java - org.hibernate.AnnotationException : Referenced property not a (One|Many)ToOne:

Question

我正在尝试使用 Hibernate 建立一对一关系。我已尝试按照其他问题的建议进行操作，但仍然遇到问题。

我有一个 Company 类，它有自己的一套仓库规则。每个实体都有一个 BusinessUnitNumber 作为表的 Id。

@Entity(name="COBUSMST")
public class Company implements Serializable{
    private static final long serialVersionUID = 2573441991172174342L;
    private Integer businessUnit;
    private String longName;
    private String shortName;
    private String address1;
    private String address2;
    private String city;
    private String state;
    private String zipCode;
    private String returnAddress1;
    private String returnAddress2;
    private String returnCity;
    private String returnState;
    private String returnZipCode;
    private int phoneNumber;
    private int areaCode;
    private boolean replacementCharge;
    private BigDecimal replacementChargeAmount;
    private String customerServiceKeycode;
    private BigDecimal restockPercent;
    private Integer enterpriseId;
    private String country;
    private String returnCountry;
    private int phoneExtension;
    private String phoneType;

当我尝试运行代码时，出现以下异常:

我唯一能想到的是两个表的 ID 具有相同的列名？但我无法改变这一点，所以我不知道是否有解决方法(如果确实如此)或者我是否遗漏了某些内容。

Answer 1

在Company类中，您注释了一个FIELD (warehouseRules)，但该类中的所有其他人都使用PROPERTY。您应该使用“PROPERTY”或“FIELD”，但不能混合使用。如果您始终如一，您的 JPA 提供商也许会明白这一点？

显然，消息可以更清晰，强调您尚未注释 PROPERTY( setter/getter )。其他 JPA 提供程序不一定坚持使用 OneToOne/OneToMany 注释，因为从属性/字段类型可以清楚地看出它是一种关系。
