jsonStr（參數帶嵌套list或者多個list）轉換成請求參數DTO

 1.【jsonStr參數準備】：

{
    "memberName":"helloSpark",
    "orgType":1,
    "qualificationReqDTOs":[
        {
            "path":"永甯聯社1555465391000.rar",
            "qualificationType":999,
            "fileId":"",
            "dfsPath":"M00/7A/D0/wKi-IVy2hK-AQvSxAF9fcTZlmoU051.rar",
            "dfsFileName":"永甯聯社.rar"
        },
        {
            "path":"法人身份證1555491509000.rar",
            "qualificationType":101,
            "fileId":"",
            "dfsPath":"M00/7A/D6/wKi-IVy26rWAAtE-AAzqpCJIMjk573.jpg",
            "dfsFileName":"法人身份證.jpg"
        }
    ],
    "shareholdersReqDTOList":[
        {
            "shareholdersBeneficiaryName":"",
            "shareholdersBeneficiaryCertificatesType":"6",
            "shareholdersCertificatesNumber":"",
            "shareholderCertificatesExpiryDate":"2099-12-31",
            "shareholdersAddress":"股東位址",
            "shareholdersType":"01"
        },
        {
            "shareholdersBeneficiaryName":"",
            "shareholdersBeneficiaryCertificatesType":"0",
            "shareholdersCertificatesNumber":"",
            "shareholderCertificatesExpiryDate":"2026-08-08",
            "shareholdersAddress":"",
            "shareholdersType":"02"
        }
    ]
}
           

注：其中 qualificationReqDTOs和shareholdersReqDTOList兩個參數list要和要轉換成的DTO參數一緻

2.【要轉換成的ReqDTO】：

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
import net.sf.oval.constraint.*;

import java.io.Serializable;
import java.math.BigDecimal;
import java.util.Date;
import java.util.List;

/**
 * 請求對象
 *
 * @author nazi email: [email protected] date:2019/04/01
 */
@Getter
@Setter
@ToString
public class ReqDTO implements Serializable {
    private static final long serialVersionUID = 5954817677490814055L;

    private String memberName;

    private Integer orgType;

    List<ShareholdersReqDTO> shareholdersReqDTOList;

    private List<QualificationReqDTO> qualificationReqDTOs;
}
           

3.【轉換方法】：

import net.sf.json.JSONObject;

ReqDTO reqDTO = new ReqDTO();

JSONObject jsonObj = JSONObject.fromObject(jsonStr);
Map<String, Class> classMap = new HashMap<String, Class>();
classMap.put("shareholdersReqDTOList", ShareholdersReqDTO.class);
classMap.put("qualificationReqDTOs", QualificationReqDTO.class);

reqDTO = (ReqDTO) JSONObject.toBean(jsonObj,
		ReqDTO.class, classMap);
           

【maven依賴】：

<dependency>
	<groupId>net.sf.json-lib</groupId>
	<artifactId>json-lib</artifactId>
	<version>2.2.3</version>
</dependency>        
           

【jsonStr帶String型的Date日期要轉換成請求參數DTO的Date型日期】：

 在要轉換前加上下面兩句代碼：

String[] dateFormats = new String[]{"yyyy-MM-dd"};
 JSONUtils.getMorpherRegistry().registerMorpher(new DateMorpher(dateFormats));
