Spring Hibernate - getLong（）的值无效 - 'United Kingdom - UTC +0：00'

Question

我想hibernate试图将从数据库中取出的String值分配给long.Have做了多对一的单向映射。我试图在CorporateGroupForm.jsp的下拉列表中显示region表中的值

CorporateGroup.java

    @Entity
    @Table(name="corporate_group")
    public class CorporateGroup extends BaseObject implements Serializable {
     private Region region;
     private Long id;

    @ManyToOne(cascade=CascadeType.ALL)
    @JoinColumn(name="id")
    public Region getRegion() {
    return region;
   }
    public void setRegion(Region region) {
    this.region = region;
    }

  @Id 
  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column(name="id")
  public Long getId() {
    return id;
  }
  public void setId(Long id) {
    this.id = id;
  } }

corporateGroupForm.jsp

    <li>
    <appfuse:label styleClass="desc" key="corporateGroupDetail.region"/>
    <select name="regionDesc">
        <option value=""><fmt:message key="select.pleaseSelect"/></option>
    <c:forEach var="region" items="${regionsList}">
            <c:set var="selected" value="${corporateGroup.region ne null and corporateGroup.region.regionDesc eq region.regionDesc}"/>
         <option ${selected ? 'selected' : ''} value="${region.regionDesc }">${region.regionDesc } </option> 
        </c:forEach>
    </select>
</li>

DB：

    CREATE TABLE `corporate_group` (`id` bigint(20) NOT NULL AUTO_INCREMENT,`comment` text,`name` varchar(255) NOT NULL,`parent_id`bigint(20) DEFAULT NULL,`primary_contact_id` bigint(20) DEFAULT NULL,`account_manager_email` varchar(255) DEFAULT NULL,`dateCreated` datetime DEFAULT CURRENT_TIMESTAMP,`region_description` varchar(255) DEFAULT NULL,PRIMARY KEY (`id`),UNIQUE KEY `name` (`name`),KEY `FK61BCC225C8E0340A` (`parent_id`),KEY `FK61BC225F0655E4F` (`primary_contact_id`),KEY `FK_REGION_idx` (`region_description`),CONSTRAINT `fk_region` FOREIGN KEY (`region_description`) REFERENCES `region` (`region_description`) ON DELETE NO ACTION ON UPDATE NO ACTION,CONSTRAINT `FK61BC225F0655E4F` FOREIGN KEY (`primary_contact_id`) REFERENCES `app_user` (`id`),CONSTRAINT `FK61BCC225C8E0340A` FOREIGN KEY (`parent_id`) REFERENCES `corporate_group` (`id`)) ENGINE=InnoDB AUTO_INCREMENT=843 DEFAULT CHARSET=latin1;

异常堆栈跟踪：

Region.java

    @Entity
    @Table(name = "region")
    public class Region extends BaseObject implements Serializable {
private static final long serialVersionUID = 1L;

private Long id;
@Id 
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="id")
public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

private String countryCode;
private String countryName;
private String timeZone;
private String regionDesc;

@Column(name="country_code",nullable=false)
public String getCountryCode() {
    return countryCode;
}

public void setCountryCode(String countryCode) {
    this.countryCode = countryCode;
}

@Column(name="country_name",nullable=false)
public String getCountryName() {
    return countryName;
}

public void setCountryName(String countryName) {
    this.countryName = countryName;
}
@Column(name="time_zone",nullable=false)
public String getTimeZone() {
    return timeZone;
}

public void setTimeZone(String timeZone) {
    this.timeZone = timeZone;
}

@Column(name="region_description",nullable=false)
public String getRegionDesc() {
    return regionDesc;
}

public void setRegionDesc(String regionDesc) {
    this.regionDesc = regionDesc;
}
@Override
public String toString() {
    StringBuffer strBuff = new StringBuffer();
    if (getId() != null) {
        strBuff = strBuff.append("ID:" + getId() + ",");
        strBuff = strBuff.append("Country Name:" + getCountryName() + ",");
        strBuff = strBuff.append("Country Code:" + getCountryCode() + ",");
        strBuff = strBuff.append("Timezone:" + getTimeZone() + ",");
        strBuff = strBuff.append("Region Description:" + getRegionDesc() + ",");
    }

    return strBuff.toString();
}

@Override
public boolean equals(Object o) {
    // TODO Auto-generated method stub
    if (!(o instanceof Region)) {
        return false;
    }
    Region reg = (Region) o;

    return !(regionDesc != null ? !regionDesc.equals(reg.getRegionDesc()) : reg.getRegionDesc() != null);
}

@Override
public int hashCode() {
    // TODO Auto-generated method stub
    int hashcode = 0;
    if (this.regionDesc != null) {
        hashcode = hashcode + this.regionDesc.hashCode();
    }

    return hashcode;
}

}

现在出现了另一个错误：

Answer 1

在CorporateGroup实体类中，您使用region_description Region实体映射了一个主键为Long的实体

@ManyToOne(cascade=CascadeType.ALL,fetch=FetchType.EAGER)
    @JoinColumn(name="region_description") 
    public Region getRegion() { 
      return region; 
    }

您可以做的是将CorporateGroup的区域成员变量映射到Region实体类的主键，而不是region_description。

关于此错误：

  

实体映射中的重复列：   com.canvas8.model.CorporateGroup列：id（应映射为   插入=＆＃34;假＆＃34;更新=＆＃34;假＆＃34）

错误信息很明显，您已将同一列映射两次。请参阅this并解决问题。

希望这有帮助！

Answer 2

我能够指定引用的列名来为我解决问题。我不想急于获取实体，因为它有时仅会使用并且没有修改数据库架构的权限。

尝试一下：

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "region_description", referencedColumnName = "region_description")
private Region region;
