ModelMapper配置错误

Question

我有一个JSON：

{
    "signatureOptions": {
        "signatureType": "string",
        "digestAlgorithmName": "string",
        "signaturePackagingType": "string",
        "documentType": "string"
       },
    "pdfSignatureOptions": {
        "signatureTextColor": integerValue,
        "signatureTextFontSize": floatValue,
        "fontFamily": "string",
        "fontStyle": "string",
        "signatureImageContent": "string",
        "signatureText": "string",
        "signaturePosX": floatValue,
        "signaturePosY": floatValue,
        "signaturePage": integerValue
       },
       "enableArchive": false,
       "archiverNames": [
        "string"
       ],
    "toSignContent": "String"
}

我创建了以下pojo

@Getter @Setter
public class SignatureOptions {
    private String signatureType;
    private String digestAlgorithmName;
    private String signaturePackagingType;
    private String documentType;

    // constructor
}

@Getter @Setter
public class PdfSignatureOptions {
    private int signatureTextColor;
    private float signatureTextFontSize;
    private String fontFamily;
    private String fontStyle;
    private String signatureImageContent;
    private String signatureText;
    private float signaturePosX;
    private float signaturePosY;
    private int signaturePage;

    // constructor
}

@Getter @Setter
public class DocumentToSignRestRequest {
    private SignatureOptions signatureOptions = new SignatureOptions();
    private PdfSignatureOptions pdfSignatureOptions = new PdfSignatureOptions();
    private boolean enableArchive;
    private ArrayList< Object > archiverNames = new ArrayList <>();
    private String toSignContent;

    // constructor
}

在我的控制器中，我有一个@PostMapping方法，我尝试检索DocumentToSignRestRequest：

@PostMapping(
    value="/sign",
    consumes = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE },
    produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE }
)
public DocumentRest getDocumentSigned(@RequestBody DocumentToSignRestRequest  documentToSignRestRequest) throws Exception {
    // instanciate empty return object
    DocumentRest returnValue = new DocumentRest();

    // Map the documentToSignRestRequest with a DTO Object
    ModelMapper modelMapper = new ModelMapper();
    DocumentDto documentDto = modelMapper.map(documentToSignRestRequest, DocumentDto.class);

    // Call the documentService layer and assign the return to a new DOcumentDto
    DocumentDto signedDocument = documentService.signDocument(documentDto);
    returnValue = modelMapper.map(signedDocument, DocumentRest.class);
    // return a rest object with signedDocument values
    return returnValue;
}

并使用模型映射器将其传递给DocumentDto类：DocumentDto DocumentDto=ModelMapper。地图（documentToSignRestRequest，DocumentDto.class）；

这个类的不同属性与组成我要映射的类的不同类中的属性具有相同的名称。

@Getter @Setter
public class DocumentDto implements Serializable {

    @Getter(AccessLevel.NONE)
    @Setter(AccessLevel.NONE)
    private static final long serialVersionUID = 6835192601898364280L;

    // document information from DocumentRest
    private String documentName;
    private String documentPath;
    private boolean isDocumentSigned;
    // SignatureOptions values
    private String signatureType;
    private String digestAlgorithmName;
    private String signaturePackagingType;
    private String documentType;
    // PdfSignatureOptionsObject values
    private int signatureTextColor;
    private float signatureTextFontSize;
    private String fontFamily;
    private String fontStyle;
    private String signatureImageContent;
    private String signatureText;
    private float signaturePosX;
    private float signaturePosY;
    private int signaturePage;

    private boolean enableArchive;
    private ArrayList< Object > archiverNames = new ArrayList <>();
    private String toSignContent;
}

当我使用邮递员时，我收到一条错误消息：

ModelMapper配置错误：\r\n\r\n1）目标属性com.app.ws.certeuropews.shared.dto.DocumentDto.setSignatureType（）匹配多个源属性层次结构：\n\n\tcom.app.ws.certeuropews.ui.model.request.DocumentToSignRestRequest.getSignatureOptions（）/

这个问题的解决方案是什么。我在看ModelMapper指南，我想知道。。http://modelmapper.org/examples/projection/#example-1

Answer 1

我没有正确设置DTO层：

@Getter
@Setter
public class DocumentDto implements Serializable {

    @Getter(AccessLevel.NONE)
    @Setter(AccessLevel.NONE)
    private static final long serialVersionUID = 6835192601898364280L;

    // document information from DocumentRest
    private String documentName;
    private String documentPath;
    private boolean isDocumentSigned;
    // SignatureOptions values
    private SignatureOptionsDto signatureOptionsDto;
    // PdfSignatureOptionsObject values
    private PdfSignatureOptionsDto pdfSignatureOptionsDto;

    private boolean enableArchive;
    private ArrayList< Object > archiverNames = new ArrayList <>();
    private String toSignContent;
}
