我是休眠注释的新手。我有两张表 Merchant 和 MerchantDeal，我在这些表之间有一个外键。

当我尝试将数据插入 MerchantDeal 表时，正在创建另一列并且没有发生数据插入。

代码是：

Merchant
{

@Id
@Column(name="MERCHANT_ID")
private int iMerchantId;
@Column(name="MERCHANT_NAME")
private String sName;
@Column(name="MERCHANT_CODE")
private int iMerchantCode;
@Column(name="MERCHANT_URL")
private String sUrl;
@Column(name="MERCHANT_DESCRIPTION")
private String sDescription;
@Column(name="MERCHANT_LOGOURL")
private String sLogoUrl;
@Column(name="TERMS")
private String sTerms;
@Column(name="ACTIVE")
private boolean bIsActive;
@Column(name="MERCHANT_EXCLUSIVE")
private boolean bIsExclusive;
@Column(name="TERMS_CONDITIONS")
private String sTermsAndConditions;

@OneToMany(mappedBy="merchant")
private List<MerchantDeal> merchantDeals;

}

MerchantDeal
{

@Id
@Column(name="MERCHANTDEAL_ID")
@GeneratedValue
private int iMerchantDealId;

@OneToOne
@PrimaryKeyJoinColumn
private MerchantDealType oMerchantDealType;

@Column(name="MERCHANTDEAL_DESCRIPTION")
private String sDescription;
@Column(name="MERCHANTDEAL_URL")
private String sMerchantDealUrl;
@Column(name="MERCHANTDEAL_EXCLUSIVE")
private boolean bIsExclusive;
@Column(name="CASHBACKRATE")
private float fCashBackRate;
@Column(name="OFFERTITLE")
private String sOfferTitle;
@Column(name="WITHCASHBACK")
@Type(type="yes_no")
private boolean bIsWithCashBack;
@Column(name="PRINTABLE")
@Type(type="yes_no")
private boolean bIsPrintable;
@Column(name="VOUCHER_CODE")
private String sVoucherCode;
@Column(name="VALID_FROM")
private Date dValidFrom;
@Column(name="VALID_TO")
private Date dValidTo;
@Column(name="PRODUCT_ID")
private int iProductId;
@Column(name="PRODUCTIMAGE_URL")
private String sProductImageUrl;
@Column(name="TOSHOW")
@Type(type="yes_no")
private boolean bToShow;
@Column(name="DEALDELETED_DATE")
private Date dDealDeletedDate;

@ManyToOne
@MapsId
private Merchant merchant;

@Column(name="TERMS")
private String sTerms;

}

这是控制台：

我解决了这个解决方案。实际上问题是在将数据插入到 MerchantDeal 表中时，又创建了一个列。我认为我的“ spring-servlet.xml ”文件中的问题。

我以前的 spring-servlet.xml 是：

......
......
<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="myDataSource" />
        <property name="mappingResources">
            <list>
                <value>Merchant.hbm.xml</value>
                <value>MerchantDeal.hbm.xml</value>
                <value>MerchantDealType.hbm.xml</value>
                <value>CommissionGroup.hbm.xml</value>
                <value>RateType.hbm.xml</value>
                <value>InventoryUnitType.hbm.xml</value>
                <value>PremiumPlacementType.hbm.xml</value><!-- 
                <value>uk.co.wowcher.cashback.domain.beans.PremiumPlacementType</value> -->
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto" >update</prop>
            </props>
        </property>
    </bean>

现在，我刚刚从这段代码中删除了

<prop key="hibernate.hbm2ddl.auto" >update</prop>

spring-servlet.xml 中的行并将@MapsId 替换为@JoinColumn(name="MERCHANT_ID")。现在它按我的意愿工作。
