Question

我在 mysql 中使用休眠 4.3.7。我无法在 mysql 中坚持 joda tiem。当我使用这个注解时 @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTimeWithZone")，它抛出这个异常

property mapping has wrong number of columns: car.modifiedDate type: org.jadira.usertype.dateandtime.joda.PersistentDateTimeWithZone

实体class：

  @Entity
 public class Car implements Serializable {
private static final long serialVersionUID = 1L;

/**
 */

@Column(name = "CAR_ID", nullable = false,length = 50)
@Basic(fetch = FetchType.EAGER)
@Id
@XmlElement
String carId;
/**
 */

@Column(name = "CAR_NAME", length = 50)
@Basic(fetch = FetchType.EAGER)
@XmlElement
String carName;

/**
 */

@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTimeWithZone")
@Column(name = "DATE_CREATED")
@Basic(fetch = FetchType.EAGER)
@XmlElement
DateTime dateCreated;


@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTimeWithZone")
@Column(name = "DATE_MODIFIED")
@Basic(fetch = FetchType.EAGER)
@XmlElement
DateTime modifiedDate;
/**
 */


@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@JoinColumn(name="MCR_CAR_ID", nullable=false, insertable=false, updatable=false)
java.util.Set<MainCar> mainCar;

//setters and getters
 }

问题可能是您数据库中的 dateCreated 和 modifiedDate 列是 DateTime 类型，但您的代码保存为带区域的 DateTime。您能否尝试将 dateCreated 和 modifiedDate 类型编辑为 org.jadira.usertype.dateandtime.joda.PersistentDateTime，如下所示：

@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
@Column(name = "DATE_CREATED")
@Basic(fetch = FetchType.EAGER)
@XmlElement
DateTime dateCreated;


@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
@Column(name = "DATE_MODIFIED")
@Basic(fetch = FetchType.EAGER)
@XmlElement
DateTime modifiedDate;

如果你想用 Zone 保存 DateTime，那么你必须将你的 @Type 修改为：

  @Type(type="org.jadira.usertype.dateandtime.joda.PersistentDateTime",
            parameters = { @Parameter(name = "databaseZone", value = "UTC"),
                 @Parameter(name = "javaZone", value = "jvm")})
        @Column(name = "DATE_MODIFIED")
        @Basic(fetch = FetchType.EAGER)
        @XmlElement
        DateTime modifiedDate;
