springboot升级后@JsonProperty不起作用

问题描述

我最近将我的应用程序从 Spring Boot 1.5.3 升级到 Spring Boot 2.3.5。 UI 上的一项功能开始崩溃，我在调试时发现对 UI 的 json 响应发生了变化

原回复：

"modelExplanation": [{
                                "sectionId": 0,"sectionText": "some text","startIndex": "0","endIndex": "105","modelExplanations": [{
                                                "modelId": "mdl_collusion","modelName": "collusion","modelVersion": "3.4.1","score": "1.0","riskStatus": "low"
                                },{
                                                "modelId": "mdl_mkt_mnpltn","modelName": "market_manipulation",{
                                                "modelId": "mdl_secrecy","modelName": "secrecy","riskStatus": "low"
                                }]
                }]
}

新回复：在属性名称中有下划线 (_)

                                "section_id": 1,"section_text": "some text","start_index": "738","end_index": "1112","model_explanations": [{
                                                "model_id": "mdl_collusion","model_name": "collusion","model_version": "3.4.1","section_score": "0.09059832","risk_status": "low"
                                },{
                                                "model_id": "mdl_mkt_mnpltn","model_name": "market_manipulation","section_score": "0.12787165",{
                                                "model_id": "mdl_secrecy","model_name": "secrecy","section_score": "0.19208406","risk_status": "low"
                                }]
                }]
}

似乎@JsonProperty 不起作用。我的课程如下：

  public ModelExplanationResponse getModelExplanation(User user,ModelRequest request) {
    ModelExplanationMetadata metadata = null;
    try {
        String modelExplanationJson = anotherService.getModelExplanation(user,request.getMessageId(),request.getSource(),request.getAvroId(),request.getRundate());
        
        if (modelExplanationJson != null && !"".equals(modelExplanationJson)) {
            metadata = mapJSONToMetadata(modelExplanationJson);
        }
    } catch (Exception e) {
        throw new AlertMngtServiceException("Unable to retrieve attachment",e);
    }
    return getModelExplanationResponse(metadata,request);
}

private ModelExplanationResponse getModelExplanationResponse(ModelExplanationMetadata metadata,ModelRequest request) {
    ModelExplanationResponse response = new ModelExplanationResponse();
    if (metadata != null && metadata.getModelExplanation() != null) {
        List<ModelExplanationSection> modelExplanation = mapJSONToModelExplanation(metadata.getModelExplanation());
        if (!CollectionUtils.isEmpty(modelExplanation)) {
            modelExplanation.sort(Comparator.comparing(ModelExplanationSection::getSectionId));
            response.setModelExplanation(modelExplanation);
            String formattedMessageBody = new ModelExplanationBasedMessageModifier().modify(request.getMessageBody(),modelExplanation);               
            response.setMessageBody(formattedMessageBody);
        }
    } else {
        LOGGER.info("Unable to fetch Model Explanation for {}",request);
    }
    return response;
}


import com.fasterxml.jackson.annotation.JsonCreator;

public class ModelExplanationSection {

    private final int sectionId;
    private final String sectionText;
    private final String startIndex;
    private final String endIndex;
    private final List<ModelExplanation> modelExplanations;

    @JsonCreator

        super();
        this.sectionId = sectionId;
        this.sectionText = sectionText;
        this.startIndex = startIndex;
        this.endIndex = endIndex;
        this.modelExplanations = modelExplanations;
    }

    public int getSectionId() {
        return sectionId;
    }

    public String getSectionText() {
        return sectionText;
    }

    public String getStartIndex() {
        return startIndex;
    }

    public String getEndIndex() {
        return endIndex;
    }

    public List<ModelExplanation> getModelExplanations() {
        return modelExplanations;
    }

}




import com.fasterxml.jackson.annotation.JsonCreator;

import com.fasterxml.jackson.annotation.JsonProperty;
import com.google.common.base.Strings;

@JsonIgnoreProperties(ignoreUnknown = true)
public class ModelExplanation {

    private final String modelId;
    private final String modelName;
    private final String modelVersion;
    private final String score;
    private final String riskStatus;

    @JsonCreator
    public ModelExplanation(
            @JsonProperty("model_id") String modelId,@JsonProperty("model_name") String modelName,@JsonProperty("model_version") String modelVersion,@JsonProperty("section_score") String score,@JsonProperty("risk_status") String riskStatus) {
        super();
        this.modelId = modelId;
        this.modelName = modelName;
        this.modelVersion = modelVersion;
        this.score = score;
        this.riskStatus = getRiskStatus(riskStatus);
    }

    private String getRiskStatus(String riskStatus) {
        return Strings.isNullOrEmpty(riskStatus)?"low":riskStatus;
    }

    public String getModelId() {
        return modelId;
    }

    public String getModelName() {
        return modelName;
    }

    public String getModelVersion() {
        return modelVersion;
    }

    public String getScore() {
        return score;
    }

    public String getRiskStatus() {
        return riskStatus;
    }

}

我试过@JsonCreator(mode = JsonCreator.Mode.PROPERTIES) 但它不起作用。 在 stack-overflow 上找到了另一个解决方案，建议将 jackson 注释导入替换为 org.codehaus.jackson.annotate，但这对我也不起作用。

这里使用相同的类有两个目的，1. @JsonProperty 用于将 json 响应从 anotherService 映射到 java 对象，然后使用相同的 java 对象将 java 对象序列化为 ui。我无法理解在升级之前它是如何工作的。

非常感谢任何帮助，因为这已经花了一天的时间，但我还无法识别和解决问题。
