> ### jsonStr（参数带嵌套list或者多个list）转换成请求参数DTO ###

** 1.【jsonStr参数准备】：**

{
        "memberName":"helloSpark",
        "orgType":1,
        "qualificationReqDTOs":[
            {
                "path":"永宁联社1555465391000.rar",
                "qualificationType":999,
                "fileId":"",
                "dfsPath":"M00/7A/D0/wKi-IVy2hK-AQvSxAF9fcTZlmoU051.rar",
                "dfsFileName":"永宁联社.rar"
            },
            {
                "path":"法人身份证1555491509000.rar",
                "qualificationType":101,
                "fileId":"",
                "dfsPath":"M00/7A/D6/wKi-IVy26rWAAtE-AAzqpCJIMjk573.jpg",
                "dfsFileName":"法人身份证.jpg"
            }
        ],
        "shareholdersReqDTOList":[
            {
                "shareholdersBeneficiaryName":"",
                "shareholdersBeneficiaryCertificatesType":"6",
                "shareholdersCertificatesNumber":"",
                "shareholderCertificatesExpiryDate":"2099-12-31",
                "shareholdersAddress":"股东地址",
                "shareholdersType":"01"
            },
            {
                "shareholdersBeneficiaryName":"",
                "shareholdersBeneficiaryCertificatesType":"0",
                "shareholdersCertificatesNumber":"",
                "shareholderCertificatesExpiryDate":"2026-08-08",
                "shareholdersAddress":"",
                "shareholdersType":"02"
            }
        ]
    }

**注：其中 qualificationReqDTOs和shareholdersReqDTOList两个参数list要和要转换成的DTO参数一致**

**2.【要转换成的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;
    
    /**
     * 请求对象
     *
     * @author nazi email: nazi@baofu.com 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.【转换方法】：**

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依赖】：**

**【jsonStr带String型的Date日期要转换成请求参数DTO的Date型日期】：**

** 在要转换前加上下面两句代码：**

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