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ModelMapper将其传递给DocumentDto类: DocumentDto documentDto = modelMapper.map(documentToSignRestRequest，DocumentDto.class)；

这个类的不同属性与组成我要映射的类的不同类具有相同的名称。

@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postman时，我得到一条错误消息：

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

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;
}
