想要将json对象映射到java对象

String . json输出为字符串: {"result":{"number":"INC0022500"}} .

result .

Gson gson = new Gson();
EspIncidentTrial staff = gson.fromJson(json, EspIncidentTrial.class);

ESPIncidentTrial课程:

import javax.persistence.Embeddable;

import org.codehaus.jackson.annotate.JsonIgnoreProperties;
import org.codehaus.jackson.annotate.JsonProperty;

@Embeddable
@JsonIgnoreProperties(ignoreUnknown = true)
public class EspIncidentTrial {
    @JsonProperty("result")
    private ResultTrial result;

    public ResultTrial getResult() {
        return result;
    }

    public void setResult(ResultTrial result) {
        this.result = result;
    }

}

ResultTrial . 下面是正文。

结果分类:

import javax.persistence.Embeddable;

import org.codehaus.jackson.annotate.JsonIgnoreProperties;
import org.codehaus.jackson.annotate.JsonProperty;

@Embeddable
@JsonIgnoreProperties(ignoreUnknown = true)
public class ResultTrial {
    @JsonProperty("number")
    private String incidentId;

    public String getIncidentId() {
        return incidentId;
    }

    public void setIncidentId(String incidentId) {
        this.incidentId = incidentId;
    }
}

现在发生的是 EspIncidentTrial 后果 结果试验 类,没有进行映射。

后果 在json对象中作为字符串,但抛出了以下错误,这是意料之中的。

The error occured while parsing the JSON. com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 12 path $.result

请帮忙!
