我试图通过Hibernate用随机数据填充DB表。
但是我的代码向表中填充不兼容的数据（不完全是不兼容，它是在枚举中声明的元素的索引，例如：在ApartmentState中，FREE是第一个元素，它被设置为适当列的索引-0。 但我想要将FREE作为枚举或字符串放入）。
我无法确定为什么会出现这种情况。
以下是代码片段：
private List<Apartment> generateApartments() {
for (int i = 1; i <= 3; i++) {
for (int j = 2; j <= 5; j++) {
Apartment apartment = new Apartment();
// fill apartment
apartment.setRoomName(generateRoomName());
apartment.setPricePerHour(generatePrice());
apartment.setApartmentState(FREE);
apartment.setRating(getDesiredRating(j));
apartment.setSleepPlaces(getDesiredPlaces(i));
apartment.setActive(true);
// save apartment
apartments.add(apartment);
}
}
return apartments;
}
private Apartment.SleepPlaces getDesiredPlaces(int i) {
switch (i) {
case 1:
return ONE_PLACE;
case 2:
return TWO_PLACES;
case 3:
return THREE_PLACES;
}
return ONE_PLACE;
}
private Apartment.StarRating getDesiredRating(int j) {
switch (j) {
case 2:
return TWO_STARS;
case 3:
return THREE_STARS;
case 4:
return FOUR_STARS;
case 5:
return FIVE_STARS;
}
return TWO_STARS;
}
我需要在表格中填写一些枚举值，例如评级（2、3、4）和睡眠场所（1、2..）。但这会向表格中添加一些错误的数据。
这是工作台上的内容：
为什么它只将索引放入表格，而不是字符串或枚举类型。如何在未来恢复到期望的值。
这是公寓类的代码片段：
@Entity
@Table(name = "Apartments")
public class Apartment extends AbstractEntity implements Comparable<Apartment> {
private Integer id;
private String roomName;
private Double pricePerHour;
private ApartmentState apartmentState;
private StarRating rating;
private SleepPlaces sleepPlaces;
private Boolean active;
public enum ApartmentState {
FREE, REQUESTED, BOOKED, LIVED, CLEANING, PROCESSING
}
public enum StarRating {
TWO_STARS("2 stars"), THREE_STARS("3 stars"), FOUR_STARS("4 stars"), FIVE_STARS("5 stars");
private String description;
private StarRating(String description) {
this.description = description;
}
public String getDescription() {
return description;
}
}
public enum SleepPlaces {
ONE_PLACE("1 person"), TWO_PLACES("2 persons"), THREE_PLACES("3 persons"), FOUR_PLACES("4 persons");
private String count;
private SleepPlaces(String count) {
this.count = count;
}
public String getCount() {
return count;
}
}
对我来说，最好的方法是将枚举类型作为枚举本身（可能在MySql Workbench中）或作为字符串（并使用Enum类中的name()和valueOf()函数）进行存储。
但是如何在Hibernate中实现呢？
如何解决这个问题？
