Spring 将 nvarchar 转换为 bigint 时出错

Question

每当我尝试保存对象时都会遇到错误。

导致错误的字段是 string 映射到数据库中的 varchar(200)。
该字段的名称是 localContact.

这是我的代码：

Site.java:

@Entity
@Table(name = "SITE", uniqueConstraints = { @UniqueConstraint(columnNames = { "SITE_COUNTRY_ID", "SITE_NAME" }) })
@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED, withModifiedFlag = true)
public class Site implements ISite {

/** The Constant serialVersionUID. */
private static final long serialVersionUID = -390717603276436784L;

/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "SITE_ID", unique = true, nullable = false)
private long id;

/** The site address. */
@Column(name = "SITE_ADDRESS", length = BusinessConstants.SITE_ADDRESS)
private String address;

/** The site analog phone number. */
@Column(name = "SITE_ANALOG_PHONE_NUMBER", length = BusinessConstants.SITE_ANALOG_PHONE_NUMBER)
private String analogPhoneNumber;

/** The site comment. */
@Column(name = "SITE_COMMENT", length = BusinessConstants.SITE_COMMENT)
private String comment;

/** The site entity code. */
@Digits(integer = 3, fraction = 0, message = "Please enter max 3 digits")
@Column(name = "SITE_ENTITY_CODE", nullable = false)
private long entityCode;

/** The site invoice code. */
@Digits(integer = 10, fraction = 0, message = "Please enter max 10 digits")
@Column(name = "SITE_INVOICE_CODE", nullable = false)
private long invoiceCode;

/** The site local it phone. */
@Column(name = "SITE_LOCAL_IT_PHONE", length = BusinessConstants.SITE_LOCAL_IT_PHONE)
private String localItPhone;

/** The site name. */
@NotBlank
@Column(name = "SITE_NAME", nullable = false, length = BusinessConstants.SITE_NAME)
private String siteName;

/** The site subnet. */
@NotBlank
@Column(name = "SITE_SUBNET", nullable = false, length = BusinessConstants.SITE_SUBNET)
private String subnet;

/** The site user number. */
@Digits(integer = 4, fraction = 0, message = "Please enter max 4 digits")
@Column(name = "SITE_USER_NUMBER")
private Long userNumber;

/** The business. */
@Valid
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "SITE_BUSINESS_ID", nullable = false)
private Business business;

/** The country. */
@Valid
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "SITE_COUNTRY_ID")
private Country country;

/** The local contact. */
@Column(name = "SITE_LOCAL_CONTACT", nullable = true, length = BusinessConstants.LOCAL_CONTACT)
private String localContact; //the field that cause the error

/** The local it. */
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "SITE_LOCAL_IT", nullable = true)
private User localIt;

/** The rif. */
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "SITE_RIF", nullable = true)
private User rif;

/** The status. */
@Valid
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "SITE_STATUS_ID", nullable = false)
private Status status;

/** The end date. */
@Column(name = "SITE_END_DATE")
@Temporal(TemporalType.TIMESTAMP)
@DateTimeFormat(iso = ISO.DATE_TIME)
private Date endDate = null;

@ManyToMany(targetEntity = User.class, mappedBy = "userSites", fetch = FetchType.LAZY)
@NotAudited
private Set<IUser> siteUsers;

/**
 * Gets the local contact.
 *
 * @return the local contact
 */
public String getLocalContact() {
    return this.localContact;
}

/**
 * Sets the local contact.
 *
 * @param localIt the new local contact
 */
public void setLocalContact(String localContact) {
    this.localContact = localContact;
}

我的 jsp :

<td class="label"><spring:message code="site.localcontact" /></td>
        <td class="value">
            <form:input path="site.localContact"></form:input>
        </td>

我的 DAO：

public void saveSite(ISite siteObj){
    Assert.notNull(siteObj);
    merge((Site) siteObj);
}

编辑

抛出的错误是：

Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Error converting data type nvarchar to bigint

我发现了错误，

我有另一个 table 为我的站点创建一个名为 SITE_AUD 的历史记录，其中的字段 SITE_LOCAL_CONTACT 是一个 bigint。
