JsonProperty("eep")
    private String eep;

    @JsonProperty("spl_ind")
    private String spl_ind;

...<setters & getters>
}

在这里，我无法使用下面的代码解析这些JavaPOJO。

jsonObjMapper.readValue（jsonString，DistributedCookieBean.class）；

堆栈跟踪:

提前致谢！

错误消息指出了问题所在:< code>offers字段被声明为一个map，而在JSON中它是一个map数组。
