Question

我正在尝试更新名为PartnerPIDInfo的表中的列，用下面的代码：

private HashMap<String, String> insertPartnerPIDInfoEntries(String 
partnerId, String environment, List<PartnerPidEntity> partnerPidInfoEntries, 
String user) {
    HashMap<String, String> resultMap = new HashMap<>();

    for (PartnerPidEntity partnerPidInfoEntry : partnerPidInfoEntries) {
        logger.info("PartnerPidEntity entry:{}", partnerPidInfoEntry);
        //String key = partnerPidInfoEntry.getPartnerId() +"|"+ 
       partnerPidInfoEntry.getPID();
        partnerPidInfoEntry.setPartnerId(partnerId);
        String key = partnerPidInfoEntry.getPartnerId()+"|"+ 
        partnerPidInfoEntry.getBannerOMSPid();
        logger.info("PartnerPidEntity Key:" + key);
        try {
            partnerPidInfoEntry.fillDefaultField();
            omsdbReadWriteWrapper.insertPartnerPidInfoEntry(environment, 
            partnerPidInfoEntry);
            resultMap.put(key,"Success");
        } catch (Exception e) {
            logger.error("Exception writing into PartnerPidEntity:" + 
             e.getMessage());
            resultMap.put(key,"Failed");
        }
    }
    return resultMap;
}

PartnerPidEntity类：

 @Entity
 @Table(name = "dbo.PartnerPIDInfo", schema = "", catalog = "Coupons")
 public class PartnerPidEntity implements Serializable{
 private static final long serialVersionUID = 1L;


 private String partnerId;
 private Integer bannerPid;
 private Timestamp createDate;
 private Boolean isActive;

@Id
 @Column(name = "PartnerId", nullable = false, length = 64)
 public String getPartnerId() {
 return partnerId;
  }

 public void setPartnerId(String partnerId) {
 partnerId = partnerId;
 }

@Id
 @Column(name = "PID", nullable = false, length = 20)
 public Integer getBannerOMSPid() {
 return bannerPid;
  }

 public void setBannerOMSPid(Integer bannerPid) {
 this.bannerPid = bannerPid;
 }

 @Basic
 @Column(name = "CreateDate", nullable = false, length = 20)
 public java.sql.Timestamp getCreateDate() {
 return createDate;
 }

 public void setCreateDate(java.sql.Timestamp createDate) {
  this.createDate = createDate;
  }

@Basic
@Column(name = "IsActive", nullable = false,  length = 10)
 public Boolean getIsActive() {
return isActive;
}

 public void setIsActive(Boolean isActive) {
   this.isActive = isActive;
  }
 public PartnerPidEntity fillDefaultField(){
this.createDate = new java.sql.Timestamp(System.currentTimeMillis());
return this;
}
}

在一行partnerPidInfoRepo.save（partnerPIDInfoEntity）; 我最终得到的类不能为null异常。还添加了PartnerPidInfo表的架构：

TABLE "PartnerPIDInfo" (
"PartnerId" VARCHAR(64) NOT NULL,
"PID" INT NOT NULL,
"CreateDate" DATETIME NOT NULL,
"IsActive" BIT NOT NULL,
PRIMARY KEY ("PartnerId", "PID")
)

    return mapPartnerPIDInfoEntity(partnerPIDInfoEntities);
  }

 public void insertPartnerPidInfoEntry(String environment, PartnerPidEntity 
 partnerPIDInfoEntity){
    partnerPidInfoRepo.save(partnerPIDInfoEntity);
   }
  }

请帮助我解决此问题。谢谢

为什么为什么我的Class不能为null异常？
