这是我的实体角色类
@Entity
@AllArgsConstructor
@NoArgsConstructor
@Data
public class Role implements GrantedAuthority {
@Id
@GeneratedValue
private Integer id;
@Column()
private RoleName roleName;
@Override
public String getAuthority() {
return roleName.name();
}
}
这是我的RoleName类
public enum RoleName {
ROLE_USER,
ROLE_ADMIN,
ROLE_DIRECTOR
}
如果我查看数据库,我会看到role_name列的类型是integer????当我编写查询时
insert into role(id, role_name)
values(1, 'ROLE_USER'),
(2, 'ROLE_ADMIN'),
(3, 'ROLE_DIRECTOR');
它会显示错误消息“integer类型的语法无效:“ROLE_USER”您能帮助我如何解决此问题吗?为什么role_name列在给予其类型枚举时是整数?这是一条错误消息

我已尝试使用双引号给出查询
insert into role(id, role_name)
values(1, "ROLE_USER"),
(2, "ROLE_ADMIN"),
(3, "ROLE_DIRECTOR");
但它给出了另一个错误消息“列'ROLE_USER'不存在“
我期待一个为什么role_name是整数以及如何给予列类型指定枚举的原因
2条答案
按热度按时间b4qexyjb1#
你的
role_name
是一个整数,因为你没有把它创建成字符串。如果希望数据库中的枚举值是字符串,则必须将此注解添加到字段中
有关详细信息,请查看以下链接:https://www.baeldung.com/jpa-persisting-enums-in-jpa

以下三个步骤来解决变更
更改数据库
然后尝试插入数据库
最后但同样重要的是,更改实体列
