Question

我正在尝试使用spring JPA存储库

在oracle DB中插入数据

我有一个哈希映射，其中包含需要填充到DB中的所有值，我正在迭代每个值并设置到我的Entity类中基本上我有一个具有复合主键（NotifiedToId）的表。当我设置值ints抛出约束违规异常。在我的日志中它打印所有正确的值，但它没有插入，

我的实体课程：

@Embeddable
public class TbBamiNotifUserLogPK implements Serializable {
//default serial version id, required for serializable classes.
private static final long serialVersionUID = 1L;

@Column(name="NOTIF_REF_NO")
private String notifRefNo;

@Column(name="NOTIFIED_TO_ID")
private String notifiedToId;

public TbBamiNotifUserLogPK() {
}
public String getNotifRefNo() {
    return this.notifRefNo;
}
public void setNotifRefNo(String notifRefNo) {
    this.notifRefNo = notifRefNo;
}
public String getNotifiedToId() {
    return this.notifiedToId;
}
public void setNotifiedToId(String notifiedToId) {
    this.notifiedToId = notifiedToId;
}

public boolean equals(Object other) {
    if (this == other) {
        return true;
    }
    if (!(other instanceof TbBamiNotifUserLogPK)) {
        return false;
    }
    TbBamiNotifUserLogPK castOther = (TbBamiNotifUserLogPK)other;
    return 
        this.notifRefNo.equals(castOther.notifRefNo)
        && this.notifiedToId.equals(castOther.notifiedToId);
}

public int hashCode() {
    final int prime = 31;
    int hash = 17;
    hash = hash * prime + this.notifRefNo.hashCode();
    hash = hash * prime + this.notifiedToId.hashCode();

    return hash;
}

}

业务逻辑：

        try{    
            notificationlog.setNotifRefNo("121323");
            notificationlog.setRefno(refNum);
            notificationlog.setVersion(new BigDecimal(1));
            notificationlog.setAction(action);
            LOGGER.debug("TEMPLATE TYPE"+entry.getValue().getTemplate_type());
            LOGGER.debug("TEMPLATE"+entry.getValue().getTemplate());
            notificationlog.setNotifType(entry.getValue().getTemplate_type());
            notificationlog.setNotifContent(entry.getValue().getTemplate());
            notificationlog.setNotifiedDateTime(notifiedDateTime);
            tbBamiNotifyLogRepository.save(notificationlog);

            LOGGER.debug("inside if block ::: ");
            LOGGER.debug("USERID is: "+entry.getValue().getUserID());

            LOGGER.debug("NOTIFROLE is: "+entry.getKey());
            tbBamiNotifUserLogPK.setNotifiedToId(entry.getValue().getUserID());
            tbBamiNotifUserLogPK.setNotifRefNo("121323");
            tbBamiNotifUserLog.setId(tbBamiNotifUserLogPK);

            LOGGER.debug("GET is: "+tbBamiNotifUserLog.getId().getNotifiedToId());

            tbBamiNotifUserLog.setNotifiedToRole(entry.getKey());
            tbBamiNotifyUserLogRepository.save(tbBamiNotifUserLog);

尝试在保存开始时添加notificationlog = new TbBamiNotificationLog()。当您尝试保存第二行但实例是相同的时（第一次保存期间提供了id），这是可能的。
