Spring Data: Enumeration and Repository issue
提问by Manu
I am using Spring Data and Repositories. I created an Entity with a enum type field, which I declared @Enumerated(EnumType.STRING), but I am forced to create a method getAuthority returning a String.
我正在使用 Spring 数据和存储库。我创建了一个带有枚举类型字段的实体，我将其声明为@Enumerated(EnumType.STRING)，但我被迫创建了一个返回字符串的方法 getAuthority。
@Entity
@Configurable
public class BaseAuthority implements GrantedAuthority {
@Enumerated(EnumType.STRING)
@Column(unique = true)
private AuthorityType authority;
@Override
public String getAuthority() {
return authority.toString();
}
}
The enum is as follow:
枚举如下：
public enum AuthorityType {
REGISTEREDUSER, ADMINISTRATOR;
}
In the repository for the entity, I created an operation to find by authority type:
在实体的存储库中，我创建了一个按权限类型查找的操作：
@Repository
public interface BaseAuthorityRepository extends JpaRepository<BaseAuthority, Long> {
BaseAuthority findByAuthority(AuthorityType authority);
}
However, I get a warning:
但是，我收到警告：
Parameter type (AuthorityType) does not match domain class
property definition (String). BaseAuthorityRepository.java
I used to have the operation receiving a String rather than AuthorityType, but that generates a runtime exception. I could change the name of the field authority to authorityType, but I don't like that.
我曾经让操作接收字符串而不是 AuthorityType，但这会生成运行时异常。我可以将字段权限的名称更改为 authorityType，但我不喜欢那样。
Am I doing something wrong? How can I remove the warning?
难道我做错了什么？我怎样才能消除警告？

I guess you have to rename the field, but you can do it in an transparent way:
我想您必须重命名该字段，但您可以以透明的方式进行：
@Entity
public class BaseAuthority implements GrantedAuthority {
private static final long serialVersionUID = 1L;
@Enumerated(EnumType.STRING)
@Column(unique = true, name = "authority")
private AuthorityType authorityType;
AuthorityType getAuthorityType() {
return authorityType;
}
@Override
public String getAuthority() {
return authorityType.toString();
}
}
and change your repository to
并将您的存储库更改为
@Repository
public interface BaseAuthorityRepository extends JpaRepository<BaseAuthority, Long> {
BaseAuthority findByAuthorityType(AuthorityType authority);
}
