java - Hibernate 中所有枚举类型的一张表

Question

我有一个类，假设 Employee 如下；

public class Employee{
    ... Other attributes ...
    @Column @Enumerated(EnumType.Ordinal)
    private Gender gender;

    @Column @Enumerated(EnumType.Ordinal)
    private EmployeeType employeeType;
    ... Getters & Setters ...
}

我的员工表是这样的。

Employee{
    ... other columns ....
    gender int,
    employeetype int,
    ...
}

我有一个通用的查找表查找

Lookups{
    id long,
    lookName String,
    lookId int,
    lookValue String
}

我希望 Hibernate 将 Genders 和 EmployeeTypes 保留在 Lookups 表中，如下所示，我该怎么做；

+--+-------------+---------+------------+ 
|ID|LOOKUPNAME   |LOOKUPID | LOOKUPVALUE|
+--+-------------+---------+------------+
+--+-------------+---------+------------+
|1 | GENDER      | 1       | MALE       |
+--+-------------+---------+------------+ 
|2 | GENDER      | 2       | FEMALE     |
+--+-------------+---------+------------+
|3 | EMPLOYEETYPE| 1       | TEAM MEMBER|
+--+-------------+---------+------------+
|4 | EMPLOYEETYPE| 2       | TEAM LEADER|
+--+-------------+---------+------------+
|5 | EMPLOYEETYPE| 3       | MANAGER    | 
+--+-------------+---------+------------+    

Answer 1

创建 Lookups 类。然后，对于 Employee 类的 Gender 和 EmployeeType 字段，将它们替换为 Lookups 字段。然后删除 Enumerated 注释。
